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.
