# This file is part of the package-notes package.

# Add an ELF note with information about the package the code was compiled for.

# See https://fedoraproject.org/wiki/Changes/Package_information_on_ELF_objects

# To opt out of the use of this feature completely, include this in
|
|
# the spec file:
|
|
#
|
|
# %undefine _package_note_file
|
|
#
|
|
# The other macros can be undefined too to replace parts of the
|
|
# functionality. If %_generate_package_note_file is undefined, the
|
|
# linker script will not be generated, but the link flags may still
|
|
# refer to it. This may be useful if the default generation method is
|
|
# insufficient and a different mechanism will be used to generate
|
|
# %_package_note_file. If %_package_note_flags is undefined, the
|
|
# linker argument that injects the script will not be added to
|
|
# %build_ldfags, but the linker script would still be generated.
|
|
|
|
# The name of the file with the linker script. If %{buildsubdir} is
|
|
# defined, the file will be placed therein. Otherwise, one level up,
|
|
# directly in %{_builddir}.
|
|
#
|
|
# Note that %{version}-%{release} used here might be redefined from
|
|
# the "primary" values when subpackages with different version-release
|
|
# are specified. The contents of the script use the shell variable
|
|
# $RPM_PACKAGE_NAME, $RPM_PACKAGE_VERSION, $RPM_PACKAGE_RELEASE,
|
|
# and $RPM_ARCH that are set early and seem to always contain the "primary"
|
|
# values for the main package.
