First, thanks to all who answered my questions about trying to use a large library with CTypes and my own shared library. The bottom line seems to be this: There is no way to incorporate code external to your own shared library. You have to either pull out the code you want from the static library's source (painful) or you must just include the whole library (huge!) and make it all one big shared library. Did I get that right? If so, it's a sad statement that makes shared libraries harder to write and works against the reuse of older established code bases. I am not criticizing CTypes. This appears to be the way static and shared libraries work, especially on Mac OS X, maybe elsewhere. I'd really like to be wrong about this and I will follow up on some of the suggested reading you all gave me. Thanks, again. -- Lou Pecora, my views are my own. ____________________________________________________________________________________ Looking for last minute shopping deals?
