I recently upgraded OMPI's SVN trunk to hwloc 1.4.2, and immediately broke builds on Solaris. After some hunting around, here's what our friends at Oracle have found:
- Building hwloc 1.4.2 standalone on Solaris works fine. - Building OMPI SVN trunk (with hwloc 1.4.2 embedded) on Solaris fails due to a missing -lpicl. - The issue seems to be in hwloc's src/Makefile.am: if HWLOC_HAVE_SOLARIS ldflags += -lpicl endif HWLOC_HAVE_SOLARIS Specifically, -lpicl gets added to standalone builds but not embedded builds. Shouldn't the check for -lpicl be in hwloc.m4 so that it gets added to HWLOC_EMBEDDED_LIBS? See the attached patch. Or is there a deeper reason we didn't use AC_CHECK_LIB and used HWLOC_HAVE_SOLARIS instead? (e.g., is -lpicl Bad on other platforms?) -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
