On Ubuntu 64 bits and S4A

[jdelgado.pin]

Hi everyone,

I just got a working installation of S4A on Ubuntu 64 bit. Since some of you have been having problems with Ubuntu 64 I would like to tell you how I did it. I am NOT saying it is the best way to do it, nor that it is the right way to do it. It is just a workaround that, well, works :)

First download http://vps34736.ovh.net/S4A/S4A16.deb and uncompress it (*not* install it) somewhere. Let's call this place <somewhere>.

Then, for the sake of its dependencies, we will install scratch:
sudo apt-get install scratch

we will not do anything else with scratch. Surprisingly the module vm-display-x11 of S4A does not work in this setting (but the vm-display-x11 module of scratch works fine). After ldd'ing vm-display-x11 of S4A we see there is a library missing, so we install it:
sudo apt-get install libsm6:i386

Now, we should add our user (let it be <user>) to the group dialout:
sudo usermod -a -G dialout <user>

Finally, we can execute S4A:
<somwhere>/s4a_squeak_vm -encoding UTF-8 -vm-display-x11 -plugins <somewhere>/lib/s4a/Plugins/ -vm-sound-pulse <somewhere>/lib/s4a/S4A.image

It will find the Arduino board and we can play with S4A!

Now, a launcher should be created in the desktop but this is pretty much standard, so it will be left as an exercise for the reader... ;)

Let me say it again. This is only a workaround, but it works (in my machine :) )

Bests,

Jordi

Just a comment:

I do not know why Ubuntu is so problematic. In Linux Mint there was no problem at all. I just followed the instructions in the s4a.cat website after downloading S4A16.deb:

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install ia32-libs

sudo dpkg -i --force-architecture S4A16.deb



added user to the group dialout

sudo usermod -a -G dialout <user>

and everything works like a charm. Thus, other option would be to abandon Ubuntu and use Mint.

Bests,

Jordi

That's what I was going to say!

With Linux Mint 64 bits there's not problem at all with S4A...

Does not work with Ubuntu 14.0.4 64 bit

dpbkg: dependency problems prevent configuration of s4a:

s4a depends on libc6 (>=2.4).

s4a depends on libcairo2 (>= 1.8.6).

s4a depends on libglib2.0-0 (>=2.20.1)

s4a depends on libpango1.0.0 (>= 1.24.1).

s4a depends on libv4l-0 (>= 0.5.0).

Hope someone can help with this.

Hi!

Sorry for the late reply. Please try to execute these commands in a shell before installing S4A:

sudo dpkg -r s4a (Only if you have already installed it)

sudo dpkg --add-architecture i386

sudo apt-get update

Then install S4A:

sudo dpkg -i S4A16.deb

It should install automatically all dependencies needed.

Best regards,

thanks Victor or your reply.
I tried exactly what you stated and I get this.

I also saw your post here https://groups.google.com/d/msg/s4a-community/VRxkgF00BZI/NjFGAXrvBgAJ
and tried since the above did not work.

:s4a

dpkg --add-architecture i386

after that I got further, but got this error.

and if I try to run S4A
could not find display driver vm-display-X11; either:
  - check that /usr/local/squeak-3.10-4/lib/squeak/3.10-4/vm-display-X11.so exists, or
  - use the '-plugins <path>' option to tell me where it is, or
  - remove DISPLAY from your environment.

thanks. If I can't get it to work I will install CENTOS

[rashantha]

Hey guys so I finally got it install but doing a -f install on the remaining libs. But still can't run S4A I think it has an issue with Squeak which is 4.10.2 and S4A is searching for different plugin. Can't figure this out anymore.

Scratch runs but not S4A
scratch
Executing: /usr/lib/squeak/4.10.2-2614/squeakvm -encoding UTF-8 -vm-display-x11 -plugins /usr/lib/scratch/plugins/:/usr/lib/squeak/4.10.2-2614/ -vm-sound-pulse /usr/share/scratch/Scratch.image

I think S4A has to be pointed to 4.10.2-2614 instead of 3.10-4

TIA

[Víctor Casado]

Hi Rashanta,

S4A uses the original Squeak VM from the Scratch 1.4 version, not the latest one. Please can you send the output when you try to launch S4A from a terminal?

Thanks Victor

I did solve this issue. I will duplicate and create a blog with full instructions.

Hello
sorry for my english

if i go to /usr/lib/s4a and make 2click in s4a.image the program run perfectly

[rashantha de silva]

I believe I edited or moved the location of the file. It was that simple. I will look at my notes.  I had to figure it out myself and tried many things. A bit busy today but hopefully I will have some time to look.

Rashantha.

This solution is not working because there is no "ia32-libs" packet.
And I didn't find any solution for this problem. Thanks.

Installation troubleshooting

I can't install it on 64-bit Ubuntu/Debian

The Debian version of S4A is packaged only for i386 systems. To get it working in a 64-bit version, you need to follow the following steps (in a terminal, as root):

Fist of all, enable i386 packages and install ia32-libs

dpkg --add-architecture i386
apt-get update

apt-get install ia32-libs
Then install S4A:

dpkg -i --force-architecture S4A16.deb

[Víctor Casado]

Hi,

Yeah you're right, this workaround it's a bit outdated because there is no package ia32-libs anymore. These would be the correct instructions:

1. We need to know what libraries are needed. To check it, open a shell and execute the following command:

    ldd /usr/lib/s4a/Plugins/* | grep "not found"

2. Add the i386 architecture and update the packages (if you didn't before):

    dpkg --add-architecture i386
    apt-get update

2. Install the corresponding 32-bit libraries packages. You can search the contents of the packages from here.

For example, the next screenshot belongs to a freshly installation of Ubuntu 16.04.02:

That should be all :)

Best regards!
