Good afternoon
I’m trying to compile NEMO 4.2.2 on a machine that only has the latest Intel compilers (v 2024.2). With the new versions, the names of the compilers have changed as follows:
icc → icx
ifort → ifx
As I understand, quite a few flags etc have changed with this switch. I managed to get XIOS to compile, but I’m failing on NEMO.
The final error is:
gmake: *** No rule to make target ‘nemogcm.o’, needed by ‘nemo.o’. Stop.
gmake -f /scratch/usr/shkjocke/models_p3/focioifs-4.0/nemo-ORCA05_Z46_SI3_COUPLED/cfgs/ORCA05_Z46_SI3_COUPLED/BLD/Makefile -j 1 all failed (2) at /scratch/usr/shkjocke/models_p3/focioifs-4.0/nemo-ORCA05_Z46_SI3_COUPLED/ext/FCM/bin/…/lib/Fcm/Build.pm line 597.

but before that, I get a lot of messages like this:

I had a look and I could not find that the “-C”, “-P”, or “-D” flags have changed at all from icc/ifort to icx/ifx.

I’m a bit lost. Has anyone else managed to compile NEMO with the new “icx” and “ifx” compilers? Is there anything major that I need to change in the arch file? I did not change the arch file since the older Intel versions.
Many thanks
