Here is the djinni tutorial step by step. http://mobilecpptutorials.com/cross-platform-cplusplus-dev-setup-on-os-x-yosemite/ 1. The deps folder is generated by following commands: ———————————————————————————————————————————————————————————————————————————— git init git submodule add https://github.com/dropbox/djinni.git deps/djinni git submodule add https://chromium.googlesource.com/external/gyp.git deps/gyp We actually need an older version of GYP to build Android files. To do this, we need to cd into deps/gyp and specify a commit: cd deps/gyp git checkout -q 0bb67471bca068996e15b56738fa4824dfa19de0 ———————————————————————————————————————————————————————————————————————————— 2. Setup the Djinni file ———————————————————————————————————————————————————————————————————————————— (ProjectRoot)/helloworld.djinni hello_world = interface +c { static create(): hello_world; get_hello_world(): string; } ———————————————————————————————————————————————————————————————————————————— 3. Create the Djinni Shell Script ———————————————————————————————————————————————————————————————————————————— #! /usr/bin/env bash base_dir=$(cd "`dirname "0"`" && pwd) cpp_out="$base_dir/generated-src/cpp" jni_out="$base_dir/generated-src/jni" objc_out="$base_dir/generated-src/objc" java_out="$base_dir/generated-src/java/com/mycompany/helloworld" java_package="com.mycompany.helloworld" namespace="helloworld" objc_prefix="HW" djinni_file="helloworld.djinni" deps/djinni/src/run \ --java-out $java_out \ --java-package $java_package \ --ident-java-field mFooBar \ \ --cpp-out $cpp_out \ --cpp-namespace $namespace \ \ --jni-out $jni_out \ --ident-jni-class NativeFooBar \ --ident-jni-file NativeFooBar \ \ --objc-out $objc_out \ --objc-type-prefix $objc_prefix \ \ --objcpp-out $objc_out \ \ --idl $djinni_file ———————————————————————————————————————————————————————————————————————————— 4. Run the above script ———————————————————————————————————————————————————————————————————————————— sh ./run_djinni.sh Building Djinni...
