SLib

SLib is a universal cross-platform library, specially designed for the various UI components, OpenGL rendering and networking solutions.

SLib enables software developers to build multi-platform(Android/iOS/MacOS/Tizen/Win32) applications and games under the most effective workflows and the coding conventions of C++, while providing easy-to-use toolkits to develop HTTP/Socket servers on the Linux/MacOS/Win32 platforms.

Getting Started

Prerequisites

• Xcode 9.4 or higher for compiling macOS/iOS packages
• Android Studio 3.2 or higher for compiling Android packages
• Visual Studio 2017 or higher for compiling Win32 packages
• Tizen Studio 1.1.1 or higher for compiling Tizen packages
• CMake (>=3.0), GCC/C++ (>=4.8.1) for compiling Linux packages. Optional: KDevelop(>=4.7)

Clone the repository from Github.

 git clone https://github.com/SLIBIO/SLib.git

Build the static libraries

You can see the following projects in build directory.

Project	Description
Android	Android Studio project for Android
iOS	Xcode project for iOS
macOS	Xcode project for macOS
Win32	Visual Studio solution for Win32
Tizen	Tizen Studio project for Tizen
Linux	CMake/KDevelop project for Linux

After compiling the projects, you can find the static libraries in the lib directory.

Setup Environment

It's time to setup the environment variables. It is a bit different depending on the platforms.

On macOS and Linux, you'll need to run the setup-path script on Terminal or Finder.

 ./setup-path

On Windows, you'll need to run the setup-path.bat batch file on Command Prompt or File Explorer.

 setup-path.bat

setup-path will register the current source directory as SLIB-PATH environment variable depending on the Operating Systems and IDEs(XCode and KDevelop).

After setting up the environment variables, please close all the running IDEs(Xcode, Android Studio, Tizen Studio,...) and terminal (or konsole) windows, and then reopen them. (on macOS, press Command+Q to completely close the IDEs).

Creating new projects based on SLib

After setting up environment using setup-path(setup-path.bat), please reopen Terminal (Command Prompt) window.

And then please create an empty directory, and then create a C++ project using following commands.

Platform	Application Type	Command
Android iOS	Mobile App (With sapp)	new-slib-app-mobile YOUR_PROJECT_NAME YOUR_APPLICATION_ID
macOS Win32	Desktop App (With sapp)	new-slib-app-desktop YOUR_PROJECT_NAME
Android	Mobile App (Without sapp)	new-slib-app-android YOUR_PROJECT_NAME YOUR_APPLICATION_ID
iOS	Mobile App (Without sapp)	new-slib-app-ios YOUR_PROJECT_NAME
macOS	Desktop App (Without sapp)	new-slib-app-macos YOUR_PROJECT_NAME
macOS	Console App (Without sapp)	new-slib-console-macos YOUR_PROJECT_NAME
Win32	Desktop App (Without sapp)	new-slib-app-win32 YOUR_PROJECT_NAME
Win32	Console App (Without sapp)	new-slib-console-win32 YOUR_PROJECT_NAME
Linux	Desktop App (Without sapp)	new-slib-app-linux YOUR_PROJECT_NAME
Linux	Console App (Without sapp)	new-slib-console-linux YOUR_PROJECT_NAME

Note that you have to compile SLib before creating new SLib application projects.

Here is an example for creating a mobile app project.

mkdir ~/SLibMobileExample
cd ~/SLibMobileExample
new-slib-app-mobile Test org.example.testapp

To preview the user interface xml files

cd src/sapp/ui
sapp LaunchScreen
sapp MainPage

Here is an example for creating a desktop app project.

mkdir ~/SLibDesktopExample
cd ~/SLibDesktopExample
new-slib-app-desktop Test

Here is an example for creating an Android project.

mkdir ~/SLibAndroidExample
cd ~/SLibAndroidExample
new-slib-app-android Test org.example.testapp

Here is an example for creating a macOS Desktop project.

mkdir ~/SLibMacOSExample
cd ~/SLibMacOSExample
new-slib-app-macos Test

After creating projects, you can share same source code across the projects by adding same sources using IDE.

Integrating SLib with existing C++ projects

It is very easy to integrate SLib into your existing C++ project. You just need to setup include and lib directories into your existing C++ project.

Platform	IDE	Include Directory	Link Directory
Android	Android Studio (CMake)	${SLIB_PATH}/include	${SLIB_PATH}/lib/Android/${CMAKE_BUILD_TYPE}-${ANDROID_ABI}
iOS	Xcode	$(SLIB_PATH)/include	$(SLIB_PATH)/lib/iOS/$(CONFIGURATION)$(EFFECTIVE_PLATFORM_NAME)
Tizen	Tizen Studio	${SLIB_PATH}/include	${SLIB_PATH}/lib/Tizen/${ConfigName}-${SDK_ARCH}
macOS	Xcode	$(SLIB_PATH)/include	$(SLIB_PATH)/lib/macOS/$(CONFIGURATION)
Win32	Visual Studio	$(SLIB_PATH)/include	$(SLIB_PATH)/lib/Win32/$(Configuration)-$(Platform)
Linux	CMake, KDevelop	${SLIB_PATH}/include	${SLIB_PATH}/lib/Linux/${CMAKE_BUILD_TYPE}-${CMAKE_HOST_SYSTEM_PROCESSOR}

You can also integrate SLib into any types of C++ projects using similar include and lib directory rules.

Important: Your C++ project must be compiled with C++11 support.

After setup directories, link slib library via IDE or set -lslib option to the linker.

To make your project more portable, you can copy the include directory and the precompiled static libraries into your project and use the relative path instead of the environment variable.

Android Studio (using CMake)

Firstly, open and build the project in the build/Android directory in the SLib source. After completion of build, you can see the precompiled static libraries and slib.aar in the lib/Android directory.

Secondly, open your Android project created by yourself which will use SLib.

Important: Use gradle version 2.3.1 or higher.

Edit the build.gradle in your app module as following.

  ...
  android {
    ...
    defaultConfig {
      ...
      externalNativeBuild {
        ...
        cmake {
          cppFlags "-std=c++11"
          arguments "-DSLIB_PATH=${System.env.SLIB_PATH}"
        }
        ...
      }
      ndk {
        abiFilters 'armeabi-v7a', 'arm64-v8a', 'x86', 'x86_64'
      }

      ...
    }
  }
  ...
  repositories {
    ...
    flatDir{
       ...
       dirs "${System.env.SLIB_PATH}/lib/Android"
    }
  }
  dependencies {
    ...
    compile ':slib@aar'
  }
  

Edit CMakeLists.txt in your app module as following.

  ...
  include_directories (${SLIB_PATH}/include)
  link_directories (${SLIB_PATH}/lib/Android/${CMAKE_BUILD_TYPE}-${ANDROID_ABI})
  ...
  target_link_libraries (
    your-native-module-name
    ...
    slib
    log GLESv2 OpenSLES
    ...
  )
  ...

Edit the main cpp file (for example, native-lib.cpp), and insert the following code snippet.

#include <slib/core/platform_android.h>

JNIEXPORT jint JNI_OnLoad(JavaVM* jvm, void* reserved)
{
	slib::Android::initialize(jvm);
	return JNI_VERSION_1_4;
}

If you already defined JNI_OnLoad in somewhere, please insert slib::Android::initialize(jvm); in the existing definition, instead of inserting above code snippet.
