Hi Jorge, Okay this looks more like its failing now with something that may be due to your workarounds for linking:
10349 configure:20091: checking if C and C++ are link compatible 10350 configure:20114: icx -c -O3 -DNDEBUG -finline-functions conftest_c.c 10351 configure:20117: $? = 0 10352 configure:20145: icpx -o conftest -DNDEBUG conftest.cpp conftest_c.o >&5 10353 /usr/x86_64-linux-gnu/bin/ld: cannot find -lstdc++: No such file or directory 10354 icpx: error: linker command failed with exit code 1 (use -v to see invocation) 10355 configure:20145: $? = 1 10356 configure: failed program was: I'd suggest trying to build some simple non-MPI c++ and c tests you build with icpx and icx respectively then try to link using icpx. This sounds like a problem better directed toward one of the One API community lists.

Ok. Then, I temporarily try with a new configuration: unset CC unset CXX unset FC options="CC=icx CXX=icpx FC=ifx --prefix=${PREFIX} --with-prrte=internal --with-pmix=internal --with-ucx --without-verbs --without-libfabric --without-xpmem" and I have attached the resulting config.log.gz file. THANKS.
