普通的编译的cmake很多教程返利 我的lvlg模拟器就是cmake的
但这arm-none-eabi 就不行了。老提示

The C compiler

  "C:/Program Files/PROS/toolchain/usr/bin/arm-none-eabi-gcc.exe"

is not able to compile a simple test program.

It fails with the following output:

我尝试使用这个功能。
但他似乎无效。
/ **

画一个矩形
@param cords_p矩形的坐标
@param mask_p矩形将仅在此蒙版中绘制
@param style_p指向一个样式的指针
/
void lv_draw_rect（const lv_area_t * cords_p，const lv_area_t * mask_p，const lv_style_t * style_p）;

我在想他是不是一定要在一个空屏幕上绘制的.我这建立了一个PAGE 所以没用.还是我压根弄错了.
主要我做个利用PIXY颜色传感器识别东西的模块.

问了一个很弱智的问题 请版主删除不好意思
