Hi Howard,

Thanks for replying. I am sorry, I did not have any luck with the suggestion.
There are no significant changes. I have attached the new config.log.gz file.
I suspect problems, perhaps, related to the symbolic link
ln -s /usr/lib64/libgcc_s.so.1 /usr/x86_64-linux-gnu/lib/libgcc_s.so.
So, please, do you have any other suggestions?

Regards,
Jorge.

Hi,

Could you try modifying your configure command to be something like this?

./configure CC=icx CXX=icpx FC=ifx CFLAGS="-O3" CXXFLAGS="-O3" FCFLAGS="-O3"

This works for me. I am using a somewhat older one api compiler suite however:

icx --version
Intel(R) oneAPI DPC++/C++ Compiler 2023.2.0 (2023.2.0.20230622)

Subject: [EXTERNAL] [OMPI users] configure failed of openmpi-5.0.10 with the 2026.0.0 icx and ifx compilers in Fedora 44


Der all,

I cannot configure openmpi-5.010 with the 2026.0.0 icx+ifx compilers in
Fedora Linux 44 (Workstation Edition) system (altough an alternative
version with gcc+gfortran is ok).

It is worth noting that during the installation of the icx/ifx compilers, I had to add the line:
ln -s /usr/lib64/libgcc_s.so.1 /usr/x86_64-linux-gnu/lib/libgcc_s.so.

Please, any suggestions on how to resolve the issues listed in the attached file?
Thank you in advance.

Regards.
Jorge D'Elia.
