HI @ebrahimraeyat
The problem is that the ubuntu gmsh package uses an old version of OpenCascade libraries (libooct 7.3) and FreeCAD uses a more recent version (7.5). That's why you get the messages about unmet dependencies.
The solution is to install gmsh directly from sources. You can try the bash script on the XC repository.
I think I can close the issue. If you have further problems don't hesitate to reopen.
Thanks, @lcpt. I am trying to install gmsh, but it gets me an error. I am finding the solution and didn't want to disturb you:

I can't find a solution for it. Thanks.
Hi @ebrahimraeyat
Maybe it's easier to download a precompiled version from the gmsh web page. Apparently there is a pip command that solves the problem.
Could you try this?
On the other hand; have you used ENABLE_MPI=0
?
cmake -DENABLE_BUILD_DYNAMIC=1 -DENABLE_FLTK=1 -DENABLE_MPI=0 ../gmsh'
see line 31 in gmsh_code_install.sh

Yes. I ran the script.
Hum, something is not working as intended.
Have you tried to install the binaries instead?
Yes, I installed it via pip3 install --upgrade gmsh
then link some files:
sudo ln -s /home/ebi/.local/lib/python3.8/site-packages/gmsh-4.8.3-Linux64-sdk/lib/libgmsh.so /usr/lib/x86_64-linux-gnu/libgmsh.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libgmsh.so /usr/lib/x86_64-linux-gnu/libgmsh.so.4.8
sudo ln -s /home/ebi/.local/lib/python3.8/site-packages/gmsh-4.8.3-Linux64-sdk/include/gmsh.h /usr/include/gmsh.h
the problem solved, but one test fail:
ERROR:root:test_shell_mitc9_02.py ERROR.
Good news! This test will sometimes fail, there is something wrong with the ShellMITC9 element, but it's not a systematic error (most of the time it works). This makes that error difficult to fix. I think that there is some value that is not initialized or something like this. I don't use this element at all, so I've postponed fixing this error.
Thank you so much @lcpt.
My pleasure!
I think we can close this issue.
Hi All. When I want to install dependencies in my laptop, It takes me this error:

I have been installed FreeCAD from source code, and this error appeared. Thanks.My machine:
