Makefile Troubbles

I have a not to complex project that I wish to set up makefiles for. I have got the project to successfully compile by dumping all the object into one directory and then linking all said objects. Verified to work correctly.

I now wish to convert half the project into a library as it is an API and I do not need source access to it. I built a second makefile in the library directory and call it with the root makefile however none of the source files compile in the library directory and now I have random errors on all "make xyz"

The project layout:

My Problems Are:

1- None of the source files in the ./lib/ directories will compile. I know the rule works as if I replace %.o : %.c with an actual name it knows that folder to go to and compile that object. However the ./prj/Makefile has a very similar rule and it works correctly. Does the fact they are all in different folders make a difference??

2- When I run any command even clean I get "Creating library ..." and the ./lib/Makefile never executes its clean routine. If i run "make clean" from within that ./lib/ directory it works perfectly fine.

3- The startup routine is always compiled, regardless of weather it is up to date.


Can anybody lend a hand? I have read the GNU 'make' documentation and read tutorials but they are all for extremely simple projects and none deal with macros and multi folder compiling.

Thanks!
