Because we have to use RTLD_GLOBAL (since the C extensions aren't linked against libpython), it's not safe to use both the Python 2 & 3 interfaces in the same session of Vim. It looks like the options are either: 1) Only allow one interface to be enabled at a time. 2) Keep track of whether one of the Python interfaces has been initialized and error out if the other one tries to be initialized. I'd personally prefer the latter since that still allows one to build a single Vim binary that supports both Python 2 & 3, but only one of the interfaces can be used per Vim session. -- James GPG Key: 1024D/61326D40 2003-09-02 James Vega <james...@jamessan.com> -- You received this message from the "vim_dev" maillist.
