Hello, And many thanks for your (all) help.  I managed to compile xcb with success, but have still a few minor problems.   I can compile all the demos and tests in .../xcb-demo.  It shows no compilation errors.  But when running the programs, they just print a lot of garbage on the terminal window and exit with a segmentation fault.

So testing XCB itself means either running our demo applications, or writing some of your own -- which we'd be happy to help you with. </pre> <blockquote type="cite"><pre>Unfortunately, I do not fully understand howto install the various parts.
