[S]Rebuild all packages that are already installed on system

[SeBO]

Hi
I'm playing - right now - with makeworld but - on this moment (it is still running) - it looks like it will build all packages from ABS(i mean this by saying ABS : https://github.com/archlinuxarm/PKGBUILDs) without checking that this package is necessary for me or not. I tried pacbuilder from svn but it didn't work for me (i had error: makepkg failed)

Edit:
Title is to long for [Solved] mark so I just added [S] as it.

[WarheadsSE]

Why?

[SeBO]

- because i found some flags for optimization and linpack shows that it is worth it to recompile libs and software, thats why.

i think you confused arch with gentoo.

[WarheadsSE]

So, for your individual system, you want O3, vfpv4 and mtune to a7?

You realize we can't do this distribution wide, correct. and that is why we've gone with the best possible lowest-common-denominator.

I am not saying this stops you from rebuilding the entire pile, but we can't as a distro, currently afford to keep armv7h, and a magic armv7hn(eon) floating around.

[SeBO]

Hey - guys I know that arch is not gentoo and i know you need to handle many other devices not only bpi (like in this case ).
Arch is so genius with pacman and other build tools that there is no competition for it and that is why i want to use arch (i have it on my laptop, i had it on my PC, i have it on my BannanaPIs [1 BPI-R1 and 4xBPI]) and i will use it till end of my days

I wrote little script to do rebuild (it is under construction so i think it will change soon - but right now it works as expected):

$this->bbcode_second_pass_code('', '
#!/bin/sh
REPOS=('core' 'extra' 'community' 'alarm')
NOT_IN_ARM_ABS_ARRAY=()
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
for repo in ${REPOS[*]}
do
echo '-------------------------------------'
echo "Trying to find package in $repo repo"
cd $repo
for packages in $(paclist $repo)
do
package_name=${packages%% *}
echo $package_name
arm_pkgbuild=$(find . -maxdepth 1 -name "$package_name" -type d)
if [ -z $arm_pkgbuild ] && [ ! -d ./$package_name ]
then
echo "No ARM PKGBUILD for $package_name - downloading from ABS with yaourt"
#NOT_IN_ARM_ABS_ARRAY+=($package_name)
mkdir $package_name
cd $package_name
yaourt -G $package_name
cd $package_name
makepkg --skippgpcheck --noconfirm -Ais
cd ../..
else
cd $arm_pkgbuild
if [ -d src ]
then
rm -rf src
fi
if [ -d pkg ]
then
rm -rf pkg
fi
makepkg --skippgpcheck --noconfirm -Ais
cd ..
fi
done
cd ..
echo '-------------------------------------'
done
IFS=$SAVEIFS
')

Oh, i forgot to mention that i use this script inside dir that comes after
$this->bbcode_second_pass_code('', 'git clone https://github.com/archlinuxarm/PKGBUILDs')
