Sorry to keep you busy, but I found another problem with the Open MPI <-> ROMIO integration: mca/io/romio/romio/Makefile.in: # Open MPI: setup the AM_CONDITIONALs to build the different adio devices AM_CONDITIONAL(BUILD_GRIDFTP, [test -n "`echo $FILE_SYSTEM | grep gridftp`"]) AM_CONDITIONAL(BUILD_HFS, [test -n "`echo $FILE_SYSTEM | grep hfs`"]) AM_CONDITIONAL(BUILD_NFS, [test -n "`echo $FILE_SYSTEM | grep nfs`"]) AM_CONDITIONAL(BUILD_PANFS, [test -n "`echo $FILE_SYSTEM | grep panfs`"]) AM_CONDITIONAL(BUILD_PFS, [test -n "`echo $FILE_SYSTEM | grep pfs`"]) AM_CONDITIONAL(BUILD_PIOFS, [test -n "`echo $FILE_SYSTEM | grep piofs`"]) AM_CONDITIONAL(BUILD_PVFS, [test -n "`echo $FILE_SYSTEM | grep pvfs$`"]) AM_CONDITIONAL(BUILD_PVFS2, [test -n "`echo $FILE_SYSTEM | grep pvfs2`"]) AM_CONDITIONAL(BUILD_SFS, [test -n "`echo $FILE_SYSTEM | grep sfs`"]) AM_CONDITIONAL(BUILD_TESTFS, [test -n "`echo $FILE_SYSTEM | grep testfs`"]) AM_CONDITIONAL(BUILD_UFS, [test -n "`echo $FILE_SYSTEM | grep ufs`"]) AM_CONDITIONAL(BUILD_XFS, [test -n "`echo $FILE_SYSTEM | grep xfs`"]) When the ROMIO's configure finds support for a filesystem, it sets file_system_<name> to 1. (This is done by checking support for each of the filesystems listed in $FILE_SYSTEM (passed from --with-filesystems)) In my case, I want PVFS2 so file_system_pvfs2=1 (because configure found all the needed headers) However, two things are wrong with the AM_CONDITIONAL code: 1) FILE_SYSTEM is tested, meaning that if the user demanded pvfs2 but didn't have the headers/tools to build it, ROMIO's configure would have set file_system_pvfs2 to 0, and the code above would still try to build the PVFS2 AD because it only tests if the name was specified. 2) If grep pvfs2 matches, grep pvfs also matches... ;-) Greetings, Dries -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) iD8DBQFEX3+bv/8puanD4GoRAnFbAJ9R0FmSrc/CTrrJ4XX75xOgsafQ8wCgmgq4 IMGFB2OakHVUlPoyugTkoec= =AOJX -----END PGP SIGNATURE----- Disclaimer: http://www.kuleuven.be/cwis/email_disclaimer.htm
