Currently, webp-viewer does not support native Windows builds with Microsoft Visual Studio. However, it can be built on Windows systems with MSYS2. MSYS2 provides some typical GNU / Linux tools on Windows operating systems. Those can be used to build webp-viewer.
First, download the MSYS2 installer from https://www.msys2.org/#installation and run it. After that is done, open "MSYS2 MinGW x64" from the start menu. This will open a command prompt window. All following steps are done there.
If you haven't done it yet, update any existing base packages by typing
pacman -Syuinto the prompt, then press enter.
To build the webp-viewer from source you need a C++ compiler, CMake, the Ninja build system, the GLFW library and the libwebp library. pkg-config is required to make it easier to find compiler options for the installed libraries. Additionally, the program uses Catch (C++ Automated Test Cases in Headers) to perform some tests.
It also helps to have Git, a distributed version control system, on your build system to get the latest source code directly from the Git repository.
All of that can usually be installed be typing
pacman -S git mingw-w64-x86_64-catch mingw-w64-x86_64-cmake mingw-w64-x86_64-gcc mingw-w64-x86_64-glfw mingw-w64-x86_64-libwebp mingw-w64-x86_64-ninja mingw-w64-x86_64-pkg-configinto the MSYS2 command prompt.
Get the source directly from Git by cloning the Git repository and change to the directory after the repository is completely cloned:
git clone https://github.com/striezel/webp-viewer.git
cd webp-viewerThat's it, you should now have the current source code on your machine.
The build process is relatively easy, because CMake does all the preparations. Starting in the root directory of the source, you can do the following steps:
mkdir build
cd build
cmake ../
cmake --build . -j4It may take a while to build.
The executable will be located at webp-viewer/webp-viewer.exe inside the
build directory.
