Can't open the program about cae HOT 26 CLOSED

Yes, the file is on my system ...

from cae.

Hi,
Are you using remote desktop connection? Python Xlib doesn't support it. In this case forget about this program.

from cae.

Hi,

no I am using native Ubuntu 18.04 LTS.

Thank you

from cae.

Please, check if Python Xlib is installed on your system with command:

pip install xlib

from cae.

Yes,

I had installed already: Successfully installed six-1.15.0 xlib-0.21

from cae.

Ok, then run command:
echo $DISPLAY
It should return something like ":0.0"

from cae.

Yes,

it returns :0.0

from cae.

Well, then I do not know. Sorry.
Try googling "Can't connect to display :0.0 No protocol specified"

from cae.

Thank you for your help. If I find a solution, I put here.

Another small issue, that I found was:

• when I run the ./cae.sh it gives the following message
  line 7: ../Downloads/cae-master/src/cae: No such file or directory

So I changed the src/cae in line 7 to cae.py, then it passes but gives the xlib problem

from cae.

Please, report if you'll manage to fix your system's configuration.
I understand the importance of user friendliness of the software. So, the program should be able to point to user where the problem is. But now we have what we have.

from cae.

I fixed the problem...

1. change cae.sh in line 7 and 11 to exec "$DIR/src/cae.py"
2. give permission to all files on the package to "allow this file to run as a program"
3. on terminal "xhost +"
4. run "./cae.sh"

It works perfectly, thank you

from cae.

No, do not change cae.sh! It shouldn't point to source file. It points to binary executable!
If you're trying to run program from sources - run command "python3 cae.py" from "src" folder.

from cae.

If you not change it, gives:

line 11: /home/cfernandes/Downloads/cae-master/src/cae -inp model.inp: No such file or directory

from cae.

So, that's the real issue!
Are you using sources or binaries? I'd recommend to use binaries. Download here:
https://github.com/calculix/cae/releases

from cae.

For everything to be clear I've updated "How to use" section in the README:
https://github.com/calculix/cae#how-to-use

from cae.

Thank you for your time, and sorry for for poor understanding of the program usage! Using the binaries the error is different: Fontconfig error: Cannot load config file from /etc/fonts/fonts.conf

from cae.

Looks like this is system problem, not CAE's.
The file must be present on system.
https://en.wikipedia.org/wiki/Fontconfig

from cae.

The only thing in CAE related to font is file:

https://github.com/calculix/cae/blob/master/config/Window.xml
font-family:'Ubuntu'; font-size:11pt; font-weight:400; font-style:normal;

Not sure this could be the reason of the problem.

from cae.

Please, could you attach file ./examples/default.log
It can contain some useful information.

from cae.

the content of default-log:

ERROR: ERROR! Can't get CalculiX GraphiX window.
ERROR: ERROR! Can't get CalculiX GraphiX window ID.

from cae.

Aha! That's what I'm working on right now. Wait for the next release. It'll be very soon.
Or you can checkout latest source code and use it instead of binaries - most of this problem is already fixed.

Thank you, I will wait for the next release.
Thank you for your work!

Dear imirzov,

unfortunately the new release keep the same behaviour on my machine. So, I assume that the problem is on my side. Thank you for all your work.

Dear Carlos,

Please, could you attach your ./examples/default.log from the new release?
