Build error on macOSX about lv_port_pc_eclipse

[CharlesHe023]

Seems both of 'main' and 'monitor_sdl_refr_core' handled the he SDL events.

It should be solved here:
https://github.com/littlevgl/lv_drivers/blob/master/display/monitor.c#L299

Have you updated lv_drivers?

It works, Thanks.

In summary, when compiling on mac you need to:

• #define USE_FBDEV 0 // THIS DISABLES USE OF LINUX FB

• Add #ifdef macro around block in monitor.c file

like the following:

Just to be sure. Now, the SDL events are NOT handled in monitor_sdl_refr_core() but handled from the main() like this.

What happes if you comment out the event handling?
