I have a project organized as this: ================================ Top level directory sources: top1.c top2.c top3.c ...... 2nd level directory sources: second1.c second2.c ..... ================================
My makefile looks like this: ================================ all: target1 target2 target1: depend command1 target2: command2 ..... ================================ Now, I want simply build "target2", so I issue a command like this: ================================ $ make target2 ================================ I expect "command2" to be run directly since there is no dependencies for "target2", however, GNU make always compile my top level sources before executing "command2". I am sure command2 is only to compile sources in 2nd level directory, and it has nothing to do with sources in top level directory (top1.c top2.c ....). I just wonder why GNU make always compile top level sources? and how to avoid this and simply executing "command2"? Any suggestion?? Thanks! Kevin
