We just upgraded to hwloc-1.4.2. We'd like to push upstream some
patches that we maintain, if you find them appropriate.
Here's what we currently maintain:
There are three pieces in this patch that we want to point out:
1. The patch to Makefile.am is an ugly hack to get "make dist" working
in hydra. Specifically, autogen.sh was having trouble running in the
tarball created by "make dist", since it still expects the utils, tests,
and doc directories to be available, but they are never included in the
embedded builds. This is definitely *not* something you should include
upstream, so please only consider this as a bug report instead. What
are other packages using hwloc in embedded mode doing?
2. Within config/hwloc.m4, we moved AC_USE_SYSTEM_EXTENSIONS above as
AC_REQUIRE(AC_USE_SYSTEM_EXTENSIONS). This is cleaner for the cases
where a higher-level configure (for embedded builds) does an
AC_USE_SYSTEM_EXTENSIONS as well. For standalone builds, this should
not cause any issues, but I haven't tested it.
3. In src/topology-xml.c, the additional (char *) is to squash a
compiler warning, since state.tagname is a char *, while "topology" is a
const char *.
