-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Brian Dessent on 3/9/2008 6:23 AM: | Current unreleased Cygwin CVS (which will be 1.7.0 at some point in the | not too distant future) has support for fopencookie() and funopen(), | however this causes building autogen to fail. Autogen seems to be | assuming it's on glibc if these functions are detected.
I implemented newlib's fopencookie (as used in cygwin) after Linux's, except that it is declared solely in <stdio.h> rather than <libio.h>. If the signature and usage doesn't match Linux (other than which header to use), then that is a bug in newlib that should be corrected, and preferably before cygwin 1.7.0 is released. Also, I implemented fmemopen directly in newlib, although cygwin hasn't incorporated it yet (even though it is being standardized by POSIX 200x). ~ Maybe it would be better to get cygwin to incorporate fmemopen, then have autogen use fmemopen directly rather than its wrapper using fopencookie/funopen when the platform has a working fmemopen. | then it detects funopen() and tries to | use that but also fails because its idea of the cookie function | signitures differs from Cygwin/newlib's: This one is a bit different. funopen comes from BSD heritage, but newlib had already changed the signature different that what was present in BSD. ~ Since funopen is not standardized, you will just have to do a configure-time test for what signature it uses, since changing the signature now would break any existing newlib app that relies on the existing funopen signature. - -- Don't work too hard, make some time for fun as well!
