Pycom Firmware Tool error

[robertsehlstedt]

Hello!

I just got a pycom lopy4 and expansion board v3.1.
Followed this guide on how to install the Pycom Firmware Tool on my Ubuntu 18.04 LTS.

I installed dialog and serial using both pip and pip3. But I still get this error while trying to run pycom-fwtool.

robban-K56CB:~$ pycom-fwtool
pycom-fwtool: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

Any ideas of what could be going wrong? Where is this library supposed to be and why isn't it there? Can't find this error anywhere online.

@robertsehlstedt try:
sudo apt install libz-dev
in a terminal window to install libz.

@robert-hh Hi, I still get the same error unfortunately!

@robertsehlstedt Could you try: sudo apt-get install lib32z1

[robertsehlstedt]

@rskoniec This didn't remove the error itself, but instead changed how it looks. Now I get this:

robban-K56CB:~$ pycom-fwtool
Traceback (most recent call last):
  File "pycom_fwtool.py", line 28, in <module>
  File "/tmp/pip-install-GwIMLo/pyinstaller/PyInstaller/loader/pyimod03_importers.py", line 687, in load_module
ImportError: libxcb.so.1: cannot open shared object file: No such file or directory

@robertsehlstedt Try: sudo apt-get install zlib1g libxcb1

[robertsehlstedt]

@rskoniec I think it installed with the last command, because it's already installed with the latest version!

@robertsehlstedt What about libxcb1 package? Did you install it?

[robertsehlstedt]

@rskoniec Yes the latest version is installed!

[robertsehlstedt]

@robertsehlstedt It still doesn't work though, I should also say.

[robert-hh]

@robertsehlstedt Error messages are helpful. besides that, as just another blind shot you could try to install the build-essential package, although I hardly would assume that everyone else has installed that.

sudo apt-get update
sudo apt-get install build-essential

[robertsehlstedt]

@robert-hh Hey! I did provide all of my error messages in this thread, and the build-essentials were also already installed. I have no clue what's going on honestly..

[rskoniec]

@robertsehlstedt I've just installed Ubuntu 18.04 LTS on VirtualBox from this ISO with Minimal type and with Updates options checked during installation. On fresh system I've downloaded DEB file and from regular user account executed command: sudo dpkg -i pycom-fwtool-1.15.1-bionic-amd64.deb in the location where this file was saved. First execute of pycom-fwtool was successful with minor error (picture below).

But after this command sudo apt-get install libcanberra-gtk-module this error has gone (proof below).

So as you can see it should be pretty straightforward. ;o)

[robertsehlstedt]

@rskoniec I don't know what went wrong last time I installed it, but I followed these exact steps now and it worked fine :) Thank you a lot!

@robertsehlstedt You're welcome! :o)
