IRC Client Daemon INSTALL
=========================

This guide will help you to install irccd.

Requirements
------------

Build dependencies:

- C99 and few features from C11 (stdatomics.h, stdnoreturn.h).
- [Bison][] and [Flex][]: for configuration files.
- [CMake][]: the cross platform build utility.

Optional runtime dependencies:

- [OpenSSL][]: Used for SSL connections to IRC servers (recommended).

Basic installation
------------------

This is the quick way to install irccd.

	tar xvzf irccd-x.y.z-tar.xz
	cmake -S irccd-x.y.z -B build
	cmake --build build --target all
	sudo cmake --build build --target install

### Disabling plugins

For every plugin, an option `IRCCD_WITH_PLUGIN_<NAME>` is presented and set to
on by default. Substitute `<NAME>` with the plugin uppercase name (e.g. `ASK`).

	cmake build -DIRCCD_WITH_PLUGIN_ASK=Off

### Systemd service

The systemd service file is installed by default if the machine is running
systemd, it's possible to force the option using `IRCCD_WITH_SYSTEMD` to `On` or
`Off`.

	cmake build -DIRCCD_WITH_SYSTEMD=Off
