How to Fix "error: linker cc not found" When Compiling a Rust Application

This error is actually quite simple; find the solution here.

error: linker cc not found

If you encounter the error message “Error: Linker cc not found” while compiling Rust applications, it means that the required linking tools are missing from your system. This problem commonly occurs when the system lacks the necessary build tools or C/C++ compilers. Here’s how to fix the issue on different platforms.

Fixing on Linux (Including Ubuntu/WSL)

To resolve this issue on Linux-based systems, ensure that build essentials and C/C++ compilers are installed.

Open a terminal and run the following command to install build essentials:

sudo apt-get install build-essential

Fixing on macOS

For macOS, you may need to install Xcode Command Line Tools to get the necessary compiler and linker.

Open Terminal and run the following command:

xcode-select --install

Fixing on Windows

On Windows, you need Visual Studio Build Tools to acquire the necessary compiler and linker.

Check GCC/Clang Installation

After installation, open Terminal and run:

gcc --version

on Windows, please open Command Prompt or PowerShell and run:

clang --version

Recompile the Rust Application

If GCC is installed, recompile the Rust application to confirm if the issue is resolved on the Terminal:

cargo run


Since Rust uses linking tools, your computer must have C/C++ build tools installed.
