Verifies virtual_keyboard binary exists 2. Verifies keyboard_writer binary exists 3. Verifies both binaries are executable - Updated .PHONY to include 'check' target - Ensures CI can validate build artifacts properly Code Quality Improvements (virtual_keyboard.c): ----------------------------------------------- - Fixed unused parameter warning in cleanup() function - Added (void)signo cast to suppress -Wunused-parameter warning - Maintains clean compilation with -Wall -Wextra flags - No functional changes, purely cosmetic fix CI Pipeline Flow: ----------------- 1. Checkout code 2. Install build dependencies 3. Compile project (make) 4. Run validation checks (make check) 5. Clean build artifacts (make clean) All steps verified locally and passing successfully. --- .github/workflows/c-cpp.yml | 12 ++++++------ Makefile | 13 ++++++++++++- virtual_keyboard.c | 1 + 3 files
