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.
