Do you have the git library installed in your O.S.? if you read the stack trace, it's part of the initialization of git. libgit2_init On Sun, May 29, 2022 at 2:52 AM <mylists(a)posteo.de> wrote: > Hi, > > (Running GENTOO Linux 64bit/no 32bit layer) > > I just downloaded the Pharo Launcer and followed the instructions given > here: > > https://pharo-project.github.io/pharo-launcher/create-images/ > > I choose the newest stable image and launched it. > > A post mortem screen pops up (see attachment).

First time Pharo experience: TFFIBackend induced crash...

by mylists＠posteo.de

Hi, (Running GENTOO Linux 64bit/no 32bit layer) I just downloaded the Pharo Launcer and followed the instructions given here: https://pharo-project.github.io/pharo-launcher/create-images/ I choose the newest stable image and launched it. A post mortem screen pops up (see attachment). Since I just started with Pharo Smalltalk, i can only guess, that something with the âTFFIBackendâ (whatever that isâ¦ ;) ) failed and Pharo stopped working. I would like to use Pharoâ¦ How can I fix that problem? Cheers!
