Compilation guide for Windows (using Visual Studio and vcpkg)

This guide contains steps required to allow compilation of Cataclysm-BN on Windows using Visual Studio and vcpkg.

Steps from current guide were tested on Windows 10 (64 bit), Visual Studio 2019 (64 bit) and vcpkg, but should as well work with slight modifications for other versions of Windows and Visual Studio.

Prerequisites:

  • Computer with modern Windows operating system installed (Windows 10, Windows 8.1 or Windows 7);
  • NTFS partition with ~15 Gb free space (~10 Gb for Visual Studio, ~1 Gb for vcpkg installation, ~3 Gb for repository and ~1 Gb for build cache);
  • Git for Windows (installer can be downloaded from Git homepage);
  • Visual Studio 2019 (or 2015 Visual Studio Update 3 and above);
    • Note: If you are using Visual Studio 2022, you must install the Visual Studio 2019 compilers to work around a vcpkg bug. In the Visual Studio Installer, select the 'Individual components' tab and search for / select the component that looks like 'MSVC v142 - VS 2019 C++ x64/x86 Build Tools'. See microsoft/vcpkg#22287.
  • Latest version of vcpkg (see instructions on vcpkg homepage).

Note: Windows XP is unsupported!

Installation and configuration:

  1. Install Visual Studio (installer can be downloaded from Visual Studio homepage).
  • Select the "Desktop development with C++" and "Game development with C++" workloads.

  1. Install Git for Windows (installer can be downloaded from Git homepage).

  2. Install and configure latest vcpkg:

WARNING: It is important that, wherever you decide to clone this repo, the path does not include whitespace. That is, C:/dev/vcpkg is acceptable, but C:/dev test/vcpkg is not.

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg integrate install

Cloning and compilation:

  1. Clone Cataclysm-BN repository with following command line:

Note: This will download the entire CBN repository; about three gigs of data. If you're just testing you should probably add --depth=1.

git clone https://github.com/cataclysmbnteam/Cataclysm-BN.git
cd Cataclysm-BN

  1. Open the provided solution (msvc-full-features\Cataclysm-vcpkg-static.sln) in Visual Studio, select configuration (Release or Debug) and platform (x64 or x86) and build it. All necessary dependencies will be built and cached for future use by vcpkg automatically.

  2. Open the Build > Configuration Manager menu and adjust Active solution configuration and Active solution platform to match your intended target.

This will configure Visual Studio to compile the release version, with support for Sound, Tiles, and Localization (note, however, that language files themselves are not automatically compiled; this will be done later).

  1. Start the build process by selecting either Build > Build Solution or Build > Build > 1 Cataclysm-vcpkg-static. The process may take a long period of time, so you'd better prepare a cup of coffee and some books in front of your computer :) The first build of each architecture will also download and install dependencies through vcpkg, which can take an especially long time.

  2. If you need localization support, execute the bash script lang/compile_mo.sh inside Git Bash GUI just like on a UNIX-like system. This will compile the language files that were not automatically compiled in step 2 above.

Running from Visual Studio and debugging

Ensure that the Cataclysm project (Cataclysm-vcpkg-static) is the selected startup project, configure the working directory in the project settings to $(ProjectDir).., and then press the debug button (or use the appropriate shortcut, e.g. F5).

If you discover that after pressing the debug button in Visual Studio, Cataclysm just exits after launch with return code 1, that is because of the wrong working directory.

When debugging, it is not strictly necessary to use a Debug build. Release builds run significantly faster, can still be run in the debugger, and most of the time will have most of the information you need. If optimizations of Release build interfere with debugging, you can disable them on a file-by-file basis by adding

#pragma optimize("", off)

line at the top of the file.

Running unit tests

Ensure that the Cataclysm test project (Cataclysm-test-vcpkg-static) is the selected startup project, configure the working directory in the project settings to $(ProjectDir).., and then press the debug button (or use the appropriate shortcut, e.g. F5). This will run all of the unit tests. Additional command line arguments may be configured in the project's command line arguments setting, or if you are using a compatible unit test runner (e.g. Resharper) you can run or debug individual tests from the unit test sessions.

Make a distribution

There is a batch script in msvc-full-features folder distribute.bat. It will create a sub folder distribution and copy all required files(eg. data/, Cataclysm.exe and dlls) into that folder. Then you can zip it and share the archive on the Internet.
