<oriansj>lanodan: yeah cproc is starting to look very promising

<oriansj>muurkha: no worries, we all need reminders some days

<oriansj>with a bit more love, it'll probably become a very strong bootstrapping competitor to tcc

<oriansj>but yeah, any "simple" C or scheme or (insert language bootstrappable from assembly here) compiler able to build GCC definitely are interesting

<luke-jr>has anyone recently built Guix from source-only? getting stuck on Mes not building :/

<luke-jr>unhandled exception: unbound-variable: (export)

<luke-jr>during CC ../lib/linux/x86_64-mes-mescc/crt1.c

<stikonas>luke-jr: are you building mes manually?

<stikonas>or letting Guix build it?

<luke-jr>trying to, yes

<luke-jr>I don't have guix yet

<stikonas>if you build mes manually, then you need quite a few env variables

<stikonas>though mes won't be able to run buix

<stikonas>guix

<stikonas>I think you need guile

<luke-jr>well, what's the best approach to this?

<luke-jr>I have guile

<stikonas>have you exported path to nyacc modules?

<luke-jr>no, though nyacc is installed too :x

<stikonas>you probaby need to set GUILE_LOAD_PATH

<stikonas> https://github.com/fosslinux/live-bootstrap/blob/master/sysa/run.kaem and https://github.com/fosslinux/live-bootstrap/blob/master/sysa/mes-0.24.2/mes-0.24.2.kaem you can find some env variables needed to build mes

<stikonas>or to be more precise, to run mescc

<luke-jr>I'm not dead-set on the mes path, just thought that was "the way" to do this

<luke-jr>couldn't find a walkthrough outlining the process

<stikonas>well, live-bootstrap is basically a script to build gcc/guile/other things starting from nothing

<stikonas>you could try that

<luke-jr>but I have those things already, my goal is to get to Guix ;)

<oriansj>luke-jr: live-bootstrap is the one you probably want (guix includes things like a guile blob as a driver and some pregenerated files)

<stikonas>ACTION is running live-bootstrap on riscv64 HW for the first time

<stikonas>it's not fast though :(

<oriansj>well how many bogomips does the cpu cores have?

<oriansj>(a core2duo @2.4Ghz from 2008 is 4800.16 on a librebooted x200 for reference)

<stikonas> https://paste.debian.net/1287050/

<stikonas>it says 8

<stikonas>but probably that's just a fake number

<vagrantc>insufficiently bogus

<stikonas>I think on newer ISAs Linux does not calculate bogomips

<stikonas>I couldn't find any storage media to boot from...

<stikonas>but at least netboot worked

<oriansj>what does lscpu show?

<vagrantc>anyways, seems like some appluase is in order, yay!

<stikonas>oriansj: I don't have a booted system yet...

<stikonas>that's probably for tomorrow

<stikonas>for my first test I compiled linux kernel and netbooted kernel and initramfs with partial live-bootstrap image (no distfiles after tcc)

<oriansj>ah

<stikonas>yeah, it's slower than qemu...

<stikonas>so bootstrap to tcc will take hours...

<stikonas>maybe it could be a bit faster once I get heatsink...

<oriansj>is it an in-order cpu core? running at 100Mhz?

<stikonas>I thought it should be faster

<stikonas>than 100 Mhz

<stikonas>but yes, I guess in-order

<stikonas> https://www.cnx-software.com/2022/08/29/starfive-jh7110-risc-v-processor-specifications/

<stikonas>should be up to 1.5 GHz

<luke-jr>oriansj: but live-bootstrap doesn't end with a guix system, does it?

<oriansj>luke-jr: it could be as we bootstrap guile

<luke-jr>I have guile already tho

<oriansj>stikonas: looks like it is supposed to have up to 3840 DMIPS which puts it behind a PowerPC G4

<oriansj>and in comparison core2duo is 27,079 DMIPS

<stikonas>yeah, so I guess emulated core on amd64 is comparable to real riscv64 core

<stikonas>though that was user emulation

<stikonas>full system qemu would have been much slower

<oriansj>well assuming a 2-4x performance drop for virtualization

<stikonas>it's probably 10x or so

<stikonas>if not 20x

<stikonas>my riscv64 user emulated bootstrap runs for maybe 6h

<oriansj>an AMD Phenon II is 78,440 MIPS

<stikonas>but natively it can finish in 20 minutes

<luke-jr>oriansj: I have a fully installed and working system that I've already bootstrapped; the trouble is getting a Guix environment that can match hashes with normal Guix systems

<oriansj>luke-jr: ah, sorry for misunderstanding your problem

<stikonas>it's definitely more power efficient to run on real HW though....

<oriansj>yeah, 130 mW should definitely be much less than an x86 system (unless one has a Via C7M system)
