Which version of autogen ? Are these build errors preventing the package from
being installed, or are they merely errors ? The fact you are seeing a lot of
them suggests they're not fatal. Building 5.18.16-r1 with {-libopts and
-static-libs}, I get a few warnings on amd64, but nothing I would interpret as
severely unusual.
The build script is attached.

[gentoo-user] Anyone seeing tons of build errors while compiling sys-devel/autogen ?
Hi all, Just to make sure this ain't purely local: while building sys-devel/autogen, the build process shows a lot (really) of error messages from the compiler. Is there anyone seeing something like this? Thanks! Francisco Ares

Look into a pi-juice Hat or similar - it has a battery and can turn off properly either at low battery, or when power is removed. Alternatively, a pi is very low power anyway ... why not just leave it on in a featureless "black box" with no lights showing and program the remote to to do a fake "standbay/off" that triggers a script to blank the video and or reset the screen to the entry menu? (if you are like me, playing with the gear is way more fun than using it as a media box! :) I have a few different pi's and similar Odroid arm systems running Gentoo on sdcards - the failure rate is a real and constant problem (and seems worse on pi's no matter what brand/type of sdcard so keep an up to date spare+backups) and I am thinking of doing a disk-less NFS using the a minimal sdcard image. Has advantages in centralised management and using small cheap sdcards with possibly better performance. BillK pEpkey.asc Description: application/pgp-keys

E.g. openwrt. /root is actually a read-only squashfs image, and on top of that there's an overlay fs that uses a second partition as it's backing storage. This way, almost all of your system is purely read-only, but you have the ability to store changes to things you need to store changes for.

Seriously, pulling the power on an SD card has been known to corrupt it beyond recovery. BUT. Is the big worry that the home directory will get corrupted etc etc? I don't know if you can partition an SD card, but look at doing a kiosk-style install with the OS protected and read-only. Then look at sticking a loopback device on top of home, so that any changes exist only in ram, and are lost on shutdown. Hopefully, that means you now have a system that can boot and run off a write-protected SD card :-) Look at the raid wiki site https://raid.wiki.kernel.org/index.php/Linux_Raid#When_Things_Go_Wrogn and especially the stuff on recovering a damaged raid for info about how to set up loopback.

This is an appliance, the users merely turn it on and off. Administration would presumably be done remotely by the OP, for which Gentoo is well suited. However, that is probably about the only advantage of Gentoo here, your other points are so true.

Perhaps an easier solution, for the case of your parents, would be to find a simpler and smaller O.S.\ and then triage/fix the webcam and microphone problems. Aside from the perceived resolution of the webcam and microphone problems, are there any other significant reasons to use Gentoo ? Especially on a Raspberry Pi, it can be particularly difficult with the proprietary firmware. -- Ashley Dixon suugaku.co.uk 2A9A 4117 DA96 D18A 8A7B B0D2 A30E BF25 F290 A8AA signature.asc Description: PGP signature
[gentoo-user] Gentoo RPi boot to ram or read-only FS?
I'm building a video conference appliance using a Raspberry Pi 4 for my parents. I'm using a RPi 4 that boots from a SD card and an USB webcam/microphone. Gentoo is the only OS I can find that supports the USB webcam in both Firefox and Chromium with no issues. Getting my parents to understand that they need to shutdown the RPi before hitting the power button is a challenge. And I've not been successful at finding a case for the RPi 4 with a soft power switch and a fan. Does anyone have pointers for booting Gentoo in to ram? Or a mode with a read-only FS? Like the overlay mode in Raspbian? Thanks. Frank
