Well, that's not good at all. execvpe() is the basic workhorse of GNU Make: it's the system call that lets make invoke other programs (like compilers etc.) which is pretty much the entire point of running make. However, according to the online docs I found, this function should be available on zOS; for example: https://www.ibm.com/docs/en/zos/2.4.0?topic=functions-exec So, maybe the problem is you need some extra linker flags, or maybe this version of clang doesn't work correctly, or ... something? Unfortunately I have reached the end of my ability to help debug zOS issues. Is there a zOS specific user forum that might be able to guide you? I think that's the help you need, not GNU Make help (per se).
