PackageName: General Summary of the Question

[libm3l]

Hello

I was able to configure and compile trilinos. Then I try to compile another solver which uses trilinos functionality. I get an error message:

../../include/Epetra_ConfigDefs.h:108:10: fatal error: Epetra_config.h: No such file or directory

include

I checked and Epetra_config.h does not exist in my trilinos installation. It seems to me that Epetra_config.h is created by cmake. How can I re-create this file?

Thank you Adam J.

@libm3l Could you post the output from you CMake call? This looks like an incomplete configuration.

[libm3l]

Here is my configure command: /opt/cmake/cmake-3.27.4/bin/cmake -DTPL_ENABLE_MPI=ON -DCMAKE_INSTALL_PREFIX=$TRILINOS_ROOT -DTrilinos_ENABLE_Sacado=ON -DTrilinos_ENABLE_Pliris=OFF -DTrilinos_ENABLE_Kokkos=OFF -DBUILD_SHARED_LIBS=ON ../ -DTPL_ENABLE_BLAS=OFF

and attached is file with cmake output output_file.txt

[cgcgcg]

Looking at the file I see:

Epetra isn't enabled.

Thanks! I'll try to enable it

Ok. Feel free to post on this issue if you encounter difficulties. If the build does go through, please remember to close it.

[libm3l]

Just one question - how can I enable Epetra? I do not see any option in cmake --help. Thank you!

[cgcgcg]

-D Trilinos_ENABLE_Epetra=ON
-D Trilinos_ENABLE_EpetraExt=ON

should do the trick. You might have to enable BLAS as well. (Currently you're disabling it.)

[libm3l]

Thanks a lot!
