Can't get wxWidgets to work

Dodle · December 18, 2008

Hello, I am new to the forum, and pretty new to programming as well. I have been using wxWidgets with Python but recently wanted to learn C++. I am running Windows XP Pro. I am trying to compile the program from this page.

I've installed wxWidgets and am using Mingw32 for my compiler. I'm having a lot of trouble. Here is the command I have been using to compile:

c++ sample.cpp -o sample

I get the following error:

wx/wx.h: No such file or directory
wx/sizer.h: No such file or directory

I tried adding WXWIN environment variable with no effect. So I started telling the compiler where wxWidgets was installed:

c++ sample.cpp -B C:/Env/wxMSW-2.8.9 -o sample

Apparently with this the compiler found wxWidgets, but is still giving me errors. Too many errors to paste in here. Here is part of what prints out:

Does anyone know what I am doing wrong?

I don't know either wxWidgets nor Mingw32. But what I can see is that you get lots of 'undefined reference' messages. Try to find in what header (.h) file these are defined, and see if adding an #include for that file improves things.

Also I wonder if changing C:/Env/wxMSW-2.8.9 (in the c++ command) to C:\Env\wxMSW-2.8.9 would change anything?

Dodle · December 19, 2008

Okay, I've started using Dev-C++ which allows me to define where my libraries are located. It seems to have fixed some things, but now I'm getting a bunch of Link Errors like the following:

  [Linker error] undefined reference to `wxFrameNameStr'

Still, possible missing #include.

I moved setup.h into \include\wx, now I get the following errors. I have tried including different header files.

You have to place the #include statements in the right order, e.g. the one containing the missing definitions before chkconf.h
