MATLAB: Does the installer give an error saying the directory jre does not exist on Linux

MATLAB

I downloaded the Linux installation files. When I execute the installer, I get the following error:

 The directory /home/user/Downloads/matlab-linux/sys/java/jre/glnx86/jre does not exist.

 The directory /home/user/Downloads/matlab-linux/sys/java/jre/glnxa64/jre does not exist ERROR: 
 After checking, it appears that the other directory exists.
 /home/user/Downloads/matlab-linux/sys/java/jre/glnxa64/jre
 OR
 /home/user/Downloads/matlab-linux/sys/java/jre/glnx86/jre
 How do I run the installer successfully?

Best Answer

This error can occur if you download and try to run the 64 bit Linux installation files on a 32 bit Linux operating system, or if you attempt to run the 32 bit installation files on a 64 bit linux operating system. To check and see if the version of Linux is 32-bit or 64-bit, run the following command in a Terminal:

uname -a

If you see i386 or i686, this indicates you are on a 32-bit version of Linux. If you see ia64 or x86_64, then this is a 64-bit version of Linux.

It is possible to install the 32 bit version of MATLAB on 64 bit linux - please see the related solutions below for more information.

MATLAB: Do I see the error: “java: not found” when installing a 32-Bit version on the 64-Bit Linux machine

This error suggestes that your distribution of Linux does not contain the 32-Bit binaries required to run the 32-Bit installer. If you're on an Ubuntu 64-bit Linux machine you can work around this issue by installing the package "ia32-libs" from your Linux distribution. Run the following command from Terminal:

apt-get install ia32-libs

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

After the binaries complete installing you should be able to run the MATLAB installer.

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

For more information on installing the 32-Bit version of MATLAB on your 64-Bit Linux machine, see the related solution: "How do I install 32-bit MATLAB on my 64-bit Linux machine?"

MATLAB: Do I receive an error message saying java not found during Polyspace installation on 64-bit Linux

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
