GUI ENGINE  ver:lastest
packages/gui_engine-latest/src/blit.c: In function 'rtgui_blit':
packages/gui_engine-latest/src/blit.c:1724:31: error: 'RTGRAPHIC_PIXEL_FORMAT_COLOR' undeclared (first use in this function)
     else if (info->src_fmt == RTGRAPHIC_PIXEL_FORMAT_COLOR)

scons: *** [build/packages/gui_engine-latest/src/blit.o] Error 1
scons: building terminated because of errors.

解决办法：
cd rt-thread-3.1.2/include/
vim rtdef.h  找到 enum   RTGRAPHIC_PIXEL_FORMAT_ALPHA, 在其后添加 RTGRAPHIC_PIXEL_FORMAT_COLOR
最终如下：
 947 /* graphic deice */
 948 enum
 949 {   
 950     RTGRAPHIC_PIXEL_FORMAT_MONO = 0,
 951     RTGRAPHIC_PIXEL_FORMAT_GRAY4,
 952     RTGRAPHIC_PIXEL_FORMAT_GRAY16,
 953     RTGRAPHIC_PIXEL_FORMAT_RGB332,
 954     RTGRAPHIC_PIXEL_FORMAT_RGB444,
 955     RTGRAPHIC_PIXEL_FORMAT_RGB565,
 956     RTGRAPHIC_PIXEL_FORMAT_RGB565P, 
 957     RTGRAPHIC_PIXEL_FORMAT_BGR565 = RTGRAPHIC_PIXEL_FORMAT_RGB565P,
 958     RTGRAPHIC_PIXEL_FORMAT_RGB666,
 959     RTGRAPHIC_PIXEL_FORMAT_RGB888,
 960     RTGRAPHIC_PIXEL_FORMAT_ARGB888,
 961     RTGRAPHIC_PIXEL_FORMAT_ABGR888,
 962     RTGRAPHIC_PIXEL_FORMAT_ARGB565,
 963     RTGRAPHIC_PIXEL_FORMAT_ALPHA,
 964     RTGRAPHIC_PIXEL_FORMAT_COLOR,
 965 };
