如果觉得自己没有能力解决编译过程中的问题，建议用官方推荐的 Ubuntu16 & 17 进行编译。
-
编译用 ./build.sh 烧录用 ./rkflash.sh 。

gcc 过高会出现 mksquashfs 的问题，自行改一下 bwriter_buffer 和 fwriter_buffer 为 extern 变量。
/usr/bin/ld: restore.o:(.bss+0x8): multiple definition of `bwriter_buffer'; mksquashfs.o:(.bss+0x400bf0): first defined here /usr/bin/ld: process_fragments.o:(.bss+0x0): multiple definition of `fwriter_buffer'; mksquashfs.o:(.bss+0x400be8): first defined here /usr/bin/ld: process_fragments.o:(.bss+0x8): multiple definition of `bwriter_buffer'; mksquashfs.o:(.bss+0x400bf0): first defined here /usr/bin/ld: xattr.o:(.bss+0x8): multiple definition of `fwriter_buffer'; mksquashfs.o:(.bss+0x400be8): first defined here /usr/bin/ld: xattr.o:(.bss+0x10): multiple definition of `bwriter_buffer'; mksquashfs.o:(.bss+0x400bf0): first defined here

gcc10 会有 Build error gcc 10.x (SOLVED, PLS FIX ON REPO) multiple definition of 'yylloc' 这个问题。

manjaro 没有 www-data 用户组和用户，自行添加，不然 buildroot 打包时不过
/home/dls/desktop/rv1126_rv1109_linux_v1.5.1_20201109/buildroot/output/rockchip_rv1126_rv1109/host/bin/fakeroot -- /home/dls/desktop/rv1126_rv1109_linux_v1.5.1_20201109/buildroot/output/rockchip_rv1126_rv1109/build/rk_oem/oem_fakeroot.fs
