Subject: Re: [OMPI devel] 1.5rc5 has been posted

To follow up on http://www.open-mpi.org/community/lists/devel/2010/08/8417.php: OpenMPI 1.5rc5 fails in opal/tools/wrappers for PGI 10.3.

The problem appears to be a missing -lpthread in the definition of most of the *LIBS variables in OpenMPI 1.5rc5 opal/tools/wrappers/Makefile:

[root@hydra src]# diff openmpi-{1.4.2,1.5rc5}/opal/tools/wrappers/Makefile | grep lutil

< LIBS = -lnsl -lutil  -lpthread

> LIBS = -lnsl  -lutil

< OMPI_WRAPPER_EXTRA_LIBS =   -ldl   -Wl,--export-dynamic -lnsl -lutil -lpthread -ldl

> OMPI_WRAPPER_EXTRA_LIBS =   -ldl   -Wl,--export-dynamic -lnsl -lutil -ldl

< OPAL_WRAPPER_EXTRA_LIBS = -ldl   -Wl,--export-dynamic -lnsl -lutil -lpthread -ldl

> OPAL_WRAPPER_EXTRA_LIBS = -ldl   -Wl,--export-dynamic -lnsl -lutil -ldl

< ORTE_WRAPPER_EXTRA_LIBS =  -ldl   -Wl,--export-dynamic -lnsl -lutil -lpthread -ldl

> ORTE_WRAPPER_EXTRA_LIBS =  -ldl   -Wl,--export-dynamic -lnsl -lutil -ldl

< WRAPPER_EXTRA_LIBS =   -ldl   -Wl,--export-dynamic -lnsl -lutil -lpthread -ldl

> WRAPPER_EXTRA_LIBS = -ldl   -Wl,--export-dynamic -lnsl -lutil -ldl

< crs_blcr_LIBS = -lnsl -lutil  -lpthread

> crs_blcr_LIBS = -lnsl  -lutil -lpthread

[root@hydra src]# diff openmpi-{1.4.2,1.5rc5}/opal/tools/wrappers/Makefile | grep LINK

< LINK = $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \

> LINK = $(LIBTOOL) $(AM_V_lt) --tag=CC $(AM_LIBTOOLFLAGS) \

< $(LINK) $(opal_wrapper_OBJECTS) $(opal_wrapper_LDADD) $(LIBS)

> $(AM_V_CCLD)$(LINK) $(opal_wrapper_OBJECTS) $(opal_wrapper_LDADD) $(LIBS)

I don't know anything about automake, so I don't know what code to look at that changed between 1.4.2 and 1.5rc5 that defines the *LIBS Makefile variables.

We still have one known possible regression:

But we posted rc5 anyway (there's a bunch of stuff that has been pending for a while that is now in).  Please test!
