gcc 8.1 + libc.a

[Dmitry Mikushin]

First of, "error opening libc.a" message looks highly unusual. It's not the
way ld typically complains about a missing library or wrong architecture.
More likely, here it is rather some gcc-internal lib.a to be deployed in
some special way, but was missing.

I would try two things:
1) Re-iterate the failing conftest manually, appending -v option to show
what underlying ld command is being executed
2) Search for libc.a in the gcc build tree on another server, where the
build was successful.

Good luck,
- Dmitry.

Hello,
I have successfully installed gcc 8.1 on one system. I had to build the
accelerator on the front end, because the compute nodes did not have libc.a.
The build process seems to require a libc.a.
I am now struggling with trying to install it on a different system: Same
concept, front end has libc.a, compute nodes don’t. But now I can’t even
build the build the accelerator compiler, because of of the missing libc.a.
But it lives in /usr/lib64, just like on the other system. Would you have
any advise how I can get around this? Thanks in advance,
Gabriele
