Hi Jeroen,
Thank you for locating a couple of issues and opening the ticket! I am
about to contact upstream
Replying to [ticket:20136 jdemeyer]:
> 3. meataxe assumes that `char` is `signed char` but that is not
guaranteed by the C standard. This causes breakage on powerpc64le. A work-
around with GCC is `-fsigned-char` but it's better to fix the sources.
OK, but that would also require to either fix the sources (namely the
Makefile), either by using `-fsigned-char` or by passing `CFLAGS`.
> 4. the test-suite has race conditions: testing with `MAKE="make -j48"`
fails while `MAKE="make -j1"` works.
I have seen before that the test suite is flaky. Meataxe's test suite is
about Meataxe executables that read and write data from files. Could file
i/o be the reason for race conditions? Hm. Let's see what upstream has to
say.
