This document contains documentation of the individual compiler flags
and how to use them.
[TOC]
# Using RPM build flags
For packages which use autoconf to set up the build environment, use
the `%configure` macro to obtain the full complement of flags, like
this:
%configure
This will invoke the `./configure` with arguments (such as
`--prefix=/usr`) to adjust the paths to the packaging defaults.
Prior to that, some common problems in autotools scripts are
automatically patched across the source tree.
As a side effect, this will set the environment variables `CFLAGS`,
`CXXFLAGS`, `FFLAGS`, `FCFLAGS`, `LDFLAGS` and `LT_SYS_LIBRARY_PATH`,
so they can be used by makefiles and other build tools. (However,
existing values for these variables are not overwritten.)
If your package does not use autoconf, you can still set the same
environment variables using
%set_build_flags
early in the `%build` section. (Again, existing environment variables
are not overwritten.) `%set_build_flags` does not perform autotools
script rewriting, unlike `%configure`.
Individual build flags are also available through RPM macros:
* `%{build_cflags}` for the C compiler flags (also known as the
`CFLAGS` variable). Also historically available as `%{optflags}`.
Furthermore, at the start of the `%build` section, the environment
variable `RPM_OPT_FLAGS` is set to this value.
* `%{build_cxxflags}` for the C++ compiler flags (usually assigned to
the `CXXFLAGS` shell variable).
* `%{build_fflags} for `FFLAGS` (the Fortran compiler flags, also
known as the `FCFLAGS` variable).
* `%{build_ldflags}` for the link editor (ld) flags, usually known as
`LDFLAGS`. Note that the contents quotes linker arguments using
`-Wl`, so this variable is intended for use with the `gcc` compiler
driver. At the start of the `%build` section, the environment
variable `RPM_LD_FLAGS` is set to this value.
The variable `LT_SYS_LIBRARY_PATH` is defined here to prevent the `libtool`
script (v2.4.6+) from hardcoding %_libdir into the binaries' RPATH.
These RPM macros do not alter shell environment variables.
For some other build tools separate mechanisms exist:
* CMake builds use the the `%cmake` macro from the `cmake-rpm-macros`
package.
Care must be taking not to compile the current selection of compiler
flags into any RPM package besides `redhat-rpm-config`, so that flag
changes are picked up automatically once `redhat-rpm-config` is
updated.
# Flag selection for the build type
The default flags are suitable for building applications.
For building shared objects, you must compile with `-fPIC` in
(`CFLAGS` or `CXXFLAGS`) and link with `-shared` (in `LDFLAGS`).
For other considerations involving shared objects, see:
* [Fedora Packaging Guidelines: Shared Libraries](https://docs.fedoraproject.org/en-US/packaging-guidelines/#_shared_libraries)
# Customizing compiler and other build flags
It is possible to set RPM macros to change some aspects of the
compiler flags. Changing these flags should be used as a last
recourse if other workarounds are not available.
### Toolchain selection
The default toolchain uses GCC, and the `%toolchain` macro is defined
as `gcc`.
It is enough to override `toolchain` macro and all relevant macro for C/C++
compilers will be switched. Either in the spec or in the command-line.
%global toolchain clang
or:
rpmbuild -D "toolchain clang" …
Inside a spec file it is also possible to determine which toolchain is in use
by testing the same macro. For example:
%if "%{toolchain}" == "gcc"
BuildRequires: gcc
%endif
or:
%if "%{toolchain}" == "clang"
BuildRequires: clang compiler-rt
%endif
### Disable autotools compatibility patching
By default, the invocation of the `%configure` macro replaces
`config.guess` files in the source tree with the system version. To
disable that, define this macro:
%global _configure_gnuconfig_hack 0
`%configure` also patches `ltmain.sh` scripts, so that linker flags
are set as well during libtool-. This can be switched off using:
%global _configure_libtool_hardening_hack 0
Further patching happens in LTO mode, see below.
### Disabling Link-Time Optimization
By default, builds use link-time optimization. In this build mode,
object code is generated at the time of the final link, by combining
information from all available translation units, and taking into
account which symbols are exported.
