当我在 ubuntu20.04 上使用 flex builder 编译 tsntool 时，发现无法访问“的错误我读了另一篇文章那个来源。 codeaurora.org 停止服务了，那么现在有什么办法可以编译 tsntool 吗？
hingw@ubuntu:~/ls1028/flexbuild_lsdk2108$ flex-builder -c tsntool
COMPONENT: tsntool

另外，我在github上看到tsntool源码包，编译器说明指定了一个kernal源码路径，这个路径应该填什么？
1. Libraries requirement
Libraries libnl-3.0, libtermcap, libreadline libcjson are needed.
2. How to compile the tsntool:
2.1 Setup cross compile environment
2.2 Compile binary:
> source source_arm64.sh
> make
The tsntool and libtsn.so will be generated.
