Further investigation reveals this is specific to bulding gccjit - the
rest is compiling without issue.
Looks like https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64296
The suggested workaround - adding --with-pic to configure - seems to work.
However, --with-pic is not documented in
https://gcc.gnu.org/install/configure.html or in the output of
./configure --help

Hi,
I'm trying to build a gcc-5.3 package for rhel 6 x64 (based on
gcc-5.3.1 from koji) with the prerequisites in tree, as if after using
the contrib/download_prerequisites but with newer versions of those
libraries.
The exact error:
/opt/gnu/binutils/2.26/bin/ld:

Since gcc/configure doesn't accept -fPIC, I'm not sure how to proceed
- How do I tell gcc configure to pass -fPIC to just the isl library,
and only when building objlibgccjit?
Any help would be appreciated, thanks.
I'd like to mention that the installation failed with the versions
from contrib too
My current environment:
RHEL 6.7 x64
binutils 2.26 (compiled from source)
GMP 6.1.0
MPFR 3.1.3 (with latest "allpatches" applied)
MPC 1.0.3
ISL 0.16
My configure looks like:
