You may require additional files to run the clang. If your files are missing, you may face the error “no input files.” Hence, install the XCode installer; it will install all the necessary files to run Clang.

To install the Xcode installer, use the following command:

xcode-select — install

2. Check The File Directory

To run a script, your script and terminal should be in the same file directory. If that’s not the case, you may encounter an error. To fix the Err Blocked By Response, select a folder, navigate it, right-click on it, and open the terminal.

The script and the terminal are in the same directory, so it should work fine. If you still face an error message, then there may be some other cause behind the error.

3. Find The Xcode Library

When you install Xcode, your computer may fail to find the location. Such reasons may inhibit the running of the clang. You may face an error such as SQL Developer Not Responding.

To fix the error caused by this reason, you need to point to the Xcode installation place so that your computer may find it easily. To do this, use the following command to say to Xcode:

 sudo xcode-select –switch /Applications/

4. Specify The GCC Version

To fix the Err_Connection_Reset, you will have to specify the GCC version installed on your computer. You can find the GCC version using the following command:

gcc -v

Once found, you can specify it easily.

5. Locate the Project Explorer

You can also fix the error from the above-given options from the project explorer Visual Studio Code Window is Not Responding. Open the project explorer and look for the vote in the file inspector. 

Find the option that says “Location” among the many options available. Please choose this option, make it your only path, and try to gain. I hope now you will get rid of this problem.
