[linux-audio-user] Fw: FreeWheeling 'Xlib async reply' fix - Linux-audio-user

6 Jan 2005

Hi,

I wanted to pass this back to linux-audio-user for anyone who is having an
issue with an Xlib error: 'Xlib async reply' when FreeWheeling starts up.

Several people have reported this. Here's a fix that seems to work:

...
 JP, the fix you suggested:

1) In src/fweelin_core.cc, find:

  mlockall(MCL_CURRENT | MCL_FUTURE);

Directly after, add these lines:

  if (!XInitThreads()) {
    printf("MAIN: ERROR: FreeWheeling requires threaded Xlib support\n");
    return 0;
  }

And near the top of src/fweelin_core.cc, find:

  #include <sys/mman.h>

Directly after, add:

  #include <X11/Xlib.h>

seems to have worked.  Haven't tried the other one, my Xlib problem is
gone.  It in fact is a very pleasant app and I think it will become a
part of my arsenal.  I am looking forward to the stereo capabilities
:) 
This fix will appear in the next prerelease. 

Once again, thanks for all your tremendous feedback- already I am glad I went
the open-source route.

Best,
JP Mercury
