Problem with plot in V 4.7

FreeFEM installation
1

Hello,

I installed the last version of FreeFem++ yesterday (V 4.7).
When I put a plot in my program no window appears any more to show the figure and the program stop running. Is there someone who could help me to fix this problem please?

Thank you.

Nabil

did you use the option “with graphics”:

FreeFem++ -wg your-code.edp

3

Yes they gave me the same problem.

4

Do you think that’s a problem related to my Mac version (Catalina 10.15.6)?

5

Most probably. You are using a very recent Xcode version that (I think?) none of us, the developers, are using. We will see the same problem with the official release of Big Sur, I guess?

6

yes it is the last version 12.0

7

So there is no solution for that?

8

Not yet. Use savevtk + ParaView.

9

Ok! I will try that.
Thank you so much for your help.

./ffglut -v /tmp/gg
