Cross-compiling SDL 1.2 for BBB.

Hi,

I’ve been trying to setup my cross-compile tool chain for programming on the BBB through a Linux Mint box with Eclipse running in VMPlayer. So far I’ve been able to configure almost all the needed components properly to cross-compile and deploy using g+±4.8-arm-linux-gnueabihf (for some reason the non ‘hf’ version doesn’t work-- I admit I am still trying to differentiate between the various flavors of arm out there that are represented by the compilers).

However, I can’t seem to quite get/find a cross-complied version of the SDL lib (I know SDL2) doesn’t work on the BBB.

I found this page with some instructions, but it doesn’t seem to work quite right for me either. Further, I know there is a version of SDL 1.2 that can be apt-get from the BBB itself-- but of course this doesn’t help when wanting to try to cross-compile rather than compile directly on the BBB.

Lastly, though I’ve been able to find some rather easy/straight forward instructions for the Raspberry Pi, I can’t seem to find anything comparable for the Debian version of BB.

Does anyone happen to have any recommendations or suggestions?

Thanks-

Just build natively on the BBB.

‘hf’ signifies hardware floating point, which the Beagle has.

I build SDL1.2 natively on the BBB for BeagleSNES. I use the framebuffer for video, ALSA audio, and the joystick subsystem without any issue. I have not tried the X11 video target because I have only worked with the framebuffer, but there isn’t a reason why it would not work just as well.

There is currently no framebuffer target in 2.0. I have added a rudimentary BeagleBone Black video target to my 2.0 codebase as I continue to work on getting the kinks worked out of the SGX-based OpenGL ES on the framebuffer with the 3.17 kernel. With the features of the BBB still in flux, I would stick with 1.2 for your development for now.

Disable as much of SDL as you can via the configure script when you build natively. I don’t remember having to enable swap to build SDL, though I definitely have to enable it to build BeagleSNES natively. I had to pull in a few dev packages to get the headers that I needed to build SDL, but it has been so long since I have done it that I don’t remember which ones.

Take a look at the sdl package for OpenEmbedded, it's always a good
place to reference for cross compiling quirks.
