Hello Dave and all,
I tried what you suggested.. but..
I am using both mpi for the x10rt and the gpt library
My command line looks like this:
bin/x10c++ -x10rt mpi PATH_TO_SOURCE -o EXECUTABLE -O -gpt
And this is the error I get.
x10c++: /usr/bin/ld: cannot find -lprofiler
collect2: ld returned 1 exit status
x10c++: Non-zero return code: 1
I am guessing it could be because I have installed gperftools with prefix
and not in the default location(due to limited permissions). From the
compiler's man page I cannot find something to specify the path to gperf
tools.
Finally this is the output from the postcompiler..I cannot really say there
is something wrong..but maybe you could have a look. The -lprofiler flag is
there though(???)
