The SAM framework and MQTT support can be built and used without any other prerequisites.
Support for protocols other than MQTT is provided via a set of libraries and some client
side code referred to as XMS.
If you only intend to use the built-in MQTT support then you can build and configure SAM as
an extension or simply refer to "php_sam.php" with a "requires" or "requires_once" clause
in your PHP script. In this case you need only install the code without building the
extension using the pear installer:
Linux installation steps
The sam extension is supplied as a PECL module, which
you should be able to download and install in one step as follows:
(Depending on your php environment, you will probably need to be root
to do this.)
Make sure that the module is loaded by PHP, by adding following line
to php.ini:
If you intend to use the XMS support to access the IBM Messaging and Queuing family
you must also enable the SAM XMS extension.
If you cannot use the PEAR installer, you can download the extension
and build it manually:
pear download sam #downloads sam-<version>.tgz
tar -xzf sam-<version>.tgz
cd sam-<version>
phpize
./configure
make
make install #you may need to be root for this step
To work with the very latest source, you'll need to extract it from
cvs and build manually as above.
Windows installation steps
You will probably need to build the sam extension for Windows as there
are only a limited range of pre-built binaries available from the SAM website.
The extension can be built using the standard Windows extension build procedures.
You will need the PHP source tree for the version of PHP you wish to
build the SAM extension against which you can obtain from php.net.
This should be unpacked into a working directory of your choice.
You will also need the libraries and headers used by PHP extensions
available from http://www.php.net/extra/win32build.zip and this
should be unzipped so that is in your working directory.
You should have something like:
c:\php-build\-
|
|---php-5.0.5--|---build
| |---ext
| |--- ...
|
|---win32build--|---bin
|---include
|---lib
You will need a compiler such as the free version of Visual Studio C++
Express from the Microsoft web site. Also you need the Microsoft
Windows Platform SDK which again can be downloaded from the Microsoft web site.
Obtain the SAM extension source using pear (pecl download sam) or by using
CVS and copy the files to a new "sam" directory under the "ext" directory
in your PHP source tree.
To build the extension open a build environment window by going to the
start menu->all programs->microsoft platform SDK for windows->
open build environment window->windows 200 build environment->
set windows 2000 build environment (retail)
This should open a command prompt with all the environment variables
set up to access the platform SDK etc. You then need to set the
environment variables for Visual Studio by issuing the command
"vcvars32.bat" in the window.
Change directory to your working directory e.g. cd c:\php-build. Then
make sure the win32build tools are accessible by adding them to the
PATH environment variable:
set PATH=..\win32build\bin;%PATH%
Run the buildconf.bat command. This should rebuild the configure.js
file.
Run the cscript command with the appropriate options. To build just the
SAM extension framework and MQTT support use:
cscript /nologo configure.js --with-sam
To build the SAM framework and the XMS support use:
cscript /nologo configure.js --with-sam --with-sam_xms="c:\program files\ibm\xms"
The additional parameter passed for sam_xms is the installation path to the
XMS libraries and runtime that were installed as described under prerequisites
at the top of this page.
You can specify whatever other cscript parameters you require to
include or exclude items from the php build or select options.
Assuming all has gone well so far you can now finally run a make for the SAM framework!
Also if you are using the XMS support you must make the sam_xms extensions:
If you have used Visual Studio 2005 to build the DLLs please see below for additional steps that
must be carried out before proceeding further.
The DLLs created (php_sam.dll and optionally php_sam_xms.dll)
can now be copied to the subdirectory appropriate for your PHP
set-up. Make sure that the module(s) are loaded by PHP, by
adding following line to php.ini:
If you intend to use the XMS support to access the IBM Messgaing and Queuing family
you must also enable the SAM XMS extension.
extension=php_sam_xms.dll
Additional steps for Visual Studio 2005
If you build the SAM extension with the Microsoft Visual Studio 2005
compiler and tools you need to perform an additional step in the build
process to ensure the php_sam.dll is able to link
with the C runtime libraries at runtime. This step includes the
dependancy manifest into the DLL. Switch to the directory where the
php_sam.dll has been generated (usually
Release_TS or Debug_TS below the php source directory) and issue the
following magic incantation:
mt.exe -manifest php_sam.dll.manifest -outputresource:php_sam.dll;2
If you are using the XMS capabilities you will need to do the same with the
SAM XMS DLL:
mt.exe -manifest php_sam_xms.dll.manifest -outputresource:php_sam_xms.dll;2
If you build the SAM extension using the compiler and libaries from
Microsoft Visual Studio 2005 you will also need to ensure that the
runtime components are installed on the system on which you intend to
use SAM. This can be accomplished by installing Visual Studio 2005 or
by using the freely distributable
» runtime package.
