fail to compile meep becaause of --with-mpi

[longlong10086]

I tried to install meep1.22.0 with source code ,and I got an error .

• error
  checking for mpic++... /opt/meep/meep.deps/bin/mpicc++
  checking for MPI_Init... no
  checking for MPI_Init in -lmpi... no
  checking for MPI_Init in -lmpich... no
  configure: error: could not find mpi library for --with-mpi

How to fix the problem.Hope to get your help.

Your MPI installation is broken if mpic++ doesn't automatically link a library with MPI_Init.

You can look in the config.log file (search for MPI_Init) to find the exact compiler error message.

Is mpicc++ stored in /opt/meep/meep.deps/bin/ ? It is quite unusual location.

This is how variables are defined in my file bashrc file (currently being used on an Ununtu computer but previosly used on a Centos 7 computer too):

LDFLAGS="-L/usr/local/lib -lm" export LDFLAGS
CPPFLAGS="-I/usr/local/include" export CPPFLAGS
PATH="$PATH:/usr/local/bin:/home/user/.local/bin" export PATH
PYTHONPATH="$PYTHONPATH:/usr/local/lib/python3.8/dist-packages:/usr/local/lib/python3.8/site-packages" export PYTHONPATH

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/local/lib64 export LD_LIBRARY_PATH
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH
HDF5_MPI="ON" export HDF5_MPI
