Hi, It's probably in plain sight somewhere and I missed it, but is there a minimum version of hcoll needed to build 1.10.1?
We have 2.0.0, which allows us to build 1.10.0, but 1.10.1 fails with missing entries in the hcoll_collectives_t structure: CC coll_hcoll_module.lo ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c: In function 'mca_coll_hcoll_mem_release_cb': ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c:60: warning: implicit declaration of function 'hcoll_mem_unmap' ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c: In function 'hcoll_comm_attr_del_fn': ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c:166: warning: implicit declaration of function 'hcoll_group_destroy_notify' ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c: In function 'mca_coll_hcoll_comm_query': ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c:263: warning: implicit declaration of function 'hcoll_check_mem_release_cb_needed' ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c:317: error: 'hcoll_collectives_t' has no member named 'coll_alltoallv' ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c:318: error: 'hcoll_collectives_t' has no member named 'coll_gatherv' ../../../../../../../../ompi/mca/coll/hcoll/coll_hcoll_module.c:324: error: 'hcoll_collectives_t' has no member named 'coll_igatherv' It looks like PR567 in the 1.10 branch that added the new references. Cheers, Ben
