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,

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 XILINX_PATH=/opt/Xilinx/Vivado/2020.2
export MATLAB_PATH=/home/kjwiik/.local/MATLAB/R2019a
export PLATFORM=lin64
export JASPER_BACKEND=vitis
XLNX_DT_REPO_PATH=/home/kjwiik/sandbox/xilinx/device-tree-xlnx
#export LD_PRELOAD=${LD_PRELOAD}:"/usr/lib/x86_64-linux-gnu/libexpat.so"
export CASPER_PYTHON_VENV_ON_START=/home/kjwiik/sandbox/casper-venv
----------------------------------------------------------------------
Any suggestions?
Thanks,
Kaj
