x11 code does not compile in Code Blocks

I am currently running the latest version of Code-blocks in Ubuntu 11.04. I have GTK+2, and 3 developer libraries fully installed (and working), and presumably have x11 installed. The header files are there.

However, a simple code will not compile using x11 coding.

#include "X11/Xlib.h"

int main() {
    Display *display = XOpenDisplay(0);
    Window root = DefaultRootWindow(display);
    XWarpPointer(display, None, root, 0, 0, 0, 0, 100, 100);
    XCloseDisplay(display);
    return 0;
}

This give me the readout of:

obj/Release/main.o||In function `main':|

undefined reference to `XOpenDisplay'

undefined reference to `XWarpPointer'

undefined reference to `XCloseDisplay'

|=== Build finished: 3 errors, 0 warnings ===|

I've tried reading multiple webpages of 'linking' x11, I only find headerfiles, and not the file type asked by the linker within the compiler (That's the wrong term for that.. it's not a compiler.. it's something else.. I know. Apologies)

In CodeBlocks you can just set in the project options libraries to link against, setting -lX11 in the compiler settings will make every program you compile with codeblocks link against X11.

Thanks! I just had the same problem. To spell it out:

Settings > Compiler and Debugger > Linker settings > Other linker options > "-lX11"

For the record 'codelite' got it right all by itself.

I don't know what Code Blocks is, but for a normal compile/link process, you need to specify -lX11 to link with libX11.so for the Xlib functions.
