Someone realized then that GCC uses the option to generate dependency files and added "-J directory" as replacement for "-M". (See gfortran documentation.) "-M directory" is currently still supported but depreciated. Support for writing the depending information (with -M) is planed for the near future (next few months, i.e. 4.4.0) and the first patches leading to this have already been posted. Thus the answer is: No, currently, gfortran (up to the current developer version) cannot generate the dependency information, but in a few months gfortran 4.4.0 might support it. Tobias PS: This is tracked in http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31588; ignore that there last comment was quite some time ago, it is really been worked on. At the moment the task is to better support the C preprocessor (cpp), which is needed to fix some feature requests/"bugs" but also to support "#include" for the make-file dependency generation. See for instance the following, 12 hours old patch, which is currently still unreviewed and mentions your -M with explicitly as TODO item: http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01753.html PPS: g95 supports the generation of makefile dependency information; you could use g95 as work around until gfortran has implemented it.
