Netbean 集成 CppUnit 问题
当使用Netbean搭配C++插件开发时，如果使用CppUnit进行测试，每添加一个测试有一定概率会破坏Makefile文件，导致找不到CppUnit：
?
/home/programmer/workspace/InterviewTest/CppInterview/tests/SortClass.cpp:38: undefined reference to `CppUnit::SourceLine::SourceLine(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)'/home/programmer/workspace/InterviewTest/CppInterview/tests/SortClass.cpp:38: undefined reference to `CppUnit::SourceLine::~SourceLine()'/home/programmer/workspace/InterviewTest/CppInterview/tests/SortClass.cpp:38: undefined reference to `CppUnit::SourceLine::~SourceLine()'build/Debug/GNU-Linux-x86/tests/tests/SortClass.o: In function `SortClass::getTestNamer__()':/home/programmer/workspace/InterviewTest/CppInterview/tests/SortClass.h:14: undefined reference to `CppUnit::TestNamer::TestNamer(std::type_info const&)'/home/programmer/workspace/InterviewTest/CppInterview/tests/SortClass.h:14: undefined reference to `CppUnit::TestNamer::~TestNamer()'build/Debug/GNU-Linux-x86/tests/tests/SortClass.o: In function `~TestSuiteBuilderContext':/usr/include/cppunit/extensions/TestSuiteBuilderContext.h:101: undefined reference to `CppUnit::TestSuiteBuilderContextBase::~TestSuiteBuilderContextBase()'/usr/include/cppunit/extensions/TestSuiteBuilderContext.h:101: undefined reference to `CppUnit::TestSuiteBuilderContextBase::~TestSuiteBuilderContextBase()'build/Debug/GNU-Linux-x86/tests/tests/SortClass.o: In function `SortClass::addTestsToSuite(CppUnit::TestSuiteBuilderContextBase&)':/home/programmer/workspace/InterviewTest/CppInterview/tests/SortClass.h:16: undefined reference to `CppUnit::TestSuiteBuilderContextBase::getTestNameFor(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) const'/home/programmer/workspace/InterviewTest/CppInterview/tests/SortClass.h:16: undefined reference to `CppUnit::TestSuiteBuilderContextBase::addTest(CppUnit::Test*)'build/Debug/GNU-Linux-x86/tests/tests/SortClass.o: In function `SortClass::suite()':

这是Netbean的issue，它会自动把一些运行测试时的-lcppunit参数删除了。
?
解决方法：
?
打开nbproject/Makefile-Debug.mk，在.build-tests-conf: .build-conf ${TESTFILES}以下的每个${LDLIBSOPTIONS}后面加上 -lcppunit 参数
?
?
------------------------------------------------
.build-tests-conf: .build-conf ${TESTFILES}
${TESTDIR}/TestFiles/f1: ${TESTDIR}/tests/SortClass.o ${TESTDIR}/tests/testrunnerone.o ${OBJECTFILES:%.o=%_nomain.o}
${MKDIR} -p ${TESTDIR}/TestFiles
${LINK.cc} -o ${TESTDIR}/TestFiles/f1 $^ ${LDLIBSOPTIONS} -lcppunit

每添加一个测试有一定概率会自动删除-lcppunit参数，所以需要手动加上去，等后续的netbean C++插件解决吧。
