| In file included from /usr/include/hdf5.h:24:0, | from conftest.cpp:57: | /usr/include/H5public.h:57:20: fatal error: mpi.h: No such file or directory | compilation terminated. It seems to me that not finding mpi.h, which is installed in the system, is not a problem of mathgl source but a problem of source or packaging (?) of hdf5. Do you agree? Dimitris
