As a developer, you may have encountered the "Symbol(s) Not Found for Architecture x86_64" error when building your project. This error occurs when you are trying to link a library or framework that was built for a different architecture than the one you are currently using. In this guide, we will provide you with a step-by-step solution on how to troubleshoot and fix this error.
Understanding the Error
Before we dive into the solution, let's understand what this error means. The x86_64 architecture is a 64-bit architecture used by many modern CPUs, including Intel and AMD processors. When you compile your code, it generates object files that are specific to the architecture you are using. If you try to link a library or framework that was built for a different architecture, you will get the "Symbol(s) Not Found for Architecture x86_64" error.
Solution
To fix this error, you need to make sure that all the libraries and frameworks you are linking were built for the same architecture as your project. Here are the steps to follow:
Check the architecture of your project by running the following command in the terminal:
file <your_project_binary>
Replace <your_project_binary> with the name of your project's binary file.
Check the architecture of the library or framework that is causing the error by running the following command:
file <library_or_framework_binary>
Replace <library_or_framework_binary> with the name of the library or framework's binary file.
If the architectures do not match, you need to rebuild the library or framework for the correct architecture. You can do this by following the instructions provided by the library or framework's documentation.
- Once you have rebuilt the library or framework, make sure to link it with your project.
