@DavidBurrows-NCO Which build errors do you see on Gaea?

[DavidBurrows-NCO]

@DusanJovic-NOAA

cd ufsm
module use modulefiles
module load ufs_gaea.intel
export CMAKE_FLAGS="-DAPP=ATM -DCCPP_SUITES=FV3_GFS_v16"
./build.sh

UFS MODEL DIR: /gpfs/f5/epic/scratch/David.Burrows/ufs_fails_to_build_on_gaea/ufsm
cmake: /opt/cray/pe/gcc/10.3.0/snos/lib64/libstdc++.so.6: version `GLIBCXX_3.4.30' not found (required by cmake)

This occurs because cmake is not loaded.

I see. It was loaded in the old ufs_gaea.intel.lua

https://github.com/ufs-community/ufs-weather-model/blob/f42e347b1cad15b4b2470fecb17cb19bb2d19459/modulefiles/ufs_gaea.intel.lua

@DusanJovic-NOAA hmm. Maybe I'm confused. If I look at the develop branch then cmake is not loaded: develop branch

[DusanJovic-NOAA]

It is not loaded now, but in the 'original' version of ufs_gaea.intel.lua (before c5 support was added) it was. The initial version of ufs_gaea-c5.intel.lua did not have it. Here https://github.com/ufs-community/ufs-weather-model/blob/f42e347b1cad15b4b2470fecb17cb19bb2d19459/modulefiles/ufs_gaea.intel.lua

Then maybe this line is not needed anymore:

ufs-weather-model/tests/rt.sh

Line 724 in 85d73f2

export LD_PRELOAD=/opt/cray/pe/gcc/12.2.0/snos/lib64/libstdc++.so.6

This was added as a quick fix for cmake issue, while in fact the problem was that cmake was not actually loaded from spack-stack installation.
