opencv 多线程显示出现以下错误：

[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
Blurring_Images: ../../src/xcb_io.c:178: dequeue_pending_request: Assertion `!xcb_xlib_unknown_req_in_deq' failed.
The program has unexpectedly finished.

解决办法：

通过链接X11，包含xlib库和调用XinitThreads

例如：

// main.cpp
#include <thread> 
#include <X11/Xlib.h>

int main() {
   XInitThreads();
   // . . . 
}

g++ main.cpp -o my_program -std=c++0x -pthread -lX11 /* -pthread if you're on Linux */




当然还是链接你的其他生成库
