Installation broken on Ubuntu versions >=20.04 about esim

[saurabhb17]

yes of course, for Ubuntu 20.04 onward, we will use either evince or okular. Will be incorporated in next release

Ok thank you very much.
I have quite some trouble installing it in Ubuntu 20.10. There are more dependencies which are broken. Fixed most of them by hand editing the install-eSim.sh and install-nghdl.sh scripts...

---

Maybe these information help:
Broken dependencies that I remember:
install-eSim.sh:

• xpdf (at the moment I just commented these parts out, don't what will break)
• KiCad-4 (Installed official KiCad version from the Ubuntu repositories, don't know yet if it works with eSim at the moment)

install-nghdl.sh:

• llvm (oldest version available in Ubuntu 20.10 is llvm-8, also available are 9, 10, 11)

---

After "successful" installation the following error is thrown:

qwertz@hoth:~/VCS/ins_lectures$ esim
Traceback (most recent call last):
  File "frontEnd/Application.py", line 20, in <module>
ImportError: /tmp/_MEInyd3Cc/libz.so.1: version `ZLIB_1.2.9' not found (required by /usr/lib/x86_64-linux-gnu/libpng16.so.16)
[143781] Failed to execute script Application

Google brought me here https://ubuntuforums.org/showthread.php?t=2375927

cd /your_directory_software/../lib/ (the directory in which is present libz.so.1)
sudo mv libz.so.1 libz.so.1.old
sudo ln -s /lib/x86_64-linux-gnu/libz.so.1

but I couldn't figure out how to symlink a tmp folder which presumably is generated by the Application.py script.

You know, I have tried running eSim on Ubuntu 20 on a Virtualbox setup, surprisingly,I did not encounter the l_ibz.so.1: version `ZLIB_1.2.9_ issue.

Nevertheless, I will get back to you on this.

Manually installed xpdf from the 19.10 repos and then ran into not being able to install gnat-5 and couldn't find a way to do the same (lubuntu 20.04)

There is a new release that fixed all the above issues. It is available here. You can try it and let us know if there are any further issues.

[q-wertz]

Thanks for the new release :)

Aborting Installation...

Is it possible for you to use the new kicad version or are there API changes that you do not support?
I'm not a big fan of using python2 😅

Some modules of eSim and libraries were developed for old KiCad version. So, I highly doubt its compatibility with the new KiCad version. You can manually downgrade it to proceed with the old version. Otherwise, you can proceed with the new KiCad version (comment out the KiCad installation part in the script) and let us know if it works or not. You may also send a pull request for the same, and we shall make it available in our next release.

Regarding Python2, even I'm not a big fan of it, but it shouldn't do any harm to your usage of eSim.
