Hi,
It sounds like either a problem with your source code or a problem with
the compiler. You are using the correct flag and a sufficiently recent
version of g++. So it should work.
I'd suggest writing a really simple OpenMP program and checking that it
runs in parallel. I'd also suggest using Solaris Studio ( the flags -O
-xopenmp -xloopinfo -xvpara will give you a bunch of diagnostics) on the
simple test to check whether there's an issue with the source, and
confirm that it is working as expected.
Regards,
Darryl.

Hi,
I have been compiling and running OpenMP parallel programs successfully so far on my
OpenSolaris.2009.10 machine. However I am unable to run one program with more than one
thread(lwp). Please see details of the program below. Please let me know if there is
anything wrong with the compilation or running this particular program. I am using the
following command line arguments to run the program and I am using g++-4.2.3 to compile
the program with "-fopenmp" option and also linked libmtsk.so.1. There are no
compilation warnings/errors.
$env OMP_NUM_THREADS=8<myprogram>
$ ldd<myprogram>
libmtsk.so.1 => /lib/libmtsk.so.1

libgomp.so.1 => /usr/lib/libgomp.so.1
