You need SDL1, not SDL2.

thanx, but still segment fault.

You can try to build a debug build:

$ mkdir build && cd build
$ cmake .. -DCMAKE_BUILD_TYPE="Debug"
$ make -j$(($(nproc) + 1))

Then attach the GDB debugger to your process (gdb ./axpbox) and if it segfaults, print a backtrace (type bt + ENTER). That would help figuring our where the segfault comes from.
