Compiling the SDK

Step 1:

• Install Visual Studio 2003, Visual Studio 2005, or Visual C++ 2005 Express Edition.
  
• Install Microsoft Platform SDK for Windows 2003 (NOT Vista). This step is not required if you're using the full version of Visual Studio, as the PSDK is included with VS.
  
• Install Quake 4 SDK.
  
  Step 2:
  
• Open q4sdk.sln
  
• If asked to convert the projects, say yes.
  
• Ignore any warnings about source control.
  
  Step 3:
  
• Repeat the following for all 3 projects (Game, idlib, MPGame), setting the configuration selector to 'All Configurations':
  
  1. Right click on the project name and choose 'Properties'.
     
  2. Goto 'Configuration Properties -> C/C++ -> General' and in the 'Additional Include Directories' field put ' "<path-to-PSDK>\include" ' (include the ""). Replace the <path-to-PSDK> to point to wherever you installed the PSDK (usually C:\Program Files\PSDK\...). Use the ... button to help find the appropriate folder quickly.
     
  Step 4:
  
• Repeat the following for Game and MPGame (NOT idlib), setting the configuration selector to 'All Configurations':
  
  1. Right click on the project name and choose 'Properties'.
     
  2. Goto 'Configuration Properties -> Linker -> General' and in the 'Additional Library Directories' field put ' "<path-to-PSDK>\lib" ' (include the ""). Replace the <path-to-PSDK> to point to wherever you installed the PSDK (usually C:\Program Files\PSDK\...). Use the ... button to help find the appropriate folder quickly.
     
  3. Goto 'Configuration Properties -> Linker -> Input' and in the 'Additional Dependencies' field add ' Advapi32.lib' onto the end of the list (include the space).
     
  Step 5:
  
• Left click once on the 'Game' project (to highlight it).
  
• Goto the 'Build' menu and select 'Clean Solution'.
  
• Goto the 'Build' menu and select 'Build Solution'.
  

Well Done. You should have no errors and a nice clean 'Gamex86.dll' sitting in the SDK output folder somewhere. You can now start editing the SDK to try and modify the game.

Good stuff
