我试图在Rust中封装一个 相当大的C库。我使用bindgen生成绑定代码，Rust似乎对此很满意。然而，尽管我尝试了不同的方法并且多次阅读了构建脚本文档，但我仍然遇到链接问题。
我正在使用的库有一组csh脚本，最终会构建两个
我目前通过从我的测试中调用常量和函数来测试正确的绑定，参见lib.rs（在我的Github上）。
我高度怀疑我的
链接错误。

.a文件：cspice.a和csupport.a。它们都存储在我的项目的cspice_linux_gcc_64bit/lib中（参见下面的树形结构）。我目前通过从我的测试中调用常量和函数来测试正确的绑定，参见lib.rs（在我的Github上）。

build.rs或者较少可能的是我的Cargo.toml存在问题。链接错误。