To disable this optimization, include this in the spec file:
%define _lto_cflags %{nil}
If LTO is enabled, `%configure` applies some common required fixes to
`configure` scripts. To disable that, define the RPM macro
`_fix_broken_configure_for_lto` as `true` (sic; it has to be a shell
command).
### Lazy binding
If your package depends on the semantics of lazy binding (e.g., it has
plugins which load additional plugins to complete their dependencies,
before which some referenced functions are undefined), you should put
`-Wl,-z,lazy` at the end of the `LDFLAGS` setting when linking objects
which have such requirements. Under these circumstances, it is
unnecessary to disable hardened builds (and thus lose full ASLR for
executables), or link everything without `-Wl,z,now` (non-lazy
binding).
### Hardened builds
By default, the build flags enable fully hardened builds. To change
this, include this in the RPM spec file:
%undefine _hardened_build
This turns off certain hardening features, as described in detail
below. The main difference is that executables will be
position-dependent (no full ASLR) and use lazy binding.
### Annotated builds/watermarking
By default, the build flags cause a special output section to be
included in ELF files which describes certain aspects of the build.
To change this for all compiler invocations, include this in the RPM
spec file:
%undefine _annotated_build
Be warned that this turns off watermarking, making it impossible to do
full hardening coverage analysis for any binaries produced.
It is possible to disable annotations for individual compiler
invocations, using the `-fplugin-arg-annobin-disable` flag. However,
the annobin plugin must still be loaded for this flag to be
recognized, so it has to come after the hardening flags on the command
line (it has to be added at the end of `CFLAGS`, or specified after
the `CFLAGS` variable contents).
### Keeping dependencies on unused shared objects
By default, ELF shared objects which are listed on the linker command
line, but which have no referencing symbols in the preceding objects,
are not added to the output file during the final link.
In order to keep dependencies on shared objects even if none of
their symbols are used, include this in the RPM spec file:
%undefine _ld_as_needed
For example, this can be required if shared objects are used for their
side effects in ELF constructors, or for making them available to
dynamically loaded plugins.
### Strict symbol checks in the link editor (ld)
Optionally, the link editor will refuse to link shared objects which
contain undefined symbols. Such symbols lack symbol versioning
information and can be bound to the wrong (compatibility) symbol
version at run time, and not the actual (default) symbol version which
would have been used if the symbol definition had been available at
static link time. Furthermore, at run time, the dynamic linker will
not have complete dependency information (in the form of DT_NEEDED
entries), which can lead to errors (crashes) if IFUNC resolvers are
executed before the shared object containing them is fully relocated.
To switch on these checks, define this macro in the RPM spec file:
%define _strict_symbol_defs_build 1
If this RPM spec option is active, link failures will occur if the
linker command line does not list all shared objects which are needed.
In this case, you need to add the missing DSOs (with linker arguments
such as `-lm`). As a result, the link editor will also generated the
necessary DT_NEEDED entries.
In some cases (such as when a DSO is loaded as a plugin and is
expected to bind to symbols in the main executable), undefined symbols
are expected. In this case, you can add
%undefine _strict_symbol_defs_build
to the RPM spec file to disable these strict checks. Alternatively,
you can pass `-z undefs` to ld (written as `-Wl,-z,undefs` on the gcc
command line). The latter needs binutils 2.29.1-12.fc28 or later.
### Legacy -fcommon
Since version 10, [gcc defaults to `-fno-common`](https://gcc.gnu.org/gcc-10/porting_to.html#common).
Builds may fail with `multiple definition of ...` errors.
As a short term workaround for such failure,
it is possible to add `-fcommon` to the flags by defining `%_legacy_common_support`.
%define _legacy_common_support 1
Properly fixing the failure is always preferred!
### Post-build ELF object processing
By default, DWARF debugging information is separated from installed
ELF objects and put into `-debuginfo` subpackages. To disable most
debuginfo processing (and thus the generation of these subpackages),
define `_enable_debug_packages` as `0`.
