About Inspircd
From the project's README at github.com/inspircd/inspircd. Lightly cleaned for readability; for the full source see the upstream repo.
The branch contains the latest unstable development code. If you are running a server then you probably want to use a v4 release for now. You can obtain this from the releases page or by running if you are installing from Git. About
InspIRCd is a modular C++ Internet Relay Chat (IRC) server for UNIX-like and Windows systems. Supported Platforms
InspIRCd is supported on the following platforms: Most recent BSD variants using the Clang 10+ or GCC 10+ compilers, CMake 3.21+, and either Ninja (recommended) or Make. Most recent Linux distributions using the Clang 10+ or GCC 10+ compilers, CMake 3.21+, and either Ninja (recommended) or Make. The most recent three major releases of macOS using the AppleClang 12, Clang 10+, or GCC 10+ compilers, CMake 3.21+, and either Ninja (recommended) or Make. Windows 10 April 2018 Update or newer using the MSVC 19.29+ (Visual Studio 16.10 2019) compiler, CMake 3.21+, and either Ninja (recommended) or MSBuild.
Other platforms and toolchains may also work but are not officially supported by the InspIRCd team. Generally speaking if you are using a reasonably modern UNIX-like system you should be able to build InspIRCd on it. If you can not and you wish to submit a patch we are happy to accept it as long as it is not extremely large.
