If you're a C++ developer and you've come across the "cc1plus: error: unrecognized command line option "-std=c++11"" error, don't worry. This error message usually means that you're trying to use a C++11 feature, but your compiler doesn't support it. In this guide, we'll provide you with tips and solutions on how to fix this error.
Check Your Compiler Version
The first thing you should do is check your compiler version to see if it supports C++11. If you're using GCC, you can check the version by running the following command:
g++ --version
If your version is lower than 4.8, it's likely that your compiler doesn't support C++11. You can either upgrade your compiler or try using a different one.
Use the Right Flag
If you've verified that your compiler supports C++11, the next step is to make sure you're using the right flag. In most cases, you'll need to use the "-std=c++11" flag to enable C++11 features. Here's an example command:
g++ -std=c++11 main.cpp -o main
Double Check Your Code
If you're still getting the error message after using the right flag, it's possible that there's an issue with your code. Double check your code to make sure you're not using any C++11 features that aren't supported by your compiler.
Use a Different Compiler
If none of the above solutions work, you can try using a different compiler that supports C++11. Some popular options include Clang and Visual C++.
