I try to package (Linux/c++/rpath) some libs with my app, as I doubt sdl1.2 will be around for very much longer. Now libsdl_image depends on libpng, but all I find are symlinks back and forth libpng12.so.0 etc. and only a libpng12.a but no .so (only symlinks on Ubuntu).
How to link to .a or where to find the .so? Do I need to include that at all? Is it enough if I pack/ship with my app only libsdl_image as there are also other libsdl dependencies like tiff etc. Are those dependencies only needed to compile libsdl?
