Hi! I think I found a bug in gnu make.
When I do a "% make clean && make" I get errors which don't occur when I do a "% make clean; make". I once got a error message saying something like "make internal: got 5 jobs, but only 4 are allowed", but I cannot reproduce that error message again. You have to set some environment variables to reproduce the result: export MAKEFLAGS="-j 4 -l 2.5" export machtype="Linux" (or "MacOS" or "Arm". These three values are recognised.) export DEBUG="true" The error does not occur, if I unset MAKEFLAGS. Then the result of "% make clean && make" is the same as "% make clean; make". The code can be found on GitHub: https://github.com/jedamus/split Please take a look at my Makefile, as it is rather complex. If you have any questions, email them to me. Greetings Leander Jedamus