Processing of debugging information is controlled using the
`find-debuginfo` tool from the `debugedit` package. Several aspects
of its operation can be controlled at the RPM level.
* Creation of `-debuginfo` subpackages is enabled by default.
To disable, undefine `_debuginfo_subpackages`.
* Likewise, `-debugsource` subpackages are automatically created.
To disable, undefine `_debugsource_subpackages`.
See [Separate Subpackage and Source Debuginfo](https://fedoraproject.org/wiki/Changes/SubpackageAndSourceDebuginfo)
for background information.
* `_build_id_links`, `_unique_build_ids`, `_unique_debug_names`,
`_unique_debug_srcs` control how debugging information and
corresponding source files are represented on disk.
See `/usr/lib/rpm/macros` for details. The defaults
enable parallel installation of `-debuginfo` packages for
different package versions, as described in
[Parallel Installable Debuginfo](https://fedoraproject.org/wiki/Changes/ParallelInstallableDebuginfo).
* By default, a compressed symbol table is preserved in the
`.gnu_debugdata` section. To disable that, undefine
`_include_minidebuginfo`.
* To speed up debuggers, a `.gdb_index` section is created. It can be
disabled by undefining `_include_gdb_index`.
* Missing build IDs result in a build failure. To ignore such
problems, undefine `_missing_build_ids_terminate_build`.
* During processing, build IDs are recomputed to match the binary
content. To skip this step, define `_no_recompute_build_ids` as `1`.
* By default, the options in `_find_debuginfo_dwz_opts` turn on `dwz`
(DWARF compression) processing. Undefine this macro to disable this
step.
* Additional options can be passed by defining the
`_find_debuginfo_opts` macro.
After separation of debugging information, additional transformations
are applied, most of them also related to debugging information.
These steps can be skipped by undefining the corresponding macros:
* `__brp_strip`: Removal of leftover debugging information. The tool
specified by the `__strip` macro is invoked with the `-g` option on
ELF object (`.o`) files.
* `__brp_strip_static_archive`: This is similar to `__brp_strip`, but
processes static `.a` archives instead.
* `__brp_strip_comment_note`: This step removes unallocated `.note`
sections, and `.comment` sections from ELF files.
* `__brp_strip_lto`: This step removes GCC LTO intermediate representation
in ELF sections starting with `.gnu.lto_` and `.gnu.debuglto_`. Skipping
this step is strongly discouraged because the tight coupling of LTO
data with the GCC version. The underlying tool is again determined by the
`__strip` macro.
* `__brp_llvm_compile_lto_elf`: This step replaces LLVM bitcode files
with object files, thereby removing LLVM bitcode from the installed
files. This transformation is applied to object files in static `.a`
archives, too.
* `__brp_ldconfig`: For each shared object on the library search path
whose soname does not match its file name, a symbolic link from the
soname to the file name is created. This way, these shared objects
are loadable immediately after installation, even if they are not yet
listed in the `/etc/ld.so.cache` file (because `ldconfig` has not been
invoked yet).
# Individual compiler flags
Compiler flags end up in the environment variables `CFLAGS`,
`CXXFLAGS`, `FFLAGS`, and `FCFLAGS`.
The general (architecture-independent) build flags are:
* `-O2`: Turn on various GCC optimizations. See the [GCC manual](https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-O2).
Optimization improves performance, the accuracy of warnings, and the
reach of toolchain-based hardening, but it makes debugging harder.
* `-g`: Generate debugging information (DWARF). In Fedora, this data
is separated into `-debuginfo` RPM packages whose installation is
optional, so debuging information does not increase the size of
installed binaries by default.
* `-pipe`: Run compiler and assembler in parallel and do not use a
temporary file for the assembler input. This can improve
compilation performance. (This does not affect code generation.)
* `-Wall`: Turn on various GCC warnings.
See the [GCC manual](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wall).
* `-Werror=format-security`: Turn on format string warnings and treat
them as errors.
See the [GCC manual](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wformat-security).
This can occasionally result in compilation errors. In this case,
the best option is to rewrite the source code so that only constant
format strings (string literals) are used.
