Subject: Re: [hwloc-users] hwloc - Build problem.

Hello Anatoly,

You likely need to add libxml2.a to your link command-line. And some
others may be missing later.

Instead of linking with src/.libs/libhwloc.a, you should run "make
install" and use libhwloc.a from there (use
--prefix=</where/you/want/to/install> to tell configure where to install).

Once hwloc is installed, pkg-config can tell you which dependency libs
are needed for static linking:
$ pkg-config --static --libs hwloc
-lhwloc -lxml2 -lz -lm -lpci
If you don't install hwloc in prefix=/usr, you may need PKG_CONFIG_PATH
to tell pkg-config where to look.

Anyway, the above list (-lxml2 -lz -lm -lpci) should be correct.

Brice
