vsc 的Makefile怎么写urg覆盖率收集

在Visual Studio Code (VSC) 中，想要编写一个Makefile来收集测试覆盖率，通常会涉及到使用特定的工具，比如CMake、gcov或lcov配合CTest等。以下是创建一个基本Makefile示例，用于C++项目并利用gcov收集覆盖率：

# Makefile for C++ project with coverage reporting using gcov

CC = gcc
CXX = g++
ifeq ($(shell uname), Darwin)
    # For macOS, use llvm-cov instead of gcov
    COVERAGE_TOOLS = llvm-cov gcov-8
else
    COVERAGE_TOOLS = gcov
endif

# Build target
all: my_program

# Compile without coverage report
clean:
	rm -f *.o my_program core*

# Compile with coverage report
coverage: COVERAGE_FLAGS = -O0 -ftest-coverage
coverage: my_program
	$(COVERAGE_TOOLS)/gcov-llvm report -show-covered-blocks $(my_program)

# Run tests and generate coverage report
test_coverage:
	cmake --build . --target test COVERAGE_FLAGS=-DCMAKE_CXX_FLAGS=$(COVERAGE_FLAGS)
	@echo "Coverage report generated. Open `lcov.info` file to view it."

# Generate lcov.info from the build directory
gen_lcov:
	cmake --build . --target gen_coverage_report
	genhtml lcov.info -o htmlcov

# Clean up after coverage generation
clean_coverage:
	rm -rf htmlcov lcov.info .coverage

# Default target is to build the program
my_program: %.o %.cpp
	$(CXX) $^ -o $@

%.o: %.cpp
	$(CC) $(COVERAGE_FLAGS) -c $<

.PHONY: clean coverage test_coverage gen_lcov clean_coverage all

#
