Just tried the image but I am having trouble with genup - here is what I get, typically:

Code:
pi64 ~ # genup
* Checking Portage configuration, please wait...
* Gentoo System Updater v1.0.24
* Updating Portage tree and syncing the eix cache
* (this may take some time)...
 * Syncing all portage overlays

 * emerge --sync failed
 * Time statistics:
    22 seconds for syncing
    25 seconds total

* genup: Error: Caught signal - exiting


I tried adding the IP for isshoni.org in my hosts file in case it was a DNSSEC issue, but it appears that while I can browse to isshoni.org, I don't see gentoo-portage-pi64-gem there.

Also tried manually starting rsyncd.

About the only thing I changed with the system so far was to change the timezone and locale. I did manually emerge layman because genup said layman -S was failing, appears that layman was not installed. Didn't really help though.

Thanks

modulo,

just tried this on a fresh copy of the image, connected via a mobile phone hotspot, and all seems to be working OK.

The rsyncd on isshoni.org (82.221.139.201) binds gentoo-portage-pi64-gem to the web directory served at https://isshoni.org/pi64-portage-gemato/

What do you get if you run:
Code:
pi64 ~ # emaint sync --repo gentoo
?

I have an odd issue with the latest genpi64. I'm trying to use `genup` and it appears to be working, but my X session went black with my mouse cursor still moveable. It used to be limited to a region of the screen but I deduced it was due to the screen locking. I entered my password and the mouse cursor could move around freely again, but my graphics won't come back yet. I opened tty2 and I can login just fine. emerge seems to be pegging my CPU and RAM use is sitting at about 700 MB on a Pi3B (128MB used for graphics) and the default 1G swap (that I plan to expand later), of which only 78MB or so are being used.

I don't really feel comfortable customizing this until it's up to date. Is there a way to do this without my graphics crapping out?

(In the middle of writing this, I noticed it moved on from the "--pretend --empty --verbose @world" stage to actually merging packages -- so maybe it's just super slow. I don't know if my graphics will come back or not.)

EDIT: Next morning, it's still going! 749 of 978 packages...

EDIT2: It completed, but I was unable to get the display driver back. I checked the last emerge log (forgot exact path atm) and it exited with status of 1. The only warnings I could find were typical ones like missing kernel sources, etc., since you don't really need them with a binhost-supported genpi64. At any rate, a reboot seemed to help things, when it struck me to check /etc/portage/make.conf for MAKEOPTS. Sure enough, the default -j5 -l4 was too much for my RPi3, so I lowered it to -j2 -l2 and turned a flashdrive into swap, so now things shouldn't be killed due to low memory.

We'll see how it goes when I need to compile something. I threw 16GB of storage at it, on a separate bus, so hopefully things will be better. :)

I'm looking forward to getting one of these https://www.raspberrypi.org/blog/8gb-raspberry-pi-4-on-sale-now-at-75/ I must say.

I've been able to migrate / adapt everything I need to use the pi4 as a desktop, but had to use zram to expand swap and even out the memory use. 4GB is just a touch underdone for an everyday driver, which I've been doing since January with very few issues.

Zram saves larger operations from hitting swap and has really smoothed out the operation of the system. It also seems to have completely resolved an intermittent issue I was having with chromium suddenly crashing when a number of tabs / windows were open for an extended period. It hasn't appreciably slowed the system and monitoring memory use, it seems pretty stable. Ram use jumps up to around 60% and rarely goes past 70%, almost no swapping.

An 8GB pi is going to be a pretty useful desktop replacement for general use, IMO, it's a real pity most won't experience Gentoo on it.

But power users, who want to be able to map all 8GB into the address space of a single process, need a 64-bit userland. There are plenty of options already out there, including Ubuntu and Gentoo.


That Gentoo link points to Sakakis genpi64 repo.
Well done Sakaki!

The news of an 8GB Pi is wonderful! You'll be able to host a minetest server, maybe render something simple in Blender, build Firefox without swap... it'll be nice!

Congrats on GenPi getting the recognition it deserves! There's better RelEng put into this than Gentoo itself imo.

Hello everyone,

Just curious if anyone has been able to get Rpi-play built on gentoo? https://github.com/FD-/RPiPlay

After running cmake, I get

Quote:
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
BRCM_EGL
linked by target "ilclient" in directory /home/pi/RPiPlay/renderers
BRCM_GLES_V2
linked by target "ilclient" in directory /home/pi/RPiPlay/renderers
OPENMAXIL
linked by target "ilclient" in directory /home/pi/RPiPlay/renderers

CMake Error at renderers/CMakeLists.txt:26 (add_library):
No SOURCES given to target: ilclient


CMake Generate step failed. Build files cannot be regenerated correctly.


Any ideas on how to fix this?

Thanks!

It looks like one of the requirements is raspberrypi-omxplayer (and there's an ebuild!) but that fails.

There's a fix on git for the problem I'm having here: https://github.com/popcornmix/omxplayer/commit/96800576209bbf02939a3d71dec91ec1c1da586b

So I've tinkered around a bit with repoman to have a modified ebuild (the -9999 version fails because of an old patch) but I keep getting ebuild.notadded

Any help would be greatly appreciated!
