Parenthetically to your main question: it turns out to be quite easy to write a Makefile which will fail with -j (or, perhaps better put, I find it often takes at least a little effort to adjust a working Makefile so that it also works with -j). If non-trivial dependencies are incompletely expressed, then a non-j Make run might work by accident, as a consequence of the (consistent) order in which Make serialises the dependency tree. It might work only because an un-expressed dependency is created as a side-effect of an action that happens to be called relatively early. Best wishes, Norman -- Norman Gray : https://nxg.me.uk
