Compilation error on Visual Studio 2026

[Gatti Gianluca]

Hello guys,

I am still having problem on compiling a (simple) wxWidgets application with Microsoft Visual Studio 2026.

I wanted to install the new version 3.3.3 and, as usual, I followed the instructions of the online documentation: https://docs.wxwidgets.org/3.3.2/plat_msw_binaries.html

But I got a lot of errors:

 

I also used the last wxwidgets.props file from the github repo (as it was suggested me in an other email).

I also tried to retarget the solution to VS2022 (v143 build toolset), but I got the same errors.

Can someone help me?

Thank you!

If it can help to solve the problem: the IntelliSense recognize everything except wxThread (see the image):

Hi, did you build wxWidgets yourself or are you use the pre-built binaries?

From the missing setup.h errror, it looks like you are trying to use static Win32 Debug libraries (vc_lib/mswud).
I think the only pre-built binaries available are shared x64 (vc_x64_dll).
If you want to use these, you need to change your own project to be x64 (and dll/shared?) as well.

If you want to use static 32bit libraries you'll need to build wxWidgets yourself.
Open wxDir/build/msw/wx_vc18.slnx, select the Debug Win32 solution and build the solution.
Now wxDir/lib/vc_lib/mswud/wx/setup.h and the libraries should have been created.
To build Release/x64/shared libraries, select the desired solution and build it.

Thank you Maarten.

So, If I need Win32 application I have to build wxWidgets from source; I will do, thank you.
