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
