Post your main function in code tags.

You likely failed to declare a main function or declared it wrong.

Edit: I think wxApp or wxAppConsole is the main function in wx apps.
Edit2: IMPLEMENT_APP(CodeBlocksApp) is how Code::Blocks declares its main app.

main.cpp include section // For compilers that support precompilation, includes "wx.h". #include "wx/wxprec.h" #ifdef __BORLANDC__ #pragma hdrstop #endif #include <winsock2.h> #ifndef WX_PRECOMP #include "wx/wx.h" #endif #include "main.h" #include "SimpleSerial.h" It builds using the above for me; I...

Including "wx/wxprec.h" inside of a header is a bad idea. Including "wx/wx.h" inside of a header is *not* a good idea unless the header is being used to generate a pre-compiled header. It is better to include them inside of an cpp file. Edit: But, the above is not a likely cause of your build issue....

What headers are included by your application? If you include "windows.h" you need to replace that with the wx header file that wraps that include. It is called something like "wx/wrapwin.h". Edit: Looks like this is not the cause of the error. Can you post a small program that has this error? Tim S.

No idea if this link might help you.

If you are trying wxGTK/Win you might want to look at my mingw-w64-wxWidgets-git package

Have you tried using my Msys2 package of mingw-w64-wxWidgets3.1 ?

https://github.com/msys2/MINGW-packages ... Widgets3.1

No binary supplied; but, it should build without problems using "makepkg-mingw".

You could report to the location you got the wx-config ported to windows from; but, it might be a waste of time.

Edit: I am no longer using wx-config.exe and I know of no group other CodeLite that seemed to be using it on a regular basis.

So, you have an IDE that says a warning is an error; you might wish to figure out how to get the real compiler response instead of the IDE response. But, this might not be possible with your IDE.

You really need to learn the difference between an compiler error and a compiler warning!

"E:\Code Blocks\test\testApp.cpp" -o obj\Debug\testApp.o Code::Blocks does not have issues with spaces to my knowledge; but, some GCC builds (esp. windres) do have issues with spaces. They also tend to have issues with non ASCII characters in path; did not see any in your post. Edit: It may also be...

If you are still trying to build wxX11 see https://trac.wxwidgets.org/ticket/16813

Edit adding configure option --enable-monolithic should avoid this build error.

According to wxWidgets docs that I have read in the past 24 hour. Cygwin (Native GCC) should be able to build three wx toolkits wxGTK wxX11 wxMotif Once, I get all three of them to build using Cygwin 32 bit. I will create the updated documentation and do a Pull Request. By then, I will likely know i...

Maybe it's time to ask on the mailing list / Google group where you can reach the core developers: https://groups.google.com/forum/#!forum/wx-users Noop, I would not ask there; till I fail to make progress. Already got the OP fix and the same fix works on wx 3.0 git branch. Edit: I am one of the fe...

wxWidgets git master needed the below command to build wx base library; still building core and the other libs. Edit: Just error-ed out with new error building wx core lib. The error looks to be 64 bit only issue. CPPFLAGS='-D_GNU_SOURCE' \ ../configure --with-gtk --enable-debug --enable-unicode --w...
