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


i have installed packages in cygwin. have added c:\cygwin\bin path variable. when try compile c++ file in command line error 'access denied'. same commands work in cygwin batch window. know what's wrong?

edit: changed permissions gcc , g++. no longer 'access denied' error, new one: "this version of c:\cygwin\bin\g++.exe not compatible version of windows you're running. check computer's system information see whether need x86 (32-bit) or x64 (64-bit) version of program, , contact software publisher.".

enter image description here

enter image description here

because c:\cygwin\bin\gcc.exe isn't executable file, it's cygwin symbolic link.

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

the underlying file runs fine.
