Compilation issues after updating wxWidgets via vcpkg

[Tim Burgess]

Hi,

 

I’m getting:

 

error C1189: #error:  "wxUSE_WEBREQUEST must be defined, please read comment near the top of this file."

 

I’ve read the indicated comment and understand that I’ve got a file mismatch between setup.h in my project and, I think, setup0.h in the wxWidgets offered by my VCPKG installation, but I don’t understand how best to resolve this – the comment isn’t exactly specific.

 

Can anybody provide more detailed instructions, please?

 

Many thanks in advance.

Just adding some more detail to my earlier post:

 

I compared the setup.h in my local project to the VCPKG-provided version:

 

C:\vcpkg\buildtrees\wxwidgets\src\v3.3.1-bda38eaf74.clean\include\wx\msw\setup.h

 

And found that the VCPKG version of the file completely lacks the required definition. I’ve now copied the definition into the VCPKG version of the file, but I still get the same build errors in my project.

 

1 – Did I modify the correct file within my VCPKG structure?

 

2 – If the answer to the previous question is “yes”, how do I go about rebuilding the VCPKG-provided wxWidgets, taking into account my changes?

 

Best wishes.

 

Tim

You should rebuild the library with the updated setup.h.

Alternatively you can download the sources and build it yourself.

Thank you.

 

Best wishes.

Sure, I can help.

First, let's make sure I understand your build environment. From the
error message you posted, it looks like you're using MSVC on Windows,
correct?

You also wrote:

When using wxWidgets from vcpkg, you should not have your own setup.h,
but you should be using the one installed by vcpkg.

If, for some reason, you need a customized build of wxWidgets and
still want to use vcpkg mechanisms with your own customizations, that
is also possible by using an "overlay port". However, I would try
using the one provided by vcpkg first to avoid the extra work.

I recently had a new project using wxWidgets from vcpkg:
<https://github.com/LegalizeAdulthood/odeint-example>
There are working builds for Windows, macOS and linux for that:
<https://github.com/LegalizeAdulthood/odeint-example/actions>

In that example, I used vcpkg as a git submodule checked out at the
tag 2025.09.17. (I tend to checkout vcpkg at specific tags because
those are considered "stable" versions.) That gave me wxWidgets 3.3.1.

Hi,

This is now resolved - my employer uses a custom wxWidgets, which was the source of the issue. The solution is so user-specific that there's no point in me sharing it here.

Many thanks to those who tried to help.

Take care and have fun.

Glad you got it sorted out; it is possible to use vcpkg with custom
build configurations. I've done it to work around bugs in existing
ports and it wasn't as difficult as I expected. If you want help
doing that with wxwidgets, let me know.
