Building Dynamic Library for a complex project using makefiles on Linux

I'm trying to build a shared library on Linux having different modules, and since source files are spreded in different sub directories, I am having trouble figuring out how to create scripts and makefiles to compile the whole project as a s开发者_C百科ingle Dynamic shared Library with modules depending on other modules.

Could anyone please give me any examples or tutorials to help me ?

I always found this article useful:

Static, Shared Dynamic and Loadable Linux Libraries

From there you'll want to do a tutorial on Make.
