You can create projects from custom templates:

# From GitHub repository
ccgo new my-project --template-url=https://github.com/user/my-template.git

# From local directory
ccgo new my-project --template-url=/path/to/local/template

The generated build.py script supports CI/CD workflows with environment variables:

• CI_IS_RELEASE - Build as release vs beta
• CI_BUILD_<PLATFORM> - Enable/disable platform builds

Example:

export CI_IS_RELEASE=1
export CI_BUILD_ANDROID=1
export CI_BUILD_IOS=1
python3 build.py

Build for multiple architectures simultaneously:

# Android: build for 32-bit ARM, 64-bit ARM, and x86_64
ccgo build android --arch armeabi-v7a,arm64-v8a,x86_64

# OHOS: build for all supported architectures
ccgo build ohos --arch armeabi-v7a,arm64-v8a,x86_64

1. "Command not found" after installation

   • Ensure pip3 install directory is in your PATH
   • Try python3 -m ccgo instead of ccgo

2. Android build fails

   • Verify ANDROID_HOME, ANDROID_NDK_HOME, and JAVA_HOME are set
   • Run ccgo check android --verbose to diagnose

3. OHOS build fails

   • Verify OHOS_SDK_HOME or HOS_SDK_HOME is set
   • Run ccgo check ohos --verbose to diagnose

4. iOS/macOS build fails

   • Ensure Xcode and command-line tools are installed
   • Run xcode-select --install if needed
