icpc (Version 2021.6.0()fails with "internal error: 0_76" while compiling a GROMACS source

[GerardoC]

While building GROMACS (hwe-release-2022), using icpc (either Version 2021.6.0 Build 20220226_000000 or Version 2021.4.0 Build 20210910_000000), my build stops with:

[ 94%] Building CXX object api/nblib/CMakeFiles/nblib.dir/topology.cpp.o
": internal error: 0_76

compilation aborted for /global/scratch/groups/hpcperf/2022_Refresh/gromacs/api/nblib/topology.cpp (code 4)
make[2]: *** [api/nblib/CMakeFiles/nblib.dir/build.make:216: api/nblib/CMakeFiles/nblib.dir/topology.cpp.o] Error 4

What is 'internal error: 0_76"?  It is not particularly descriptive.  Unfortunately, the build is under the control of cmake, and "make V=1" doesn't make the output more verbose.

Hi,

Thanks for posting in Intel Communities.

GROMACS supports the Intel LLVM compilers (icx/icpx) and no longer supports Intel classic compilers (icc/icpc) .

We have tried with icpx compiler at our end and successfully installed GROMACS using icpx compiler. Could you please try with icpx compiler and get back to us.

If this resolves your issue, make sure to accept this as a solution. This would help others with a similar issue. Thank You!

Thanks & Regards,
