Hi dr.bennix,

I asked PGI Customer Support to send you an updated cdefs.h and siterc file for Mountain Lion.

I am having the same problem

On October 29, I sent mail to dr.bennix with cdefs.h and siterc files.

I have attached two files that should get around your problem until
we get it fixed in a release.

Replace the /opt/pgi/osx86-64/12.9/include/sys/cdefs.h with
the attached file. It will solve the cdefs.h problem.

Store the attached siterc file as
/opt/pgi/osx86-64/12.9/bin/siterc
to eliminate the ‘vzeroupper’ messages.

I will send them again

I am also having the same problem.

I have that too.

Should this matter be solved by now or is it still the same problem, if so please send me the fixed file as well.

We had to undefined the variable that checks the gcc version.

Download the 13.3 release and pull the cdefs.h file out of there.

Or send mail to trs@pgroup.com and we can send it to you.

Another workaround.
Add –D__GNUC__ to your compile line.
