Hello,

to be sure I understand properly the issue: you say that the value of the LIBS from Makefile of the module is inherited when compiling the internal library?

Cheers,
Daniel

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
