1See the README.threads in the main perl 5.004_xx development 2distribution (x >= 50) for details of how to build and use this. 3If all else fails, read on. 4 5If your version of patch can't create a file from scratch, then you'll 6need to create an empty thread.h manually first. Perl itself will need 7to be built with -DUSE_THREADS yet. If you're using MIT pthreads or 8another threads package that needs pthread_init() to be called, then 9add -DNEED_PTHREAD_INIT. If you're using a threads library that only 10follows one of the old POSIX drafts, then you'll probably need to add 11-DOLD_PTHREADS_API. I haven't tested -DOLD_PTHREADS_API properly yet 12and I think you may still have to tweak a couple of the mutex calls 13to follow the old API. 14 15This extension is copyright Malcolm Beattie 1995-1997 and is freely 16distributable under your choice of the GNU Public License or the 17Artistic License (see the main perl distribution). 18 19Malcolm Beattie 20mbeattie@sable.ox.ac.uk 21
