I am trying to compile Python 3.2 for ARM920T (4T architecture), but I am getting some strange errors.
I am compiling Python inside a Scratchbox environment, configured to use the following compiler: "gcc version 4.3.3 (Sourcery g ++ Lite 2009q1-203)", which is a crossword compiler.
When compiling, I set the architecture flag -march = armv4t in the following environment variables: CFLAGS, CPPFLAGS, SBOX_EXTRA_COMPILER_FLAGS.
It compiles into scratchbox, and I can run the python interpreter with the armbox emulator.
However, when I move it to my ARM920T, I immediately get an illegal instruction error after running python exe.
A core dump produces the following output:
Program terminated with signal 4, Illegal instruction.
And the first few lines of the back trace:
#0 0x00138810 in __aeabi_dadd ()
#1 0x001134f4 in PyLong_FromString (str=0x402de300 "3644798167", pend=0x0, base=10) at Objects/longobject.c:2001
