安装
去官网拿到gsoap安装包。作者使用的gsoap_2.8.10.zip。
unzip gsoap_2.8.10.zip --解压安装包。
./configure --检查安装环境。 如果失败（出现error的），根据错误提示，安装相关的包。如果安装了openssl，还提示找不到-lssl，用root安装yum install openssl-devel（如遇其它，参考这篇博客http://blog.csdn.net/learnhard/article/details/5154262）
make --编译。
make install --安装。
记得多看看README NOTE INSTALL这些文件，别因为懒就不看。
安装成功后会出现打印如下提示
+--------------------------------------------------------+
| You now have successfully built and installed gsoap. |
| |
| You can link your programs with -lgsoap++ for |
| C++ projects created with soapcpp2 and you can link |
| with -lgsoap for C projects generated with soapcpp2 -c |
| |
| There are also corresponding libraries for SSL and |
| zlib compression support (-lgsoapssl and lgsoapssl++) |
| which require linking -lssl -lcrypto -lz |
| |
| Thanks for using gsoap. |

使用
mkdir soap --新建一个目录soap。
wget http://www.genivia.com/calc.wsdl --拿到测试用的wsdl文档，当然如果你有自己的文档更好，一样的。
/usr/local/bin/wsdl2h -c -o calc.h calc.wsdl --用wsdl2h工具将wsdl文档编译成calc.h头文件。
/usr/local/bin/soapcpp2 -Lc calc.h --将calc.h文件编译成为编程需要的多个文件，比如实现文件，xml样板等。
编写main.c
#include "soapH.h" #include "calc.nsmap" main() { struct soap *soap = soap_new(); double result; if (soap_call_ns__add(soap, 1.0, 2.0, &result) == SOAP_OK) printf("The sum of 1.0 and 2.0 is %lg\n", result); else soap_print_fault(soap, stderr); soap_end(soap); soap_free(soap); }
gcc main.c soapC.c soapClient.c $(安装包路径)/gsoap-2.8/gsoap/stdsoap2.c
主要就是这个stdsoap2.c文件，如果编译的时候不包含它，那么会有很多函数找不到实现。
