Subject: [PATCH 4/6] [PATCH][clang] Prefer gcc toolchains with libgcc_s.so
|
||||
when not static linking libgcc
|
||||
|
||||
Fedora ships cross-compilers on all platforms, so a user could end up
|
||||
with a gcc x86_64 cross-compiler installed on an x86_64 system. clang
|
||||
maintains a list of supported triples for each target and when all
|
||||
else is equal will prefer toolchains with triples that appear earlier
|
||||
in the list.
|
||||
|
||||
The cross-compiler triple on Fedora is x86_64-linux-gnu and this comes
|
||||
before the Fedora system compiler's triple: x86_64-redhat-linux in
|
||||
the triples list, so the cross compiler is always preferred. This
|
||||
is a problem, because the cross compiler is missing libraries, like
|
||||
libgcc_s.so, that clang expects to be there so linker invocations
|
||||
will fail.
|
||||
|
||||
This patch fixes this by checking for the existence of libgcc_s.so
|
||||
when it is required and taking that into account when selecting a
|
||||
toolchain.
