Hi James,

Thanks for that.

Actually I got to know that it is possible to use chroot to compile.

I will try to compare different ways after my holiday ;-)

Hello Danny,

There was another gentoo wiki page, that I just ran across with many of
your (cross compiling) issues addressed, albeit for the Banana Rasp. Pi::

Why not just NFS-export your $PORTDIR to a chroot on your host machine, and 
build everything there? --sync takes quite a while, but that would easily be 
recouped in compilation. That's what I do with a little Atom N270 box here.

$ genlop -t gcc -f /mnt/atom/var/log/emerge.log | grep minutes
[...]
   merge time: 13 minutes and 11 seconds.
   merge time: 13 minutes and 35 seconds.
   merge time: 12 minutes and 51 seconds.

I do not really understand, since building on RPI takes so long compared
with PC, why do you still compile natively?
Is it because cross compiling will cause any bugs or failure?

I mean, even some packages will fail with cross compiler, it is still
possible to cross compile some *big* packages...

Sorry, to answer the question, the discussion was about the RPi3.
Maybe the poster was embellishing. Personal experience seems to
indicate it takes over a day but I never actually let a rebuild
finish.

I had to build some packages on device (RPi3), mostly the ones with
autotool configuration bugs. The longest ones were a few hours. Things
like GCC are massive outliers, and I don't think the runners up for
compile time even come close, unless you're compiling a DE suite.

The thing is I had to change my profile and toolchain a few times, and
if I was compiling it on device I would have wasted a week or more.

Also consider the availability of the parts you can buy like casings
and fans, when choosing a product.  Performance and support (kernel,
userland, etc.) should also be considered.

Being open-source looks advantageous, but how about the performance
compared to RPi3?

Also, was the one you tried RPi3?

Well, file server is only one of my use cases.

I would probably try to run a little server, or some little tricks I

I will have a look at BeagleBone.

Yes.

I briefly know how to install Gentoo on RPI, also I have used crossdev
before.

But...distcc was described as "not recommended" in the Gentoo
installation guide.
(Do not remember where exactly.)

So I did not really used that though.

If you want a decent fileserver I would advise getting a KCMA-D8 with a

Just to provide something yet another data point, at work I use Fedberry (a

although IIUC most people there use Raspbian.

The BCM2837 is a phone processor. If phones are not an embedded device
then I'm not sure what is. The RAM for the device is
package-on-package (i.e. high integration) and save the video outputs
most of the desktop-like ports (like the Ethernet port) are obtained
via hardwired connection to a USB adapter. The slow IO, limited
memory, and lack of general purpose communication interfaces besides
USB is what keeps it from being a good general purpose computer.

(Arguably the BCM2837 is intended for devices less complex than
phones, or precisely the kind of thing people call an "embedded
device.")

Following from the above, the devices were never meant to self-host
their OS and are very bad at doing so. All large projects I know of
lease time on powerful ARM servers to produce their packages because
doing it on the devices most people use the packages on is extremely
painful.

This situation really echoes the difference seen between content
producers and consumers when using desktops and phones. If you need a
device to run a simple server or act as a gateway then using
precompiled packages is fine, but if you're expecting to develop for
the device you need a separate computer to do most of your compilation
on.

Once you get a toolchain, though, compiling simple programs on your
device is fast enough to be reasonable. Things like GCC can take
nearly three days even on the Raspberry Pi 3.

My personal recommendation is that an interest in the ARM architecture
be pursued by purchasing an ARM server (or desktop). Anything else is
a waste of time and money. Some of them are starting to become
affordable, e.g. https://softiron.com/products/overdrive-1000/.

That's for sure, except... RPi3 is NOT an embedded device in any
traditional sense of the word and I don't really like the term extended
to such machines. Embedded is what I'd call a Cortex-M maybe, not some
general purpose Cortex-A quad core 64bit "beast" with full USB/HDMI and
OpenGL support. It runs circles around the first desktop  machine I
installed Gentoo on. It is roughly equal to your low end cheap Atom
type laptops as far as CPU performance is concerned. It just has a slow
I/O and less RAM than we consider the norm these days.

