Solving 'Symbol Not Found' Error on Windows When 'bin' and 'lib' Coexist

[whynothackme]

Under Windows, when 'bin' and 'lib' exist together, you might encounter an error that says it can't find the symbol. I've linked a minimal example here for you to take a look: https://github.com/whynothackme/test_cxx.git. If you delete lib.rs, you should be able to compile and link normally. However, if lib.rs exists, you'll probably encounter a 'symbol not found' error.

I got the same problem: https://github.com/dtolnay/cxx/issues/1247. It seems like it is an easy found problem, but I don't know how to tune it to work.

Now I move the bridge code into the lib.rs, and change the build.rs from "cxx_build::bridge("src/main.rs")" to "cxx_build::bridge("src/lib.rs")", it works.

Add "l static=cxxbridge-demo" to lib crate is not the proper way, it still doesn't work if the cpp code in a extern cpp lib. So just remember: only one crate per build.rs
