Reading <http://gcc.gnu.org/news/dependencies.html>, I find that dependency files should be created along the lines of
%.o: %.c ... In gcc version 4.4.4 (Slackware64 Linux version 13.0), I execute the following commands: touch a.c gcc -c -MMD -MP -MF"a.d" -MT"a.d" -o "a.o" "a.c" cat a.c and get the following output: a.d a.o: a.c which is precisely what I want. However, I have a cross compiler using gcc version 4.7.3 which produces the following output using the same commands (obviously, with gcc replace with <path to >/bin/gcc: a.d: a.c I have been looking for the reason for the change, but am unable to find the rational. Please advise whether this is a bug, or if this is meant to be the way gcc will work for all future releases. As I see it, this complicates my Makefile(s) as I have two gcc version that behave differently. This implies that my Makefile(s) will now require a section specifically dedicated to the .d file generation. Whereas I remember that this used to be the way I had to construct the dependency list, this was cumbersome and the way e.g. 4.4.4 supported automatic dependency generation is preferable to me. Thank you for your time, Andy
