What's your compile line and how do you use package config?
Are you building with --static without passing --static to pkg-config?
@HWLOC_LIBS@ should only be needed for static linking so putting it in Libs.private should be fine (it's returned by "pkg-config --libs --static hwloc").

No, this did not actually work. I was confused. It seems that Libs.private is ignored.

Instead, I am now applying the following patch:

--- hwloc-1.6.orig/hwloc.pc.in 2012-11-12 06:33:14.000000000 -0500
+++ hwloc-1.6/hwloc.pc.in 2013-01-04 10:09:54.000000000 -0500
@@ -9,4 +9,4 @@
 Requires.private: @HWLOC_REQUIRES@
 Cflags: -I${includedir}
-Libs: -L${libdir} -lhwloc
+Libs: -L${libdir} -lhwloc @HWLOC_LIBS@
 Libs.private: @LIBS@

This seems to work.

Yes, this did the trick. Thanks!

Hello Erik
I am not a pkgconfig expert but my feeling is that this has buggy for a long time. hwloc.pc.in should likely use HWLOC_LIBS instead of LIBS. On my machine, it makes Libs.private change from -dl to -lm -lnuma here (with -lpci -lxml2 depending on the config). We also need to check whether -ldl should be kept because of plugin support too.
Can you change LIBS instead HWLOC_LIBS in hwloc.pc.in, rerun configure, and try again?

I just installed hwloc 1.6 on a Linux Red Hat system. libnuma is required for linking -- I receive linker errors if I omit -lnuma, and I see that -lnuma is listed in libhwloc.la under "dependency_libs". However, pkgconfig/hwloc.pc does not mention libnuma. It does mention libpci, though.

Does this sound like an error when hwloc.pc is generated, or am I misunderstanding how pkg-config works? If you give me a pointer, I'd be happy to try an provide a patch.
