Document existing ARM64 build support for Raspberry Pi 5 #932

Copilot · 2025-12-20T08:05:12Z

ARM64 builds for Raspberry Pi 5 were already being generated via electron-builder cross-compilation but were undocumented. Users requesting ARM64 support were unaware these artifacts existed in releases.

Changes

Documentation: Added platform support matrix to README showing ARM64 availability for Linux (AppImage, Deb)
Build logging: Added console output showing target architectures during packaging (simplified to show x64 and arm64 only)
Code clarity: Added inline comments in package.ts marking ARM64 flags for Raspberry Pi 5

Build Output

When yarn package linux runs, it now logs:

Building Linux packages for architectures: x64, arm64 (Raspberry Pi 5)
Building AppImage for architectures: x64, arm64
Building deb for architectures: x64, arm64

Generates release artifacts:

MQTT-Explorer<version>-arm64.AppImage
MQTT-Explorer_<version>_arm64.deb

No changes to build configuration or CI workflow - ARM64 cross-compilation was already functional.

- Add detailed comments in package.ts clarifying ARM64 support for Raspberry Pi 5 - Add console logging to show which architectures are being built - Update README with platform support section mentioning ARM64/Raspberry Pi 5 - Clarify that ARM64 builds are generated for both AppImage and Deb packages Co-authored-by: thomasnordquist <[email protected]>

package.ts

+  if (options.arm64) architectures.push('arm64')
+  if (options.armv7l) architectures.push('armv7l')
+  if (options.ia32) architectures.push('ia32')


@copilot remove ia32 and armv7l

Done. Removed ia32 and armv7l from the architecture logging. The logging now only shows x64 and arm64. (d4a7d3d)

Pull request overview

This PR documents the existing ARM64 build support for Raspberry Pi 5 that was already configured in electron-builder but not documented. The changes add a platform support matrix to the README and improve build logging to show which architectures are being targeted.

File	Description
Readme.md	Added new "Platform Support" section documenting Windows, macOS, and Linux architecture support including ARM64 for Raspberry Pi 5
package.ts	Added comments explaining ARM64 is for Raspberry Pi 5, added console logging to show architectures being built for each package format

package.ts

+  // Log architectures being built
+  const architectures = []
+  if (options.x64) architectures.push('x64')
+  if (options.arm64) architectures.push('arm64')


The logging code only captures x64 and arm64 architectures, but the actual build configurations include armv7l as well. The log output will be incomplete and won't show that armv7l is being built for AppImage and Deb packages. Consider adding armv7l to the architectures array to provide accurate build information.

Suggested change

if (options.arm64) architectures.push('arm64')

if (options.arm64) architectures.push('arm64')

if (options.armv7l) architectures.push('armv7l')

Readme.md

+- **Windows**: x64
+- **macOS**: x64 (Intel) and ARM64 (Apple Silicon)
+- **Linux**: x64, ARM64 (Raspberry Pi 5), and ARMv7l (Raspberry Pi 4 and older)
+  - Available formats: AppImage, Deb, Snap


The README states that Snap format is available for all Linux architectures (x64, ARM64, ARMv7l), but the linuxSnap configuration in package.ts explicitly has arm64: false and armv7l: false. The Snap package is only built for x64. The README should clarify which formats are available for which architectures, for example: "AppImage and Deb: x64, ARM64, ARMv7l; Snap: x64 only".

Suggested change

- Available formats: AppImage, Deb, Snap

- Available formats: AppImage (x64, ARM64, ARMv7l), Deb (x64, ARM64, ARMv7l), Snap (x64 only)

package.ts

      await buildWithOptions(winAppx, { platform: 'win', package: 'appx' })
      break
    case 'linux':
+      console.log('Building Linux packages for architectures: x64, arm64 (Raspberry Pi 5), armv7l')


This console.log statement claims to build for "x64, arm64 (Raspberry Pi 5), armv7l", but when the actual buildWithOptions calls execute, the new logging code (lines 113-117) will only show x64 and arm64. This creates inconsistent and potentially confusing output. Either remove this summary log or update the detailed logging below to include armv7l.

Suggested change

console.log('Building Linux packages for architectures: x64, arm64 (Raspberry Pi 5), armv7l')

console.log('Building Linux packages (see individual build logs for architectures)')
