GTK+ widget toolkit has multiple GDK backends and one of them is Win32. It is a wrapper around Windows API.
These notes don't consider building wxGTK with X11 backend under Windows.
The MSys2 website is http://www.msys2.org/
These building steps are NOT the normal way to build MSys2 MinGW packages. But, they are a way the wxWidgets developers can test that wxWidgets can build the wxGTK/Win32 libraries under MSys2 MinGW.
For the MSys2 way please see https://github.com/msys2/MINGW-packages and https://www.msys2.org/wiki/Creating-Packages/
Building steps:
A. Install the MSys2 mingw packages needed to build wxGTK/Win32 using the configure/make build method. From the MSys2 MinGW prompt:
pacman -S --needed --noconfirm make pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-libjpeg-turbo pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-libpng pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-libtiff pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-gcc pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-pkg-config ## gtk3 can take a long time to update/find fonts pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-gtk3
Packages that are needed but are normally installed already.
pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-gcc-libs pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-expat pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-xz pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-zlib pacman -S --needed --noconfirm ${MINGW_PACKAGE_PREFIX}-gdk-pixbuf2
B. Build the wxGTK/Win32 static library
mkdir -p build-${MSYSTEM_CARCH}-gtk3-static
Configure wxWidgets Option "--disable-precomp-headers" is NOT needed. It is being used to test for compile issues.
Remove configure option "--disable-wxdib" to set wxUSE_WXDIB to 1. The directions docs/msw/gtk.txt results in wxUSE_WXDIB set to 1.
cd build-${MSYSTEM_CARCH}-gtk3-static && \ ../configure --with-gtk=3 \ --disable-wxdib \ --disable-shared \ --disable-precomp-headers \ && cd ..
cd build-${MSYSTEM_CARCH}-gtk3-static && make clean && cd ..
cd build-${MSYSTEM_CARCH}-gtk3-static && make && cd ..
C. Build and run the minimal static sample
cd build-${MSYSTEM_CARCH}-gtk3-static/samples/minimal && make clean && cd ../../..
cd build-${MSYSTEM_CARCH}-gtk3-static/samples/minimal && make && cd ../../..
./build-${MSYSTEM_CARCH}-gtk3-static/samples/minimal/minimal.exe
D. Build most of the static samples
cd build-${MSYSTEM_CARCH}-gtk3-static/samples && make clean && cd ../..
cd build-${MSYSTEM_CARCH}-gtk3-static/samples && make && cd ../..
E. Run the drawing static sample
cd samples/drawing && ../../build-${MSYSTEM_CARCH}-gtk3-static/samples/drawing/drawing.exe && cd ../..
F. Run the splash static sample
cd samples/splash && ../../build-${MSYSTEM_CARCH}-gtk3-static/samples/splash/splash.exe && cd ../..
G. Run the widgets static sample
cd samples/widgets && ../../build-${MSYSTEM_CARCH}-gtk3-static/samples/widgets/widgets.exe && cd ../..
H. Run the toolbar static sample
cd samples/toolbar && ../../build-${MSYSTEM_CARCH}-gtk3-static/samples/toolbar/toolbar.exe && cd ../..
I. Run the image static sample
cd samples/image && ../../build-${MSYSTEM_CARCH}-gtk3-static/samples/image/image.exe && cd ../..
