nrn6.0 mpi compiling problem

[neurite]

I've been trying to compile nrn-6.0 with mpi, and I've read the other thread about the issue. But the problem I encountered is a little different.

Code: Select all

./configure --prefix=`pwd` --with-mpi MPICXX=/usr/bin/mpic++ MPICC=/usr/bin/mpicc

works fine, but when I run make, the following error occurs:

-bash-3.00$ ls -l /usr/bin/mpicc

why is make saying that the mpicc directory is not present? It clearly is. How do I get make to compile correctly? I'm using mpi v1.2. Any help would be much appreciated.

Change mpispike.c according to:

I'll update the distribution at the end of
next week.

Awesome, great work Michael, it compiles fine now.
