I'm trying to get Squeak running on my HP Jornada 820. I've used an ancient 3.3 VM until now under Windows CE, but I'd like to get it running under Linux to see if I can improve performance a bit, especially with BitBLT which I know can perform a lot faster on this hardware.
I've learned one lesson: embedded programming requires patience. Everything is slow.
So far I have:
- Gotten Linux (2.4) running on the Jornada from a CF card. This was the easy part.
- Installed Debian Sarge (3.3) from the dusty archives of yore. You see, it needs to support the aforementioned 2.4 kernel.
- Gotten GCC working, which needs a swap space on the CF card. I can hear it screaming in pain! "Hello, world!\n" works.
- Nearly managed to get Squeak to compile. It failed on the Rome plug-in, which was internal.
- Stripped Squeak of all plugins and discovered an unnecessary dependency on a Balloon 3D plugin. It's easy to fix, but I have better things to do.
- Decided that I couldn't cause any more suffering on my CF card and now I'm setting up a Scratchbox environment for cross-compilation.
Currently, I'm stuck on the executables from the cross-compilation environment. GCC on the Jornada makes ELF binaries for "GNU/Linux 2.2" that run fine, but the cross-compiler makes ELF executables with no such versioning... which don't run. Google will inform me.
