Hello, 1 - I'm trying to compile the latest Zope2 CVS fron today on cygwin. 2 - I've done all is described in ChrisMcD post : http://zope.nipltd.com/public/lists/dev-archive.nsf/0a8715d5f3c7b6a3802568c1... (get python 2.1.1, src, compiel with thread, create a fresh FCNTL.py). 3 - When i do python wo_pcgi.py i get this error. gcc -shared -Wl,--enable-auto-image-base ./zlib.o ./adler32.o ./compress.o ./cr c32.o ./gzio.o ./uncompr.o ./deflate.o ./trees.o ./zutil.o ./inflate.o ./infbloc k.o ./inftrees.o ./infcodes.o ./infutil.o ./inffast.o -L/usr/local/lib/python2. 1/config -lpython2.1 -o ./zlib.dll make: *** No rule to make target `../Components/initgroups/initgroups.c', needed by `initgroups.o'.

Any clue will be more than welcome. When solved, I'll summarize that "Z2 cvs on cygwin" as a how-to. Thanks a lot in advance.
