Did you start with a completely clean wx source after changing setup.h.in? 
This file is converted into something else, quite early in the build

Ok, I don't particularly care about compiling 2.6 manually, either 
distributions have it or they don't, in which case people should use 2.8

CPPunit itself does not interact with wx as far as I know. There is a wx 
test runner in cppunit that has a WX gui, but we don't use it. Wx may have 
an option to use cppunit for wx tests, but I've never heard about that, 
nor used it.

We have our own library of wx test functions, based on Reinhard Fureder's 
work, which we use to generate simulated wx events in cppunit tests, to 
drive the gui from cppunit tests. The integration of cppunit and wx in 
this way is very hairy and complex, I recommend that you don't touch it.

What is bugbug and why is it not required? :)
Zlib is required for boxi because it's required for box backup.

Don't know if they need changing. Unicode is certainly required.

I guess it doesn't work on mingw then, so it should be turned off.

What is this doing in the wx configuration line?

I've seen this problem as well, but I don't think it's the correct 
solution. Instead, just remove the line from configure.in that moves 
Makefile to Makefile.in.

You can't just change that file, it will result in link errors as you saw. 
You have to get wx to use and install the correct version when compiling.

Yes, some of these don't work with mingw.

Cheers, Chris.
