Quick Start

Common Requirement Python

• Python-2.7.17+, Python-3.7+

Prerequisites

1. Enter axmol root directory
2. Run python setup.py, restart the console after it has finished for environment variables to take effect

Creating A New Project

Using a console window, the command to generate a new project is as follows:

axmol new -p YOUR.UNIQUE.ID -d PROJECT_PATH -l [cpp|lua]

Examples:

• Cpp: axmol new -p org.axmol.hellocpp -d D:\dev\projects\ -l cpp --portrait HelloCpp
• Lua: axmol new -p org.axmol.hellolua -d D:\dev\projects\ -l lua --portrait HelloLua

Windows (64/32 bit Visual Studio 2019/2022)

1. Install CMake 3.22.1+

2. Install Visual Studio 2019/2022 (it's recommended that you only use these versions)

3. Create a new project as shown here

4. In a console window, navigate into the root directory of the project you created in the previous step

5. Generate the relevant Visual Studio project using the cmake command:

   cmake -S SOURCE_DIR -B BUILD_DIR -G VISUAL_STUDIO_VERSION_STRING -A [Win32|x64]

   For example, say SOURCE_DIR is the current path ".", and BUILD_DIR (out-of-source build directory) is named "build":

   a) C++ 20:

   • for 32 bit Visual Studio 2019: cmake -S . -B build -G "Visual Studio 16 2019" -A Win32
   • for 64 bit Visual Studio 2019: cmake -S . -B build -G "Visual Studio 16 2019" -A x64
   • for 32 bit Visual Studio 2022: cmake -S . -B build -G "Visual Studio 17 2022" -A Win32
   • for 64 bit Visual Studio 2022: cmake -S . -B build -G "Visual Studio 17 2022" -A x64

   b) C++17 - add -DCXX_STD=17 for C++17 on your command line like:
   cmake -S . -B build -DCXX_STD=17 -G "Visual Studio 17 2022" -A x64

6. Use Visual Studio to open the newly created solution file. For example, ./build/ProjectName.sln

Creating the Visual Studio solution for all axmol test projects:

1. Open a console window (Command Prompt, Window Terminal or Powershell)

2. Navigate into the folder where axmol is installed. For example:

   cd axmol

3. Run one of the following commands to create the Visual Studio solution for all axmol test projects in a folder named build:

   a) C++ 20:

   • for 32 bit Visual Studio 2019: cmake -S . -B build -G "Visual Studio 16 2019" -A Win32
   • for 64 bit Visual Studio 2019: cmake -S . -B build -G "Visual Studio 16 2019" -A x64
   • for 32 bit Visual Studio 2022: cmake -S . -B build -G "Visual Studio 17 2022" -A Win32
   • for 64 bit Visual Studio 2022: cmake -S . -B build -G "Visual Studio 17 2022" -A x64

   b) C++17

   • add -DCXX_STD=17 for C++17 on your command line like:
     cmake -S . -B build -DCXX_STD=17 -G "Visual Studio 17 2022" -A x64

4. You may either open the solution (".\build\axmol.sln") in Visual Studio and build any of the test projects via the IDE, or alternatively, build a project on the command line as follows (e.g. cpp-tests):
   msbuild .\build\axmol.sln -target:cpp_tests -maxCpuCount

Improve 'Visual Studio' workflow, support linking with engine prebuilt libs

See windows workflow guide

Android

With Android Studio

1. Install Android Studio 2021.1.1+
2. When starting Android Studio for the first time, it will guide you to install the SDK and other tools, so ensure that you do install them.
3. Start Android and choose [Open an existing Android Studio Project] and select your project. For example, the existing cpp-test project located in axmol\tests\cpp-tests\proj.android
4. Start Android Studio and Open [Tools][SDKManager], then switch to SDK Tools, check the Show Package Details, choose the following tools and click the button Apply to install them:
   • Android SDK Platform 33
   • Android Gradle Plugin (AGP) 7.2.2
   • Android SDK Build-Tools 30.0.3 match with AGP, refer to: https://developer.android.com/studio/releases/gradle-plugin
   • Gradle 7.4.2
   • NDK r23c+
   • CMake 3.22.1+
5. Wait for Gradle sync finish.
6. Note: If you use non-sdk provided CMake edition, you will need to download ninja from https://github.com/ninja-build/ninja/releases, and copy ninja.exe to cmake's bin directory

Without Android Studio

1. Download command-tools from https://developer.android.com/studio#command-tools
2. Install Android devtools (for example in windows)

# unzip command-tools at D:\dev\adt\
# Install android devtools
cd D:\dev\adt\
mkdir sdk
.\cmdline-tools\bin\sdkmanager.bat --verbose --sdk_root=D:\dev\adt\sdk "platform-tools" "cmdline-tools;latest" "platforms;android-33" "build-tools;30.0.3" "cmake;3.22.1" "ndk;23.2.8568313"
set ANDROID_HOME=D:\dev\adt\sdk

# Goto xxx\proj.android
.\gradlew.bat assembleRelease -PPROP_BUILD_TYPE=cmake -PPROP_APP_ABI=arm64-v8a --parallel --info

iOS, tvOS and macOS

1. Ensure xcode12+ & cmake3.21+ are installed, install cmake command line support: sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install

2. Create a new project as shown here

3. In a console window, navigate into the root directory of the project you created in the previous step

4. Execute the following command
   sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

5. Generate the relevant xcode project using one of the following commands:

   • for ios arm64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=OS64
   • for ios armv7,arm64 combined:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=OS
   • for ios simulator x86_64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR64
   • for tvos arm64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=TVOS
   • for tvos simulator x86_64:
     cmake -S . -B build -GXcode -DCMAKE_TOOLCHAIN_FILE=$AX_ROOT/cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR_TVOS
   • for macos x86_64(Intel) cmake -S . -B build -GXcode -DCMAKE_OSX_ARCHITECTURES=x86_64
   • for macos arm64(M1) cmake -S . -B build -GXcode -DCMAKE_OSX_ARCHITECTURES=arm64

6. After cmake finishes generating, you can open the xcode project at build folder and run cpp-tests or other test targets.

7. Notes

   • The code signing is required to run the ios/tvos app on your device, just change the bundle identifier until the auto manage signing is solved
   • axmol only provides armv7, arm64, x86_64 prebuilt libraries for ios/tvos

Notes

• ThreadLocalStorage (TLS)
  • ios x86 simulator ios>=10 and axmol no longer provide x86 libraries
  • ios x64 or devices (armv7, arm64) ios sdk>=9.0
  • the 'OpenAL Soft' maintained by kcat uses TLS
