Compile SMA to AMXX – Best Online Compilers & Tools

Last updated: May 8, 2026

Compiling SMA to AMXX is the required step before any AMX Mod X plugin can run on a CS 1.6 server. A .sma file is the Pawn source code – the human-readable script. An .amxx file is the compiled binary the server actually loads. This page lists every working AMXX compiler option available: online web compilers, the official offline compiler for Windows and Linux, and ReAPI for modern servers.

Online AMXX web compilers

Online AMXX compilers let you compile SMA to AMXX directly in a browser with no local installation. Upload your .sma file, select the AMXX version matching your server, and download the compiled .amxx binary. All tools below are free and publicly available.

Compiler	URL	Versions supported	Custom .inc upload	Notes
IceGame AMXX Compiler	amx.icegame.ro	1.7.6, 1.8.0, 1.8.1, 1.8.2, 1.8.3, 1.9.0, 1.10.0	Yes	Most versions, custom include upload, 16 languages, fast
AMXModX.org Official	amxmodx.org/webcompiler.cgi	Latest stable	No	Official tool, stable but limited include support
WorldCS Compiler	amx.worldcs.ro	1.8.2, 1.8.3	Yes	Simple interface, custom include upload supported
NGZ.RO Compiler	amx.ngz.ro	1.8.2, 1.8.3, 1.9.0, 1.10	Yes	Runs on dedicated Linux environment, matches live server compilation
AMXX.pl Compiler	amxx.pl/kompilator	1.8.1	No	Polish community, 4M+ compiles, older version only

If your plugin uses custom includes (Zombie Plague, Jailbreak, Warcraft 3, ReAPI, and similar mods require external .inc files), use IceGame, WorldCS, or NGZ.RO – these three support uploading custom includes before compilation. The official amxmodx.org compiler and AGHL.RU do not support custom include upload, so plugins with non-standard dependencies will fail on those.

Offline compiler – Windows and Linux

The offline AMXX compiler is included inside the AMX Mod X package itself. It is the most reliable method for compiling plugins with complex include dependencies and gives you full control over the compilation environment. Download the full AMX Mod X package from the official source:

amxmodx.org/downloads-new.php – official AMX Mod X downloads page (Windows and Linux builds)

After installing, the compiler is located at:

addons/amxmodx/scripting/amxxpc.exe  (Windows)
addons/amxmodx/scripting/amxxpc      (Linux)

Place your .sma file in the scripting/ folder. All standard .inc files are in scripting/include/. Custom includes for specific mods go in that same include folder.

Windows – three ways to compile

Method	Steps
Drag and drop	Drag your .sma file onto compile.exe. The compiled .amxx appears in the scripting/compiled/ folder.
Compile all	Double-click compile.exe with no file – compiles every .sma in the scripting folder at once.
Command line	Open cmd, navigate to the scripting folder, run: amxxpc.exe myplugin.sma

Linux – command line

cd addons/amxmodx/scripting
./amxxpc myplugin.sma

Or compile all plugins at once:

sh compile.sh

The compiled .amxx file goes into scripting/compiled/. Copy it to addons/amxmodx/plugins/ and add the plugin name to addons/amxmodx/configs/plugins.ini to activate it.

ReAPI for ReHLDS servers

ReAPI is an AMX Mod X module that provides extended APIs for servers running ReHLDS and ReGameDLL instead of the standard HLDS engine. If your server runs ReHLDS, plugins that use ReAPI functions must be compiled with the ReAPI .inc files available – standard AMX Mod X includes do not contain them.

ReAPI source and releases: github.com/rehlds/ReAPI

To compile a plugin that uses ReAPI with an online compiler, upload reapi.inc as a custom include file before compiling. IceGame, WorldCS, and NGZ.RO all support this. With the offline compiler, place reapi.inc in your scripting/include/ folder and compile normally.

For more on setting up a server that runs ReHLDS, see the ReHLDS server setup guide.

AMXX version compatibility

The AMXX version you compile against must match the version installed on your server. Compiling with 1.9.0 and running AMXX 1.8.2 on the server will produce “Plugin failed to load” errors. Check your server’s AMXX version in the console with amxx version.

AMXX version	Use case
1.10.0	Modern Linux servers with ReHLDS, latest features
1.9.0	Modern servers, widely used, ReHLDS support
1.8.2	Most stable legacy version, used on the majority of active public servers
1.8.3	Transition version between old and new builds
1.8.0 / 1.8.1	Older servers requiring backward compatibility
1.7.6	Very old or specialized server builds only

When in doubt, 1.8.2 is the safest choice for legacy CS 1.6 public servers. If you manage a modern server and want the latest features, compile with 1.9.0 or 1.10.0.

Custom include files

Standard AMXX plugins only need the default include files that come with AMX Mod X (amxmodx.inc, amxmisc.inc, cstrike.inc, etc). Plugins for specific mods need additional .inc files that are not bundled with AMXX. These must be provided to the compiler manually.

Mod / plugin type	Required custom includes	Where to get them
Zombie Plague	zombieplague.inc	Inside the Zombie Plague plugin package from AlliedModders
ReAPI plugins	reapi.inc	github.com/rehlds/ReAPI
Jailbreak	jailbreak.inc	Inside the Jailbreak mod package
HamSandwich	Bundled with AMXX 1.8.2+	Already in the standard include folder
FakeMeta	Bundled with AMXX	Already in the standard include folder

With online compilers that support custom include upload (IceGame, WorldCS, NGZ.RO): upload the required .inc files before clicking compile. With the offline compiler: place all custom .inc files into addons/amxmodx/scripting/include/.

Common compile errors

Error message	Cause	Fix
fatal error 100: cannot read from file: "zombieplague"	Missing custom include file	Upload zombieplague.inc before compiling, or add it to your local include folder
error 013: no entry point (no public functions)	The file is empty or contains no valid plugin entry point	Check the .sma file has at least one public plugin_init() function
Plugin failed to load on server	Compiled with wrong AMXX version	Recompile using the exact version your server runs – check with amxx version in console
error 017: undefined symbol	Function or variable not defined – usually a missing include	Find which include defines that symbol and add it to the compiler
You must upload a valid file	Wrong file format uploaded to web compiler	Make sure the file has a .sma extension and is plain text, not a compiled binary

If none of the online compilers resolve your include errors, switch to the offline compiler where you have full control over the include folder. The AlliedModders wiki has the complete compilation guide at wiki.alliedmods.net.
