Hi Tom

BUMMER! (Flat-hand-against-my-forehead-effect!)...

Because in my question I asked something ARCHitecture related,
I tried to find a context there for "running Arch"...

I do not know archlinux, thats right...will check that!
Thanks for clearification!

Best regards,
Meino

Hi Alec,

Thanks for the information, which helps a lot! :)

I didn't understand the second sentence of you posting...
"running Arch"? What does it mean?

Thanks a lot for your help ! 8)

A quick scan of the datasheet reveals that this chip implements
ARMv5TEJ, so I'd guess go with the armv5tel stage3.

Unless you want to spend days installing/upgrading software, I'd suggest
running Arch, but that's just me.

[gentoo-user] Choosing the correct stage3 archive on ARM

2014-11-07 Thread meino . cramer
Hi,

for a little embedded system, which I want to set up with - of course ;) - 
Gentoo, I need a little help in choosing the correct stage3
image/archive (currently the board is on the way to me...).

The processor of the board is a AT91SAM9G25 (softloater, no FPU or
similiar) and the available stage3 images/archives are (as of my
knowledge):

lrwxrwxrwx1 1000 10008 Nov 08 00:30 current-stage3-armv4tl 
-> 20141026
lrwxrwxrwx1 1000 10008 Nov 08 00:30 current-stage3-armv5tel 
-> 20141025
lrwxrwxrwx1 1000 10008 Nov 08 00:30 current-stage3-armv6j 
-> 20141025
lrwxrwxrwx1 1000 10008 Nov 08 00:30 
current-stage3-armv6j_hardfp -> 20141024
lrwxrwxrwx1 1000 10008 Nov 08 00:30 current-stage3-armv7a 
-> 20141024
lrwxrwxrwx1 1000 10008 Nov 08 00:30 
current-stage3-armv7a_hardfp -> 20141023

The *hardfp* images/archives are not the correct ones...but the
armv thingy makes me a little nervous: Up to now I didn't find a
clue, of what version the AT91SAM9G25 is...

What stage3 I should use?

Thank you very much for any help in advance!
Best regards,
Meino

If I remember correctly (and I may not) the only thing I *had* to
rebuild was webkit-gtk with 4.8 as I was getting errors with apps built
with 4.8 and webkit-gtk built by 4.7.

But I tend to set up a @world rebuild to run when I'm not on my machines
if I have any issues anyway so I may not have run into other problems I
might have had otherwise.

Re: [gentoo-user] gcc 4.7.3 --> 4.8.3

2014-11-07 Thread Mark Pariente

so I'm still on 4.7.3; but if I set 4.8.3
as the default, should I rebuild @system ?

 # gcc-config -l
 [1] x86_64-pc-linux-gnu-4.7.3 *
 [2] x86_64-pc-linux-gnu-4.8.3


I saw the news item about 4.8.3-SSP, which I think is a good idea, but
how deeply, if at all, do I need to rebuild packages ?
Is there any special steps I should take now in prepartion for 4.9.x?
caveats?

@system ?
@world  ?
a specific list  of packages only ?


Based on my experience going from 4.7 to 4.8 was seamless, you can 
choose to not rebuild anything if you'd like. If you want to start 
taking advantage of -fstack-protector by default you can rebuild 
whatever you'd like, although if you're paranoid about security you 
should rebuild everything, ie. @system @world to make sure all your 
binaries and the libraries they dynamically load have the stack 
smashing guard built in.


Going to 4.9 though is another thing. Apparently they broke the ABI for 
the standard C++ library, so once you start compiling C++ stuff with 
4.9 you better go all in (I did @system @world with 4.9 and had very 
few things that failed to compile[1], it's looking pretty good already).
