Build fails with ifx

[alex-robinson]

Hello,

A linking error occurs using the ifx (Intel OneAPI HPC toolkit) compiler to build lis. The error occurs at the end of the make step, if I do the following:

cd lis-2.1.6
./configure --prefix=$PWD/../2.1.6-ifx --enable-f90 --enable-omp CC=icx F77=ifx
make
...
ifx: command line warning #10435: option '-nofor_main' use with underscore is deprecated; use '-nofor-main' instead
ld: cannot find -loopopt=1
make[1]: *** [Makefile:736: esolve] Error 1

This error occurs with any version of ifx from 2022-2024.

I would note that it seems like it might be something in the settings of configuration script, as other libraries like fftw can be configured and compiled this way without issues. Or am I doing something wrong?

I hope this is helpful, and thank you for your work!

Cheers,
Alex

Hi,

Thank you for contacting us.
This is a known issue and we are waiting for Intel to release a new version of the compiler that does not use -loopopt. We hope you will be able to use ifort for the time being.

Sincerely,
Akira Nishida
