@MantaRayDeeJay it's like so that did not work the command "clear" ????
This is not a single screenshot?

@MantaRayDeeJay I do not think that the error in bCNC, the problem you have.
For some reason, you do not download the package.
By the way, the pillow V6 package is not in the Debian repository. Especially in your version.

@sfinexer I have checked that I have well downloaded the last stable armbian stretch version (v5.75) for my device (opi zero) but I will have to try with an older stable version (3.4 kernel) to see if it works better. Thanks for the tips.

@MantaRayDeeJay Download the archive as shown by the link and run bCNC. You obviously have a bug in the peripheral software and not in the bCNC target program.

What happens if you try to install pillow separately?

python2 -m pip install --upgrade 'Pillow>=4.0'

You can also try to uninstall the debian package, so there's no conflict with package installed by pip.

I repeat that there is probably somewhere you have a problem.

@sfinexer But have you tried on ARM system? It seems ARM packages have issues with compatibility, eg. #1063

Also check pip version by python2 -m pip --version
and try upgrading python2 -m pip install --upgrade pip

Please make sure there's enough free space at your raspi df -h

If none of this helps, you should ask Pillow developers to help you with installing on the ARM (raspi):

@Harvie Debian and its package versions are independent of the processor architecture. With some exceptions.
In this case, somehow it happened that the versions became confused.
I assume that as a novice user could temporarily change the system update settings previously. Thus, some packages are updated from the experimental branch.
Back versions of packages, debian is not able to return, only reinstallation of packages, and then errors are possible.

The current package base does not match any version of debian. Thus, there may be packet conflicts.

I am not talking about Debian packages. I am talking about PyPI. I've attached link to similar issue we had in past to my previous comment.

I must admit that if there is a mistake, it is clearly not with us.
Sometimes, to prove an error in the third-party software is difficult, even leaving patches.
The main reason is the lack of a primary developer, ie the one who originally made the program. And those who now support software sometimes do not fully understand the specifics of the work.
This may apply to both PyPI and another program.

Many of the errors that were in my own software, it was possible to reveal after years! The end user does not understand the specifics of the program, may accept the error as a certain functional feature, and not report it.

In the last screenshot you have the problem described. It needs zlib header files. Debian will probably call the package zlib-dev or something similar...

There is no binary package of pillow for ARM, so Pip is going to automaticaly build the pillow from sources for you. See the section "building from source" to get list of prerequisites for that:

@Harvie I have checked and I can find a zlib1g package in the list, is it different from zlib-dev ?
ZLib seems here

@Harvie I have found this French tutoriel for Raspberry PI which using the Raspbian OS. This device is based on an ARM SoC as my Orange Pi Zero (Allwinner H2+). I know there are some differences between Raspbian and Armbian but these two distro are based on Debian for ARM architecture, so I think if it works well with the Raspberry, I would be able to use it with an Orange Pi !!!

@sfinexer I have opened an issue with Pillow. Thanks for your tips.

and zlib1g ?

zlib1g-dev and zlib1g are two different packages. I have a repository like this.

@sfinexer zlib1g was already loaded in my linux distro by default, I think.

@sfinexer So now I have the 2 versions :

pizero@orangepizero:~$ sudo apt list --installed | grep -i zlib

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

zlib1g/stable,now 1:1.2.8.dfsg-5 armhf [installed]

@sfinexer I have solved the pb. with Pillow :

  • I need 2 packages sudo apt-get install python-dev python-setuptools
    https://pillow.readthedocs.io/en/latest/installation.html#building-on-linux
  • I need to add the --no-cache-dir option for pip2 because sometimes the installation crashes cause of out of memory (RAM). I have only 512MB on my OPi. It explains why I have had sometimes the error message killed during the install process
    sudo pip2 install --no-cache-dir --upgrade Pillow
  • Do not forget using sudo to full success the package install.

@sfinexer Now I'm trying to install bCNC but the process seems to be crached during the packages installation. I'm connected via SSH and the process animation seems to be stopped as a "freeze" for more than 20mn.

I try to install all other packages manually before installing nCNC (pyserial and numpy)
pyserial is OK

It seems that sometimes I mustn't use the "--no--cache-dir" pip option to install a package. A progress bar should be a useful help to avoid waiting a long time without to know if the process is crashed or not during a pip package install.
Work in progress... LOL

@MantaRayDeeJay Do you start everything?
Could not be somewhat short form, if possible, to describe what you think was problematic.

After installed the "python-tk" package, I can launch bCNC on my OPi zero 512 !

MantaRayDeeJay commented Apr 25, 2019

@sfinexer Summary :
To install bCNC on my OPi zero 512MB, I have done the following cmd :
apt
sudo apt-get install python-pip python-setuptools python-dev python-tk libjpeg-dev zlib1g-dev
pip

sudo pip2 install --no-cache-dir --upgrade 'Pillow>=4.0'
sudo pip2 install --upgrade 'pyserial<=3.0.1'
sudo pip2 install --upgrade 'numpy>=1.12'
sudo pip2 install --upgrade bCNC

Rem. 1 : installing numpy is particulary slow.
Rem. 2 : Sometimes, I need adding the "--no-cache_dir" pip option (for Pillow, if not, I have a killed error at 99%), sometimes I mustn't (for numpy, if not, the app install "freeze") to install well a module via pip.

I am really glad that you've managed to install this in the end.
I don't really know what to do about this.
Probably we should write some short installation manual, so other people can install it just like you did.
But still it seems to me that it's bit too complex. I wonder if there's easier way.
To be honest i've already lost track of all the stuff you had to do in order to install it. Can you please summarize it? Or maybe test it on fresh armbian install?

@Harvie I have tried to summarize it in my last message but I think it would be usefull to test it again on a new fresh armbian install as you suggest me !
Let me a bit of time to do it, I need to have a rest now ! it's tiring for a newbie in Linux environment !

@MantaRayDeeJay After you do the apt instal, in my opinion all of these commands:

sudo pip2 install --no-cache-dir --upgrade 'Pillow>=4.0'
sudo pip2 install --upgrade 'pyserial<=3.0.1'
sudo pip2 install --upgrade 'numpy>=1.12'
sudo pip2 install --upgrade bCNC

can be replaced by single:

sudo pip2 install --no-cache-dir --upgrade bCNC

There's probably some bug in pip, if this is not working, because it should install exactly these 3 packages before installing bCNC.

I've added the note about apt-get packages here:

@Harvie The problem is that pip seems not be very reliable with "low hardware setup". If I use the "--no-cache-dir" option, numpy installation "freeze". I will have to test it again later.

Can you please figure this out with pip developers? https://github.com/pypa/pip

Please let me some time, I'm working on other issues with my devices. (OPi WiFi cnx and CNC device usb cnx) I will be back later, thanks.
