Audio / How exactly are libopenal32 and libsndfile linked in static SFML (Windows)?
« on: July 03, 2012, 04:01:02 pm »
Hi, as I would prefer to release the library I'm currently working on as DLL-free as possible, I've been trying to compile OpenAL-Soft and libsndfile statically using MinGW/MSYS with gcc 4.7.0 on Windows 7 x64. This has proven to be rather tricky, but that will possibly be the subject of another (future) thread.
As my library is GPL3, the license would not be a problem.
What I'm concerned with right now, however, is how when statically building SFML with CMake on Windows it apparently (looking at Macros.cmake and generated build files) links to libopenal32.a and libsndfile.a just like the other external libraries, appending them to libsfml-audio-s.a. However, when using the audio module in a derivate project, it still requires the DLLs to run.
How is this accomplished? Are the static libraries just wrappers for the DLLs? And is there a way to use the provided libraries statically instead, without having to go through the trouble of building them myself?
Thanks for your help. I apologize if I assumed anything wrongly about the linking process.
Also, if anyone could direct me to a more suitable place for learning how to build either OpenAL-Soft or libsndfile with MinGW, or asking about these, I would be grateful.
