Symptoms

An ICA Client used as a helper application or plug-in cannot be launched from Netscape 4.79/4.80 on AIX systems after logging onto a NFuse/Web Interface site.

Cause

Netscape uses some of its own versions of the system libraries and sets up Libpath so that these versions are referenced before the default system versions.

The Netscape script states that “tailored versions of the AIX libc.a library are designed to be run specifically with the Communicator product” and that users should not set their own Libpath to use these libraries.

The ICA Client experiences a fatal error when invoking the “select” system call through Netscape.

This is demonstrated with a test application that uses this “select” system call through Netscape.

Resolution

Use Netscape Version 4.79 with the IBM patch from ftp://service.boulder.ibm.com/aix/efixes/netscape/aix510/082002/README.html.

– OR –

Set LIBPATHibpath to /usr/netscape/communicator/lib510:/usr/netscape/communicator:/usr/lib:/lib. Note that /usr:/lib:/lib is the default setting for Libpath.

Creating a script to unset the Libpath should suffice.

1. Create a script, wfica.sh in $ICAROOT, as follows

#!/bin/sh
unset LIBPATH
exec $ICAROOT/wfica $*

Set ICA_PLUGIN=$ICAROOT/wfica.sh before running Netscape.

2. Rename $ICAROOT/wfica to $ICAROOT/wfica.exe.

3. Create a script, $ICAROOT/wfica, with the contents:

#!/bin/sh
unset LIBPATH
exec $ICAROOT/wfica.exe $*

The environment variable, $ICA_PLUGIN, does not need to be set.
