Hello, Yes, the final .9 matter... I have tested the binding on ArchLinux. And we have > $ whereis libvlccore libvlccore: /usr/lib/libvlccore.so and > $ whereis libvlc libvlc: /usr/lib/libvlc.so So two options, 1. I can add the version with ".9" in VLCLibrary>>#unix64LibraryName 2. Or you can create a link in ubuntu > ln -s /usr/lib/x86_64-linux-gnu/libvlccore.so.9 /usr/lib/x86_64-linux-gnu/libvlccore.so (please verity the command) In travis I'm doing ||dist: bionic |before_install ||- sudo apt install libvlc-dev libvlccore-dev| || || |And I have no problem.| | | | | |If you use a symbolic link and it works please let me know so I can add this step in the installation.| | | |Thanks for testing!| |BenoÃ®t | || Le 14/01/2020 Ã 19:05, Hilaire a Ã©critÂ : > Got an issue on Linux too (Ubuntu 18.04.03 LTS) > > See attached screenshot.

Got an issue on Linux too (Ubuntu 18.04.03 LTS) See attached screenshot. Does the final .9 in the installed library matter?

Hi, I am pretty flexible on time these days, except for next Friday afternoon/night and next Saturday (at GMT - 5). I already contacted the organizers to let them know that you may will be giving the talk (I talked about that possibility while applying). We can coordinate off-list. Just let me know your availability so we can figure out all details. Last version install instructions are here: https://mutabit.com/repos.fossil/grafoscopio/doc/tip/readme.md.html Cheers, Offray On 14/01/20 10:00 a.Â m., phil(a)highoctane.be wrote: > Can help too. > > Need correct version to demo as what I do have is old. > > Phil > > On Tue, 14 Jan 2020, 13:49 Santiago Bragagnolo, > <santiagobragagnolo(a)gmail.com <mailto:santiagobragagnolo@gmail.com>> > wrote: > > I am in.

Re: [Pharo-users] Pharo on OpenSUSE (FFI / libgit2 errors)

by Jan BlizniÄenko

The VM crash for Launcher is not caused by having different VM, but by using specific usage of SSL lib that does not work with this workaround. I added more details into new issue I created for vm: https://github.com/pharo-project/opensmalltalk-vm/issues/62 Jan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] Floating point arithmetic

by Bruce O'Neel

HI, I would upgrade that "a good read" to a critical read if you do anything with floating point. Â Floating point numbers are not real numbers but rather a small subset, and, have all kinds of funny properties. But we use them just like real numbers and that's what catches us out. cheers bruce > On Sun, Jan 12, 2020 at 02:13:00PM -0600, Donald Howard wrote: > > "What are other suggestions, workarounds or approaches community has?" > > This is a good read on the subject: > > https://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html > > Title is "What every computer scientist should know about floating point arithmetic". > > Pierce

Re: [Pharo-users] Pharo on OpenSUSE (FFI / libgit2 errors)

by Jan BlizniÄenko

Thank you for forwarding this. At first, I though "well, that is the same solution I posted in previous mail/post, you just have libs in different directory", but it is not. It creates link just once in lib64, not in each VM, which is way better (but has be done by root). Unfortunately, it does not work for Pharo Launcher on OpenSUSE - causes segfaults, don't know why. Usual VM is OK. Jan -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
