Why do I receive an error message saying java not found during Polyspace installation on 64-bit Linux?

When installing a PolySpace product on a 64 bit Linux machine, the installation program ends with the error message:

 exec: 2433: /tmp/install.dir.880/Linux/resource/jre/bin/java: not found

The complete output of the installation process is:

 prompt> ./install.sh

 An error has occured and some files have not been installed. 

 Please check free disk space (almost 600MB are required to install all products). 

 Look at the log file for details. 

 In case of trouble with the main installer or java, 

 you can try to relaunch this script with -console.

This error occurs because the Polyspace installer is itself a 32-bit binary using 32-bit binaries, which may cause problems on a 64-bit machine. It needs 32-bit libraries installed.

On an Ubuntu 64-bit Linux machine, to work around this issue, install the package "ia32-libs" from your Linux distribution:

 apt-get install ia32-libs

Under most Linux releases, the command can be different. On a Red Hat 64-bit Linux machine, this installation can be accomplished by executing the following command in a shell:

 yum install glibc-devel.i386

Note that you need to be root to complete these steps.

Please refer to the documentation for your Linux distribution for more information on installing these libraries.
