Subject: Re: [OMPI devel] Trunk fails to build with --disable-dlopen

Looks like you are correct. The function that calls the rml code is
mca_common_sm_init which is no longer called by anything (other than
mca_common_sm_init_group.. which isn't called either). Let me see if I
can fix this. I need this build working again with --disable-dlopen.

mu-fey:/usr/projects/hpctools/hjelmn/ompi-trunk-git hjelmn$ find opal -name \*.[ch] | xargs grep mca_common_sm_init
opal/mca/common/sm/common_sm.c:mca_common_sm_init(opal_proc_t **procs,
opal/mca/common/sm/common_sm.c:mca_common_sm_init_group(ompi_group_t *group,
opal/mca/common/sm/common_sm.c: /* let mca_common_sm_init take care of the rest ... */
opal/mca/common/sm/common_sm.c: ret = mca_common_sm_init(procs, group_size, size, file_name,
opal/mca/common/sm/common_sm.h:mca_common_sm_init(opal_proc_t **procs,
opal/mca/common/sm/common_sm.h:mca_common_sm_init_group(ompi_group_t *group,
