Application of Soap embedded Linux (i)

Simple Object access Protocol (SOAP) is a protocol specification for exchanging data, a lightweight, simple protocol that is based on XML (a subset of standard generic markup languages). It is designed to exchange structured and solidified information on the web.

This article describes the use of SOAP embedded Linux.

First, gSOAP

Reasons to choose gSOAP:

The gSOAP compilation tool provides a soap/xml implementation of the C + + language, making it much easier to develop a Web service or client program in the C/D + + language. The vast majority of the C++web Service Toolkit provides a set of API function class libraries to handle specific SOAP data structures, which makes it necessary for users to change the program structure to fit the relevant class library. In contrast, gSOAP uses compiler technology to provide a transparent set of soap APIs and hides content related to the development-agnostic SOAP implementation details to the user.

Portability: gSOAP supports most platforms, including embedded systems and small systems (such as embedded Symbian,palm). Portability test for Windows (98,xp,vista), Linux,unix system, Mac OS X,solaris,hp-ux,aix,freebsd,tru64,irix,qnx,vxworks.

Second, the transplant of gSOAP

1. Download the source code

http://sourceforge.net/projects/gsoap2/files/

Http://jaist.dl.sourceforge.net/project/gsoap2/gSOAP/gsoap_2.8.24r.zip

The download version for this example is: Gsoap_2.8.24r.zip

2. Extracting source code

$ unzip Gsoap_2.8.24r.zip

3. Compiling tools under x86 platform

Configure the source code

$./configure--prefix=/home/linux/gsoap/gsopa-x86

Configure some features, such as the target platform installation path, such as the configuration target platform is the x86 architecture, the installation path is/home/linux/gsoap/gsoap-x86

Compiling source code

$ make

Install Source to/home/linux/gsoap/gsoap-x86 directory

$ make Install

4. Compiling ARM Platform Tools

./configure--prefix=/home/linux/gsoap/gsopa-arm--host=arm-linux

Configure the source again, this time the target platform becomes Arm-linux

Modify the source code, according to the compilation error prompts to make the appropriate changes:

Modify the Config.h under the source directory

Comment out:

#define MALLOC Rpl_malloc

Soapcpp and WSDL2H generate co-workers during compilation The two tools are also used to generate some specific files at compile time, so if Soapcpp and wsdl2h are compiled into an arm architecture, they cannot be executed on the PC, which means that the resulting compilation cannot be completed. So here we choose not to compile these two files, and choose to use the corresponding files of the x86 schema produced by the previous section.

Modify Gsoap/src/makefile

Comment out

soapcpp2$ (Exeext): $ (soapcpp2_objects) $ (soapcpp2_dependencies) $ (extra_soapcpp2_dependencies)

@rm-F soapcpp2$ (Exeext)

$ (AM_V_CCLD) $ (soapcpp2_link) $ (soapcpp2_objects) $ (soapcpp2_ldadd) $ (LIBS)

Modify Gsoap/wsdl/makefile

wsdl2h$ (Exeext): $ (wsdl2h_objects) $ (wsdl2h_dependencies) $ (extra_wsdl2h_dependencies)

@rm-F wsdl2h$ (Exeext)

$ (AM_V_CXXLD) $ (wsdl2h_link) $ (wsdl2h_objects) $ (wsdl2h_ldadd) $ (LIBS)

Copy the Soapcpp and wsdl2h under the x86 schema to the project source directory:

$ cp/home/linux/gsoap/gsoap-x86/bin/soapcpp2/home/linux/gsoap/gsoap-2.8/gsoap/src/

$ cp/home/linux/gsoap/gsoap-x86/bin/wsdl2h/home/linux/gsoap/gsoap-2.8/gsoap/wsdl/

Compile

$ make

Installation

Make install
