Description Bertrand Jacquin 2016-09-05 20:47:38 UTC 
sys-devel/llvm-3.8.1-r2 on x86 failed to compile source code as per the following error:

$ cat > conftest.c << EOF
/* confdefs.h */
#define PACKAGE_NAME "terminology"
#define PACKAGE_TARNAME "terminology"
#define PACKAGE_VERSION "0.9.99"
#define PACKAGE_STRING "terminology 0.9.99"
#define PACKAGE_BUGREPORT "enlightenment-devel@lists.sourceforge.net"
#define PACKAGE_URL ""
#define PACKAGE "terminology"
#define VERSION "0.9.99"
/* end confdefs.h.  */

int
main ()
{

  ;
  return 0;
}
EOF

$ clang ./conftest.c 
/usr/bin/i686-pc-linux-gnu-ld: cannot find /usr/bin/../lib/clang/3.8.1/lib/linux/libclang_rt.builtins-i686.a: No such file or directory
i686-pc-linux-gnu-clang-3.8: error: linker command failed with exit code 1 (use -v to see invocation)

clang is looking for libclang_rt.builtins-i686.a but only libclang_rt.builtins-i386.a exist:

$ qlist llvm | fgrep libclang_rt.builtins
/usr/lib/clang/3.8.1/lib/linux/libclang_rt.builtins-i386.a


Reproducible: Always

I think it's unhappy with our i686- CHOST. The code for finding clangrt is kinda poor in the driver. Could you paste 'clang --version' to confirm? I will try to find some solution upstream when I have time for it but can't promise that'd happen anytime soon.
