我在MacOS Mojave 10.14上。我可以编译wxWidget代码，并已经编译了一些演示等。我无法编译的wxWidget的唯一功能是wxRichTextCtrl。每当我在main.cpp文件中执行以下操作时，都会出现错误：

wxRichTextCtrl* richTextCtrl = new wxRichTextCtrl(this,-1,wxT(""),wxDefaultPosition,wxSize(250,150),wxTE_MULTILINE);

我收到此错误

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&,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)

我尝试用wxPanel替换“ this”，但是导致相同的错误。来自g ++的完整错误报告是：

我使用g ++从终端进行编译，并从wx-config --cxxflags和wx-config --libs获取链接器选项，等等。我用xCode编程。使用gcc而不是g ++会导致相同的错误。
