As some file decompression utilities have problems resolving UNIX symlink files, please check whether there are any 0-size files in Adwaita/scalable and/or Adwaita/cursors. If there are, there is a good chance that you are affected by this problem. Delete the whole folder tree and try again, note that the following utilities are known to work correctly: - Latest stable version of 7-zip (version 15.14 at time of writing) - Using the latest tar/xz as provided by MSYS2, by calling 'tar -Jxvh'. Please refer to the following GNOME Live! page for more detailed instructions on building this package with Visual C++: https://live.gnome.org/GTK%2B/Win32/MSVCCompilationOfGTKStack The adwaita-msvc.mak is an NMake Makefile that is meant to be used to generate the index.theme file that is needed for installation of this icon theme package, as well as copying and processing the icon files so that they will be ready for use for GTK+ applications. The required dependencies are as follows: -A working installation of Python 2.7.x+ or 3.x, which could be built from the sources or obtained from the installers from http://www.python.org. For optimal results, you will also need: -The gtk-update-icon-cache tool, which can be found by building the latest GTK+ 2.24.x/3.18.x (or later) package. The tool should be placed in $(PREFIX)\bin. -PNG versions of the SVG symbolic icons are generated in 16x16, 24x24, 32x32, 48x48, 64x64 and 96x96 sizes if the gtk-encode-symbolic-svg tool is found in $(PREFIX)\bin, and the SVG GDK-Pixbuf loader is properly installed, which is obtained by building GDK-Pixbuf and libRSVG. The PNG versions of the symbolic icons are necessary if your app is a GTK-3.x app and you are not intending to ship the SVG GDK-Pixbuf loader nor the libRSVG DLL (which are both required otherwise). Run 'nmake /f adwaita-msvc.mak' to generate the needed index.theme file. PYTHON=xxx can be specified on the command line if your Python interpretor is not in your PATH. Run 'nmake /f adwaita-msvc.mak install' to copy the generated index.theme, as well as all the icon and cursor files into $(PREFIX)\share\icons, and process them if the optional tools are found, so that the icons will be ready for use by GTK+-using applications. A 'clean' target is provided to remove all the generated files-to uninstall the installed icons, simply delete the $(PREFIX)\share\icons\Adwaita folder. Please refer to the README.txt file in $(GLib_src_root)\win32\vs on how to build GLib using your version of Visual Studio. Versions 2008 through 2015 are currently supported.
