Hello All, After many iterations of building Pillow from source, I think I have a solution that's working now. I have JTSDK Nix updated to do this when the user runs $(MAKE) for Debian 8.0 and Ubuntu 14.10 only. Later versions of Ubuntu do not seem to be a problem.
Windows seems fine sitting on v2.3.0, but, on the next JTSDK upgrade 2.0.1 or whatever it will be, maybe pushing up to / past Pillow v2.8.1 would be wise. In a nutshell, you should simply install whatever version of Pillow is in the repo for that distro. For Debian 8.0 and Ubuntu 14.10, that is v2.6.1 unfortunately. So the base packages are: ----- python3-pil python3-pil.imagetk python3-tk ----- After installing the base packages, add the required Pillow build dependencies, for Debian 8.0 (which works on Raspbian also) and Ubuntu 14.10, that would be: ----- libfreetype6-dev libjpeg-dev liblcms2-dev libtiff5-dev libwebp-dev \ libwebpmux1 mime-support tcl8.6-dev tk8.6-dev zlib1g-dev' ----- Following the dependency installation, install Pillow from the terminal using pip3: sudo pip3 install --upgrade pillow The --upgrade flag is important, as you would already have Pillow installed. You could specify a version if you wish, using pillow==2.8.1 for example, but I chose to let pip3 sort it out. After install/upgrade, rebuild WSJT or WSPR from the JTSDK build menu. I tested WSJT FSK441 wav files and left it in monitor with no failures. WSPR fires up and runs OK. I've not isolated the exact issue in v2.6.1, but it's only a problem long term for Debian 8.0 (Jessie) until the Pillow package is upgraded. At the moment, due to their pending release, pkg updates are in a freeze mode , unless it's deemed critical. Ubuntu 14.10 is a short term support release, end of life date is July 2015, and 15.04 is due out on April 28th I believe. If anyone has troubles with upgrading Pillow through JTSDK, just send a message to the devel-list, I'm sure we can get it sorted out. 73's Greg, KI7MT On 04/14/2015 05:59 PM, KI7MT wrote: > Hi Alan, > > I've not tried 2.6.2 as that version ins't in the Debian / Ubuntu repo's > but it is in PyPi ( via pip3 install): > > https://pypi.python.org/pypi/Pillow/2.6.2 > > I tried to stay with versions I could compare with Native packages, with > the exception of 2.5.3. > > Debian (8.0 Jessie) ==> Ubuntu (14.10 Utopic) is at: > > https://packages.debian.org/jessie/python3-pil v2.6.1 > > I've not tested the Raspbian (8.0 Jessie) on the RPI2, but their > packaging seems to follow closely with Debian core, apart from the > Raspbian specific components. > > > 73's > Greg, KI7MT > > On 04/14/2015 04:42 PM, Alan VK2ZIW wrote: >> Hi Greg, >> >> Fedora 21 now cones with: python3-pillow.armv7hl 2.6.2-1.fc21 >> >> So, does 2.6.2 work? >> >> I'm not sure as I've upgraded "pillow" using "pip" to 2.7.0. >> >> /usr/lib/python3.4/site-packages/Pillow-2.7.0-py3.4.egg-info >> >> Today, I did a "yum update" and I now have >> /usr/lib/python3.4/site-packages/Pillow-2.6.2-py3.4.egg-info >> dated Apr 15 07:20 >> >> Today, >> "wsjt10" runs fine via RDP session, (headless, there is no Mali driver yet) >> >> Back on Jan 15, there was, when the Banana Pi was loaded, "pillow" 2.6.1. >> >> Keep Smiling >> >> Alan VK2ZIW >> >> >> >> On Tue, 14 Apr 2015 10:50:28 -0600, KI7MT wrote >>> Hello All, >>> >>> While updating WSJT/WSPR build documentation, I've come full circle >>> on the Python3-Pillow 2.6.1 segfault problem that many have >>> reported.
