Dear Prof. Bangerth,
I expected it to take the default compiler. But for some reason it doesn't.
A bit of context on my machine and installation:
- I am trying to install this version of dealii using spack on a clean
(newly installed) OS - Ubuntu24.04.
- Installed dealii using the command "spack install dealii" using the
spack/develop branch to get the latest version of dealii (spack package was
recently released).
Nevertheless, i tried to use the default gcc compilers by setting the
following variables in the CMakeFiles.txt:
set(CMAKE_C_COMPILER "/usr/bin/gcc-13")
set(CMAKE_CXX_COMPILER "/usr/bin/g++-13")
Here's the output after this change:
omnipresent@dell:~/Documents/github_repos/spack/opt/spack/linux-ubuntu24.04-icelake/gcc-13.2.0/dealii-9.6.0-kt2qma7oea6a6vtupm4ho6lqkrirmcfz/share/deal.II/examples/step-1/build$

It looks like it compiled on the second "cmake .." command (surprising to
me). But then when i try to "make", it shows the linker error for which i
am unable to find a solution.
Can someone help with this?
Thanks
