When running CLI for EX12350 on Linux, I have this error:

/usr/sbin/cli: error while loading shared libraries: cannot open shared object file: No such file or directory


Made a search on Google about libprerrlog, I didn't find anything. Any idea how to run CLI for EX12350 managing now?

Hi Hung,

Kindly go to the link below to install CLI for EX12350.

Linux CLI 32 bit

Linux CLI 64 bit

Kindly make sure to use the compatible OS. Go to the link below to download the compatibility list.

Hi Hung,

Which Linix are you using, is it 32 or 64 bit? Also, did you recently upgrade your Linux? Did the CLI work before then stop working, or did it not work when installed? You need to give more details.

Be advised that the Ex12350 is long past EOL. The Stex driver is part of the Lunix kernel, but the GUI and CLI are not.

In another thread where the user had upgraded to Fedora 26, the installer would not work, I traced the missing libraries and installed those, then the installer would work, but the GUI still would not load. So resolving the issue may or may not give you a working CLI.

The Ex12350 software was not designed or compiled for the newer kernals. It was written for a v2.6 Kernel, and it's unlikely to work with a v4.x kernel.

There are two workarounds that I can see, manage from the BIOS, not ideal as you need to reboot but it's there.

The other workaround is to partition your disk to dual boot, and build the other partition with a compatible OS such as Fedora Core 5, probably any Fedora with a 2.6 Kernel should work. The Fedora Core 5 kernel is 2.6.18.

Thanks for replying. However, the reason is because you are mixing 32 bits and 64 bits app. Even I downloaded 64 bits CLI app, when running, I needed to install a bunch of 32 bits libs. It's working now.
