If you're encountering the "Missing Separator" error in Makefile:2, it means that there's a syntax error in your Makefile. This error occurs when there's a missing tab character at the beginning of a recipe line. In this guide, we'll take you through the steps to troubleshoot and fix this error.
Steps to Troubleshoot "Missing Separator" Error
First, locate the Makefile that's causing the error. You can do this by running the make command with the -n option, which will print the commands that would be executed. For example:
make -n -f Makefile
Look for the line that starts with a recipe (i.e., a command that should be executed). The error message will indicate the line number where the error occurred. For example:
Makefile:2: *** missing separator. Stop.
This means that there's a missing separator at line 2.
Check if there's a tab character at the beginning of the recipe line. Make sure that it's a tab character and not spaces. Spaces will not work and will result in the "Missing Separator" error.
If there's no recipe line at line 2, check the line above it. Sometimes, the error occurs in the line before the one indicated by the error message.
Once you've added the missing tab character, save the Makefile and try running make again.
