Hello,
I get the following problem when we compile OpenMPI-2.0.0 (it seems to be
specific to 2.x; the problem did not appear with 1.10.x) with PGI:
CCLD opal_wrapper
../../../opal/.libs/libopen-pal.so: undefined reference to `opal_atomic_sc_64'
../../../opal/.libs/libopen-pal.so: undefined reference to `opal_atomic_ll_64'
../../../opal/.libs/libopen-pal.so: undefined reference to `opal_atomic_swap_64'
make[1]: *** [opal_wrapper] Error 2
It is a little for me to pin point the exact problem but i can see the
following:
$ nm ./.libs/libopen-pal.so | grep atomic

Any idea of how to fix the problem?
Thanks,
