ngs-special-functions's Issues

Import Error

Hi,
I tried to build the package following the instruction but when I run the demo bessel.py I get an Import Error

ImportError: /python3.8/site-packages/ngsolve/special_functions.so: undefined symbol: _ZNK5ngfem19CoefficientFunction14GetDescriptionB5cxx11Ev

I am using ngsolve 6.2.2301, could it be a problem with the version of ngsolve?

mpi.h not found during compilation

Hi, I'm getting an error "mpi.h not found" when compiling this module on a Linux 3.10 shared server (Red Hat 4.8.5).

OpenMPI 2.0 is installed and "/act/openmpi-2.0/gcc-7.2.0/bin" is in my PATH
also "/act/openmpi-2.0/gcc-7.2.0/lib" is in my LD_LIBRARY_PATH

I believe the correct header file is located here
/act/openmpi-2.0/gcc-7.2.0/include/mpi.h

Is there a way I can patch one or both of the CMakeLists.txt files with a file() or include_directories() command to get this to compile -- or another solution?

Thanks!
Dow Drake

edit: as a workaround for my lack of Cmake knowledge, I simply copied mpi.h and mpi_portable_platform.h into ngs-special-functions/inc
Then I was able to build this module successfully. But I think there is a cleaner solution... :-)

edit: I was assuming that mpi.h was being included directly by this code, but looking at the source it doesn't appear so. You can close this issue -- I think the issue is with my compilation environment and has nothing to do directly with this code.
