Compiling Zandronum with Visual Studio

Prerequisites

Visual Studio

You will require Visual Studio to compile Zandronum. In this guide, Visual Studio 2013 will be used, however it is recommended Visual Studio 2015 is used instead (the instructions are the same).

CMake

Download the latest version of CMake from cmake.org. We will use this to generate the projects.

NASM

http://www.nasm.us/

For VC++ 2015, the latest nasm version is required. Currently, this is Version 2.11.08.

FMOD Ex

The old FMOD Ex links were removed from the FMOD website, so ZDoom has archived them at https://zdoom.org/files/fmod/.

For Zandronum 3.1, version 4.44.64 is recommended (the final release of FMOD Ex.)

Quick Windows link: https://zdoom.org/files/fmod/fmodapi44464win-installer.exe

For Zandronum 3.0, version 4.24.x is required, version 4.24.16 recommended

Quick Windows link: https://zdoom.org/files/fmod/fmodapi42416win32-installer.exe

TortoiseHg

https://tortoisehg.bitbucket.io/download/index.html

Used for downloading the soruce and fetching the Mercurial revision ID when compiling the build.

DirectX SDK

https://wiki.zandronum.com/files/DXSDK_Feb10.exe

Zandronum depends on DirectDraw for software rendering on Windows, so the February 2010 SDK release is required.

OpenGL Header Files

• OpenGL 1.2 and above compatibility profile and extension interfaces: glext.h
• WGL Extension interfaces: wglext.h

Note that you may need to put the glext.h and wglext.h into your C:\Program Files\Microsoft SDKs\Windows\v6.1\includes\gl folder (create it if it doesn't exist). To resolve compiling issues under 'gl_clock.cpp' with _interlockedbittestandset and _interlockedbittestandreset, refer here

OpenSSL

OpenSSL is necessary in order for Zandronum to communicate securely with the account authentication server.

Precompiled binaries for Windows are available from Shining Light Productions. You will want the latest non-light edition of OpenSSL 1.0.2 - the description of the correct package mentions "software developers". You should have a choice between 32-bit and 64-bit versions - you will most likely need the 32-bit version unless you are using CMake and select the 64-bit compiler when generating your build files.

Building OpenSSL

If the above packages do not work, you can compile OpenSSL yourself. This is a lengthy and complicated process, so be sure that the existing binaries of OpenSSL definitely don't work before you try this.

• Perl is necessary to build OpenSSL. If you don't have Perl installed already, install ActiveState Perl.

• NASM executable directory must be in the host system's PATH environment variable.

• Download and decompress the latest source of OpenSSL. In the source directory call

perl Configure VC-WIN32 --prefix=c:\Tools\Util\openssl
ms\do_nasm

• Replace c:\Tools\Util\openssl with the path where you want OpenSSL to be installed. Then, in the same directory, but within a VC++ command prompt, call

nmake -f ms\nt.mak
nmake -f ms\nt.mak test
nmake -f ms\nt.mak install

• If an error message 'WinSock32.h does not exist!' is displayed (or the like), you'll need to add these two lines to your console's temporary environment:

SET INCLUDE=%INCLUDE%;c:\Program Files\Microsoft SDKs\Windows\v7.0\Include\
SET LIB=%LIB%;c:\Program Files\Microsoft SDKs\Windows\v7.0\Lib\

Python

https://www.python.org/downloads/

Version 3.5 or newer is required.

Zandronum Source Code

And of course, you will require the Zandronum source code to build Zandronum! You must clone the source with Mercurial to create a build that is compatible with servers.

In the directory where you want to download the source, right-click on empty space, and go to TortoiseHg → Clone. Enter https://hg.osdn.net/view/zandronum/zandronum-stable as the source.

If you want to clone a specific revision, expand Options, check Clone to revision, and enter the revision you want to clone.

For example, if you wanted to download Zandronum 2.1.2's source, you'd enter ZA_2.1.2.

Optional prerequisites

Logitech G-Series LCD SDK

Only available with the keyboard drivers from Logitech hardware.

Build using Visual Studio 2015 or higher

Generate Projects

Open CMake (cmake-gui) and set the Where is the source code textbox to where you downloaded the Zandronum source code. Set Where to build the binaries to wherever you want the project files to be generated. Click Configure and select what you want to generate projects for.

If it says there was an error, ignore it as we will solve it now. Make sure you set up all prerequisites correctly, and point CMake to the location of any missing paths.

Then click Configure again, and point CMake to missing paths. LIB_EAY and SSL_EAY are OpenSSL libraries. YASM is unneeded as we already have NASM.

Your CMake should look like this

Click Configure again and your CMake should look like the image on the left. Now click Generate. This will generate the project files.

Build Zandronum

Now go to where you generated the project files and open Zandronum.sln.

At the top, there will be a Build menu. Click it and click Build Solution.

Now wait for Zandronum to build. It is a large project and will take time to build.

If you encounter an error, see Troubleshooting below.

Once successfully compiled, zandronum.exe will be in the Debug folder in the project directory. zandronum.pk3 will be in the project directory.

Troubleshooting

'Cr0NpxState' : is not a member of _FLOATING_SAVE_AREA

Just comment out the line that calls this, according to zdoom devs, it is only there to give info and doesn't actually affect the project.

error LNK1281: Unable to generate SAFESEH image

When using VC++ 2015, update to the latest nasm version.

Set `/SAFESEH:NO` by going into the properties of the `zdoom` project and navigating to Configuration Properties → Linker → Advanced and changing Image Has Safe Exception Handlers to No (/SAFESEH:NO).
