Resolving Undefined symbols for architecture x86_64 Errors in C+ + Compile Time

When working with C+ + , encountering compilation errors can be frustrating, especially for newcomers. One common problem that can arise is the error message:

This kind of error typically points to an issue with the linking process of your code rather than a syntax error within your code itself. In this guide, we’ll unpack this issue, why it occurs, and how to effectively resolve it.

The Error Explained

You may have seen the following error details when compiling your C+ + code:

This error indicates that the compiler is unable to locate the necessary symbols from the standard library that allow your code to run.

Identifying the Root Cause

The Compiler Mismatch

The primary reason for these errors is that you are using the C compiler (clang) instead of the C+ + compiler (clang+ + ). The C compiler cannot resolve C+ + specific functionalities and thus results in these undefined symbols in your code.

Context of the Issue

In your case, the command you used for compilation was:

This command attempts to compile your C+ + code with the C compiler, leading to the linking errors.

Solution: Use the Right Compiler

To resolve this error, you simply need to switch from clang to clang+ + . Here’s how you can do that:

Steps to Compile Correctly

Open your terminal.

Navigate to the directory where your C+ + source file resides.

Compile your C+ + file using clang+ + like this:

Additional Considerations

macOS Versions: Ensure that your version of macOS, which is Mojave 10.14.6, supports clang+ + , but generally, as long as you’ve installed the proper development tooling, you should be good to go.

Code Libraries: If you're using other libraries, make sure they are linked properly as those can cause similar errors if not included during the linking phase.

Conclusion

By using clang+ + instead of clang, you can resolve the Undefined symbols for architecture x86_64 error that arises due to a mismatch in compilers. This small adjustment can save you from hours of confusion. Happy coding!
