How to Install GCC in Termux for C++ Programming

Termux is a versatile terminal emulator for Android that transforms your mobile device into a portable Linux environment. By using Termux, you can seamlessly access a wide range of Linux utilities, including the ability to compile and run C++ programs directly on your phone or tablet. This is made possible through the installation of GCC (GNU Compiler Collection), a powerful tool used for compiling various programming languages, including C++. Whether you’re a student learning to code, a developer seeking to experiment on the go, or someone needing a quick and lightweight C++ development setup, Termux offers an efficient and portable solution.

With Termux and GCC, you can set up a fully functional C++ development environment on your Android device. This setup is ideal for developers who want to write, compile, and test code without needing access to a full desktop environment. It also benefits educators and learners who can use their mobile devices to practice coding anywhere, anytime. The guide will walk you through the installation and configuration process, enabling you to dive into C++ programming swiftly and effectively. By using Termux, you avoid the need for bulky laptops and can leverage the convenience of mobile technology to code, compile, and test applications on the go.

Verify GCC Installation

After installation, verify that GCC is installed correctly by checking the version:

$ clang --version

You should see output indicating the version of the compiler, confirming that you have successfully installed GCC in Termux for C++ programming.

Write and Compile a C++ Program

Once you install GCC in Termux for C++ development, it’s time to test the setup by writing and compiling a simple C++ program. Use a text editor like nano to create your first C++ file:

$ nano hello.cpp

Add the following C++ code to hello.cpp:

#include <iostream>

int main() {
    std::cout << "Hello, Termux!" << std::endl;
    return 0;
}

Save the file and exit the editor. Compile the program using GCC in Termux:

$ clang++ -o hello hello.cpp

Run the compiled program:

$ ./hello

You should see the output: Hello, Termux!, confirming that your C++ development environment is working.

Additional Tips

• Libraries and Dependencies: If your C++ program requires additional libraries, you can install them using Termux’s package manager (pkg).
• IDE Support: Consider using a text editor like vim or emacs in Termux for more advanced coding features.
• GDB: Install gdb for debugging your C++ programs:

$ pkg install gdb

Conclusion

Installing GCC for C++ programming in Termux is straightforward and allows you to compile and run C++ programs directly on your Android device. With the clang package, you can leverage the power of GCC in Termux to develop and test your C++ code on the go.
