mithroSelect "Vivado HL WebPack" (the free version)00:00
mithroWe only need the minimal features -- untick all but the following:00:00
mithroDesign Tools / Vivado Design Suite / Vivado00:00
mithroDevices / Production Devices / 7 Series /00:00
mithroHrm - build-essential shouldn't be needed for LiteX?00:01
mithroCarlFK: any idea who gurshaant malik is?00:02
mithroCarlFK: The instructions in the LiteX Build Env wiki started from https://docs.google.com/document/d/1b2rBju9Fxjlcv6y3Ib1WcrvmzPA63Pe-pnBaziJXZNY/edit?ts=5b7758fa#heading=h.uujg2q1gh2k7 and the older getting started docs at https://github.com/timvideos/litex-buildenv/blob/master/getting-started.md and https://github.com/timvideos/litex-buildenv/blob/master/doc/notes.md00:05
tpbTitle: FPGA Miniconf Set Up Instructions - Google Docs (at docs.google.com)00:05
mithroCarlFK: You might find that notes.md doc useful / interesting00:06
mithroCarlFK: Also https://github.com/timvideos/litex-buildenv/blob/master/doc/targets.md00:06
tpbTitle: litex-buildenv/targets.md at master · timvideos/litex-buildenv · GitHub (at github.com)00:06
CarlFKgurshaant malik - no, but it seems a little familiar00:07
mithroCarlFK: Have you seen https://github.com/timvideos/litex-buildenv/wiki/LiteX-for-Hardware-Engineers btw? It's written by Bunnie for people who are more hardware focused...00:08
tpbTitle: LiteX for Hardware Engineers · timvideos/litex-buildenv Wiki · GitHub (at github.com)00:08
CarlFKmithro: nope.  quick skim.. um... no time.  I've been being distracted all day, wanted to have gotten though your setup doc by now00:11

mithroCarlFK: It's more useful if you have people who say "I already know Verilog" -- point them to Bunnie's guide00:31
CarlFKmithro: I installed to "~/local/opt/"    I see /home/juser/local/opt/Vivado  - should I set export XILINX_PATH=/home/juser/local/opt/ or /home/juser/local/opt/Vivado ?00:31
mithrolet me look it up00:31
CarlFKIve tried both, and both times I get:     raise OSError("Unable to locate Vivado directory or settings.")00:32
mithroHrm....00:32
mithroXILINX_SETTINGS_ISE='/opt/Xilinx/*/ISE_DS/settings64.sh'00:33
mithroXILINX_SETTINGS_VIVADO='/opt/Xilinx/Vivado/*/settings64.sh'00:33
mithroXILINX_SETTINGS_ISE=($XILINX_DIR/$XILINX_SETTINGS_ISE)00:33
mithroXILINX_SETTINGS_VIVADO=($XILINX_DIR/$XILINX_SETTINGS_VIVADO)00:33
mithroSo - it's XILINX_DIR...00:33
mithroand it has to have /opt/Xilinx in it apparently?00:33
CarlFKsounds like I should install it again and this time to /opt/Xilinx?00:36
mithroSee "gurshaant malik"'s suggestion here -> https://docs.google.com/document/d/1b2rBju9Fxjlcv6y3Ib1WcrvmzPA63Pe-pnBaziJXZNY/edit?ts=5b7758fa#heading=h.kfga5xx9k89p00:37
tpbTitle: FPGA Miniconf Set Up Instructions - Google Docs (at docs.google.com)00:37
mithroCarlFK: If that works, then I'll accept it00:37
CarlFKmithro: what is realpath in "Install bash, wget and realpath. " ?01:01
mithroapt-get install realpath ?01:01
CarlFKmithro:  E: Package 'realpath' has no installation candidate01:08
mithrorealpath - coreutils realpath transitional package01:09
CarlFKnot sure it matters - yet - other things are erroring01:09
mithroLooks like it's in coreutils?01:09
CarlFKgot it. coreutils is already the newest01:09
mithro$ dpkg --listfiles coreutils | grep realpath01:09

CarlFKmithro: this looks like it wont' work: under "soft link your installation"  the 1,2,3 steps - step 3 - the link collides with step 2,01:38
CarlFKbut it only matters if you didn't follow the instructions above so *shrug*01:39
xobsI thought you just had to have the Xilinx bin directory in your PATH?01:51

CarlFKer wait.. missing dep01:54
CarlFKmake[1]: bison: Command not found01:54
xobsCarlFK: Is this on a Debian-like system or a Fedora-like system?02:02
CarlFKdebian - ubuntu02:02
xobsTry "apt-get build-dep qemu" to get all the dependencies.02:03
xobs(Perhaps a bit late for that now, sorry.)02:03
CarlFKheh - exactly the tangent I am on...02:05
CarlFKE: You must put some 'source' URIs in your sources.list02:06
CarlFKI know how to add them, but...02:06
CarlFKwhy aren't there there in the first place?!!!02:06
xobsI really wish they added them by default.  They're in your sources.list, but just commented out.02:06
CarlFKim sure an option in here will set them up when I build the box: https://salsa.debian.org/debconf-video-team/ansible/blob/master/roles/tftp-server/files/d-i/xenial/preseed.cfg02:08

CarlFKmaybe.  not happy about the u in udeb02:31
xobsudeb are micro-deb packages used for installation.02:32
xobsLikely, that is a configuration variable that targets the apt-setup udeb package that runs during installation.02:33
CarlFKyeah..02:37
CarlFKI'm tossing in a bunch of config lines to see what happens :p02:38
CarlFKok, back to installing yacc02:41