* `-Wp,-D_FORTIFY_SOURCE=2`: Source fortification activates various
hardening features in glibc:
* String functions such as `memcpy` attempt to detect buffer lengths
and terminate the process if a buffer overflow is detected.
* `printf` format strings may only contain the `%n` format specifier
if the format string resides in read-only memory.
* `open` and `openat` flags are checked for consistency with the
presence of a *mode* argument.
* Plus other minor hardening changes.
(These changes can occasionally break valid programs.)
* `-fexceptions`: Provide exception unwinding support for C programs.
See the [`-fexceptions` option in the GCC
manual](https://gcc.gnu.org/onlinedocs/gcc/Code-Gen-Options.html#index-fexceptions)
and the [`cleanup` variable
attribute](https://gcc.gnu.org/onlinedocs/gcc/Common-Variable-Attributes.html#index-cleanup-variable-attribute).
This also hardens cancellation handling in C programs because
it is not required to use an on-stack jump buffer to install
a cancellation handler with `pthread_cleanup_push`. It also makes
it possible to unwind the stack (using C++ `throw` or Rust panics)
from C callback functions if a C library supports non-local exits
from them (e.g., via `longjmp`).
* `-fasynchronous-unwind-tables`: Generate full unwind information
covering all program points. This is required for support of
asynchronous cancellation and proper unwinding from signal
handlers. It also makes performance and debugging tools more
useful because unwind information is available without having to
install (and load) debugging information.
* `-Wp,-D_GLIBCXX_ASSERTIONS`: Enable lightweight assertions in the
C++ standard library, such as bounds checking for the subscription
operator on vectors. (This flag is added to both `CFLAGS` and
`CXXFLAGS`; C compilations will simply ignore it.)
* `-fstack-protector-strong`: Instrument functions to detect
stack-based buffer overflows before jumping to the return address on
the stack. The *strong* variant only performs the instrumentation
for functions whose stack frame contains addressable local
variables. (If the address of a variable is never taken, it is not
possible that a buffer overflow is caused by incorrect pointer
arithmetic involving a pointer to that variable.)
* `-fstack-clash-protection`: Turn on instrumentation to avoid
skipping the guard page in large stack frames. (Without this flag,
vulnerabilities can result where the stack overlaps with the heap,
or thread stacks spill into other regions of memory.) This flag is
fully ABI-compatible and has adds very little run-time overhead.
This flag is currently not available on aarch64 with the `clang` toolchain.
* `-flto=auto`: Enable link-time optimization (LTO), using `make` job server
integration for parallel processing. (`gcc` toolchain only)
* `-ffat-lto-objects`: Generate EFL object files which contain both
object code and LTO intermediate representation. (`gcc` toolchain only)
* `-flto`: Enable link-time optimization. (`clang` toolchain only)
* `-grecord-gcc-switches`: Include select GCC command line switches in
the DWARF debugging information. This is useful for detecting the
presence of certain build flags and general hardening coverage.
* `-fcommon`: This optional flag is used to build legacy software
which relies on C tentative definitions. It is disabled by default.
For hardened builds (which are enabled by default, see above for how
to disable them), the flag
`-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1` is added to the
command line. It adds the following flag to the command line:
* `-fPIE`: Compile for a position-independent executable (PIE),
enabling full address space layout randomization (ASLR). This is
similar to `-fPIC`, but avoids run-time indirections on certain
architectures, resulting in improved performance and slightly
smaller executables. However, compared to position-dependent code
(the default generated by GCC), there is still a measurable
performance impact.
If the command line also contains `-r` (producing a relocatable
object file), `-fpic` or `-fPIC`, this flag is automatically
dropped. (`-fPIE` can only be used for code which is linked into
the main program.) Code which goes into static libraries should be
compiled with `-fPIE`, except when this code is expected to be
linked into DSOs, when `-fPIC` must be used.
To be effective, `-fPIE` must be used with the `-pie` linker flag
when producing an executable, see below.
To support [binary watermarks for ELF
objects](https://fedoraproject.org/wiki/Toolchain/Watermark) using
annobin, the `-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1` flag is
added by default (with the `gcc` toolchain). This can be switched off
by undefining the `%_annotated_build` RPM macro (see above). Binary
watermarks are currently disabled with the `clang` toolchain.
