There seems to be a problem with Cygwin's quilt. This simple example simply alters a #define from 'MESAGL' to 'NX_MESAGL'. That's it. New quilt created, ok. New patch, ok. Edit file, ok. Refresh (create patch), ok. Rollback changes, ok. Reapply patch.. error: >>> quilt push >>> Applying patch test.patch >>> patching file Imakefile >>> Hunk #1 FAILED at 2. >>> 1 out of 1 hunk FAILED -- rejects in file Imakefile >>> Patch test.patch does not apply (enforce with -f) Extract quilt_cygwin_bug to a directory, cd in, and run 'quilt push' to generate the error. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
