I use VERBOSE=1 to get insight in the build process, but that was of little use - most of the details are hidden in temporary files. So I checked the dependencies file (CXX.includecache) and saw only include files from d:\wxwidgets. Then I compiled the source file using the flags in flags.make and the -E option to get the preprocessed source and found that both wxString and wxSize were defined as expected (and used all over the place). So I sought the .lib files (so-called import libraries) for the symbols that were missing. None contained exactly those strings.

Okay, I went back to the wxWidgets site, downloaded the latest version (as that was advertised). Exact same problem. Then I noticed something - there were separate distributions for 32 bits and 64 bits environments. And then it hit me: I had downloaded the _wrong_ bits version. From there on it went quite smoothly. After some struggles with the path I got the build to succeed and got an example to run. The only (!) problem left is that on line 378 in wxwidgets_dev.cpp the variable "offset" is used but was not previously set. This causes a debug error under MSVC:

A quick check of the source code did not tell me how to solve that, so I will have to leave that to you.

By the way, the correct 64-bits libraries are installed in a directory containing the "x64" suffix. So my earlier change was (a) not necessary (b) an indication I had downloaded the wrong libraries. If only they had used "x86" or "x32" or something for 32-bits versions ...

Regards,

Arjen
