RE: [photran] OpenMP with Intel Fortran on Photran
|
I appreciate your help. I would be lost if I was on my own.
I have followed your suggestion and collected a couple of screen shots. One shows where I put "-openmp" in the linker settings. The other screen shot shows you the source code and the errors I get.
Thanks, David Bal

I’m not sure what to suggest here. That
works for me and I cannot reproduce what you are seeing. Can you double
check where you added the -openmp property in the linker tool again just to be
sure it is correct? You can send me a screen shot of the property page if
you want and I’ll see if I can spot anything.
If that does not lead us anywhere, can you
zip up the project and send it to me to look at? My reproducing test case
is very simple. I created an Intel Fortran executable project with a
source file that is just a helloworld program. Then I enable –openmp
in the compile step to see the original problem. Then I add –openmp
in the linker tool as described to see the problem resolved. Are you
doing anything more complicated/different than that (multiple source files,
other options set, etc., anything else that might help me reproduce the
situation)?
Thanks,
Bill

I did as you said and added -openmp under Intel
Linker tool > “Command Line” to the “Additional
Options” box. It did not work. I got "error #10236:
File not found: '-openmp'" Any suggestions?

That should work but I just tried and see that it does not.
The –openmp option setting is supposed to be automatically
propagated to the link step when you change it on the compile step.
I’ll investigate why it is not happening but in the meantime, you can
open the property page settings for the Intel Linker tool > “Command
Line” and add the –openmp option to the “Additional
Options” box. That should fix it for now.
Hope that helps,
Bill Hilliard

Subject: [photran] OpenMP with Intel
Fortran on Photran
I
am having trouble using OpenMP with the Intel 11.1 compiler on
Photran. My project is a Executable Intel Fortran project (using
managed make file I believe).
In order to turn on OpenMP I went under project properties then Intel IA-32
Fortran Compiler then Language. I changed the Process OpenMP
Directives option from Disable to General Parallel Code (-openmp).
When I compile a very simple OpenMP program I get a string of errors in the
Fortran Linker. The first error is "undefined reference to
`__kmpc_begin'"
My guess is that the managed make file can not handle OpenMP. Is that
right? Any other ideas?
Thanks,
David Bal
