Geogebra won't start: Missing a shared library

Ondra shared this question 5 years ago

Answered

I downloaded the Linux Portable package, but the executable it contains won't start:

% ./GeoGebra
./GeoGebra: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory

This is on a fully updated Fedora 25 Workstation. I do have the GConf2 package installed.

Some time ago, I used the “Classic” version of GeoGebra installed from the .rpm package and it worked great. So this problem is definitely new in the portable package.

Hi, I had the same problems with my computer 64 bit with (linux) Ubuntu 16.04. No problem with another linux computer 32 bit. ( I don't know if in italia it's working better with their 34 bit computers smile ).

The last linux portable : is : http://download.geogebra.or...

but the problem is the same.

I've tried a work around : add the different 386 libraries wanted in the error messages...

I don't know if they are the same with your computer, but for mine, I did :

sudo apt-get install libgtk2.0-0:i386
sudo apt-get install libxtst6:i386
sudo apt-get install libxss1:i386
sudo apt-get install libgconf-2-4:i386
sudo apt-get install libnss3:i386

and now, I can run the 6 portable versions for linux on my 64 bit computer.

Hi,

1) did you download the 6-0-355-0 or the 5-0-355-0 version ?

For the 5-0-355-0 it seems that the 29th row of the file : geogebra-portable

has to be replaced (not related to the version of the jre inside) by

export JAVACMD="$GG_PATH/jre1.8.0_121-$ARCH/bin/java"

2) your computer is 32 bit or 64 bit ?

Hi, the version is 6-0-295-0 – I don't see a download for 6-0-355-0 anywhere on the website. I did just download it today, though, so I would think it's the latest. My computer is 64-bit.

Version 5-0-355-0 works for me with the modification to geogebra-portable you mentioned.

Oh wow, that did fix that! I ran

dnf install GConf2.i686

and now version 6 starts for me as well. I would never have thought to check for 32-bit libraries. :)

Thanks for the help!

Thanks Michel for your information.

But I did your instructions sequence and I still had the non-start problem. I found that on my Ubuntu Linux 16.04 64 bits that an error occured when I tried this line : sudo apt-get install libconf-2-4:i386

I modified it for: sudo apt-get install libgconf-2-4:i386 and GeoGebra finally starts !

Thanks!

Thanks, i did a mistake doing the copy/paste : it was libgconf-2-4:i386 and not libconf-2-4:i386 as you noted, i'm going to modify my past post.

Re-Salut,

J'ai fait le commentaire en anglais afin qu'il soit plus universel ;-).

Merci!

Bye!

To run the GeoGebra 6 portable linux version on Ubuntu 16.04_2 and 64bits I've added to the list of the packages to add :

sudo apt-get install libx11-xcb1:i386
sudo apt-get install libasound2:i386
