c - "make: *** No rule to make target" 使用 Unity 单元测试

问题描述

我最终安装了 ceedling，它使用 ruby​​ 代码自动生成测试运行。学习imo更好的工具集。我将保留这个问题，以防其他人有同样的问题并且其他人有答案。

嗨 StackOverflow 家族，

我目前正在阅读“嵌入式 C 的测试驱动开发”，并试图让 Unity（单元测试器）工作。我可以使用 gcc编译一些示例代码。

当我尝试按照制作教程并在命令行中运行“make”时：

make: *** No rule to make target 'build/results/TestEx.txt', needed by 'test'.  Stop.

我尝试遵循throwtheswitch 中的树轮廓，我的个人树如下（为清楚起见，删除了 Unity 的文件）：

.
├── build
│   ├── depends
│   ├── objs
│   └── results
├── makefile
├── src
│   ├── ex.c
│   └── ex.h
├── test
│   └── TestEx.c
├── testex
└── Unity
.

.

.

我的makefile看起来像这样（记住，它是复制的）：

ifeq ($(OS),Windows_NT)
  ifeq ($(shell uname -s),) # not in a bash-like shell
    CLEANUP = del /F /Q
    MKDIR = mkdir
  else # in a bash-like shell, like msys
    CLEANUP = rm -f
    MKDIR = mkdir -p
  endif
    TARGET_EXTENSION=.exe
else
    CLEANUP = rm -f
    MKDIR = mkdir -p
    TARGET_EXTENSION=out
endif

.PHONY: clean
.PHONY: test

PATHU = Unity/src/
PATHS = src/
PATHT = test/
PATHB = build/
PATHD = build/depends/
PATHO = build/objs/
PATHR = build/results/

BUILD_PATHS = $(PATHB) $(PATHD) $(PATHO) $(PATHR)

SRCT = $(wildcard $(PATHT)*.c)

COMPILE=gcc -c
LINK=gcc
DEPEND=gcc -MM -MG -MF
CFLAGS=-I. -I$(PATHU) -I$(PATHS) -DTEST

RESULTS = $(patsubst $(PATHT)Test%.c,$(PATHR)Test%.txt,$(SRCT) )

PASSED = `grep -s PASS $(PATHR)*.txt`
FAIL = `grep -s FAIL $(PATHR)*.txt`
IGNORE = `grep -s IGNORE $(PATHR)*.txt`

test: $(BUILD_PATHS) $(RESULTS)
    @echo "-----------------------\nIGNORES:\n-----------------------"
    @echo `grep -s IGNORE $(PATHR)*.txt`
    @echo "-----------------------\nFAILURES:\n-----------------------"
    @echo `grep -s FAIL $(PATHR)*.txt`
    @echo "-----------------------\nPASSED:\n-----------------------"
    @echo "$(PASSED)"
    @echo "\nDONE"

$(PATHR)%.txt: $(PATHB)%.$(TARGET_EXTENSION)
    -./$< > $@ 2>&1

$(PATHB)Test%.$(TARGET_EXTENSION): $(PATHO)Test%.o $(PATHO)%.o $(PATHU)unity.o #$(PATHD)Test%.d
    $(LINK) -o $@ $^

    $(COMPILE) $(CFLAGS) $< -o $@

    $(COMPILE) $(CFLAGS) $< -o $@

    $(MKDIR) $(PATHD)

    $(MKDIR) $(PATHO)

clean:
    $(CLEANUP) $(PATHO)*.o
    $(CLEANUP) $(PATHB)*.$(TARGET_EXTENSION)
    $(CLEANUP) $(PATHR)*.txt

.PRECIOUS: $(PATHB)Test%.$(TARGET_EXTENSION)
.PRECIOUS: $(PATHD)%.d
.PRECIOUS: $(PATHO)%.o
.PRECIOUS: $(PATHR)%.txt

运行make -d test（删除文本以适应正文，但浓缩为重要部分）：

解决方案

生病重新打开线程，因为我无法找到相同问题的解决方案。

您是否使用为 GNUWin32 构建的 GNU make？

我发现 GNUWin32 make 使用 Unix 样式的文件名作为目标和依赖项，但是由于我已将 makefile 的 PATHS 编辑为 Windows 样式的文件名以使用 windowsmkdir命令，因此 makefile 无法找到配方。

如果您使用为 GNUWin32 构建的 GNU Makefile 运行它，则应该编辑您的 makefile

Makefile 规则路径应该是这样的：

test/build/objs/%.o: test/%.c

mkdir 命令应该是这样的：

mkdir test\build\objs

这对我有用。希望它有帮助！
