盛科7132版本编译记录-优快云博客

7132编译总结：
1.新增具有root权限的用户，rootfs系统编译时不能使用root，否则很麻烦，编译出来后命令使用会出问题
useradd zhuwei_new
passwd zhuwei_new
usermod -aG wheel zhuwei_new
nano /etc/pam.d/su
找到以下行：
   auth required pam_unix.so
在这一行下面添加以下内容：
   auth sufficient pam_wheel.so trust use_uid
   保存退出
echo "ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/zhuwei_new
使更改生效：
chmod 440 /etc/sudoers.d/zhuwei_new


2.在1操作后，在home目录下会生成zhuwei_new目录，
   将7132版本拷贝到zhuwei_new目录下，直接使用zhuwei_new用户编译内核和文件系统。
   cp -r ./configs/centec_64_defconfig ../output/rootfs/rootfs_output_64/.config
   ./ctc_mk.sh -c rootfs -a arm64 normal
   错误1：

   You have PERL_MM_OPT defined because Perl local::lib
   is installed on your system. Please unset this variable
   before starting Buildroot, otherwise the compilation of
   Perl related packages will fail
   make[1]: *** [core-dependencies] Error 1
   恢复变量：unset PERL_MM_OPT

   重新编译：./ctc_mk.sh -c rootfs -a arm64 normal

   错误2：

   解决办法：可能是ctc_mk.sh中build_linux4_19函数中使用-j24引起的，虚拟机只有2核，改成-j2，问题解决
