ZnInvalidUTF8: Illegal leading byte for utf-8 encoding while running Elegant Code image conversion example

by Offray Vladimir Luna CÃ¡rdenas

Hi, Today I was an introduction to Pharo. As usual, I asked the learner to taste the environment and syntax by running the examples in excellent Sven's Elegant Code[1] (BTW, can I translate snips ofÂ it to Spanish?). When she was adapting the example 6 about converting JPGs to PNGs, we get the error reported in this mail's subject. I tried running her example in my machine with her images and with my own and still I got the same error. What are we missing? [1] https://medium.com/concerning-pharo/elegant-pharo-code-bb590f0856d0 We are using Pharo 8.x on Manjaro Gnu/Linux 64 bits. Thanks, Offray

Re: [Pharo-users] Fuel - FLSerializer tests are not working (pharo 8)

by Denis Kudriashov

It can be a known issue with MacOS, the way how an operating system assigns a working directory for applications. For example starting an app using double click from Finder will use a root directory as a working copy. Davide how did you start the Pharo? Can you try to run it from the command line? In that case the current working directory of the terminal will be assigned to the started application. Ð¿Ð½, 3 Ð°Ð²Ð³. 2020 Ð³.

I still find it strange because Max and Martin are always taking care about fuel and I do not see them publishing a version for a new version with red tests.

Re: [Pharo-users] Pharo-Mars on Ubuntu

by kmo

The library not found problem has been resolved. We are now back to a VM crash when GTK is used. Pharo-Mars is still not running on Ubuntu. For those who want the details - The library problem was caused by Ubuntu not creating a symbolic link libGtk-3.so. It only has a libGtk-3.so.0 link. When I created the libGtk-3.so link, I got a VM crash when the image starts up. I see that Estaban has recently fixed the library issue by adding libGtk-3.so.0 to the library search path. He has also changed something in the startup of Pharo-Mars because I no longer get a VM crash when the Image starts up - I now get the crash when a GTK Spec application starts up. I'm just waiting for Estaban to update the issue to say he's had a chance to look at the crash. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
