And here's the error I get:

I can see that the author is attempting to fix problems with just building this:

• rpav/c2ffi@f02bc05
• rpav/c2ffi#61

I have tried using other commits, and I get different errors, but errors none the less.

If I look at that library, I see the undefined symbols:

$ nm -g /gnu/store/8fmqjg2flrx4wafpxacw8fmia84amg33-clang-8.0.0/lib/libclangBasic.a |gr
ep _ZN4llvm14MCSectionMachO21ParseSectionSpecifierB5cxx11ENS_9StringRefERS1_S2_RjR

                 U _ZN4llvm14MCSectionMachO21ParseSectionSpecifierB5cxx11ENS_9StringRefERS1_S2_RjRbS3_

ParseSectionSpecifier is defined here: https://llvm.org/doxygen/MCSectionMachO_8cpp_source.html#l00182

StringRef is defined here: http://llvm.org/doxygen/StringRef_8h_source.html#l00048

How do I tell which symbol is missing?

The README for c2ffi has some pointers: https://github.com/rpav/c2ffi/blob/llvm-8.0.0/README.md#notes but I'm not sure what to make of this.
