MTK 指示错误U8类型非法定义

[wuanan8321]

做富贵的文档的练习时，定义了U8类型的变量。
但是却被报错成非法定义：
贴出来给大家围观。。。。。。。。

定义变量：
void mmi_myapp_entry(void)
{
#ifdef __SO_HELLOWORLD__
UI_filled_area filler = {0}; //以颜色为背景的显示方法。
static color g_colors[3] = {{255,0,0},{0,255,0},{0,0,255}};
static U8 perc[2] = {30,70};
gradient_color gc = {g_colors,perc,3}; //结构体， 递进绘画对于 颜色的设置。
//color Board_color_myappp = {0,0,255,255};
CONST_HARDWARE color Board_color_myappp = {0,0,255,100};

把U8的定义放在前面