### Architecture-specific compiler flags
These compiler flags are enabled for all builds (hardened/annotated or
not), but their selection depends on the architecture:
* `-fcf-protection`: Instrument binaries to guard against
ROP/JOP attacks. Used on i686 and x86_64.
* `-m64` and `-m32`: Some GCC builds support both 32-bit and 64-bit in
the same compilation. For such architectures, the RPM build process
explicitly selects the architecture variant by passing this compiler
flag.
In addition, `redhat-rpm-config` re-selects the built-in default
tuning in the `gcc` package. These settings are:
* **i686**: `-march=i686` is used to select a minmum support CPU level
of i686 (corresponding to the Pentium Pro). SSE2 support is
enabled with `-msse2` (so only CPUs with SSE2 support can run the
compiled code; SSE2 was introduced first with the Pentium 4).
`-mtune=generic` activates tuning for a current blend of CPUs
(under the assumption that most users of i686 packages obtain them
through an x86_64 installation on current hardware).
`-mfpmath=sse` instructs GCC to use the SSE2 unit for floating
point math to avoid excess precision issues. `-mstackrealign`
avoids relying on the stack alignment guaranteed by the current
version of the i386 ABI.
* **ppc64le**: `-mcpu=power9 -mtune=power9` selects a minimum supported
CPU level of POWER9.
* **s390x**: `-march=z14 -mtune=z15` specifies a minimum supported CPU
level of z14, while optimizing for a subsequent CPU generation
(z15).
* **x86_64**: `-march=x86-64-v2 -mtune=generic` builds for the
[x86-64-v2 micro-architecture level](https://gitlab.com/x86-psABIs/x86-64-ABI/-/blob/master/x86-64-ABI/low-level-sys-info.tex)
and selects tuning which is expected to beneficial for a broad range
of current CPUs.
* **aarch64** does not have any architecture-specific tuning.
# Individual linker flags
Linker flags end up in the environment variable `LDFLAGS`.
The linker flags listed below are injected. Note that they are
prefixed with `-Wl` because it is expected that these flags are passed
to the compiler driver `gcc`, and not directly to the link editor
`ld`.
* `-z relro`: Activate the *read-only after relocation* feature.
Constant data and relocations are placed on separate pages, and the
dynamic linker is instructed to revoke write permissions after
dynamic linking. Full protection of relocation data requires the
`-z now` flag (see below).
* `--as-needed`: In the final link, only generate ELF dependencies
for shared objects that actually provide symbols required by the link.
Shared objects which are not needed to fulfill symbol dependencies
are essentially ignored due to this flag.
* `-z defs`: Refuse to link shared objects (DSOs) with undefined symbols
(optional, see above).
For hardened builds, the
`-specs=/usr/lib/rpm/redhat/redhat-hardened-ld` flag is added to the
compiler driver command line. (This can be disabled by undefining the
`%_hardened_build` macro; see above) This activates the following
linker flags:
* `-pie`: Produce a PIE binary. This is only activated for the main
executable, and only if it is dynamically linked. This requires
that all objects which are linked in the main executable have been
compiled with `-fPIE` or `-fPIC` (or `-fpie` or `-fpic`; see above).
By itself, `-pie` has only a slight performance impact because it
disables some link editor optimization, however the `-fPIE` compiler
flag has some overhead.
* `-z now`: Disable lazy binding and turn on the `BIND_NOW` dynamic
linker feature. Lazy binding involves an array of function pointers
which is writable at run time (which could be overwritten as part of
security exploits, redirecting execution). Therefore, it is
preferable to turn of lazy binding, although it increases startup
time.
# Support for extension builders
Some packages include extension builders that allow users to build
extension modules (which are usually written in C and C++) under the
control of a special-purpose build system. This is a common
functionality provided by scripting languages such as Python and Perl.
