$ ./a.out
X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
  Serial number of failed request:  8
  Current serial number in output stream:  8

应该使用:gcc c.cc -lX11
并将一个字符串更改为:XSelectInput(display, root, ButtonReleaseMask);
