What’s the difference between gnu stl and stlport in Android NDK development?

In Android NDK development, you often have the choice between using two popular STL implementations: GNU STL and STLport. Understanding their differences is crucial for choosing the right library for your project.

GNU STL

Overview

GNU STL is the Standard Template Library implementation included with the GCC compiler. It’s widely used and generally considered the default choice for most C++ projects.

Features

• Good performance and stability.
• Well-documented and widely supported.
• Built-in support for exception handling.

STLport

Overview

STLport is an alternative STL implementation that aims for greater portability and compatibility across different platforms. It was originally designed to provide a consistent STL experience across platforms with limited C++ Standard Library support.

Features

• High portability, working on various platforms and compilers.
• Support for older C++ standards.
• Option to disable exception handling.

Comparison

Choosing the Right STL for your Android NDK project

• If you prioritize performance and are targeting primarily Android platforms, **GNU STL** is usually the better choice.
• If your project requires compatibility across different platforms, or if you need to work with older C++ standards, **STLport** might be a suitable option.
• Consider the trade-offs in terms of performance, platform compatibility, and the required C++ features before making your decision.

Example Code: Using STL containers

#include 

int main() {
  std::vector numbers = {1, 2, 3, 4, 5};

  for (int number : numbers) {
    std::cout << number << " ";
  }

  std::cout << std::endl;

  return 0;
}

Output:
1 2 3 4 5 

Conclusion

Both GNU STL and STLport have their strengths and weaknesses. Understanding their differences is crucial for making an informed decision based on your specific project requirements and preferences.
