Hi,

I'm trying to run a 32 bit application (dropbox portable) on 64 bit Mint, but it fails with this error

Code: Select all

./dropboxportable: error while loading shared libraries: libfuse.so.2: cannot open shared object file: No such file or directory
Is there any way round this?

why not just run 32bit mint ? it is PAE enabled and detects more than 4GB ram.

or open synaptic manager and look for "libfuse" and see if its there and install it ?

It can't possibly address over 4GB, which is the maximum that a 32bit system can address.

Read here to have better understanding of how it all works and what PAE is : http://en.wikipedia.org/wiki/Physical_Address_Extension

It does. I am running 32bit Mate Nadia with 8GB ram installed and it shows and utilises all 8GB, Nadia is PAE enabled. You should read the release notes before you choose version to download :)

Release notes of Nadia :
PAE required for 32-bit ISOs

The 32-bit ISOs of Linux Mint 14 use a PAE kernel. If your processor is not compatible with PAE please use Linux Mint 13 Maya LTS instead. Linux Mint 13 is supported until 2017.

Yes, my error, but then what is the purpose of having a 64bit OS? Oh, and Linus frowns on PAE...

some people prefer 64bit maybe ?

Also for things like cad designers and such the 64bit os is prefered.

as for myself, I prefer 32bit for Wine. Wine and 64bit just is too buggy. Also, 32bit will run ALOT faster on 8GB ram than a 64bit will on 8GB ram :)

any particular reason he doesnt like PAE ?

After having been forced to work with HIMEM.SYS on DOS and Windows, he's right...

BTW, I was right too... No 32bit application can address over 4GB, even with PAE.

^ Thanks, but it didn't work. I got the same error.

^^ I'm running Mint off a Live USB stick with persistent casper-rw partition. I would happily use 32 bit Mint instead, I don't really need 64 bit, but how could I achieve this without losing all the customisations I've made stored in the casper-rw partition? I spent quite a while getting things set up the way I want and installing missing drivers etc.

wish i could help you there. I myself have re installed linux more than a dozen times over the last few months to get my desktop just right and apps working just the way i want them too. I have found no easy way to back up between installs. I simply made a list of everything i wanted to keep and then hunted down installers or links and made notepad files of instructions for stuff not in software manager, backed up my themes, aplets, extension folder, backed up my wine installers etc etc...

Was quite a job, but i have learned alot by doing it, i have a much better overview of file and directory structure now that i did not have before.

Maybe someone who knows linux better knows a quicker method ...

This MAY help you - it helped me to install Air/OLD Tweetdeck which are also only 32bit: http://jeffhendricks.net/?p=68

Thanks, but it didn't help. In the end I overwrote my 64 bit USB live key with the 32 bit version. Drastic..... but what the hell!
