I would like to be able to display remote client in a simple OpenGL application. "Simple" means only display the client such as a texture.

I started to look the VNC protocol but due to their popularity I only have few documentation related to VNCViewer. About RFB the only documentation is: http://www.realvnc.com/docs/rfbproto.pdf which is cool to understand the protocol but not enough to use it in a C++ OpenGL application. Then I found: http://libvnc.github.io/

I tried to compile the example (downloaded from github). So I added into my qtproject all rfb headers files run cmake on some of them. Then I built it but got the error:

undefined reference to `rfbMakeXCursor' and many others related to rfbXxxxx

rfb.h contains declarations to those "undefined" errors. I don't understand what did I do wrong. Has anybody already made it work?

I'm working on Windows 8.1 64bit using C++ qtCreator and MinGW.

Headers are just ""able of contents" for the compiler to know, which functions can be called. You need to actually link to the library. The odds are, that since you've got it from GitHub you must first build the library. The built library you then add to some "extras/lib" directory in your project, configure that directory as additional library directory and add the library to the linker flags.
