test2 test.c将test1 test2 放到uClinux-dist/romfs/usr/里Make 两次,我发现make一次没装进去。内核编译后下载进开发板，进入系统,运行程序就可测出/dev/fb0有没存在，FrameBuffer有没配置成功。2 minigui移植2.1 安装库和资源1）解压minigui-res-1.6.tar.gz,设置config.linux文件，将编译器设置为arm-elf-gcc。并将安装路径设置为arm-elf-gcc所在的目录。tar zxvf minigui-res-1.6.tar.gz修改config.linuxprefix = $(TOPDIR)/usr/local/CC = arm-elf-gcc然后Make install安装到/usr/local/lib/minigui/res该res 是MiniGUI.cfg 里面资源引用的位置，也是进行移植的资源。prefix = $(TOPDIR)/usr/local/arm-elfCC = arm-elf-gcc然后Make install安装到/usr/local/arm-elf/lib/minigui/res编译器库里的资源2）解压libminigui-1.6.x-linux.tar.gz,修改编译参数tar zxvf libminigui-1.6.x-linux.tar.gz修改libminigui-1.6.2-linux/scripts/mkconfigif check_value
