How to Prepare a Linux System for a Web Agent Installation

To prepare your Linux system for a Web Agent Installation, use the following process:

1. Verify that the proper Linux patches are installed.
2. Verify that the proper Linux libraries are installed.
3. Verify that the proper Linux tools are installed.
4. If you are using an Apache web server, compile it.

Required Linux Patches

The following Linux patches are required:

For Web Agents running on 64-bit Linux systems

• Binutils 2.17
• GCC 4.1.0

Required Linux Libraries

Certain library files are required for components operating on Linux operating environments. Failure to install the correct libraries can cause the following error:

java.lang.UnsatisfiedLinkError 

If you are installing, configuring, or upgrading a Linux version of this component, the following libraries are required on the host system:

Red Hat 5.x

compat–gcc-34-c++-3.4.6-patch_version.I386

Red Hat 6.x (32-bit)

libstdc++-4.4.6-3.el6.i686.rpm

To have the appropriate 32-bit C run–time library for your operating environment, install the previous rpm.

Red Hat 6.x (64-bit)

libXau-1.0.5-1.el6.i686.rpm

libxcb-1.5-1.el6.i686.rpm

libstdc++-4.4.6-4.el6.i686.rpm

Linux Tools Required

Before installing a SiteMinder Agent on a Red Hat Apache 2.2 web server running on the Red Hat Enterprise Linux operating environment, install all the items included in the Red Hat Legacy Software Development tools package.

Compile an Apache Web Server on a Linux System

For the SiteMinder Agent to operate with an Apache web server running Linux, you have to compile the server. Compiling is required because the Agent code uses pthreads (a library of POSIX-compliant thread routines), but the Apache server on the Linux platform does not, by default.

If you do not compile with the lpthread option, the Apache server starts up, but then hangs and does not handle any requests. The Apache server on Linux cannot initialize a module which uses pthreads due to issues with Linux's dynamic loader.

Follow these steps:

1. Enter the following:

   LIBS=-lpthread
   export LIBS
   

2. Configure Apache as usual by entering the following:

   configure --enable-module=so --prefix=your_install_target_directory
   make
   make install
