cygwin1.dll missing when compiling c++ with g++

I'm using cygwin and when I'm compiling hello world with gcc somehow the compiler doesn't understand about using std namespaces (some of them are missing), but when I compile with g++ yes they work. But when I click on the helloworld.exe it says that cygwin1.dll is missing.

Is there anything can I do?

Solution

  • "gcc" is the C compiler - and namespaces are not a part of the C language. "g++" is the C++ compiler, so it will understand namespaces.

    Try the no-cygwin option when compiling to produce executables that depend on the mingw runtime instead of the cygwin runtime (which, AFAIR, introduces licencing issues).
