A parallel build of xemacs-21.5.14 fails because some targets try to run the 'ellcc' program before it has been built. Here's a log, showing that the command to build ellcc does run, but that make doesn't wait for that to finish before trying to run ellcc. Suggested fix is to make the commands that require ellcc to be built state this in their dependencies. This could be a little bit tricky because they are often separate makefiles in separate directories. Still, at least adding the dependency will give a slightly earlier failure in the case that ellcc is not built yet. avised＠ftidev1 ~/inst/xemacs-21.5.14 $ make -j -l 1 Producing `src/Emacs.ad.h' from `etc/Emacs.ad'.
