[casper] Simulink window does not open when Matlab is started by startsg

[Kaj Wiik]

Hi Casperites,

I am trying to install the RFSoC toolchain following the instructions from
https://github.com/casper-astro/tutorials_devel/blob/master/docs/tutorials/rfsoc/tut_getting_started.md

I am using Ubuntu 20.04 LTS, Vivado 2020.2, and Matlab 2019a (with Simulink)

The problem is that Simulink window appears if Matlab is started in normal 
environment, in python3 venv but _not if Matlab is started by startsg_.


The error message is:
-
Starting Vivado/Vitis Sysgen
Type xlDoc to open the Xilinx System Generator help documentation.
Type demo blockset xilinx to view the demos available for Xilinx System 
Generator.
Tip of the day: Learn more about Support for multiple clock domains.

I have tried to play with different libgmp versions as suggested by some 
Matlab/Xilings mailing lists but nothing has worked.


I ask in this list because this seems to be a casper toolflow related problem.

My startsg.local is

export MATLAB_PATH=/home/kjwiik/.local/MATLAB/R2019a

Any suggestions?

Thanks,

[Kaj Wiik]

Hmm, it seems that a window *is* opened but it is totally different than the 
normal Simulink window (looks oldfashioned with large fonts). Still, ideas how 
to get the 'correct' GUI window are welcomed.


Thanks,
Kaj

[Jack Hickish]

Hi Kaj,

Not sure whether it is at all relevant, but these days when faced with any
sort of probably OS/sysgen/MATLAB version combination issues I start
by installing the kde-full package.

I'll also add that I'm running MATLAB 2019a / Vivado 2020.2 without issue
on Ubuntu 18.04.

Cheers
Jack

I think that's pretty much what mine looks like. :)

Re: [casper] Simulink window does not open when Matlab is started by startsg

[Kaj Wiik]

Hi,

I installed kde-full but the error stays, maybe I should downgrade to 18.04...

On the other hand, if that Simulink window is good enough for you, then for sure 
it is good enough for me :-D! I guess that error message does not affect to 
other functionalities...


Thanks,
Kaj

Re: [casper] Simulink window does not open when Matlab is started by startsg

[Adam Isaacson]

Hi Kaj and Jack,

I am not sure if this helps or not. We use Ubuntu 18.04LTS, Vivado 2021.1
and Matlab R2019a. Sys generator is no longer available. It now uses the
Xilinx add on Model Composer. Wesley created a "startmc" file to fix this.
I know my startsg did not work. Try our repo:
www.github.com/ska-sa/mlib_devel (alveo_u50) branch, I think.

Try it and let me know. Ask Wesley for help if not. If this has nothing to
do with the issue then my apologies and sorry for leading you astray.

Kind regards,

Adam

Re: [casper] Simulink window does not open when Matlab is started by startsg

[Mitchell Burnett]

Hi Kaj,

For RFSoC as long as you are using Vivado <= 2020.2 you can still use System 
Generator with entry started using `./startsg`. Model Composer is replacing 
(really just wrapping) System Generator in future releases of Vivado/Vitis >= 
2021.

When setting up the RFSoC in the tools I know I tested it on Ubuntu 20.04, but 
I will admit I believe I may have gotten lucky by already having an Ubuntu 
environment I forced into working. It probably should have been tested from a 
fresh install with more information about what to do to start successfully.

Because your issue does seem familiar to me. I remember getting something very 
similar doing things with System Generator on an Ubuntu 20.04 machine before 
working on RFSoC. What I recall is that Vivado brings along with it in the 
installation a version `libgmp` that conflicts with what is distributed with 
base Ubuntu.

I would be curious to know what is returned if you run (from within your Matlab 
prompt)

`>> ! ldd /lib/x86_64-linux-gnu/libgnutls.so.30`

My suspicion is that you will get something returned where `libgnutls` is 
wanting to call something from `libgmp` that is being used from the Vivado 
installation that is the incorrect version, and subsequently fails out.

If this is the case then the way to go about fixing this is to move the 
offending libraries off the path, find the dependencies to replace them, and 
then install those. Obviously this comes at a risk of messing something up with 
your system, but if you are comfortable doing this sort of thing, you should be 
able to overcome it.

If I recall correctly, the missing dependencies are a set of the qt4 libraries, 
but Ubuntu 20.04 only qt5.

I may try to duplicate your problem to post the correct steps for RFSoC setup 
but if you would like to continue this let me know and we could work it out 
together.

Best,

Mitch

Re: [casper] Simulink window does not open when Matlab is started by startsg

[Kaj Wiik]

Hi Mitch,

(cc: to our local ZCU111 group)

Many thanks for reply, unfortunately I had to switch tasks and missed your mail 
at first. Because of that I reinstalled Ubuntu 18.04 to find that while simulink 
windows show up correctly, jasper_library errored with endless Python version 
problems. Fortunately at that (desperate :-)) moment I noticed your reply and 
reinstalled Ubuntu 20.04.


There is certainly something going on with library versions because when Matlab 
is started directly, simulink window appears without any error message. As I 
mentioned, only when started from ./startsg, the error appears.

So yes, there is a reference libgmp.so.10 => 
/opt/Xilinx/Vivado/2020.2/lib/lnx64.o/Ubuntu/libgmp.so.10.


If I set

export LD_PRELOAD=${LD_PRELOAD}:"/lib/x86_64-linux-gnu/libgmp.so.10"

in startsg.local then it linked to the system libgmp but unfortunately the error 
stays.


Because simulink works when Matlab is started directly, I think the correct 
libraries are there somewhere. It could of course be that QT4 libraries are 
needed because of dependencies in Vivado(/Matlab)?


I'd be very grateful for any suggestions. It is very encouraging to know that 
someone has got this combo working!


I am running on top of LXD containers so messing up the system is not a worry.

We could continue in slack if you'd prefer, not to trash the mailing list. In 
any case I plan to publish the correct recipe somewhere.


Thanks,
Kaj

Hi Kaj,

For RFSoC as long as you are using Vivado <= 2020.2 you can still use System 
Generator with entry started using `./startsg`. Model Composer is replacing 
(really just wrapping) System Generator in future releases of Vivado/Vitis >= 2021.
