1、camera_engine_rkisp is in the dependency chain of app_demo that has added it to its _DEPENDENCIES variable without selecting it or depending on it from Config.in. Stop.
解决方案：
注释：rv1126/buildroot/package/rockchip/app_demo/Config.in中的
#config BR2_PACKAGE_APP_DEMO_RMSL
bool "Rockchip Module Structured Light demo"
select BR2_PACKAGE_CAMERA_ENGINE
select BR2_PACKAGE_MPP
select BR2_PACKAGE_LINUX_RGA
2、2024-03-21T02:52:45 configure: error: you should not run configure as root (set FORCE_UNSAFE_CONFIGURE=1 in environment to bypass this check)
解决方案：
vim /etc/profile
在文件末尾添加 export FORCE_UNSAFE_CONFIGURE=1 保存
source /etc/profile
3、you need to install 'unbuffer' (from package expect or expect-dev)

7、/usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of `yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here
解决方案：
1、解决Linux下交叉编译U-Boot源码时报'multiple definition of `yylloc''的错误-CSDN博客
2、我在22.04上编译遇到了这个问题，上面链接的博客没有解决该问题，我把ubuntu降级到 20.04, gcc & g++ 版本使用version 9.4.0，就解决了
