[BUG] Compiling with LLVM-based Intel MPI compilers (oneAPI)

[Diehl__Martin]

Describe the bug

configure stops with error. It is invoked with

./configure CC="mpiicc -cc=icx" CXX="mpiicpc -cxx=icpx" F90="mpiifort -fc=ifx" FC="mpiifort -fc=ifx" F77="mpiifort -fc=ifx" --enable-shared --enable-parallel --enable-fortran --with-zlib=yes --with-szlib=no

Expected behavior

Installation with Intel oneAPI LLVM compilers should be possible

Platform (please complete the following information)

• HDF5 1.12.2
• Arch Linux (Kernel 6.0.2-arch1-1)
• Intel oneAPI 2022.3.0.8767 (BaseKit + HPCKit)
• Gnu Make 4.3

Additional context

It seems that configure finds the classic intel compilers

• compiler 'mpiicc -cc=icx' is Intel icc-2022.2.0
• compiler 'mpiifort -fc=ifx' is Intel ifort-2022.2.0
• compiler 'mpiicpc -cxx=icpx' is Intel icpc-2022.2.0

Hi,

Thanks for posting in the Intel forums.

Could you please let us know if you are facing any errors while configuring HDF5 using the Intel oneAPI compilers(icx,icpx,ifx)?

Thanks & Regards,

./configure CC="mpiicc -cc=icc" CXX="mpiicpc -cxx=icpc" F90="mpiifort -fc=ifort" FC="mpiifort -fc=ifort" F77="mpiifort -fc=ifort" --enable-shared --enable-parallel --enable-fortran --with-zlib=yes --with-szlib=no

works. I think the issue is that the build system cannot discriminate the compilers and uses options or expects behavior that work for the traditional compilers but not for the new ones.

Hi,

Could you please confirm if you are facing a similar error as shown below? If not, please provide us a screenshot of the error you are facing.

I can confirm that. I think the interesting information is in the this statement from config.log:

/usr/bin/ld: cannot find -loopopt=1: No such file or director

to me it seems that there is a dash missing and it is interpreted as a single character statement -l='oopopt=1'
