SDL vs SFML using C when portability matters most? [closed]

Question

I have been doing a lot of reading on SDL and SFML, and no doubt have missed some information or am not understanding it. Here is what I have gleaned:

• SDL is presently the standard (most popular)
• SDL uses C and software rendering (which is slow?)
• SDL embeds on everything?

• SFML is becoming more popular
• SFML uses C++ (but has C bindings) and utilizes hardware accelerated rendering (fast)
• SFML won't embed on everything?

I have to use C and OpenGL for what I want to do. I also need to make sure that the program is as portable as possible. It cannot be slow however.

What should I do?

Answer 1

When using OpenGl with SDL, rendering is done by the hardware, not in software. I never tried SFML, but SDL is very simple and it is a mature library. Having wrote some OpenGl with SDL, the only problem I faced is that it is not possible to have multiple windows with SDL. Regarding portability, my program worked on Linux, MacOS and Windows. For the moment, I don't have any reason to switch to another library.
