I’m trying to use BinaryBuilder for a private package, but I am getting some errors that I don’t understand. I can’t share the code, but I’m hoping that something in the error message or in my `build_tarballs.jl` or `makefile` (included below) will spark an idea from someone.

The undefined reference errors are all related to the `CSPICE` library, which is in Yggdrasil.

My setup works for many platforms, but yields the above errors for a few. Most recently it failed for `x86_64-w64-mingw32` and `i686-w64-mingw32`. It may only be Windows platforms where it fails, but I’m not certain, yet.

Does anyone have any ideas for me on how to proceed?

I think this is a link order problem. Try moving `-lcspice` to the end of the link command:

```
$(CXX) $(LDFLAGS) $(LIBS) -shared -fPIC -L$(prefix)/lib -o $@ $^ -lcspice

```

Good catch! Thank you! I knew that within 15 minutes of posting this, one of the many smart people here would spot my error…

Side note, when having this kind of problems it’d be helpful to always show the compiler invocation, not just the error message.
