CoDExtended — Old Linux & Locked Host Compatibility

A custom compiled & packaged build of CoDExtended, built specifically for older Linux server environments and to bypass the locked/unchangeable startup commands found on certain free or budget hosting panels (such as OptikLink).

This build is based on the original, unmodified CoDExtended source, compiled against older toolchains/libraries (debian_source-style base images) and packaged as iw1x.so so it drops in as a direct replacement for hosts that hardcode LD_PRELOAD="./iw1x.so" in their startup string.

The only source change made in this build is a single cosmetic edit to the SERVERINFO version string, so the server browser / serverinfo output shows who packaged the build:

Cvar_Get("codextended", va("CoDExtended v%d (%s) Build By BO7MEDX", CURRENTBUILD, __DATE__), CVAR_SERVERINFO | CVAR_ROM | CVAR_NORESTART);

No gameplay logic, mod features, or functionality were changed — this is purely a build/version-label change, made transparently in line with GPLv3's requirement to mark modified files.

The Problem This Solves

Many free or budget CoD1 hosting providers (e.g. the OptikLink panel) lock the server's startup command and Docker image, and don't allow you to edit them. A typical locked startup string looks like this:

LD_LIBRARY_PATH="." LD_PRELOAD="./iw1x.so" ./cod_lnxded +exec ServerConf.cfg +set dedicated "2" +set ttycon 0 ...

The Docker image is often something like quay.io/parkervcp/pterodactyl-images:debian_source, which is an older Linux base — meaning a modern build of CoDExtended (normally named codextended.so) will either:

• Not load at all, because the startup command is hardcoded to preload iw1x.so, not codextended.so — and you have no permission to edit the startup line, or
• Fail to run / crash on launch, because the host's base system libraries are too old for a build compiled against a modern toolchain.

This build fixes both issues:

1. It is compiled for older Linux base images (debian_source-style), so it runs without missing-symbol or GLIBC version errors on outdated hosts.
2. It is packaged/renamed as iw1x.so, matching the filename the locked startup command already expects — no panel/startup edits needed.

Internally, the version string shown to players/server browsers (serverinfo) was edited to read Build By BO7MEDX (see License & Attribution below) — this is the only source-level change in this build. The shared object is then renamed to iw1x.so on disk so it matches what locked startup commands expect.

Download & Installation

This repo distributes compiled binaries only (via Releases). No source code is included or modified here — for the source, see the original repository.

Step 1 — Download

Go to the Releases page of this repo and download the latest release archive. It contains two files — both are required:

File	Purpose
iw1x.so	The compiled CoDExtended build itself
libmariadb.so.3	MariaDB client library required by CoDExtended's SQL features — must sit next to iw1x.so

Step 2 — Upload

Upload both files to your CoD1 dedicated server's main directory — the same folder where cod_lnxded lives (your fs_basepath/fs_homepath root). On OptikLink this is usually the root shown in the Files tab.

Step 3 — Verify your startup command

Make sure your startup command (Startup tab on OptikLink, or your launch script elsewhere) references iw1x.so, for example:

LD_LIBRARY_PATH="." LD_PRELOAD="./iw1x.so" ./cod_lnxded +exec ServerConf.cfg +set dedicated "2" +set ttycon 0 +set sv_maxclients "50" +set rconpassword "yourpassword" +set net_ip 0.0.0.0 +set net_port "5243" +set fs_basepath . +set fs_homepath . +map_rotate

If your panel already locks the startup command to ./iw1x.so (like OptikLink does by default), you don't need to change anything — just drop the file in and restart the server.

Step 4 — Restart the server

Restart your CoD1 server from your panel/console. If it loaded correctly, you'll see CoDExtended's normal startup messages in the console log.

Tested Environment

• Docker Image: quay.io/parkervcp/pterodactyl-images:debian_source
• Panel: OptikLink
• Game Server: cod_lnxded (Call of Duty 1)

If you're running a different/older Linux distro and getting GLIBC_2.XX not found or similar errors with the official CoDExtended build, this build is likely the fix you need.
