Hi,
additional to the patches used for building on cygwin
openmpi-1.7rc5, a new one is needed for openmpi-1.9a1r27710 build.
See attached for statfs usage.
As config parameters, I added "if-windows,shmem-windows"
to
--enable-mca-no-build=paffinity,installdirs-windows,timer-windows,shmem-sysv,if-windows,shmem-windows
Question 1 :
instead of a platform check should be better to check
if statvfs or statfs are implemented on the platform ?
Question 2:
any specif reason to have reset the shared library
version numbers ?
On openmpi-1.9a1r27710
./usr/bin/cygmpi-0.dll
./usr/bin/cygmpi_cxx-0.dll
./usr/bin/cygmpi_mpifh-0.dll
./usr/bin/cygmpi_usempi-0.dll
./usr/bin/cygopen-pal-0.dll
./usr/bin/cygopen-rte-0.dll
./usr/lib/openmpi/cygompi_dbg_msgq.dll
On openmpi-1.7rc5
./usr/bin/cygmpi-1.dll
./usr/bin/cygmpi_cxx-1.dll
./usr/bin/cygmpi_mpifh-2.dll
./usr/bin/cygmpi_usempi-1.dll
./usr/bin/cygopen-pal-5.dll
./usr/bin/cygopen-rte-5.dll
./usr/lib/openmpi/cygompi_dbg_msgq.dll
Question 3:
there is an alternative way to exclude all the "*-windows" mca
instead of
--enable-mca-no-build=installdirs-windows,timer-windows,if-windows,shmem-windows
Regards
Marco
