[Pyrex] Problems Building Pyrex Demos On Ubuntu

[Juha S.]

|Hi,

I'm just starting out with Pyrex and I ran into this kind of problem 
with building the demos that come with Pyrex 0.9.6.4. I'm on Ubuntu 7.10 
with Python 2.5, and I get the following output from the terminal for 
trying to build the demos:

:~/Files/Pyrex/Demos$ sudo python Setup.py build_ext --inplace

I think I got a similar output with the gcc build method:
"|bash$ gcc -c -fPIC -I/ /usr/include/python2.5// mymodule.c"

I used "python setup.py install" to install Pyrex, and commands like 
"pyrexc filename.pyx" seem to work correctly.
