Hello. I have downloaded the StarLogoTNG and I am trying to execute it.

I receive the following message

What should I try to do to skip this message? Unfortunately I do not know if there is the Java source and how it might be installed? Do you have any suggestions what I should try to do?
I would like to thank you in advance for your reply.

Looks like you downloaded the wrong executable for your computer.

The message "wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)" suggests that you might be trying to run a 64-bit application on a 32-bit machine or vice-versa.

If your machine has a 64-bit processor, try downloading the 64-bit version of the executable and try. On the other hand if your machine has a 32-bit processor, try running a 32-bit version of the executable.

Search the internet for "wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)" and see if you get any hits to forum that talk about this problem for your software.

Thanks for your kindness to help me....
What seems strange to me is that I am running a 64 bit version of Linux.
My processor is the Core 2 Duo and my kernel is the

uname -a
1 SMP 2010-01-27 08:20:11 +0100 x86_64 x86_64 x86_64 GNU/Linux


which probably means that I am running a 64 bit version operating system and in that sense the 32 bit software version should be running properly

I would expect so. But the exception is clearly indicating otherwise.

In the error message that you posted initially it suggests that "starlogotng_1.0_i386/build/libStarLogoC.so" was built for i386 architecture. So I am not sure whether this library is playing nicely with x86_64 kernel!?!?!

Another thing to check - is the JVM and JDK built for 64-bit kernel?

Problem solved. Just removed all java related 64bit stuff and replaced them with the 32bit versions.
Now it works nice
