I believe I reported this before on a different mailing list, but willrepeat it here. The PGI compilers rely on the Linux kernel for somethings. We found that the ability of the PGI compilers to build OMPI,therefore, was highly dependent upon the specific Linux kernel on themachine.

For example, on one of our clusters, anything less than PGI 7.2-5would not compile OMPI 1.3. The reason was that the Linux kernel onthat machine no longer had a specific function required by OMPI 1.3,so the build system barfed. On other machines with an earlier kernelversion, it built fine with PGI 7.1.

I can look up details next week on that particular error. My pointhere is to simply point out the dependency, so it is little surprisethat someone might be able to build on one machine, and not another.

It's odd because PGI 7.0 and 7.1 compile OMPI just fine (don't knowabout PGI 7.2).

All,
I don't know PGI's compilers, but is it possible that since"restrict"was supposedly introduced as a C99 feature that it is notsupported
   by default by their C compiler?  This would explain the wording of
the error message which indicates interpretation of "restrict"as a
   variable name.
Perhaps, like gcc, there is a -std=c99 option for the PGIcompiler?
        regards,
