The results of the native sdl-config are only valid for native builds. They are useless for cross builds.No, when you cross compile sdl, you still end up with an sdl-config binary. The solution is to install the binary to a different path and use PATH when building. Where did you get your cross build of SDL from? I assume whoever packaged it renamed the binary but it's not what sdl actually does.The PATH solution works (I used it, too), but it is bad: you have to use a modified PATH for every cross build (make calls configure when the configure script is updated).
Yes, this annoys me too. One thing I thought about is that we could record important environment variables for use when re-running make. It's not just PATH. PKG_CONFIG_PATH is also important for running configure. To properly cross compile, you need to set both.
