移植littlevGL版本为7.0 基于linux fb运行
从littlevGL下载基于linux fb运行的littlevGL源码
https://github.com/lvgl/lv_port_linux_frame_buffer
使用cmake构建makefile 安装cmake
apt-get install cmake
在littlevGL目录下编写cmake配置文件CMakeLists.txt
cmake_minimum_required(VERSION 3.5)
project(Ui C)
#set(CMAKE_C_STANDARD 11)
SET(CROSS_COMPILE 1)
set(CMAKE_SYSTEM_NAME Linux)
#设置编译器 用buildroot里面的
set(CMAKE_C_COMPILER "/home/ljh/f1c100s/buildroot-2017.08/output/host/bin/arm-linux-gcc")
SET(TOOLCHAIN_DIR "/usr/bin/")
#SET(CMAKE_FIND_ROOT_PATH "/usr/arm-linux-gnueabi" "/usr/arm-linux-gnueabi/lib" "/usr/arm-linux-gnueabi/include")

#link_directories(/home/biglion/project/buildroot/rootfs/lib)
link_directories(/home/ljh/f1c100s/buildroot-2017.08/rootfs/lib)
#引入所有编译用到的源码目录

注意:每次修改CmakeLists.txt时 最好删除目录下的CMakeCache.txt和CmakeFiles文件
形成Makefile文件
cmake .
编译
make
得到应用程序Ui
发送文件到f1c100s上执行即可看演示效果
发现左上角有闪动的光标 移除方法:
echo 0 > /sys/class/graphics/fbcon/cursor_blink
echo 0 > /sys/class/vtconsole/vtcon1/bind

内容写的很丰富,条理清晰,主要还是使用CMake进行编译,简单易懂
