Dear Martin,
I guess I was being overly enthusiastic. I understand now, every "failed
test" (e.g. DEAL_II_HAVE_CXX20_FEATURES) end up in this file.
The majority of the "errors" I get are thus regular configuration "failure"
The final failure I get is related to : Performing C++ SOURCE FILE Test
DEAL_II_HAVE_USABLE_FLAGS_DEBUG failed with the following output:
Change Dir: /home/blaisbru/dealii/build/CMakeFiles/CMakeTmp
It's a massive error message, but the key line appear to be these one to me:
/cvmfs/soft.computecanada.ca/easybuild/software/2020/avx2/MPI/gcc9/openmpi4/trilinos/13.0.1/lib/libzadelus.so:
error: undefined reference to 'Adelus::nprocs_col'
/cvmfs/soft.computecanada.ca/easybuild/software/2020/avx2/MPI/gcc9/openmpi4/trilinos/13.0.1/lib/libzadelus.so:
error: undefined reference to 'Adelus::me'
/cvmfs/soft.computecanada.ca/easybuild/software/2020/avx2/MPI/gcc9/openmpi4/trilinos/13.0.1/lib/libzadelus.so:
error: undefined reference to 'Adelus::nprocs_row'
collect2: error: ld returned 1 exit status
gmake[1]: *** [CMakeFiles/cmTC_c4ee5.dir/build.make:266: cmTC_c4ee5] Error 1
gmake[1]: Leaving directory
'/home/blaisbru/dealii/build/CMakeFiles/CMakeTmp'
gmake: *** [Makefile:121: cmTC_c4ee5/fast] Error 2
Source file was:
int main(){ return 0; }
Is Adelus a Trilinos component that is mandatory? In my case, this is
clearly the issue, if this component is not there, then that's why I am
getting this error.
Thank you very much for the help! This community is always so amazing.
