2016-06-01Yet another Makefile reform : a unique phase without nasty make tricksPierre Letouzey
We're back to a unique build phase (as before e372b72), but without relying on the awkward include-deps-failed-lets-retry feature of make. Since PMP has made grammar/ self-contained, we could now build grammar.cma in a rather straightforward way, no need for a specific sub-call to $(MAKE) for that. The dependencies between files of grammar/ are stated explicitely, since .d files aren't fully available initially. Some Makefile simplifications, for instance remove the CAMLP4DEPS shell horror. Instead, we generalize the use of two different filename extensions : - a .mlp do not need grammar.cma (they are in grammar/ and tools/compat5*.mlp) - a .ml4 is now always preprocessed with grammar.cma (and q_constr.cmo), except coqide_main.ml4 and its specific rule Note that we do not generate .ml4.d anymore (thanks to the .mlp vs. .ml4 dichotomy)
2014-02-27Makefile: re-introduce 2 phases to avoid make strange -include'sPierre Letouzey
Yet another revision of the build system. We avoid relying on the awkward include-which-fails-but-works-finally-after-a-retry feature of gnu make. This was working, but was quite hard to understand. Instead, we reuse the idea of two explicit phases (as in 2007 and its stage{1,2,3}), but in a lighter way. The main Makefile calls Makefile.build twice : - first for building grammar.cma (and q_constr.cmo), with a restricted set of .ml4 to consider (see variables BUILDGRAMMAR and ML4BASEFILES). - then on the true target(s) asked by the user (using the special variable MAKECMDGOALS). In pratice, this should change very little to the concrete developper's life, let me know otherwise. A few more messages of make due to the explicit first sub-call, but no more strange "not ready yet" messages... Btw: we should handle correctly now the parallel compilation of multiple targets (e.g. make -jX foo bar). As reported by Pierre B, this was triggering earlier two separate sub-calls to Makefile.build, one for foo, the other for bar, with possibly nasty interactions in case of parallelism. In addition, some cleanup of Makefile.build, removal of useless :: rules, etc etc.
