 | Hi. I am familiar with the following C graphics libraries: Cairo, SDL, SDL2, and OpenGL. The problem I have found with these is that they either require shared libraries (Cairo/SDL/SDL2) or are difficult to make cross-platform (OpenGL). I am wondering if there are any graphics libraries for C that do …  |
