I do not know of any one has done or needed this : I run Python under Cygwin. The standard Cygwin thread support doesn't provide the features necessary to compile Python with thread support. Yesterday, when trying to build the Jabber server, I stumbled upon GNU Pth (the portable thread library). This compiles out of the box under Cygwin, and configuring with --enable-pthread gives pthread support. I install this with the standard prefix /usr/local. Configuring Python 1.5.2 with thread support is easy, in Modules/Setup thread, modify the line 'thread' to thread threadmodule.c -lpthread -lpth Then 'make' Python. The library passes the regression tests. Jurgen -- Want to unsubscribe from this list? Send a message to [EMAIL PROTECTED]
