... and there are many others in other files. I have realised that in order for warnings to be useful, it is no good for them just to scroll past and then be lost until after the next "make clean". At work, I capture the compiler output for each file and then display all the warnings and errors at the end of the build. Not just those from the files that were compiled during the last run of "make", but for all source files. I don't want to force everyone to see the warnings if they don't want to, but I think we should provide a set-up that makes it easy to do so. Three things are needed: 1. Enable warnings. e.g. GCCFLAGS="-g -O1 -Wall -pedantic -Wpointer-arith" CFLAGS="$GCCFLAGS" CXXFLAGS="$GCCFLAGS" ./configure 2. Save the error output for each C file as (e.g.) ".deps/*.err". E.g. in each Makefile.in: %.o: %.cxx @echo '$(CXXCOMPILE) -c $<'; \ - $(CXXCOMPILE) -Wp,-MD,.deps/$(*F).pp -c $< 2> .deps/$(*F).err + $(CXXCOMPILE) -Wp,-MD,.deps/$(*F).pp -c $< 2> .deps/$(*F).err @-cp .deps/$(*F).pp .deps/$(*F).P; \ tr ' ' '\012' < .deps/$(*F).pp \ | sed -e 's/^\\$$//' -e '/^$$/ d' -e '/:$$/ d' -e 's/$$/ :/' \ >> .deps/$(*F).P; \ - rm .deps/$(*F).pp + rm .deps/$(*F).pp; \ + cat .deps/$(*F).err 3. Display the results (when?). e.g. find . -type d -name .deps -exec cat {}/*.err \; So, can anyone suggest good ways of doing each of these steps, especially step 2: how do I get that change into every Makefile.in, or what would be a better way? - Julian _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
