/usr/lib/x86_64-linux-gnu/octave/4.4.1/exec/x86_64-pc-linux-gnu/octave-gui: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

sudo apt-get install qt5-default
(didn't help)

greg@gcwarwar-w:~/octave$ octave

(now it works)

* *********************************


for octave, need to use

  graphics_toolkit('fltk')

running

  graphics_toolkit

shows that it is set to 'qt' by default


greg@gcwarwar-w:~$ cat .octaverc
% This File : ~/.octaverc

graphics_toolkit('fltk')

* Info on calling windows from wsl

  (as long as you're in a window directory, cmd.exe /c starts where you are)

For some reason I have a hard limit on the size in all the WSL flavors

ulimit -H -a  --> show hard limits

ulimit -S -a  --> show soft limits



In a normal linux distro, the hard limit for the stack is "unlimited"
For some reason in WSL, the hard limit is 8192
This causes a warning with running Vivado

For some reason when I simply do

su - greg


I now get a proper value of "unlimited" for the stack size
