Hello Torsten,
unluckily the original patch has disappeared from sourceforge; but since this
question has been popping up at least once a week, I'm posting to the
Foxboard mailing list as well.
Here are the instructions:
- import Axis SDK environment defs (adjust your paths):
cd /home/fox/devboard-R2_01 && . init_env
- create a directory to save the attached files in and move there
- the Makefile target "prepare" downloads Python, applies the patch and
creates the staging directories; it is needed only once, and you invoke it
with "make prepare"
- everything is now ready, so Python compiles like any other program:
make cris-axis-linux-gnu
make clean
make
- a complete Python distribution ends up in /tmp/python_fox; take just what
you need (it's big) and copy it to the Fox (or maybe on a USB key)
CAVEAT: I've never tried compiling with uClibc, so I don't know if it works
or not.
HTH,
Ant9000
