[Pw_forum] openmp in 4.2.1

[Timothy Cale]

I am trying to use openmp with espresso-4.2.1 with 64-bit ubuntu 10.04 (gcc
et al. 4.4.3), running on an 8 core single processor (i7 930).

4.2.1 runs the test and examples when compiled without modifying
"configure".
After configuring with --enable-openmp, make crashes in pw.x, with a large
number of "undefined reference to", e.g.;
    omp_get_num_threads
    opm_get_thread_number
    GOMP_parallel_start
    GOMP_parallel_end
among many others.

It looks like there are issues with several functions in libpw.a,
../Modules/libqemod.a, and ../flib/flib.a.

I am new to openmp, but I think I have installed the required libraries
(even 32 bit), and used LIBDIRS with configure.
I successfully ran openmp demos using simple programs.

Any suggestions as to where I might be going astray will be appreciated.

Thanks,
Tim
