A module for Garry's Mod that mitigates exploits on the Source engine.

Based on these plugins from AzuiSleet:

serverplugin_serversecure

serverplugin_serversecure2

serversecure3

The only supported compilation platform for this project on Windows is Visual Studio 2017 on release mode. However, it's possible it'll work with Visual Studio 2015, Visual Studio 2019 and Visual Studio 2022 because of the unified runtime.

On Linux, everything should work fine as is, on release mode.

For macOS, any Xcode (using the GCC compiler) version MIGHT work as long as the Mac OSX 10.7 SDK is used, on release mode.

These restrictions are not random; they exist because of ABI compatibility reasons.

If stuff starts erroring or fails to work, be sure to check the correct line endings (\n and such) are present in the files for each OS.

This project requires garrysmod_common, a framework to facilitate the creation of compilations files (Visual Studio, make, XCode, etc). Simply set the environment variable 'GARRYSMOD_COMMON' or the premake option 'gmcommon' to the path of your local copy of garrysmod_common.

We also use SourceSDK2013. The links to SourceSDK2013 point to my own fork of VALVe's repo and for good reason: Garry's Mod has lots of backwards incompatible changes to interfaces and it's much smaller, being perfect for automated build systems like Azure Pipelines (which is used for this project).
