This commit ports the work of EchterAgo and cculianu from Electron-Cash, to implement a new toolchain to scan qr codes. Previously, on Linux and Win, we have been using zbar to access the camera and read qrcodes; and on macOS we used CalinsQRReader (an objective-C project by cculianu). The new toolchain added here can use QtMultimedia to access the camera, and then feed that image into zbar. When used this way, zbar needs fewer dependencies and is easier to compile, in particular it can be compiled for macOS. The new toolchain works on all three platforms, with some caveats (see code comments in related commits) -- so we also keep the end-to-end zbar toolchain; but at least we can drop CalinsQRReader. The related changes in Electron-Cash are spread over 50+ commits (several PRs and direct pushes to master), but see in particular: https://github.com/Electron-Cash/Electron-Cash/pull/1376 some other interesting links:b2b737001c163224cf1f3b31e0fcb1eda015908ehttps://github.com/Electron-Cash/Electron-Cash/pull/1545052aa06c23
Building macOS binaries
✗ This script does not produce reproducible output (yet!). Please help us remedy this. (see #7266)
This guide explains how to build Electrum binaries for macOS systems.
Building the binary
This needs to be done on a system running macOS or OS X.
Notes about compatibility with different macOS versions:
- In general the binary is not guaranteed to run on an older version of macOS than what the build machine has. This is due to bundling the compiled Python into the PyInstaller binary.
- The bundled version of Qt also imposes a minimum supported macOS version.
- If you want to build binaries that conform to the macOS "Gatekeeper", so as to minimise the warnings users get, the binaries need to be codesigned with a certificate issued by Apple, and starting with macOS 10.15 the binaries also need to be notarized by Apple's central server. The catch is that to be able to build binaries that Apple will notarise (due to the requirements on the binaries themselves, e.g. hardened runtime) the build machine needs at least macOS 10.14. See #6128.
We currently build the release binaries on macOS 10.14.6, and these seem to run on 10.13 or newer.
Before starting, make sure that the Xcode command line tools are installed (e.g. you have git).
Build Electrum
cd electrum
./contrib/osx/make_osx
This creates both a folder named Electrum.app and the .dmg file.
If you want the binaries codesigned for MacOS and notarised by Apple's central server,
provide these env vars to the make_osx script:
CODESIGN_CERT="Developer ID Application: Electrum Technologies GmbH (L6P37P7P56)" \
APPLE_ID_USER="me@email.com" \
APPLE_ID_PASSWORD="1234" \
./contrib/osx/make_osx
