找不到clang库，在项目中发帖提问。被告知要安装clang库, 命令行如下
apt install libclang-dev clang
直接安装报错，apt update更新目录后可以了
docker start rust
rust
docker exec -it rust bash

可能是更新了libc库的原因，它又重新编译，重新下载libchdb。
网络不稳定，下载libchdb失败，用手工方式下载, 然后解压到linux-x86_64-libchdb目录，再按照build.rs的写法建立软链接到系统目录

重新编译，报同样的错，而whereis命令是能找到的libchdb.so，再建立软链接到当前目录（–local方式），通过了。
