Dave, Thanks for the response, but this makefile was my attempt at getting around Alan's issue. I have re-pasted his makefile below which gives the error he saw. I have found a different way to reproduce the error message as well.

The cause seems to be cp's handling of a .exe file. A simple way to get what I now see as a misleading error message from cp is: $ touch foo.exe $ cp foo bar # note the absence of the .exe extension cp: `foo' and `bar' are the same file Alan's issue arose from the fact that his makefile used a symbol for the resulting executable and gcc naturally appends the .exe in the cygwin environment. When he tries to use the symbol in his cp command, the .exe is not there and cp gives the 'same file' error message. I did some googling and found this issue has been mentioned in several threads. From what I can gather, at least one iteration of fileutils would allow making a copy of a .exe file without using the extension, as long as another file with the same basename and no .exe extension did not exist. It looks like there was some code in fileutils 4.1-1 to handle .exe copies like this, but the code was removed from the released cp in fileutils 4.1-2. http://www.cygwin.com/ml/cygwin-announce/2001/msg00081.html http://www.cygwin.com/ml/cygwin/2003-04/msg00017.html -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
