# platforms
Charybdis is designed with portability in mind, but does not target older systems nor those of solely academic
interest.
Do note that operating systems are only supported if they are supported by their vendor.
## Tier 1
These platforms are the best supported, and should always work. They are actively tested. If you encounter
problems, please file a bug.
* FreeBSD 10.x and above (i386 and amd64)
* Linux 2.6.x and above with glibc or musl (i386, x86_64, and ARM)
* Mac OS X 10.7 and above
* Windows Vista/Server 2008 and above (x86 or x64)
## Tier 2
These platforms are supported, and most features should work, but this is not guaranteed. If you find any
problems, file a bug, but as these are not regularly tested platforms, a timely resolution may not be
possible.
* DragonflyBSD 4.4 and above (i386)
* Linux with uClibc (i386 or x86_64)
* NetBSD 6.1.x and above (i386, amd64)
* OpenBSD 5.6 and above (i386, amd64)
* Solaris 10 and above (i386)
## Tier 3
These platforms should only be considered weakly supported, as they are either experimental or not actively
tested. These platforms have usually been tested in the past, but they may or may not be in a useful state.
Bugs for tier 3 architectures should have patches attached.
* Solaris 10 and above (sparc64)
* Old operating system versions of tier 2 and above platforms
## Tier 4
Platforms that are tier 4 are not supported at all. They include all platforms not included in tier 3 or
above. Bugs to tier 4 platforms **must** have patches attached or will be rejected, possibly without comment.
# platform specific errata
These are known issues and workarounds for supported platforms.
* **FreeBSD**: if you are compiling with ipv6 you may experience
problems with ipv4 due to the way the socket code is written. To
fix this you must: "sysctl net.inet6.ip6.v6only=0"
* **Solaris**: you may have to set your PATH to include /usr/gnu/bin and /usr/gnu/sbin before /usr/bin
and /usr/sbin. Solaris's default tools don't seem to play nicely with the configure script.

feel free.)
* For ECDHE, OpenSSL 1.0.0 or newer is required. RHEL/Fedora and derivatives like CentOS
will need to compile OpenSSL from source, as ECC/ECDHE-functionality is removed from
the OpenSSL package in these distributions.
* For ECDHE, OpenSSL 1.0.0 or newer is required. Solaris; and RHEL/Fedora and its derivatives such as CentOS
have removed support for ECC/ECDHE. You will need to compile your own OpenSSL on these systems.

* Read the NEWS file for what's new in this release.
* The files, /etc/services, /etc/protocols, and /etc/resolv.conf, SHOULD be
readable by the user running the server in order for ircd to start with
the correct settings. If these files are wrong, charybdis will try to use
127.0.0.1 for a resolver as a last-ditch effort.

* SOLARIS USERS: you may have to set your PATH to include /usr/gnu/bin before /usr/bin. Solaris versions
older than 10 are not supported.
* SUPPORTED PLATFORMS: this code should compile without any warnings on:
* FreeBSD 10
* Gentoo & Gentoo Hardened ~x86/~amd64/~fbsd
* RHEL 6 / 7
* Debian Jessie
* OpenSuSE 11/12
* OpenSolaris 2008.x?
* Solaris 10 sparc.
* Solaris 11 x86
Please let us know if you find otherwise. It may work on other platforms, but this is not guaranteed.
