C++报错集合：error: 'CppUnit::TestFixture' is an inaccessible base of 'LMQueryConnectionTest'

编译后报错：

 LMQueryConnectionTest.cc:194:   instantiated from here
/home/dts/users2/yujia.tao/DTS/trunk/vendor/cppunit/linux_gcc4/include/cppunit/extensions/TestFixtureFactory.h:41: error: 'CppUnit::TestFixture' is an inaccessible base of 'LMQueryConnectionTest'

 

出错处为：

在LMQueryConnectionTest.h头文件里，

class LMQueryConnectionTest:public LMQueryConnection
                          , public LMQueryConnectionParam
                          , public CppUnit::TestFixture {

                                                 XXXXXX；

                            };

CppUnit::TestFixture之前的public忘记写了。细节！
