Building wxGTK port with Win32 MSys2 GDK backend

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

1. Open MSys2 MinGW Prompt (These steps were tested on MinGW64; but, should work under MinGW32)
2. Use the cd command to change directory to the wxWidgets top folder.
3. Create the "build-${MSYSTEM_CARCH}-gtk3-static" folder to build the static libraries

        mkdir -p build-${MSYSTEM_CARCH}-gtk3-static

4. 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 ..

5. clean the wxGTK static libraries

        cd build-${MSYSTEM_CARCH}-gtk3-static && make clean && cd ..

6. make the wxGTK static libraries

        cd build-${MSYSTEM_CARCH}-gtk3-static && make && cd ..

C. Build and run the minimal static sample

1. Clean the minimal sample

        cd build-${MSYSTEM_CARCH}-gtk3-static/samples/minimal && make clean && cd ../../..

2. Build the minimal sample

        cd build-${MSYSTEM_CARCH}-gtk3-static/samples/minimal && make && cd ../../..

3. Run the minimal sample

        ./build-${MSYSTEM_CARCH}-gtk3-static/samples/minimal/minimal.exe

D. Build most of the static samples

1. Clean most of the static samples

        cd build-${MSYSTEM_CARCH}-gtk3-static/samples && make clean && cd ../..

2. Build most of the static samples

        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 ../..
