checkmake is a linter for Makefiles that helps enforce best practices and identify common issues in Makefile syntax and structure. It helps prevent common Makefile pitfalls and makes build processes more reliable and maintainable.

Key Features:

Makefile rule validation ensuring proper target and dependency syntax
Proper indentation checking verifying correct tab usage vs. spaces
Variable usage verification detecting undefined or misused variables
Target naming convention enforcement following Makefile best practices
Missing dependency detection preventing incomplete build processes
Unreachable target identification optimizing Makefile structure
Tab character validation ensuring Make compatibility requirements
Rule pattern analysis catching common syntax errors
Configuration file support via .checkmake.ini for project-specific rules
Detailed error reporting with line numbers and suggestions
Build optimization suggestions improving compilation efficiency
