I am trying to compile minimal sample for wxWidgets, I have everything that is needed all headers and all lib files. But I can compile the code. Which libs are required to compile minimal sample?

I get this error

and I have linked these libs (just in case), and I still can't compile this.

wxmsw29ud_core.lib
wxbase29ud.lib
wxtiffd.lib
wxjpegd.lib
wxpngd.lib
wxzlibd.lib
wxregexud.lib
wxexpatd.lib
wxmsw29ud_media.lib
wxmsw29ud_xrc.lib
wxmsw29ud_stc.lib
wxmsw29ud_richtext.lib
wxmsw29ud_propgrid.lib
wxmsw29ud_qa.lib
wxmsw29ud_adv.lib
wxmsw29ud_html.lib
wxmsw29ud_aui.lib
wxmsw29ud_webview.lib
wxmsw29ud_gl.lib
wxscintillad.lib

These errors look like the .lib files dont contain all the required symbols (but do contain some) so I assume the rest are found in the .dll file.

So, if I recall from my experience with wxWidgets, you need to define "WXUSINGLDLL".

The setup.h *should* contain this, but unfortunately is quite fiddly on Windows using Visual C++ for some reason and doesn't always seem to be correct by default (especially with the recent binaries).

So basically add /D"WXUSINGDLL" to the command line flags (or in the IDE settings) and rebuild your project.

Ok thanks I solved this, it seems that compiler ignores /D"WXUSINGDLL" for some reason, but it works when WXUSINGDLL and wxMSVC_VERISON_AUTO are placed in preprocessor definitions.

Seriously consider looking at Qt instead of wx. You'll thank me in the long run....
