--- Comment #5 from howarth at bromo dot med.uc.edu --- This is extremely reproducible at r217383 on darwin and no other breakage in the parallel make has been seen this week prior to this commit. The accumulated error messages in the failing build are... make[3]: *** read jobs pipe: No such file or directory. Stop. make[3]: *** Waiting for unfinished jobs.... ... ake[2]: *** [all-recursive] Error 1 make[2]: Leaving directory '/sw/src/fink.build/gcc50-5.0.0-1000/darwin_objdir/x86_64-apple-darwin13.4.0/libjava' Makefile:17122: recipe for target 'all-target-libjava' failed make[1]: *** [all-target-libjava] Error 2 make[1]: Leaving directory '/sw/src/fink.build/gcc50-5.0.0-1000/darwin_objdir' Makefile:20722: recipe for target 'bootstrap' failed make: *** [bootstrap] Error 2 make: INTERNAL: Exiting with 1 jobserver tokens available; should be 16! It looks like the failure occurs when the java classes are being compiled. Can we revert r217383 until the flaw in its handling of the parallel make is resolved? Having to build gcc serially is very painful.
