Can't build a go module built with Swig due to missing include path

Question

In my swig interface file I use includes such as:

%{
    #include "lib-cpp/types/lists/linked-list.hpp"
%}
%include "lib-cpp/types/lists/linked-list.hpp"

However when I run go install I get:

navdb_go_client_wrap.cxx:258:14: fatal error: 'lib-cpp/types/lists/linked-list.hpp' file not found

How do I specify an include directory for go install?

Answer 1

Exporting CPLUS_INCLUDE_PATH to the required include path fixed this.
