--- Comment #3 from davidz <dx_zhou at hotmail dot com> 2011-11-29 14:56:41 UTC --- I am a little confused. -MT will create .d file. Then make command will include .d and re-compile if dependency file changes. The issue is that g++ 4.6.1 doesn't re-compile if I touch .h. Does this mean my test.d format is wrong? If I need another -MT, what syntax it should be? Thanks a lot! (In reply to comment #2) > This was an expected change, see > http://gcc.gnu.org/bugzilla/show_bug.cgi?id=12448 . Which says you need > another -MT option to include the .o target.
