Do not get fooled by the symlinks to opal_wrapper !
opal_wrapper checks how it is invoked (e.g. check argv[0] in main()) and
the behavior is different
if it is invoked as mpicc, mpiCC, mpifort and other
If the error persists with mpicc, you can manually extract the mpicc
command line, and manually run it with the -showme parameter,
it will show you the full command line (and who knows, mpicc might
invoke a C++ compiler after all, and that would be a config issue)

Sam and Jeff,
Thank you for your answers. My first attempts actually used mpicc
rather than mpiCC, switching to mpiCC was simply to check out if the
problem persisted. I noticed that both mpicc and mpiCC are linked to
the same file (opal_wrapper) and didn't bother switching it back. I'm
not sure if the wrapper figures out what compiler you call because I
was getting the same error message. Jeff is right pointing out that
'try' is reserved but the original file seems to be really old (think
1970). Apparently, the new compiler (shipped with OMPIv4) is more
sensitive and beeps when the older didn't.
Thanks again,
AFernandez
Indeed, you cannot use "try" as a variable name in C++ because it is a
https://en.cppreference.com/w/cpp/keyword.
As already suggested, use a C compiler, or you can replace "try" with
"xtry" or any other non-reserved word.

Hi,
It looks like you are using the C++ wrapper compiler (mpiCC)
instead of the C wrapper compiler (mpicc). Perhaps using mpicc
instead of mpiCC will resolve your issue.
Best,
Sam

Hello,
I'm trying to compile HPL(v2.3) with OpenBLAS and OMPI. The
compilation succeeds when using the old OMPI (v1.10.8) but
fails with OMPI v4.0.0 (I'm still not using v4.0.1). The error
is for an old subroutine that determines machine-specific
arithmetic constants:

I don't understand the nature of the problem or why it works
with the old OMPI version and not with the new. Any help or
pointer would be appreciated.
Thanks.
