Hi guys/madames! I'm no C expert and I'm facing the following problem, solving which is proving a challenge to me, although I guess it's trivial for any little-experienced C programmer. I'm working on Linux. I'm adding some new features to pjsip, which affect pjsua-lib, pjmedia, and possibly other subsystems. I'd like to make an 'addons' directory in pjsip root directory, with the following structure: pjproject-$ver/ | +--addons/ | +--feature1/ | | | +--src/ | +--include/ | +--... | +--feature2/ | | | +--src/ | +--include/ | +--... | ... Now, I have to include those new features in a lot of existing files, so I have to change some Makefiles in order for the compiler to include the addons/featureN/include directories. But I don't know how to do it. My tryings were all unsuccessful. Could anyone please explain me, in a very basic way, the steps I need to take (e.g., the changes in existing Makefiles, the new Makefiles that I have to create, etc.)? I hope that I'm not asking too much and that I'm not going to get too many RTFM answers! ;) Thanks in advance for your kind assistance!
