Problems installing i-adhore

[giovannaVeiga]

Hello,

I was installing i-adhore in my lab's server and no issues were reported during the process. However when I try to run the example I get the following error message:
i-adhore: error while loading shared libraries: libmpi_cxx.so.40: cannot open shared object file: No such file or directory

Any ideas about what's wrong?

Thanks in advance

Have you tried running the example by forcing it to run single-threaded?
The libmpi library is used for parallellization (see section 3.3 of the documentation), and normally iadhore should detect the presence/absence of mpi (and disable multi-threading if mpi is not present). However, there appears to be going something wrong there.
Another solution would be of course to try and install the mpi library.

Hello,

normally iadhore should detect the presence/absence of mpi

It seems however that the current CMakeLists.txt returns an error when MPI is not available (at least on my machine (debian 12)).

CMake Error in i-ADHoRe/build/CMakeFiles/CMakeScratch/TryCompile-Fk3FJ9/CMakeLists.txt:
  Imported target "MPI::MPI_C" includes non-existent path

I had to install libopenmpi-dev to solve this issue.

Maybe you should either state that MPI is indeed required or change the CMakeLists.txt to ensure that a failure of FindMPI.cmake does not halt the cmake process.