I see no reason to crossroot for it unless that's ones desire in itself
(for example when it works, it might be worth the time save for mass
testing of stuff, e.g initial arch team work), or you really need it
for some working linker memory limitations when trying to do some
desktop stuff (browser engines, rust). For headless cases, not worth
the hassle whatsoever imho. Yes, gcc itself will take half a day or
whatnot, but hey, it's just taking you some 3-5W chugging along.

crossdev sure, if you think with the limited I/O a distcc host can help
out.

But sure, it can be educational, so have at it if you want; when it
works, it'll get your packages done faster if you have a beefy x86_64.

If you want to use Gentoo on an embedded device you should be ready to
set up crossdev and a crossroot for it. This isn't hard.
Unfortunately, there are rather serious issues[1] in autotools that
prevent some packages from building with crossdev (code needs to be
run for various tests, but the tests compile it for the target system
- ARM - and try to run it on the host).

The packages that make up the stage3 image compile properly and large
packages like Perl and some others compile properly, but not
everything does and failures need to be fixed on a per-package basis.
I have a system and use it like this and it works fairly well. If you
want to use Debian or Arch one of the things you need to consider is
it will be much harder to get programs that are not already packaged
for you.


[1] An extremely interesting example is libidn2, where an autotools
test compiles a program to generate C code to be included in the
program: what is happening is a program generates a program to
generate a program to generate a program which is used by a program to
generate a program.

I have yet to use Raspbian. I have used mostly Arch and Gentoo

True for Rasp. Pi 1, not 3.  You can also just buy a spare [class 10]
Sd card, so you can try more OS.

(I compiled my packages with /var/tmp mounted as tmpfs, and used
https://github.com/raspberrypi/firmware for the kernel, modules and
firmware.  Having the self-compiled version doesn't always work and
takes time to configure.)

OK, I'll mention it. I generally use Raspbian because it just works. It
contains drivers for most of the 3rd party hardware and those that are
not included provide Raspbian installers or repos.

I generally use the lite version, which is just the core OS without the
desktop fluff, then add on whatever I need.

Re: [gentoo-user] Gentoo vs Raspbian on Raspberry Pi 3?

[Danny YUE]

Gentoo 64 bit was made working on Raspberry Pi 3 not long ago.

I tried Arch for a short time last year. I was really missing those USE
flags and ability to lock/select software version.

Also when I was using Arch, I always felt that it was pushing me hard to
upgrade my system, which really feels uncomfortable.

I think that Gentoo runs more stable than Arch (might be wrong, just my
feeling), and with cross compiling it should not be a big problem to
upgrade whole system.

I do agree that using Arch on Raspberry Pi would be much simpler than
Gentoo. Anyway I will try to compile natively after I receive my Pi ;-)

But till now nobody ever mentioned *official* raspbian OS. Funny.

The next time I use Gentoo I am planning have my build directoy on seperate
storage. I know I can cross compile, but building natively did not take as
long as you might think. If you are looking for similicty then try Arch.

Re: [gentoo-user] Gentoo vs Raspbian on Raspberry Pi 3?

[Herminio Hernandez, Jr.]

Well right now I am running Arch on my Pi mostly b/c when I was running
Gentoo I was compiling natiavly.  Arch has the benefit of running a minimal
install and you can basically build from there. I had some issues running
Gentoo, but that was mostly b/c I was building nativaly on the SD card.

[Danny YUE]

Any reasons? I want to hear some ideas to make the decision ;-)

Seriously, I do not think it is a good idea to compile using Raspberry
Pi because of the weak CPU.

I prefer to cross compile on my PC when using Gentoo.

I prefer Gentoo or Arch. With Gentoo consider making /var/tmp/portage on
USB drive. This way you have your build directory not on the SD card.

[gentoo-user] Gentoo vs Raspbian on Raspberry Pi 3?

[Danny YUE]

Hi guys,

I am planning to buy a Raspberry Pi 3 to setup a local network storage
and try some IoT stuff. Now I am searching for some background things.

Which OS do you install on your Raspberry Pi?

Gentoo? Raspbian? Or even...arch?

This might seems to be the wrong place to ask, but I consider Gentoo as
my first-place option, so I would like to know your experiences.

Thanks.
