build issues with ASAGI

[seismo-mcfishin]

Hello,

I am helping a developer build ASAGI on a cluster and when running cmake, it looks like the path to ASAGI isn't being found.

Speficically, we obtain an error that says:

Package 'asagi', required by 'virtual:world', not found

We are at the "Run cmake, and compile with:" point of this of the "Installing ASAGI" step https://seissol.readthedocs.io/en/latest/asagi.html#installing-asagi

thanks!

During the ASAGI build:

• Did you specify -DCMAKE_INSTALL_PREFIX=$HOME for cmake?
• If yes, can you please check if e.g. $HOME/lib/pkgconfig/asagi.pc exists and paste the content here.

During the SeisSol build:

• Did you specify -DCMAKE_PREFIX_PATH=$HOME for cmake?

Asagi doesn't use the (sane) cmake FindPackage mechanism but rather uses pkg-config. So, you may need to include the file asagi.pc in the PKG_CONFIG_PATH.

Thanks for the suggestions!

So we are building SeisSol as a container on a cluster.

Everything is being installed at /sw/pkgs/lsa/SeisSol/SeisSol-122022 and we made sure /sw/pkgs/lsa/SeisSol/SeisSol-122022/lib/pkgconfig/asagi.pc exists.

-DCMAKE_PREFIX_PATH=/sw/pkgs/lsa/SeisSol/SeisSol-122022 was also added.

Our new error is this after trying to re-build:

If you want to see some details, how we installed SeisSol in a container, you can have a look at our Training repository: https://github.com/SeisSol/Training/blob/main/Dockerfile.

It seems to me that now your yaml-cpp installation is not working. How did you install yaml-cpp? You can use this patch to get some debug output about yaml-cpp during SeisSol's cmake step:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index 32905bcb..0d9573c5 100644

 if (EIGEN3_INCLUDE_DIR)

Also, you could check your/build/directory/CMakeFiles/SeisSol-bin.dir/link.txt. It holds the information, how everything (and in particular yaml-cpp) is linked. In my case, cmake decided to link yaml-cpp directly: /usr/lib64/libyaml-cpp.so.0.6.3.

If it is helpful...
I built a SeisSol enviornment in Spack. I ran into some trouble using the developers' seissol-env package (environment builds fine, but I think I run into some binutils conflicts -- which are almost certainly, when I try to compile SeisSol). But building all the dependencies in a Spack environment, producing LMOD modules, then loading those modules and compiling SeisSol works pretty well.

I build easi with asagi, then I prepend my cmake command with (amongst other variable definitions...) easi_DIR=${EASI_ROOT}/lib64/cmake/easi; I define {package_name}_ROOT in all of my Spack built modules.

Besides the asagi module setting env variables (PATH, LD_LIBRARY_PATH, etc.). I expect setting that easi variable helps cmake and friends find asagi.
