electron for riscv64

This repo is a fork of electron with riscv64 support added.

Releases are published in https://github.com/riscv-forks/electron-riscv-releases

Repo Organization

Branches with riscv64 support have a suffix of -riscv. e.g. main-riscv, 28-x-y-riscv, v29.1.1-riscv.

Necessary Toolchains for cross-compilation

• Debian riscv sysroot

Note: To build the sysroot, please checkout chromium source code at 1273786fb3efd and apply the sysroot.patch. The sysroot creator patch is not maintained in electron patches.

Build Instruction

This repo supports both building in RISC-V environment and cross-compiling from a x86-64 host.

Cross-Compile

Host Environment

Debian bookworm.

Getting the Source

First, install depot_tools and add it to PATH.

Then, get the source code:

$ mkdir electron && cd electron
$ gclient config --name "src/electron" --unmanaged https://github.com/riscv-forks/electron@BRANCH_NAME_HERE
$ gclient sync --with_branch_heads --with_tags

Sysroot Preparation

Please download the latest debian sysroot from GitHub Releases and put it at build/linux/debian_trixie_riscv64-sysroot:

rm -rf build/linux/debian_trixie_riscv64-sysroot
mkdir build/linux/debian_trixie_riscv64-sysroot
tar xf "$YOUR_DOWNLOADED_SYSROOT_FILE" --directory=build/linux/debian_trixie_riscv64-sysroot

Building from Source

Run GN:

./buildtools/linux64/gn gen out/Release-riscv64 --args="import(\"//electron/build/args/release.gn\") target_cpu = \"riscv64\""

Run ninja:

autoninja -C out/Release-riscv64/ electron

Generate Dist Zip:

electron/script/strip-binaries.py -d out/Release-riscv64 --target-cpu riscv64
autoninja -C out/Release-riscv64 electron:electron_dist_zip

Build on RISC-V

Arch Linux riscv64 is building electron on riscv64.

The patch of Arch Linux's PKGBUILD is available here for reference: https://github.com/felixonmars/archriscv-packages/blob/master/electron28/riscv64.patch

TODOs

• Set up CI to automatically create riscv branches from upstream tags.
• Cover more tests in Chromium CI.
