compilation errors: BONMINLIB_EXPORT and bad ld name

[BrannonKing]

When I try to compile Couenne I get this error:

./../src/main/CouenneBab.cpp:45:8: error: ‘BONMINLIB_EXPORT’ does not name a type; did you mean ‘COUENNELIB_EXPORT’?
   45 | extern BONMINLIB_EXPORT Bonmin::OACutGenerator2 *currentOA;   // pointer to the OA generator

My OS is a fairly recent version of Manjaro. Also, the build file should specify the required C++ standard. There are a lot of warnings when compiling with C++17 (the default on my machine). If I switch the export macro to the suggested one, it still doesn't fully compile for me. It fails at the very end with this error:
