工程代码lv_port_linux_frame_buffer
使用工具LvglFontTool生成myFont.c添加到lvgl/scr/lv_font目录下
修改lv_conf.h中
#define LV_FONT_CUSTOM_DECLARE LV_FONT_DECLARE(myFont)
测试代码提示myFont 未定义
void lv_font_test()
{
LV_FONT_DECLARE(myFont);//放这里也行
lv_obj_t* label1 = lv_label_create(lv_scr_act(), NULL);
lv_obj_set_style_local_text_font(label1, LV_LABEL_PART_MAIN, LV_STATE_DEFAULT, &myFont);
lv_obj_set_pos(label1, 20, 20);
lv_label_set_text(label1, "Hello,你好,哇酷网!");
}
myFont.c好像没有编译，
求教怎么把myFont.c加入编译进去？

Makefile文件找到你当前.c文件名，然后把myFont.c一起挤进去
应该不是改Makefile，
不好意思，我没问对问题。应该是lv_conf.h应该怎么修改才能使用自定义的字库？
只把myFont.c加入lv_font目录和声明LV_FONT_DECLARE(myFont);不够吧？
Makefile是这样的：

2、在CMakeLists.txt中 lvgl/src/lv_font/lv_font_montserrat_48.c 附近添加lvgl/src/lv_font/myFont.c。
这一步在CMakeLists.txt没找到对应内容lvgl/src/lv_font/lv_font_montserrat_48.c

修改lv_font目录下lv_font。mk，后面加+=myFont.c编译通过
