Can you please elaborate on what makes a non-header-only library so very problematic?
Its probably more a UNIX thing, I'm not sure if windows developers could care one way or another. But on LINUX/UNIX, there is a central repository of pre-built libraries that we syncronize our builds against. Uncecessarily adding new libraries makes the process that much more to manage. It is "so" much easier to not have to bother with that and just have the compiler link in any functions that are used at compile time from the headers. You would be surprised to now how much compiler technology has improved in the last 3-4 years. The old reasons for making libraries are no longer always valid. Compilers are very smart and very fast, and thats how I pefer to code.
