Dear HWLOC.
I downloaded 1.4.2 version (tar file).
Performed 
1) ./configure --enable-static
2) make
3) Wrote program
#include "hwloc.h"
link with ($hwloc_dir)/src/.libhwloc.a
4) In link stage I get following errors:
Linking  EXE: /space/home/anatol-g/Grape/release_4.6_FH/core/bin/linux64/rhe6/g++4.4.4/debug/mpi_rcv_waitany ...

Attached program file + error report.
I use 
OS: Red Hat 6.0 Santiago  
gcc 4.4.4-13

Can you please help me?
Sorry if my question looks stupid.
Anatoly.
