Pyrex Compile - Missing Symbols in Python

Adam McCarthy

I'm trying to get a cross compiler working for arm-wince-pe. This is
the output for the primes Pyrex example. If I compile simple Hello,
World's etc, it works fine, but for some reason Python
libraries/headers seem to produce this. I have libpython2.3.a in
/usr/local/lib/gcc-lib/arm-wince-pe/3.3.3/../../../../arm-wince-pe/lib/
and /usr/lib/python2.3/config. I've checked it using
arm-wince-pe-objdump. I also extracted it with
arm-wince-pe-ar and it contains the symbols.

Below the following output, I've also pasted a debug output from the linker.

Any ideas?
