OCaml distribution for Haxe compilation

ocamhaxe

OCaml distribution for Haxe compilation

Install

Download the Latest Release then simply run config.bat to have it setup on your system.

Build

If you have cloned the repository, you need to run the Build.exe script in /build to rebuild the ocamhaxe distribution. This requires Cygwin 64 bits + Dumpbin.exe windows utility (part of Visual Studio)

Required Cygwin64 packages are:

• wget
• m4
• patch
• unzip
• perl
• perl-IPC-System-Simple
• libpcre2-devel
• mingw64-x86_64-gcc-core
• mingw64-x86_64-zlib
• mingw64-x86_64-pcre
• mingw64-x86_64-pcre2

(or for 32 bits):

• mingw[64]-i686-gcc-core
• mingw[64]-i686-zlib
• mingw[64]-i686-pcre

Troubleshoot:

• You need to run Build.exe from the command line (cmd) to watch for errors
  • If you have Haxe installed, you can also run haxe --interp --main Build from the haxe folder
• In some cases there is an error about prims.c not compiling when building the ocaml compiler. It requires having git for Cygwin installed (prevents windows newline issues). Also make sure that your system PATH has Cygwin at the highest priority to prevent clashes.
• If you get Access Denied when runnning Build.exe, checkout again the ocamhaxe repository using Git For Windows. Note that rebuilding the .exe files without deleting them might still cause this error.
• Download and unzip mingw64-uv mingw64-mbedtls to your Cygwin install folder, from the link provided in haxe/config.json/mingwPackages
• If there's a process failure related to dumpbin.exe, you can either:
  1. find it in your Visual Studio installation (somewhere in the depths of C:\Program Files (x86)\Microsoft Visual Studio) and add its containing directory to your PATH, or
  2. run ocamhaxe in a developer command prompt from within Visual Studio.
• If "Processing actions" takes a long time, try disabling Windows Defender realtime protection (MsMpEng).

About

There are two distinct scripts:

• haxe/Build.hx will build an ocamhaxe repo from scratch, that can be zip'ed and distributed to users as-it. It should contain everything needed to compile & run haxe and its libraries, without any additional requirement

• haxe/Config.hx will setup the computer (env vars etc.) on the client computer that has downloaded the ocamhaxe distribution. It is triggered by config.bat so runs from the toplevel directory.

• both are precompiled using hxcpp so they can get run on a system even if no haxe is available.

• both are referencing haxe/config.json which contains cygwin tools / opam libs to install etc. mostly used for the build process or to check in Config if the cygwin already installed on the computer have all the necessary tools/libs
