11 years ago I was able to build it with "-j8" on my system without running into the problem. Eventually I ran in the section problem the way you did.
The problem with the perl script "gen-upc-ld-script.pl" is that it expects GNU ld, which Mac does not use. I see that for libgupc in GUPC we pass in "--without-gnu-ld" in which case we do not run the script on Mac.

11 years ago I am getting an error:
/bin/sh: /eng/upc/dev/nenad/clang-upc/src/llvm/tools/clang/runtime/libupc/gen-inline-libupc.pl: Permission denied
Like ${PERL_EXECUTABLE} is not defined.

11 years ago Also, note the line:
199 # The link script is always enabled 200 set(HAVE_UPC_LINK_SCRIPT TRUE)
Is this supposed to be conditional on LIBUPC_ENABLE_LINK_SCRIPT?

11 years ago I was wondering if we could use
if (APPLE) or if (CMAKE_HOST_APPLE)
to disable a link script on MacOS, without the need to specify that on the command line.?
On MacOS, I have tried building Clang UPC twice with -j12 (on an 8 HT/4 core system) and it fails the same way.

However, if I run "make -j1", the compiler appears to build properly ... though it does run into problems compiling the libupc runtime (some files are written in .upc) due to pgm_info bug.
