问题一
~/linux/linux-5.2.8$ make s3c2410_defconfig
HOSTCC scripts/basic/fixdep
/bin/sh: 1: scripts/basic/fixdep: Exec format error
make[1]: *** [scripts/Makefile.host:90：scripts/basic/fixdep] 错误 2
make[1]: *** 正在删除文件“scripts/basic/fixdep”
make: *** [Makefile:507：scripts_basic] 错误 2
$sudo apt-get install build-essential安装gcc相关软件，然后把hostcc改成gcc-----ok问题二
~/linux/linux-5.2.8$ make menuconfig
*
* Unable to find the ncurses package.
* Install ncurses (ncurses-devel or libncurses-dev
* depending on your distribution).
*
make[1]: *** [scripts/kconfig/Makefile:206：scripts/kconfig/mconf-cfg] 错误 1
make: *** [Makefile:562：menuconfig] 错误 2
根据提示安装sudo apt-get install libncurses-dev
问题三
"mkimage" command not found - U-Boot images will not be built
make[1]: *** [arch/arm/boot/Makefile:91：arch/arm/boot/uImage] 错误 1
make: *** [arch/arm/Makefile:339：uImage] 错误 2
mkimage的命令找不到，说明我们缺少了一些依赖包，所以我尝试安装依赖包如下
sudo apt-get install uboot-mkimage
