Linux 下 gsoap 的使用及移植 1、下载 gsoap 在 gsoap 的官网中可以找到最新的 gsoap 安装包及相关文档 gsoap 官网：http://www.cs.fsu.edu/~engelen/soap.html 下载地址：http://sourceforge.net/projects/gsoap2/files/ 2、安装 gsoap a、解压 zip 压缩包命令：unzip gsoap_2.8.1.zip b、进入解压后生成的文件夹 gsoap-2.8 命令：cd gsoap-2.8/ c、切换到 root 用户命令：su 输入密码 d、配置编译环境在 gsoap-2.8/文件夹下执行 configure 文件，自动配置编译环境命令：./configure e、编译连接命令：make f、安装 gsoap 命令：make install 安装完毕可用 wsdl2h 或 soapcpp2 查看 gsoap 是否已经安装成功看到上述两个命令的返回说明安装成功 3、应用实例 wsdl2h -o outfile.h infile.wsdl 实现 wsdl 文件到 h 文件的数据映射 soapcpp2 -c outfile.h 生成相应的底层通信 stub，strech 程序首先新建一个文件夹名为 gsoap；然后 (1) 不使用 wsdl2h a、不使用 wsdl2h 我们可以直接从.h 文件来生成代码。我们先定义一个函数声明文件，用来定义接口函数，名称为 add.h，内容如下： //gsoapopt cw //gsoap ns2 schema namespace: urn:add //gsoap ns2 schema form: unqualified //gsoap ns2 service name: add //gsoap ns2 service type: addPortType //gsoap ns2 service port:http://websrv.cs.fsu.edu/~engelen/addserver.cgi //gsoap ns2 service namespace: urn:add //gsoap ns2 service transport: http://schemas.xmlsoap.org/soap/http //gsoap ns2 service method-style: add rpc //gsoap ns2 service method-encoding: add http://schemas.xmlsoap.org/soap/encoding/ //gsoap ns2 service method-action: add "" int ns2__add( int num1, int num2, int* sum ); b、执行 soapcpp2 –c add.h,自动生成一些远程调用需要的文件 c、接下来写一个服务端，创建文件 addserver.c

(pietty 的设置方法，option->Encoding->Unicode utf-8) 4、移植关于 gsoap 程序的移植很简单只需要将编写完成的程序用交叉编译工具生成可执行文件下载到目标板上即可。
