Building Einstein for the Nokia Internet Tablet on MacOS X

To build Nokia binaries, you need a cross compiler. The previous method was to use the official Maemo SDK (scratchbox compilers) under Linux. The trick was to pass -I and -L options to the compilers or run them inside the scratchbox chroot (but in this case, you need to put Jam in the chroot). I did not find this very convenient, especially considering that I had to run Linux inside VMWare Fusion...

You can now directly build compatible cross compilers with MacPorts.

1. Install MacPorts
2. Install the cross compiler with:

sudo port install arm-none-linux-gnueabi-gcc

3. Get K with cvs and compile it with jam -starget=nokia2006
4. Get Einstein with subversion and compile it with jam -starget=nokia2006 -sK=<path_to_K> -sjittarget=GENERIC

You can find more details about the compilation process in the general BuildInstructions.

Notes

The default JIT Target (ARMLE) doesn't work yet. It compiles, but then Einstein crashes. This is why you have to mention -sjittarget=GENERIC in the command line.

I believe that the Nokia 800 with OS2007 has a different version of libXau. It's now libXau.so.6 instead of libXau.so.0. The above method will compile against libXau.so.0 (which I directly copied from a Nokia 770 with OS2006), and therefore the binary will not run. I would be grateful if someone with a Nokia 800 and OS2007 could check that and possibly fix the problem by either:

1. Create a specific nokia2007 target with the new libXau
2. or try to use -L instead, so that the binary will run on both platforms and dynamically choose the proper binary.
