Updating a wxWidgets project for Visual Studio 2019

I recently resurrected a dormant code project and went through the process of converting a wxWidgets 3.0 project to wxWidgets 3.1 and updaing from Visual Studio 2010 to Visual Studio 2019.

Include Directories

Here are the things I had to change to make things build and run:

Change “Platform Toolset” to Visual Studio 2019 in General configuration properties.

Change include and library directories from wxWidgets 3.0.2 to 3.1.4 in VC++ Directories and update the include path for modern Visual Studio. The change to $(IncludePath) does a lot of magic things that will save a lot of trouble. Failure to update that will cause common includes like stdafx.h to be missing.

Change include from:


The only code changes I had to make were to remove wxADJUST_MINSIZE anywhere it showed up.


This is for the debug version of the project. Remove the “d” for libraries in the release version (i.e. wxbase31ud_core.lib => wxbase31u_core.lib).

These libraries showed up as missing:


Adding C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\um\x86 to the linker directories fixed this.


Adding C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.20.27508\lib\x86 to the linker directories fixed this.


Adding C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\ucrt\x86 to the linker directories fixed this.


Adding that to the library list fixed it.

I suspected there was something similar to $(IncludePath) I could add to the library paths to make those resolve, but I wasn’t sure. So I tried $(LibraryPath). And it worked. Magic!

So do that instead of adding those individual directories.

Change library path from:

Update all the libraries from wx 3.0 versions to wx 3.1 versions:

wxmsw30ud_core.lib => wxmsw31ud_core.lib
wxbase30ud.lib => wxbase31ud.lib
wxmsw30ud_adv.lib => wxmsw31ud_adv.lib
wxmsw30ud_html.lib => wxmsw31ud_html.lib
wxmsw30ud_xrc.lib => wxmsw31ud_xrc.lib
wxbase30ud_net.lib => wxbase31ud_net.lib
wxbase30ud_xml.lib => wxbase31ud_xml.lib

After these changes I was able to build and run my old project, which was originally written for wxWidgets 2.8 and then ported to wxWidgets 3.0.
