Neutralino.js port attempt

SamuraiCrow · August 27, 2023, 2:15am

The following quote from the .NET thread got this started.

In my first attempt at porting Neutralino, I attempted to target WebKit_GTK and GTK3 using the existing build infrastructure but BuildZri v1.0.0 didn’t have a clue how to build on Haiku. I tried hotwiring it to think that it was just a flavor of Linux but it wasn’t close enough. The build failed.

The following dependencies are assumed on the Linux build:

xrandr
xcb
WebKit2GTK+ v4

It appears there will be no easy shortcuts on this build. I (or someone else) will have to go through the Python3 build script. If anyone else is interested, the repo is at:

The build instructions are at:

It is necessary to add Haiku; compiler and cpu architecture in BuildZri code:

#!/usr/bin/env python3

import sys
import os
import subprocess
import platform
import json
import glob
import argparse

parser = argparse.ArgumentParser()
parser.add_argument('--verbose', action='store_true')
parser.add_argument('--target_arch', choices=['x64', 'arm64', 'armhf'])
args = parser.parse_args()

C = {}

BZ_VERSION = '1.0.0'
BZ_CONFIG_FILE = 'buildzri.config.json'
BZ_OS = platform.system().lower()

Neutralinojs uses libraries with Haiku support:

I know. That is what I was concerned about. Having to set up a from-scratch implementation of the build-script, I might as well write it as a HaikuPorter recipe and forget their build script. I’ll still refer to theirs though.

Update:

I just realized that there is a libxcb_devel package in HaikuPorts along with its dependencies. That got a little farther with the fake Linux build. Unfortunately libxrandr is not ported to Haiku so that still didn’t do it. I’ll try to keep tinkering.

libxrandr-devel contains header file and library, it’s an X11 extension, probably depends on Xlibe to work:

It would seem that XLibE doesn’t support that extension at this time.

Part of the Infoware code is used, which uses Xrandr for display:

It would modify displays_x11.cpp file for Haiku or create a file for app_server!
