The other help I need with this issue is for someone to build wxWidgets following the MinGW/MSYS recipe I gave at the start of this thread to see if there are any linking issues in that case. I am virtually positive there will be such linking issues since we are dealing with the same wxWidgets version, the same build recipe and almost the same (4.7.2 versus 4.7.0) versions of MinGW/MSYS. Also, such linking issues have occurred (e.g., in the qt device driver case) on Microsoft Windows platforms as well. But my current thinking is the diagnostics for those linking issues will be much clearer for the Microsoft Windows implementation of LoadLibrary and/or GetProcAddress than for the Wine implementations of those same functions. And at least for the Microsoft version of Windows, the diagonostics will be even better using GetLastError if someone will step forward to implement that approach.
