Update problem with FreeLSS 1.26 (Page 1 of 4)

Hey Joe, I had the same problems.  Here's how I got to 1.26 by trying a combination of things already on the forum:
Forget stretch, there seem to be some incompatible libraries used.  Go here http://downloads.raspberrypi.org/raspbian/images/ download raspbian-2017-07-05 which is the final version of raspbian jessie.  Install and do as before to get v1.11 running.  Update to v1.26 but it still wont be working yet.  Then downgraded kernel to ver. 4.4.50 by using:

sudo rpi-update 52241088c1da59a359110d39c1875cda56496764

type:

ldd /usr/local/bin/freelss 

This is a long list of freelss libraries.  look for => not found eg. libpng12.so.0   Need to install missing libraries- I had 4 missing.  There is a tool.  Type:

sudo apt-get install apt-file
sudo apt-file update

we can use apt-file to search for missing libaries eg.

apt-file search libjpeg.so.8

gave me the library name libjpeg8.  When you have all your missing library names use apt-get install eg.

sudo apt-get install libjpeg8 libopencv-core2.4 libopencv-calib3d2.4 libopencv-imgproc2.4

browse to the install location of v1.26 and run:

cd /opt/freelss-1-26
sudo ./freelss

I haven't yet figured out how to get freelss to auto start as sudo - the script provided doesn't give freelss full write access so it can't edit the config files.  But its definitely v1.26 running on my machine.  Hope this helps

hairu526 where are you? no posts for 3 months now. still need help logging into scanner as nothing does it anymore. last time I did was over a year and half ago. all I get is a few flickers of the pi LEDs and time outs no matter if direct connect or WIFI.

there are 2 newer zip files on that site now and it took me an hour with high speed internet to download latest one 2018-04-18-raspbian-stretch.zip as its near 2GB yeah why so big for such a tiny pi? is it everything due to him leaving the scanner project?

its an image file that wont fit on a CD or most older SD cards so how can pi read it? with tiny memory

It's the entire OS and files the Pi needs to boot, and run. It is an image file that you use a program such as Etcher to write to an SDcard. This would be the image file I was talking about in the other thread. Minimum cards size would be 4GB.

cool will it work still on the old pi B like mine? or do some of those files only work on pi2/3?

I would assume it would be backwards compatible unless it is noted on the site somewhere the hardware has been upgraded. The worse it will do is not work. Everything stays on the card so once the card is removed nothing remains of that OS. I could technically send you my card for Pi that runs NanoDLP on DUV printers and your Pi would boot and load up NanoDLP and the Linux OS it runs on.

Oh and while we are on the topic of the card, Because it holds and runs the OS from the card it is absolutely necessary for the card to be a Class 10 card. Anything else is too slow. This could also be part of your slow boot issue.

when I put the SD card in my PC it asks if I want to format it? as it sees nothing
