Follow-up Comment #5, bug #18617 (project make): I would like to draw the attention of everyone in this thread to
http://bashdb.sourceforge.net/remake/ "Remake - GNU Make with comprehensible tracing and a debugger" I find it an invaluable enhancement to make when debugging complex makefiles full of generated code. Give it a try: you won't look back once you've discovered how much easier life is when you can single-step through the source of a makefile, set breakpoints, inspect variables and see the return values from called functions. Stefano: "It doesn't tell which the implicit rule is", are you sure? The trace shows > Trying implicit prerequisite `assert.cxx'. > Found an implicit rule for > `/home/stefano/src/reilabs/flash2sip/contrib/src/ptlib_2.2.1/lib/obj_linux_x86_r/assert.o'. Therefore the implicit rule it is referring to must be of the form %.o: %.cxx mustn't it? _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?18617> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/ _______________________________________________ Bug-make mailing list Bug-make@gnu.org http://lists.gnu.org/mailman/listinfo/bug-make
