Certain versions of the ZeroG installers have a serious issue when installing software on the Linux desktops. You start seeing a variety of errors like
"/bin/ls: error while loading shared libraries: librt.so.1: cannot open shared object file: No such file or directory"
... and many others, while you can very clearly see that the library files are present on the file system.
I face the same issue while installing Oracle Calendar desktop client on my FC 5 Linux distro. When i started googling for the errors encountered, i started to see a lot of rather half-answered posts which did not work for me. Sufficient enough to piss me off, i started debugging the installer by setting the debug param to true.
>LAX_DEBUG=1 sh cal_linux
This gave me some leads and i finally figured that there was some kind of work around being applied because the installer kept thinking that the JVM being used had a version less than 1.4, which was inturn caused by the fact that the installer was setting the LD_ASSUME_KERNEL variable to 2.2.5 ...
The version information was pulled of from a set of variables called v_major, v_minor, etc.. Fix these values and you are good to go :)
>v_minor=4 sh cal_linux
voila!! the installation goes through smoothly :)
If you would like to further customize the installation by specifying the JDK to be used, then you could achieve the same by the following command:
>v_minor=5 sh cal_linux LAX_VM /usr/java/jdk1.5.0_06/bin/java
Hope that helps you folks out there.
