Esteban is on vacation and I’m not sure that he is reading emails. 
Now can you check the path that is used by the FFI call and put your path?
may be look at ffiLibrary and ffiLibrary:
I do not have an image with Mars at hand.

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

[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.

Hi kmo

Pablo is about to release a new VM this week or next week and your crash are 
interesting to us. 
I think that pablo will contact you.

 As I already described here:

 there is something weird on Pharo 8 (on Mac) because I'm running an

 I expected the same directory where there is Pharo.app

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

[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.

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

[Offray Vladimir Luna Cárdenas]

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 of  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] Intermediate-Level Tutorials for Pharo

[tbrunz]

I wrote a "theory of operation" document for my app, 
https://github.com/tbrunz/logic-puzzle

But then I realized, "Where do I put it??"

I thought of a few possibilities:

* Commit it to the git repo, but then it wouldn't be easy to access from
Pharo,
* Add it to a top-level Pharo class comment, 
* Make it into a string in Pharo, put it in a method in a class.

What's the standard practice for "attaching" non-code documents to Pharo
applications?

Thanks for the report I confirm that I can reproduce the problem.
