mql-compiler

Compile MQL4 and MQL5 on Linux without booting a goddamn Windows box. One command starts MetaQuotes’ own MetaEditor inside a Wine container, compiles your .mq4 and .mq5 files, writes .ex4 and .ex5 right next to them, and hands back every error as JSON Lines your scripts and agents can parse. Humans get --text.

No Windows, no MetaTrader terminal running, no broker account. The image carries Wine and one Bash script and not a single MetaQuotes byte: the first run downloads the MT4 and MT5 installers, checks their MetaQuotes signature and caches the toolchain in a Docker volume.

Quick start

Docker must be running on an x86-64 (amd64) machine. There is no ARM image.

curl -fsSL https://raw.githubusercontent.com/psyb0t/docker-mql-compiler/master/install.sh \
  | bash

# compile the sources under the current directory
mql-compiler --text .

The first compile installs only the MT4 or MT5 toolchain your sources need, in about a minute and a half. Later runs take seconds. Exit 0 means every source compiled, 1 means at least one failed, and 2 means bad arguments or a failed setup.

Agents get the same facts from the mql-compiler skill, published to ClawHub with every release. The source is on GitHub, and the image is psyb0t/mql-compiler on Docker Hub.
