Hi, In ompi/mca/io/romio/romio/adio/Makefile.am there is an entry missing for PVFS2.
Index: Makefile.am =================================================================== --- Makefile.am (revision 9851) +++ Makefile.am (working copy) @@ -139,7 +139,7 @@ libadio_la_LIBADD = \ common/libadio_common.la \ $(HFS_LIB) $(NFS_LIB) $(NTFS_LIB) $(PFS_LIB) $(PIOFS_LIB) \ - $(PVFS_LIB) $(SFS_LIB) $(TESTFS_LIB) $(UFS_LIB) $(XFS_LIB) + $(PVFS_LIB) $(PVFS2_LIB) $(SFS_LIB) $(TESTFS_LIB) $(UFS_LIB) $(XFS_LIB) libadio_la_DEPENDENCIES = \ $(libadio_la_LIBADD) Greetings, Dries PS. This should be the last one, I finally have the combo Open MPI, ROMIO & PVFS2 over native IB up and running :-) Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
