Hi,
when you invoke x10c++ with -gpt, it automatically adds the
-lprofiler argument to the g++ command it generates under the covers. If
libprofiler.so is in a standard place (eg /usr/lib) then there is nothing
else to do.
If you have gperf tools installed somewhere else, then you will need
to fiddle with the g++ command. The easiest way to experiment with this is
to get x10c++ to print the g++ command it is using, and then manually
adjust that until you get something that works.
[dgrove@linchen myTests]$ x10c++ -gpt -report postcompile=5 HelloWorld.x10
