--- Comment #16 from cgd at google dot com 2010-02-07 21:24 --- (In reply to comment #15) *** Bug 42921 has been marked as a duplicate of this bug. *** FWIW, I actually think that's a different issue (though certainly related). this bug was all about -MD and -MMD -- and what happens when an object file needs to be output, but cannot be because of a missing include. AFAICT, that bug is all about, what should the handling of -MM be vs. missing system headers. That having been said, I will note that with: gcc version 3.4.4 (cygming special, gdc 0.12, using dmd 0.125) you get the results: [...@laptop tmp]$ echo #include does_not_exist.h foo.c [...@laptop tmp]$ gcc -MM -MF foo.d foo.c echo succeeded || echo failed foo.c:1:28: does_not_exist.h: No such file or directory failed [...@laptop tmp]$ echo '#include does_not_exist.h' foo.c [...@laptop tmp]$ gcc -MM -MF foo.d foo.c echo succeeded || echo failed foo.c:1:28: does_not_exist.h: No such file or directory failed So this certainly used to behave as the submitter of 42921 expected at *some* point. As of 4.2.2 (the next version I have handy after 3.4.4) the first case reported succeeded (and the second failed). --cgd -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28435

--- Comment #12 from cgd at gcc dot gnu dot org 2009-09-20 01:57 --- (In reply to comment #11) Gack, sorry, looks like I screwed this up. When I retested after updating, I only compared test results before/after, and saw what I was expecting, I didn't actually recheck all of the output from the new tests. Actually, it looking at this error further, I can't see how the new tests ever passed in trunk. (I initially wrote this in 4.4.0, where I definitely verified that all of the tests passed... but the 'fatal error' bit was changed in trunk, and so I had to change the tests. And I know that I diffed the test results in trunk, but I can only conclude that I never actually verified that they all passed in trunk. *sigh*) Anyway, testing the fix now (copying the error-checking style from the current missing-header-1 test). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28435

--- Comment #6 from tromey at gcc dot gnu dot org 2008-05-09 23:02 --- I think we should give an error by default, and only *not* give an error if -MG is passed. My reasoning is that -MG exists only to disable this error. I couldn't think of a reason to disable it in other cases. For instance, it seems to me that gcc -E should fail if a header is missing. I looked at open_file_failed, but I don't understand the reasoning behind a lot of the logic in there (though see PR 15220). A comment says: /* If we are outputting dependencies but not for this file then don't error because we can still produce correct output. */ ... but this seems to be based on incorrect logic to me. A include may define something which affects later inclusions. I wonder if anybody relies on the current, bogus, behavior. -- tromey at gcc dot gnu dot org changed: What|Removed |Added CC||tromey at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28435

--- Comment #5 from matz at gcc dot gnu dot org 2006-10-18 14:04 --- The problem is in libcpp/files.c:open_file_failed. It deliberately only gives a warning when producing dependencies (and under some circumstances doesn't even give a warning) for missing files. I think it does that under the assumption that the user gave only -M (with -E implied), so he would be interested in the preprocessor output nevertheless, and that can be produced even with missing deps. The problem is, that giving -MD or -MMD does not imply -E, i.e. the user really wants the deps to just be a side-effect, as documented. Probably libcpp needs another option which can be set from the driver, which would make it produce errors instead of warnings. -- matz at gcc dot gnu dot org changed: What|Removed |Added CC||matz at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28435
