Question about the C API #5

Closed gkarpa closed 3 years ago

gkarpa commented 3 years ago

Hi all,

I would like to try and use espreso's FETI solver in a third party C++ project. I managed to build the library succesfully in Ubuntu 18.04 combined with some additional libraries (Intel MKL, Open-MPI, metis/parmetis, HYPRE, hdf5) and I included the API header (feti4i.h) in my project.

However, I eventually noticed (by nm *.so | grep -i FETI4I ) that the functions of the API are not contained in any of the .so that were produced by the build process. Their implementation is located in the src/omitted subfolder, which seems to be omitted during the build. My question then is, what is the intended usage of the C API? My guess is that I'm missing something, so please feel free to point me in the right direction.

Thanks a lot in advance for your time, and congratulations on your great work!

Regards, George

Dear George,

implementation was in omitted folder since it was not fully updated to internal structres. Please, update your espreso repository, it contains the implementation now. In addition, ''api/apitester.cpp" and "api/example.cpp" contain inlustration of usage.

Best Regards, Ondrej
