使用SDK构建debian系统失败

微信用户-T8mzAz

按照文档2.7节进行操作，构建时出现如下错误：


make[2]: *** [debian/rules:4: build] Error 2
dpkg-buildpackage: error: debian/rules build subprocess returned exit status 2
make[1]: *** [scripts/package/Makefile:80: bindeb-pkg] Error 2
make: *** [Makefile:1519: bindeb-pkg] Error 2
ERROR: Running build_kerneldeb failed!
ERROR: exit code 2 from line 702:
    make ARCH=$RK_ARCH bindeb-pkg RK_KERNEL_DTS=$RK_KERNEL_DTS -j$RK_JOBS

看提示是编译内核失败。编译机版本是：
LSB Version:    core-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.6 LTS
Release:        20.04
Codename:       focal
不知道什么原因，希望有人能解答一二。谢谢

おおおじ。

单独构建下内核看下什么报错，
./build.sh kerneldeb

这是单独构建内核出现的信息，看信息好像是缺少built-in.a这个文件、
