This thread is not dead. The result of this shows that Cygwin can at the moment be told to execute code without having a correct executable file (also COFF format). Cygwin should have detected a non-executable file and have refused to launch it. What happens here on NT: if you use incorrect syntax by appending .exe in g++ cmd : $ g++ -mno-cygwin -c cpplus.cpp -o cpplus.exe ; g++ -mno-cygwin -c cpplus.cpp -o cpplus $ ls -l cpplus cpplus.exe -rw-r--r-- 1 Nom 544 1855 Jul 21 20:38 cpplus -rwxr-xr-x 1 Nom 544 1855 Jul 21 20:41 cpplus.exe finally tring to launch it: $ ./cpplus BASH: ./cpplus: Permission denied $ ./cpplus.exe runs and hangs. (note that under Windows ME it doesn't run,saying permission denied though it's detected as executable by ls). two problems: - ls should show non executable file (problem in cygwin filesystem /ls excutable detection routine) - incorrect code can be launched on NT systems. ___________________________________________________________ Do You Yahoo!? -- Une adresse @yahoo.fr gratuite et en français !
