http://sourceforge.net/projects/gsoap2/
下载gsoap源码
解压：
$ unzip gsoap_2.8.17.zip
编译：
$ cd gsoap-2.8/
$ configure
$ make
$ sudo make install

Makefile文件

 #GSOAP_ROOT = /root/gsoap-2.7/gsoap
 WSNAME = add
 CC = g++ -g -DWITH_NONAMESPACES
 #INCLUDE = -I$(GSOAP_ROOT)
 SERVER_OBJS = soapC.o soapService.o $(WSNAME)Server.o
 CLIENT_OBJS = soapC.o soapProxy.o $(WSNAME)Client.o
 all: server client
 server: $(SERVER_OBJS)
     $(CC) $(INCLUDE) -o $(WSNAME)Server $(SERVER_OBJS) -lgsoapssl++ -lssl -lcrypto -lz
 client: $(CLIENT_OBJS)
     $(CC) $(INCLUDE) -o $(WSNAME)Client $(CLIENT_OBJS) -lgsoapssl++ -lssl -lcrypto -lz
 clean:
     rm -f *.o *.xml *.a *.wsdl *.nsmap soapH.h $(WSNAME)Stub.* $(WSNAME)server ns.xsd

编译：
soapcpp2 -i add.h
make

运行：
服务器
./addServer 9981
客户端
./addClient http://localhost:9981
以下是打印
Add100(10)=110
3 + 4 = 7
hello world
abcstruct:1 2.000000 a

其他一些总结：
如果自己写example程序,发现编译不过：
soapProxy.o：在函数‘Proxy::~Proxy()’中：
soapProxy.cpp:(.text+0x52)：对‘soap::~soap()’未定义的引用
soapProxy.o：在函数‘Proxy::reset()’中：
soapProxy.cpp:(.text+0xec)：对‘soap_initialize’未定义的引用
soapProxy.o：在函数‘Proxy::testChinese(char const*, char const*, char**)’中：
soapProxy.cpp:(.text+0x27a)：对‘soap_url’未定义的引用
soapProxy.o：在函数‘Proxy::Proxy()’中：
soapProxy.cpp:(.text+0x40d)：对‘soap::soap()’未定义的引用
soapProxy.cpp:(.text+0x44b)：对‘soap::~soap()’未定义的引用
soapProxy.o：在函数‘Proxy::reset()’中：
soapProxy.cpp:(.text+0xec)：对‘soap_initialize’未定义的引用
soapProxy.o：在函数‘Proxy::testChinese(char const*, char const*, char**)’中：
soapProxy.cpp:(.text+0x27a)：对‘soap_url’未定义的引用
collect2: error: ld returned 1 exit status

解决方法：
Makefile不用-lgsoap或者-lgsoapssl++方式链接gsop
而是直接把std2Soap.cpp 加入到工程中一起与自己的程序编译

gsoap下的samples示例工程
oneway  与心跳包有关
httpcookies  cookies有关

要支持SSl，GZIP，编译命令中加 -DWITH_OPENSSL -DWITH_GZIP -lssl -lcrypto -lz

中文乱码解决：
struct soap soap;
soap_init(&soap);
soap_set_mode(&soap, SOAP_C_UTFSTRING); // 程序中加这个

设置连接超时(秒为单位)：
soap->connect_timeout=3;

设置收发超时：
soap->send_timeout = 30;
soap->recv_timeout = 30;
