Imagine the following Makefile: ***********BEGIN all: 1.a
1.a: 1.o cat 1.o >> 1.a 1.o: 1.c cat 1.c >> 1.o ***********END Then, if I have file "1.c", this is what happens: [EMAIL PROTECTED]:~$ make cat 1.c >> 1.o cat 1.o >> 1.a [EMAIL PROTECTED]:~$ ls 1.a 1.c 1.o Makefile Nothing new up to this point. If I now delete "1.o" and type "make" again, this is what happens: [EMAIL PROTECTED]:~$ rm 1.o [EMAIL PROTECTED]:~$ make cat 1.c >> 1.o cat 1.o >> 1.a That is, everything is rebuilt. However I don't want everything to be rebuilt. Even if the intermediate "1.o" file has changed, the final result is going to be the same one. Is there anyway I can tell gmake about this ? The idea is to keep ".a" libraries in the CVS together with the source code (but NOT the object files also) and only compile source files when at least one of them is newer than the CVS library. Thanks !!
