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"

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!

Yes, probbblems...

Yes.. problems indeed...

I just started writing makefiles this weekend so I am quite new to it. Single file ones are not to hard but things got unruly quite quickly.

You have to turn on the option that display every command, with macros interpreted. With nmake, this option is /D
