Re: libgfapi on ubuntu

Hi Joe,

I've not had the problem you're experiencing. I have a little different process though.  I do all of image work and prep as root and then change owner when I'm ready to have it interact with qemu. I'm running glusterfs 3.4.1 on Ubuntu 13.04 using the build steps I've outlined below for Bernhard.  I've the insecure option enabled but I don't do any funky stuff with uid and gid at the gluster level.

Hi Bernhard,

I've had good luck building upstream using qemu from debian sid for ubuntu 13.10.  Rough steps to build follow 
#Make first rough attempt at getting build dependencies
apt-get  build-dep qemu 
# get almost all the rest and the tools to work up the debian magic
apt-get install devscripts quilt libiscsi-dev libseccomp-dev libusbredirparser-dev libssh2-1-dev libvdeplug-dev libjpeg-dev glusterfs*
# we need a newer version of libseccomp 
mkdir libseccomp
cd libseccomp
# grab it from upstream sid
wget http://ftp.de.debian.org/debian/pool/main/libs/libseccomp/libseccomp_2.1.0+dfsg.orig.tar.gz
wget http://ftp.de.debian.org/debian/pool/main/libs/libseccomp/libseccomp_2.1.0+dfsg-1.debian.tar.gz
# get it ready
tar xf libseccomp_2.1.0+dfsg.orig.tar.gz 
cd libseccomp-2.1.0+dfsg/
# install the debian magic
tar xf ../libseccomp_2.1.0+dfsg-1.debian.tar.gz
# apply series files if any
while quilt push; do quilt refresh; done
# build debs, they'll appear one directory up
debuild -i -us -uc -b
cd ..
# install it
dpkg -i *.deb
# qemu deps have been satisfied let's build
cd ..
mkdir qemu
cd qemu
# download our sources. you'll want to check back frequently on these for changes
wget http://ftp.de.debian.org/debian/pool/main/q/qemu/qemu_1.7.0+dfsg.orig.tar.xz
wget http://ftp.de.debian.org/debian/pool/main/q/qemu/qemu_1.7.0+dfsg-2.debian.tar.gz
wget http://download.gluster.org/pub/gluster/glusterfs/3.4/LATEST/glusterfs-3.4.2.tar.gz
tar xf glusterfs-3.4.2.tar.gz 
tar xf qemu_1.7.0+dfsg.orig.tar.xz 
cd qemu-1.7.0+dfsg/
# unpack the debian magic
tar xf ../qemu_1.7.0+dfsg-2.debian.tar.gz
# bring glusterfs in to the buiild
cp -r ../glusterfs-3.4.2 glusterfs
# the glusterfs check in configure looks around weird. I've never asked why but moving the src stuff up one works and tests fine
cd glusterfs/api/
mv src/* .
cd ../..
#you'll need to edit debian/control to enable glusterfs replacing  
##--enable-glusterfs todo 

#with the following

# --enable-glusterfs 
 glusterfs-common (>= 3.4.0),

#And finally build. It'll take ages.  http://xkcd.com/303/
# apply series if any
while quilt push; do quilt refresh; done
# build packages
debuild -i -us -uc -b
# You now have shiny qemu debs up a directory to install as you please with. 

Let me know if you have any problems.  Also have you tried out the new port option in 3.4.2 yet for migrations?

Hi Bernhard
(dropping -devel as I'm not subscribed)

I've been able to compile qemu using Ubuntu 12.04 and the OpenStack Havana cloud archive (https://wiki.ubuntu.com/ServerTeam/CloudArchive) which comes with its own version of qemu. Maybe you can just pull qemu from that repo without having to use 12.04.

If you do get qemu to compile, though, I'd be curious if you run into the issue described here:

http://www.gluster.org/pipermail/gluster-users/2013-December/thread.html#38302

I've been trying for weeks to clear time out to debug more, but just haven't been able to.

Thanks,
Joe

I'm running ubuntu 13.10 and try recompile qemu as described herehttps://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1224517
in order to test libgfapi.
unfortunately compiling failed with messages like this:
....

this both files are causing the trouble:

 /usr/include/fdt.h and
 /usr/include/libfdt.h

I tried the qemu sources from "trusty" (ubuntu 14.04) 
with them make failes with:
...

debuild: fatal error at line 1361:

....
anyone an idea how to proceed?

Since the above mentioned bug report is closed with "won't fix"
until there is a MIR filed for glusterfs I may ask
will that be done?
Otherwise how can I use libgfapi on an ubuntu system?
TIA
Bernhard
