06:34 AM Tom_itx is now known as Tom_L
04:14 PM jepler: at least this ARM is attached to a nice big heatsink and has a SATA connector (though it's hanging off an internal USB 3.0 bus) https://ameridroid.com/products/odroid-hc1-0003a (but little interest for LinuxCNC otherwise, no I/O headers that could possibly do realtime)
05:24 PM seb_kuzminsky: jan bit-bang spi out the sata port
05:24 PM seb_kuzminsky: jepler: i believe in you
05:25 PM CaptHindsight: seb_kuzminsky: working with your teensy-hal this weekend
05:25 PM CaptHindsight: using the A/D to read temperatures into HAL
05:33 PM seb_kuzminsky: CaptHindsight: i hope it works!
05:44 PM andypugh: Interesting. I bought one of these to have an easy-to-move dedicated LinuxCNC dev PC (it has p-port, PCI and PCIe). Tirns out it also has great preempt-rt latency, 5k unloaded, 17k loaded, That’s better than any RTAI machine I have had. http://www.ebay.co.uk/itm/RM-One-Ecoquiet-965-Intel-Dual-Core-T3200-2-00-GHz-All-In-One-PC-System-Grade-C-/121957176818?hash=item1c6536d5f2:g:9dUAAOSwKfVXEP3x
05:45 PM andypugh: It also has a neat set of rollers underneath so it spins on the spot, it was aimed at the edication market.
05:46 PM andypugh: They made just about the first PC I ever saw: https://en.wikipedia.org/wiki/Research_Machines_380Z
06:44 PM jepler: https://circuitbeard.co.uk/2017/08/28/tomy-turnin-turbo-dashboard-outrun-arcade/
06:47 PM andypugh: I played Outrun enough to get _really_ bothered by the way that the Ferrari logo got mirrored when you turned right.
06:50 PM jepler: I mostly played the pretty awful version for my home computer system https://youtu.be/KWhxVlOgjSc?t=100
06:52 PM andypugh: That still does it but it’s a one-pixel difference
06:54 PM andypugh: Actually a bit more at the base
07:00 PM andypugh: But that is pretty cool. But am I the only one thinking “I know how not to cut that corner” while reading the build log?
07:25 PM Tom_L: someone should post a link somewhere to the new git location. i've seen several looking for it in the other channel
07:27 PM jepler: Tom_L: go to linuxcnc.org and then click "source".
07:27 PM jepler: that link is in the upper right
07:28 PM Tom_L: he's looking for something in the compile source that moved i think
07:30 PM trentks: Hi, it appears that the git URL has changed from git://linuxcnc.org/git/linuxcnc.git to https://github.com/LinuxCNC/linuxcnc.git
07:30 PM trentks: I'm running arch, and in the AUR there is this package https://aur.archlinux.org/packages/linuxcnc-sim/
07:31 PM trentks: The PKGBUILD refers to the old url
07:31 PM cradek: yes we moved our git to github
07:31 PM cradek: please fix it if you can!
07:31 PM trentks: however replacing the line source=($_gitname::'git://git.linuxcnc.org/git/linuxcnc.git#tag=v2.7.8' 'boost.patch' 'image-to-gcode.patch' 'linuxcnc-sim.sh')
07:31 PM trentks: with source=($_gitname::'https://github.com/LinuxCNC/linuxcnc.git#tag=v2.7.8' 'boost.patch' 'image-to-gcode.patch' 'linuxcnc-sim.sh')
07:31 PM trentks: doesn't allow the build to continue
07:31 PM trentks: as the directory structures are different
07:31 PM cradek: hmm
07:32 PM trentks: specifically it fails with /linuxcnc-sim/src/linuxcnc/src: Not a directory ==> ERROR: A failure occurred in build(). Aborting...
07:33 PM cradek: we have never had a directory called linuxcnc-sim in git, so that must be something in the arch build
07:33 PM trentks: ah sorry that's where I've cloned the AUR pkg to
07:33 PM trentks: so really .../src/linuxncn/src: Not a directory
07:34 PM cradek: does the git clone work right? do you get a source tree?
07:35 PM Tom_L: i think it does, pretty sure i downloaded it after it moved
07:35 PM jepler: I recommend asking an AUR developer how to update the URL to work on github.
07:35 PM trentks: yeah but the PKGBUILD expects something different
07:35 PM cradek: I don't know anything about arch/aur so I can only ask about things you've probably already checked
07:36 PM trentks: I've left a request on the AUR but it should be a simple fix
07:36 PM cradek: I bet lots of packages point to github so I bet someone can help you
07:41 PM jepler: you want to try specifying git+https, with or without #tag=v2.7.8
07:42 PM jepler: https://wiki.archlinux.org/index.php/VCS_package_guidelines#VCS_sources
07:42 PM trentks: Ok, I'll give it a whirl
07:42 PM jepler: source=('project_name::git+http://project_url#branch=project_branch')
07:43 PM trentks: Ok, I'll leave it up to the AUR maintainer. Thanks for your help. I've got a linux mint box attached to my TV, do the package managers have a better linuxcnc support for debian based OS' / apt?
07:43 PM Tom_L: probably so
07:44 PM jepler: we build packages for debian (and some ooolllddd ubuntu versions) and try to support some debian-derived distros in our packaging, but it all depends on contributions from developers.
07:45 PM trentks: Ok, might just try getting her to go on that - wait for the AUR maintainer to work his magic.
