Try the following configure command, by adding the PVFS2 include path to CPPFLAGS, library path to LDFLAGS and -lpvfs2 to LIBS. ./configure --prefix=/path/to/install \ --enable-romio \ --with-file-system=ufs+pvfs2 \ CPPFLAGS="-I/opt/orangefs/include" \ LDFLAGS="-L/opt/orangefs/lib" \ LIBS="-lpvfs2" Wei-keng On Nov 14, 2017, at 9:16 PM, Weihao Liang wrote:

Thank you. I have tried the LD_LIBRARY_PATH way and adding "-L/opt/orangefs/lib -lpvfs2" to the link command line but the errors still happen. So i think maybe still is there something wrong when i built the MPICH?

Hi, all

I have a question is that how to configure mpich-3.2.1 with orangefs- 2.9 (pvfs2)? I just want to enable the MPI-IO ability when running MPI program on pvfs2 filesystem.

The process is still the same it has always been. OrangeFS is a rebranding of what we used to call PVFS v2 :

Configure MPICH with the `--with-file-system=pvfs2` flag.

If you want to configure other file systems, add them with '+':

`configure --prefix=/usr/local/whatever --with-file-system=pvfs2+ufs`
