Building

Windows

Initial Windows Build Setup

Download and Install
Windows 10 Windows SDK:
https://developer.microsoft.com/en-us/windows/downloads/sdk-archive
Note: Windows SDK has to be Windows 10 version, NOT Windows 11
Download and Install
Microsoft Visual C++ Redistributable x64
Microsoft Visual C++ Redistributable x86
https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist
Download and Install
Visual Studio 2022
https://visualstudio.microsoft.com/vs
In Visual Studio Setup, Select the following Individual Components:
- MSVC v143 - VS 2022 C++ x64/x86 Spectre-mitigated libs (Latest)
- C++ ATL for latest v143 build tools with Spectre Mitigations (x86 & x64)
Enable PowerShell script execution
Launch Cmd as Administrator
```
powershell Set-ExecutionPolicy RemoteSigned
```
Perform Initial Build
Launch Cmd as Standard user, NOT Administrator
From V8-Jsi Repo directory:
```
powershell ./localbuild.ps1
```

Windows Build

To build Win32 X64 Debug:

Launch Cmd as Standard user, NOT Administrator
From V8-Jsi Repo Directory:

powershell ./localbuild.ps1 -NoSetup

To build the specific platform and flavor, use appropriate build flags:

powershell ./localbuild.ps1 -NoSetup -Platform x86 -Configuration Release

[EXPERIMENTAL!] Building with WSL2 on Windows 10/11

Enable Windows Subsystem for Linux
Install debian: wsl --install -d Debian
Install PowerShell in the Debian VM
Install minimal dependencies on the Debian VM: sudo apt install lsb-release
Make sure you have at least 15Gb of disk space on the drive where the WSL image lives (usually C:)
Build with pwsh ./localbuild.ps1 -AppPlatform android
If setup is completed succesfully, build incrementally with pwsh ./localbuild.ps1 -AppPlatform android -NoSetup

[EXPERIMENTAL!] Building on macOS

Install PowerShell by running brew install --cask powershell
Build with pwsh ./localbuild.ps1 -AppPlatform mac
If setup is completed succesfully, build incrementally with pwsh ./localbuild.ps1 -AppPlatform mac -NoSetup
Note: there are several test failures on macOS currently

Out-of-sync issues

Until the JSI headers find a more suitable home, they're currently duplicated between the various repos. Code in jsi\jsi should be synchronized with the matching version of JSI from react-native (from https://github.com/facebook/hermes/tree/master/API/jsi/jsi).

Build script patches

To regenerate after manual fix-ups, run:

git diff --output=..\..\..\..\scripts\patch\build.diff --ignore-cr-at-eol from \build\v8\build\.
git diff --output=..\..\..\scripts\patch\src.diff --ignore-cr-at-eol from \build\v8\.
git diff --output=..\..\..\..\..\scripts\patch\zlib.diff --ignore-cr-at-eol from \build\v8\third_party\zlib\.
