XCB development: library missing?

[Karel Adams]

I am developing my own application, using the XCB library on Raspbian. Mostly I follow the excellent tutorial on http://www.x.org/releases/X11R7.7/doc/l ... index.html All went well until I wanted to set the title on a window. Since adding the stanza

Code: Select all

  /* Set the title of the window */
  xcb_change_property (c, XCB_PROP_MODE_REPLACE, win,
                       WM_NAME, STRING, 8,
                       strlen (title), title);

it refuses to compile:

Code: Select all

source/C60_init_xcb: In function ‘main’:
source/C60_init_xcb:52:22: error: ‘WM_NAME’ undeclared (first use in this function)
source/C60_init_xcb:52:22: note: each undeclared identifier is reported only once for each function it appears in
source/C60_init_xcb:52:31: error: ‘STRING’ undeclared (first use in this function)

even though I have mentioned xcb_atom both as a header and as a compilation option.

Code: Select all

// general includes
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>

// includes concerning graphical libraries & functions
#include <xcb/xcb.h>
#include <xcb/xcb_atom.h>

// includes concerning the Rpi and its GPIO interfaces

Code: Select all

gcc	-Wall \
	-o bin/myprog \
	-l xcb_atom \
	source/myprog_rpi.c

I have a suspicion there is a library missing but blimey if I could say which one. This is what I have installed:

Code: Select all

I would say undeclared identifier is a compile time error so only affected by source types not libraries.

In fact appears to be a known issue with the example code: http://stackoverflow.com/questions/1106 ... ot-defined
