c++ - Get "Access is denied" when trying to compile with g++ from command line. Cygwin

Question

I have installed all packages in cygwin. I have also added C:cygwinin to my PATH variable. But when I try to compile a c++ file in command line I get the error 'Access is denied'. The same commands work in the cygwin batch window. Does anyone know what's wrong?

Edit: I changed the permissions for gcc and g++. I no longer get the 'Access Denied' error, but get a new one: "This version of C:cygwining++.exe is not compatible with the version of Windows you're running. Check your computer's system information to see whether you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contact the software publisher.".

Answer 1

Because c:cygwiningcc.exe isn't an executable file, it's a cygwin symbolic link.

$ file /bin/gcc
/bin/gcc: symbolic link to `/etc/alternatives/gcc'
$ file /etc/alternatives/gcc
/etc/alternatives/gcc: symbolic link to `/usr/bin/gcc-4.exe'

The underlying file runs just fine.

C:cygwinhomeBen>gcc-4 --version
gcc-4 (GCC) 4.5.0
