I am on MacOS Mojave 10.14. I can compile wxWidget code and have compiled a few demos, etc. The only feature of wxWidget I cannot compile is a wxRichTextCtrl. Whenever I do the following in my main.cpp file I get error:
wxRichTextCtrl* richTextCtrl = new wxRichTextCtrl(this, -1, wxT(""), wxDefaultPosition,
wxSize(250, 150), wxTE_MULTILINE);
I get this error
Undefined symbols for architecture x86_64:
"wxRichTextCtrl::wxRichTextCtrl(wxWindow*, int, wxString const&, wxPoint const&, wxSize const&, long, wxValidator const&, wxString const&)", referenced from:
MyFrame::MyFrame(wxString const&, wxPoint const&, wxSize const&) in main-498ba7.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
I have tried replacing "this" with a wxPanel, but that results in the same error. The full error report from g++ is:

I compile from my terminal using g++ and get my linker options, etc from wx-config --cxxflags and wx-config --libs. I program in xCode. Using gcc instead of g++ results in the same error.
By default, wx-config --libs returns only the "standard" libraries (which basically were all the existing libraries back when this was implemented) and not all the available libraries to make it possible to add more libraries later without changing anything for the applications that don't need them.
So if you need to use a library not included in this "standard subset", you must specify it explicitly, like this: wx-config --libs std,richtext.
