Cross-Compiling a Multithreaded MT5 DLL on Linux with MinGW
Summary
The article presents a proof of concept for developing a C++ shared library on Linux that can be consumed by MQL5 and run in MetaTrader 5 on Windows. It explains the roles of Wine, which runs Windows applications in a Linux environment, and MinGW, which cross-compiles Windows binaries. It compares MinGW builds using POSIX pthreads and Win32 threading, outlines the setup and DLL integration workflow, and describes testing the resulting program on Linux through Wine and on a Windows virtual machine.
A small benchmark compares single-threaded and multithreaded summation across the two threading models and environments. The reported timings are close in this specific workload, so they do not establish a general performance winner. The author notes that broader comparisons depend on synchronization primitives, thread-local behavior, and problem choice. The practical contribution is a cross-platform development workflow and a working example, rather than a trading strategy or evidence about market performance.
Key ideas
- MinGW can cross-compile C++ code on Linux into Windows DLLs for use with MetaTrader 5.
- Wine provides a compatibility layer for running Windows applications on Linux.
- The article compares MinGW POSIX and Win32 threading implementations and cautions against mixing threading APIs casually.
- A proof-of-concept DLL is consumed by MQL5 and tested on Linux through Wine and on Windows.
- The benchmark is limited to a summation workload and cannot establish a universal threading advantage.
