• OpenSSL
• OpenVPN
• ShadowSocks
• Qt
• LibSsh - forked from Qt Creator
• and more...

How to build an iOS app from source code on MacOS

1. First, make sure you have XCode installed, at least version 14 or higher.

2. We use QT to generate the XCode project. We need QT version 6.6.1. Install QT for MacOS here or QT Online Installer. Required modules:

   • MacOS
   • iOS
   • Qt 5 Compatibility Module
   • Qt Shader Tools
   • Additional Libraries:
     • Qt Image Formats
     • Qt Multimedia
     • Qt Remote Objects

3. Install CMake if required. We recommend CMake version 3.25. You can install CMake here

4. You also need to install go >= v1.16. If you don't have it installed already, download go from the official website or use Homebrew. The latest version is recommended. Install gomobile

export PATH=$PATH:~/go/bin
go install golang.org/x/mobile/cmd/gomobile@latest
gomobile init

5. Build the project

export QT_BIN_DIR="<PATH-TO-QT-FOLDER>/Qt/<QT-VERSION>/ios/bin"
export QT_MACOS_ROOT_DIR="<PATH-TO-QT-FOLDER>/Qt/<QT-VERSION>/macos"
export QT_IOS_BIN=$QT_BIN_DIR
export PATH=$PATH:~/go/bin
mkdir build-ios
$QT_IOS_BIN/qt-cmake . -B build-ios -GXcode -DQT_HOST_PATH=$QT_MACOS_ROOT_DIR

Replace PATH-TO-QT-FOLDER and QT-VERSION to your environment

If you get gomobile: command not found make sure to set PATH to the location of the bin folder where gomobile was installed. Usually, it's in GOPATH.

export PATH=$(PATH):/path/to/GOPATH/bin

6. Open the XCode project. You can then run /test/archive/ship the app.

If the build fails with the following error

make: *** 
[$(PROJECTDIR)/client/build/AmneziaVPN.build/Debug-iphoneos/wireguard-go-bridge/goroot/.prepared] 
Error 1

Add a user-defined variable to both AmneziaVPN and WireGuardNetworkExtension targets' build settings with key PATH and value ${PATH}/path/to/bin/folder/with/go/executable, e.g. ${PATH}:/usr/local/go/bin.

if the above error persists on your M1 Mac, then most probably you need to install arch based CMake

arch -arm64 brew install cmake

Build might fail with the "source files not found" error the first time you try it, because the modern XCode build system compiles dependencies in parallel, and some dependencies end up being built after the ones that require them. In this case, simply restart the build.

How to build the Android app

Tested on Mac OS

The Android app has the following requirements:

• JDK 11
• Android platform SDK 33
• CMake 3.25.0

After you have installed QT, QT Creator, and Android Studio, you need to configure QT Creator correctly. Click in the top menu bar on QT Creator -> Preferences -> Devices and select the tab Android. * set path to JDK 11 * set path to Android SDK ($ANDROID_HOME)

In case you get errors regarding missing SDK or 'SDK manager not running', you cannot fix them by correcting the paths. If you have some spare GBs on your disk, you can let QT Creator install all requirements by choosing an empty folder for Android SDK location and clicking on Set Up SDK. Be aware: This will install a second Android SDK and NDK on your machine!  Double-check that the right CMake version is configured:  Click on QT Creator -> Preferences and click on the side menu on Kits. Under the center content view's Kits tab, you'll find an entry for CMake Tool. If the default selected CMake version is lower than 3.25.0, install on your system CMake >= 3.25.0 and choose System CMake at <path> from the drop-down list. If this entry is missing, you either have not installed CMake yet or QT Creator hasn't found the path to it. In that case, click in the preferences window on the side menu item CMake, then on the tab Tools in the center content view, and finally on the button Add to set the path to your installed CMake.  Please make sure that you have selected Android Platform SDK 33 for your project: click in the main view's side menu on Projects, and on the left, you'll see a section Build & Run showing different Android build targets. You can select any of them, Amnezia VPN's project setup is designed in a way that all Android targets will be built. Click on the targets submenu item Build and scroll in the center content view to Build Steps. Click on Details at the end of the headline Build Android APK (the Details button might be hidden in case the QT Creator Window is not running in full screen!). Here we are: Choose android-33 as Android Build Platform SDK.

That's it! You should be ready to compile the project from QT Creator!

Development flow

After you've hit the build button, QT-Creator copies the whole project to a folder in the repository parent directory. The folder should look something like build-amnezia-client-Android_Qt_<version>_Clang_<architecture>-<BuildType>. If you want to develop Amnezia VPNs Android components written in Kotlin, such as components using system APIs, you need to import the generated project in Android Studio with build-amnezia-client-Android_Qt_<version>_Clang_<architecture>-<BuildType>/client/android-build as the projects root directory. While you should be able to compile the generated project from Android Studio, you cannot work directly in the repository's Android project. So whenever you are confident with your work in the generated project, you'll need to copy and paste the affected files to the corresponding path in the repository's Android project so that you can add and commit your changes!

You may face compiling issues in QT Creator after you've worked in Android Studio on the generated project. Just do a ./gradlew clean in the generated project's root directory (<path>/client/android-build/.) and you should be good to go.
