Description Gregor Jasny 2015-10-06 20:48:27 UTC
Description of problem:
  In our build scripts we point cmake to the DTS compiler by using the absolute path (/opt/rh/devtoolset-3/root/usr/bin/gcc).

  If we now add -fuse-ld=gold it cannot find the linker:

  collect2: fatal error: cannot find 'ld'

Version-Release number of selected component (if applicable):

  devtoolset-3-gcc-4.9.2-6.el6.x86_64

How reproducible:

  always

Steps to Reproduce:
0. Do not have devtoolset in PATH
1. echo 'int main() { return 0; }' > main.c
2. /opt/rh/devtoolset-3/root/usr/bin/gcc -fuse-ld=gold main.c

Actual results:

  collect2: fatal error: cannot find 'ld'

Expected results:

  links without problems

Additional info:

  An strace shows the following (linker related):

10360 stat("/usr/opt/rh/devtoolset-3/root/usr/bin/../libexec/gcc/x86_64-redhat-linux/4.9.2/ld.gold", 0x7fff40df82b0) = -1 ENOENT (No such file or directory)
10360 stat("/usr/opt/rh/devtoolset-3/root/usr/bin/../libexec/gcc/ld.gold", 0x7fff40df82b0) = -1 ENOENT (No such file or directory)

  So the problem should be gone if gcc would provide in x86_64-redhat-linux/4.9.2 not only a symlink to ld but also to ld.gold and ld.bfd. If I create the symlink there manually it works as expected.


Could you please provide the needed symlinks?

Thanks,
Gregor

Forgot to add: This is a RHEL6 host.

One could work around by setting the search path with -B
