我是 cppuTest 的新手，实际上我正在尝试在 CppuTest 根目录中构建 ./examples 。源文件和测试文件的编译没有问题，但我停留在最后的链接阶段，我得到了这个错误：

C:\CppUTest\cpputest-3.7.1\examples>make

我在 Windows 7 上使用 MinGW。MinGW 还包含 pthread.a 库。我的makefil如下所示：

#---------
#
# CppUTest Examples Makefile
#
#----------

#Set this to @ to keep the makefile quiet
ifndef SILENCE
    SILENCE = @
endif

#--- Inputs ----#
COMPONENT_NAME = CppUTestExamples
CPPUTEST_HOME = ..

CPPUTEST_USE_EXTENSIONS = Y
CPP_PLATFORM = Gcc

CFLAGS = -Dmalloc=cpputest_malloc -Dfree=cpputest_free
CPPFLAGS =
GCOVFLAGS = -fprofile-arcs -ftest-coverage

LDFLAGS = -lpthread
#USER_LIBS = -lpthread

# This line is overriding the default new macros.  This is helpful
# when using std library includes like <list> and other containers
# so that memory leak detection does not conflict with stl.
CPPUTEST_MEMLEAK_DETECTOR_NEW_MACRO_FILE = -include     ApplicationLib/ExamplesNewOverrides.h
SRC_DIRS = \
    ApplicationLib

TEST_SRC_DIRS = \
    AllTests

INCLUDE_DIRS =\
  .\
  ApplicationLib\
  $(CPPUTEST_HOME)/include\

include $(CPPUTEST_HOME)/build/MakefileWorker.mk

如您所见，pthread 库被提供给带有 LDFLAGS 的链接器......

有人有类似经历吗？或者也许知道问题出在哪里？将感谢任何提示！

感谢@Keith Marshall 和@MadScientist，

所以代替 LDFLAGS = -lpthread

我用了：

LD_LIBRARIES += -lpthread

并将这一行直接放在前面：

include $(CPPUTEST_HOME)/build/MakefileWorker.mk

现在它起作用了。

从内置规则目录中可以看出：

链接单个目标文件

n通过 C 编译器n.o运行链接器（通常称为 ）自动生成。ld使用的精确配方是：

$(CC) $(LDFLAGS) n.o $(LOADLIBES) $(LDLIBS)

和隐式规则使用的变量：

LDFLAGS

当编译器应该调用链接器时提供给编译器的额外标志 ld，例如-L. -lfoo应将库 ( ) 添加到 LDLIBS 变量中。

所以在这种情况下-lpthread应该设置或添加到LDLIBS，而不是LDFLAGS。
