Rename fails if the source and >destination are on different filesystems. If this is the case, then there is a bug in cygwin32's rename. patch knows rename will fail if they are on different "filesystems" (drives) and copies the output file if that happens. While I didn't try to track down what cygwin32's rename does incorrectly (wrong return codes?), I did verify it was the problem by using the rename.c supplied with patch-2.1 instead. Doing so fixes the problem on my system -- output files are now created. > You shouldn't >mount /tmp, just have one in the root of every physical drive. Sounds like you're using a non-cygwin32 implementation -- drive letters don't exist in cygwin32. If I run patch from /apps/test (E:\ is mounted as /apps), how is patch supposed to figure out it wants put its temporary files in E:\tmp (/apps/tmp) instead of /tmp? Even if it could, why would the Unix-derived GNU patch program attempt to do so? If it did, you would have to have a tmp directory at the root of each filesystem in Unix as well. -- James Dumser 972-462-5335 dumser@ti.com - For help on using this list, send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
