How to Use Stack Overflow for Troubleshooting ?

1. Identify Your Error:  

Begin by noting down the exact error message you encounter. For example:  

   - `cannot find make`  

   - `teammate cannot find Python 3`  

   - `no cmakecxx compiler can be found`  

2. Google Search the Error:  

- Open Google, and type your error along with "Stack Overflow."  

- Example: _“cannot find make site:stackoverflow.com”_

Examples of Common Errors and Solutions :

Error 1: `cannot find make`  

After searching, you'll find several solutions like:  

- Checking if `make` is installed:   which make

- Adding the `make` path to your environment variables.  

Error 2: `teammate cannot find Python 3`  

Solutions often include ensuring the correct Python version is set as default or updating the symbolic link to point to the latest version.  

Error 3: `no cmakecxx compiler can be found`  

Possible fixes include installing the required compiler or adjusting your `PATH` variable.  

Why Stack Overflow Works :
