4. 导入 LVGL 源码
在 grub-core 下建立 lvgl 文件夹
将 LVGL 源码目录下的 src 目录复制到 grub-core/lvgl/
将 LVGL 源码目录下的 lvgl.h 复制到 grub-core/lvgl/lvgl.h
创建文件夹 grub-core/lvgl/port
将 LVGL 源码目录下的 lv_conf_template.h 复制到 grub-core/lvgl/port/lv_conf.h
创建文件 grub-core/lvgl/port/module.c
- #include <grub/dl.h>
- GRUB_MOD_LICENSE ("GPLv3+");
复制代码
修改 conf/Makefile.common,添加
- CFLAGS_LVGL = -Wno-discarded-qualifiers -Wno-redundant-decls -Wno-nested-externs -Wno-suggest-attribute=format -Wno-shadow -Wno-incompatible-pointer-types $(CFLAGS_POSIX)

- CFLAGS_LVGLAPP = $(CFLAGS_POSIX)
- CPPFLAGS_LVGLAPP = $(CPPFLAGS_LVGL) -I$(top_builddir)/grub-core/lvgl
复制代码
修改 grub-core/Makefile.core.def,添加
