Installing or running SAMSON on Ubuntu 17.04 and later versions

Hi @Subhajig ,
What Ubuntu version do you have?
Do you have an Nvidia GPU? You can check it with the following command in the terminal:

lspci | grep VGA

Thanks for quick reply,
My UBUNTU version is 16.04.4 LTS.
After giving "1spci | grep VGA" i'm getting following
"00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)"
Thanks in advance.

It seems that your system does not have a dedicated GPU. You should be able to run SAMSON with Intel (with built-in graphics), but you may lack some SAMSON features, which relies on GPU.

Could you, please, check the result of the following command in your terminal:

glxinfo | grep OpenGL

If you see "The program 'glxinfo' is currently not installed", you will need to install the mesa:

sudo apt-get install build-essential mesa-utils libgl1-mesa-dev

After the installation, try the glxinfo | grep OpenGL command again in the terminal.

Hi,
Sorry for delay.After installing mesa also I'm getting same error.Please give some suggestions to avoid this issues.
Thank in advance

Please, post the output of the following command:

glxinfo | grep OpenGL

Subhajig · Mar 7, 2019, 4:32 PM

I'm getting following

Could you please run the following command in the terminal and post it here:

locate libOpenGL.so

If you see in the result, for example, /usr/lib/x86_64-linux-gnu/libOpenGL.so but no libOpenGL.so.0, you will need to create a symlink.

Subhajig · Mar 7, 2019, 5:08 PM

Hi,
Thank you for your reply.Could you please tell me how will I create a symlink.

DmitriyMarin · Mar 7, 2019, 5:16 PM

Does the command locate libOpenGL.so show you libOpenGL.so or not?
The symlink can be created in the terminal as follows:

ln -s target linkname

Subhajig · Mar 7, 2019, 5:19 PM

After giving command 'locate libOpenGL.so' i'm not getting any output.

@Subhajig

Could you, please, double-check whether libgl1-mesa-dev is installed:

sudo apt-get install build-essential mesa-utils libgl1-mesa-dev

Please, check the troubleshooting section of the SAMSON Installation guide.
You can do a symlink to the libQt5OpenGL.so shipped together with SAMSON:

ln -s $HOME/NANO-D/SAMSON/0.7.0/Binaries/SAMSONQtLibs/libQt5OpenGL.so $HOME/NANO-D/SAMSON/0.7.0/Binaries/SAMSONQtLibs/libOpenGL.so.0

or you can install compiz and create symlink to its OpenGL:

sudo apt-get install compiz-dev
sudo ln -s /usr/lib/x86_64-linux-gnu/compiz/libopengl.so $HOME/NANO-D/SAMSON/0.7.0/Binaries/SAMSONQtLibs/libOpenGL.so.0
