Team, Can any one of you help to resolve this issue. My file structure will have root make file which will call makefiles in each subfolder. Some of the CC files which are dependant on other folder object files are getting recompiled.
For example 1. Folder d1 will have a.o which is compiled from a.cc 2. Folder d2 has b.o which is compiled from b.cc. 3. b.o is dependant on a.o If any changes are done to a.cc file, b.o should get rebuilt. This is not happeneing on LINUX. Please advise. I could see preprocessor directives commands are checking only .h files. Let me know if you need copy of my make files?

I cannot give specific name for .d file. How can I append dependencies when we have multiple levels of compiling?

Actually, you should get a "command not found" here from the shell, since -include is not a legal shell command. You must have added this line AFTER you built a.o, and never cleaned up to run from scratch. You should check out the document on my website for auto-creating prerequisites. Read it carefully and it will work as advertised. If it doesn't work, you're not reading it carefully enough :-). -- ------------------------------------------------------------------------ ------- Paul D.