Traditionally, such extension builders captured the Fedora build flags
when these extension were built. However, these compiler flags are
adjusted for a specific Fedora release and toolchain version and
therefore do not work with a custom toolchain (e.g., different C/C++
compilers), and users might want to build their own extension modules
with such toolchains.
The macros `%{extension_cflags}`, `%{extension_cxxflags}`,
`%{extension_fflags}`, `%{extension_ldflags}` contain a subset of
flags that have been adjusted for compatibility with alternative
toolchains, while still preserving some of the compile-time security
hardening that the standard Fedora build flags provide.
The current set of differences are:
* No GCC plugins (such as annobin) are activated.
* No GCC spec files (`-specs=` arguments) are used.
Additional flags may be removed in the future if they prove to be
incompatible with alternative toolchains.
Extension builders should detect whether they are performing a regular
RPM build (e.g., by looking for an `RPM_OPT_FLAGS` variable). In this
case, they should use the *current* set of Fedora build flags (that
is, the output from `rpm --eval '%{build_cflags}'` and related
commands). Otherwise, when not performing an RPM build, they can
either use hard-coded extension builder flags (thus avoiding a
run-time dependency on `redhat-rpm-config`), or use the current
extension builder flags (with a run-time dependency on
`redhat-rpm-config`).
As a result, extension modules built for Fedora will use the official
Fedora build flags, while users will still be able to build their own
extension modules with custom toolchains.

Usage: gpgverify --keyring=<pathname> --signature=<pathname> --data=<pathname>
gpgverify is a wrapper around gpgv designed for easy and safe scripting. It
verifies a file against a detached OpenPGP signature and a keyring. The keyring
shall contain all the keys that are trusted to certify the authenticity of the
file, and must not contain any untrusted keys.
The differences, compared to invoking gpgv directly, are that gpgverify accepts
the keyring in either ASCII-armored or unarmored form, and that it will not
accidentally use a default keyring in addition to the specified one.
Parameters:
--keyring=<pathname> keyring with all the trusted keys and no others
--signature=<pathname> detached signature to verify
--data=<pathname> file to verify against the signature

# If defined, _configure_disable_silent_rules will cause --disable-silent-rules
# to be added to the list of options passed to the configure script.
# Eventually we'll want to turn this on by default, but this gives packagers a
# way to turn it back off.
# %_configure_disable_silent_rules 1
# This fixes various easy resolved configure tests that are compromised by LTO.
#
# We use this within the standard %configure macro, but also make it available
# for packages which don't use %configure
#
# The first three are common ways to test for the existence of a function, so
# we ensure the reference to the function is preserved
#
# The fourth are constants used to then try to generate NaNs and other key
# floating point numbers. We then use those special FP numbers to try and
# raise a SIGFPE. By declaring x & y volatile we prevent the optimizers
# from removing the computation
#
# The fifth (and worst) addresses problems with autoconf/libtool's approach
# to extracting symbols from .o files and generating C code. In an LTO world
# types matter much more closely and you can't have an object in one context
# that is a function definition and a simple scalar variable in another.
# Thankfully HP-UX has always had that restriction and is supported by
# autoconf/libtool. The insane sed script replaces the "generic" code with
# the HP-UX version.
#
# If we do not make changes, we put the original file back. This avoids
# unnecessary rebuilds of things that may have dependencies on the configure
# files.

# Decide which version of the annobin plugin for gcc should be used.
# There are two possible versions, one created by the annobin package and one
# created by the gcc package. The logic selects the gcc version unless both
# have been built by the same version of the compiler. In that case the
# annobin version is selected instead.
#
# The point of all this is that the annobin plugin is very sensitive to
# mismatches with the version of gcc that built it. If the plugin is built
# by version A of gcc, but then run on version B of gcc, it is possible for
# the plugin to misbehave, which then causes problems if gating tests examine
# the plugin's output. (This has happened more than once in RHEL...).
#
# So the plugin is built both by gcc and by the annobin package. This means
# that whenever gcc is updated a fresh plugin is built, and the logic below
# will select that version. But in order to allow annobin development to
# proceed independtently of gcc, the annobin package can also update its
# version of the plugin, and the logic will select this new version.
