Just updated my Cygwin. If I use cp to copy a file, in this case an executable, I get "This program cannot be run in DOS mode" when I try to run the copied file.
The copied file also now differs from the original.
$ ls -l /bin/sum.exe -rwxr-x---+ 1 sam Users 26624 Dec 21 02:32 /bin/sum.exe
$ cp /bin/sum.exe copysum.exe
$ ls -l copysum.exe -rwxr-x--- 1 sam None 26713 Dec 22 14:35 copysum.exe
$ cmp /bin/sum.exe copysum.exe /bin/sum.exe copysum.exe differ: char 119, line 1
$ ./copysum.exe This program cannot be run in DOS mode.
Anybody else experiencing this? I have tested this out on three different computers that have been updated today, all produce the same results. On a box thats running the older cygwin, cp copies the files exactly and I have no trouble running them.
Thanks, Sam
Works fine for me. Maybe you'd better do
$ which cp $ which ls
...and for good measure,
$ /bin/sum.exe
Ok.
$ which sum.exe /usr/bin/sum.exe
$ /usr/bin/sum.exe
and $ sum
(both just hangs waiting for input)
$ cp /usr/bin/sum.exe copysum.exe
$ ls -l /usr/bin/sum.exe -rwxr-x---+ 1 sam Users 26624 Dec 21 02:32 /usr/bin/sum.exe
$ ls -l ./copysum.exe -rwxr-x--- 1 sam None 26713 Dec 22 15:19 ./copysum.exe
$ ./copysum.exe This program cannot be run in DOS mode.
$ find / -name "sum.exe" /bin/sum.exe /usr/bin/sum.exe
And I have no alias's to cp. (or any other aliases)
For clarity,
$ which ls /usr/bin/ls
You may find that /bin/sum.exe is *not* what you run when you run "sum".
FYI, for me, running sum or ./copysum.exe just hangs, it is waiting for stdin. So I ran the --version option to each, just to see them do something.
