New article Develop a Proof-of-Concept DLL with C++ multi-threading support for MetaTrader 5 on Linux has been published:
We will begin the journey to explore the steps and workflow on how to base development for MetaTrader 5 platform solely on Linux system in which the final product works seamlessly on both Windows and Linux system. We will get to know Wine, and Mingw; both are the essential tools to make cross-platform development works. Especially Mingw for its threading implementations (POSIX, and Win32) that we need to consider in choosing which one to go with. We then build a proof-of-concept DLL and consume it in MQL5 code, finally compare the performance of both threading implementations. All for your foundation to expand further on your own. You should be comfortable building MT related tools on Linux after reading this article.
Linux has a vibrant development ecosystem and a good ergonomic for software development.
It is attractive for those who enjoy working with command line, ease of installation of application via package manager, OS that is not a blackbox but still pulls you to dig deep learning about its internals, configurable for almost all of the sub-systems, essential development tools that are ready to be used out-of-box, flexible and streamlined environment suitable for software development, etc.
It is available ranging from end-user PC desktop to cloud solution e.g. VPS, or cloud service providers like AWS, Google Cloud.
So, I strongly believe there are some developers here that want to stick to their OS of choice but still want to be able to develop & deliver products to Windows users. Of course, products must work the same seamlessly across platform.
Normally MetaTrader 5 developers just use MQL5 programming language to develop their indicators/experts or related products then publish on the market to end-users without any concern about which OS to base on. They can just rely on MT5's IDE to take care of compiling and building .EX5 executable before delivery (provided that they know how to launch MetaTrader 5 on Linux).
But when developers need to involve developing a custom solution as a shared library (DLL) to further expand and provide additional services that MQL5 programming language alone cannot offer, then they will have to spend more time and effort in seeking for solution of cross-compilation, discovery of gotchas and best practices, getting familiar with the tools, etc.
