netbeans多重定义;在构建C ++简单测试时首先在_nomain.o中定义错误

Question

我在项目目录的tests文件夹中创建了三个C ++简单测试。当我创建第一个C ++简单测试并构建它没有问题但是当我创建第二个或第三个时，生成下面列出的无数错误

build/DebugDynamic/GNU-Linux-x86/ClientSocket.o: In function `Socket::is_valid() const':
/home/gowtham/workspace/base/ClientSocket.cpp:8: multiple definition of `ClientSocket::ClientSocket(std::string, int, Socket::SOCKET_TYPE, std::string, std::string, std::string)'
build/DebugDynamic/GNU-Linux-x86/ClientSocket_nomain.o:/home/gowtham/workspace/base/ClientSocket.cpp:8: first defined here

链接器命令是

g++ -g -O0      -o build/DebugDynamic/GNU-Linux-x86/tests/TestFiles/f3 build/DebugDynamic/GNU-Linux-x86/tests/tests/sizeInfo.o build/DebugDynamic/GNU-Linux-x86/ClientSocket_nomain.o build/DebugDynamic/GNU-Linux-x86/FFJSON_nomain.o build/DebugDynamic/GNU-Linux-x86/JPEGImage_nomain.o build/DebugDynamic/GNU-Linux-x86/ServerSocket_nomain.o build/DebugDynamic/GNU-Linux-x86/Socket_nomain.o build/DebugDynamic/GNU-Linux-x86/logger_nomain.o build/DebugDynamic/GNU-Linux-x86/myconverters_nomain.o build/DebugDynamic/GNU-Linux-x86/mycurl_nomain.o build/DebugDynamic/GNU-Linux-x86/mystdlib_nomain.o build/DebugDynamic/GNU-Linux-x86/myxml_nomain.o build/DebugDynamic/GNU-Linux-x86/ClientSocket.o build/DebugDynamic/GNU-Linux-x86/FFJSON.o build/DebugDynamic/GNU-Linux-x86/JPEGImage.o build/DebugDynamic/GNU-Linux-x86/ServerSocket.o build/DebugDynamic/GNU-Linux-x86/Socket.o build/DebugDynamic/GNU-Linux-x86/logger.o build/DebugDynamic/GNU-Linux-x86/myconverters.o build/DebugDynamic/GNU-Linux-x86/mycurl.o build/DebugDynamic/GNU-Linux-x86/mystdlib.o build/DebugDynamic/GNU-Linux-x86/myxml.o -lxml2 -lpthread -lssl -lcrypto -lz 

netbeans为项目中的每个目标文件都包含一个重复的目标文件_nomain.o。

ClientSocket.h
