This thread has been useful to me with several helpful suggestions.
Using MinGW-5.1.3.exe and binutils-2.17.50-20070129-1, I had problems compiling wxWidgets-2.8.3.
Based on comments here, I reverted to windres.exe from binutils-2.17.50-20040824-1, and wxWidgets compiled successfully.
I do have one question, however. When I update the CB source code (using SVN), is it necessary to re-compile wxWidgets with each CB update? In other words, does the creation of the wxWidget dll depend on the CB code?
Thanks,
Bob
