This fails to build currently (possibly and upstream issue).

Update to 2.5 Final. http://wiki.qemu.org/ChangeLog/2.5

http://wiki.qemu-project.org/download/qemu-2.5.0.tar.bz2

from namcap: http://sl1pkn07.wtf/paste/view/ba9b6d23

qemu configure: http://sl1pkn07.wtf/paste/view/915d6b8d

build ok

Just a suggestion. Could it be possible to modify pkgver part ?

It will be more clear for users to know which version is built.

Using :

git describe --long | sed -r 's/^v//;s/([^-]*-g)/r\1/;s/-/./g'

instead of

echo "2.5.r$(git rev-list --count master).g$(git log -1 --format="%h")"

With the modified line : qemu-git 2.5.0.rc1.r21.g1aae36d-1 insead of qemu-git 2.5.r42520.g4b6eda6-1

Which one is simpler to understand ? :D

Well who would've thought that the culprit was using O3 in makepkg.conf .

Using O2 (default in Arch) solves the build issue for me .

Cheers !

Hi .

I still can't build this package . My Arch system is up to date as of today .

Error is :

Thank you in advance .

Also , I'm sure that it didn't fetch any new code from git before building trying to build , although 2.5 development has already started and there are a bunch of commits in the git repo .

Thanks .

Is this the problem you're talking about ?

strip "/home/fred/qemu-git/pkg/qemu-git/usr/bin/qemu-x86_64"
make: Leaving directory '/home/fred/qemu-git/src/qemu'

Yeah, no… I simply broke the build 5 days ago and tried to fix it with git push -f, but the aur4 doesn't do that. I'll change the version to 2.5 and fix it.

Maybe a little tweaking is needed as Qemu 2.4.0 is released and Qemu 2.5 development is opened ?
