Creating libraries?

[Mathiasdm]

I'm trying to find out more about writing libraries for usage by programs (both statical and dynamical ones). I've been looking around on google for a while, but it's a mess! I can't seem to find a clear explanation on writing libraries (I'm working in C and C++, by the way).

Could anyone point me to a nice link?

Look for the command "ar"
It's actually pretty simple (just compile some object files and pass them to ar)

For loading dynamic libraries, the "dlfcn.h" (link to it with "-ldl")
For compiling dynamic libraries (shared objects) use the "-fPIC" and "-shared" flags when generating the object files.
