C++ module - sr-users

11 Jan 2017

I added a C++ module to kamalio at some point, and now I am trying to
integrate that module with another C++ internal library, but I'm getting
all sorts of headaches when trying to compile.

The latest problem is during the "make install" part of the build - it
seems like the objects from the module are "infecting" the link line of the
internal library it's dependent on.

Here is the Makefile for the module. At the time, the only way I figured to
link in the C++ object was adding them to the LIBS. Now, i think this
interferes with the 'make install' dependencies.

Any thoughs on how to do this properly would be great!

Thanks
