You need to import os before you can call it. Try:

...

...

import os os.system('gcc -v')

Also, a simple test to see more debug information is:

...

...

import weave weave.inline("",[],verbose=2)

The output from this may provide a few more hints as to what is happening. Also, weave only works if you have a C++ compiler installed (MSVC++ or gcc). Without one of these, there is no way for weave to compile the code. Eric
