Nope. They're shared libraries being built by the distribution itself, as in the case of PyICU, and certain Windows C extensions that need to include the target library (e.g. sqlite) because it's not a "system" library there. It could perhaps be questioned whether it's a good idea to include any other kind of shared library in an extension project, and in fact the common practice to link between Python extensions is to use a Python CObject to wrap an API function pointer table. This neatly bypasses all of the issues... *if* you control the library in question. So far I've done a few experiments with trying to hack LD_LIBRARY_PATH at runtime, use dl.open() with RTLD_GLOBAL, etc. to force finding the right library, but so far it seems like there's no way to get the extensions to consider the opened library to be "the same" as the one they're looking for. (Although it may just be that I'm missing some trick on the build side of the equation.) _______________________________________________ Distutils-SIG maillist - [email protected] http://mail.python.org/mailman/listinfo/distutils-sig
