nanogui: Thread: "wrong packet type" using threads in uclinux

Hi there,

 

I'm using Nano-X under uCLinux in a ColdFire processor.

My project works fine in my PC (Nano-X + X11), but now I'm having some
problems with Nano-X in the uCLinux environment (FrameBuffer).

When calling some nano-X functions from a second thread, the application
fails and I get the following error message:

nxclient 36: Wrong packet type 0 (expected 53)

nxclient 26: Wrong packet type 0 (expected 22)

nxclient 36: Wrong packet type 1005 (expected 53)

nxclient 36: Wrong packet type 0 (expected 53)

 

These functions work perfectly when called outside the thread or when I
don't use threads.

 

Are you aware of any issues with nano-X in a multi-threaded environment?
Any workarounds?

 

Thanks in advance, 

Luis Reynoso

Of course, you need to have nano-X compiled with THREADSAFE=Y

If it works with threads on the desktop with THREADSAFE=Y,
but not on the target, you may have a thread library issue.  See
the include/lock.h file for comments, make sure you're running
the right threads defines for your threads package.
