Compile 32bit WINE in 64bit CentOS 7

Leave a comment

I was dismayed to find out that you can’t run 32 bit windows programs in 64bit CentOS 7 because the wine ti comes with will only execute 64bit windows programs. In order to get around this you must compile the 32 bit version of WINE. The easiest way to do this (in my opinion) is to download the 32bit version of CentOS 7 and throw it on a VM, build wine there, then copy the RPMs and install on your 64bit host.

I was able to accomplish this thanks to the wonderful guide on the  scientific linux forum. In my case I used a virtualbox VM of 32bit Centos7 (you can download the ISO here.) You could also use Docker or even a chroot but virtualbox was the easiest for me to set up.

In the 32bit Centos:

Install necessary packages

Basics

Make sure your system is up to date before you begin your compilation journey.

sudo yum -y update

Install the EPEL repository

sudo yum -y install wget
wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum -y localinstall epel-release-latest-7.noarch.rpm

Install development packages

sudo yum -y groupinstall "Development Tools" 
sudo yum -y install glibc-devel.i686 dbus-devel.i686 freetype-devel.i686 pulseaudio-libs-devel.i686 libX11-devel.i686 mesa-libGLU-devel.i686 libICE-devel.i686 libXext-devel.i686 libXcursor-devel.i686 libXi-devel.i686 libXxf86vm-devel.i686 libXrender-devel.i686 libXinerama-devel.i686 libXcomposite-devel.i686 libXrandr-devel.i686 mesa-libGL-devel.i686 mesa-libOSMesa-devel.i686 libxml2-devel.i686 libxslt-devel.i686 zlib-devel.i686 gnutls-devel.i686 ncurses-devel.i686 sane-backends-devel.i686 libv4l-devel.i686 libgphoto2-devel.i686 libexif-devel.i686 lcms2-devel.i686 gettext-devel.i686 isdn4k-utils-devel.i686 cups-devel.i686 fontconfig-devel.i686 gsm-devel.i686 libjpeg-turbo-devel.i686 pkgconfig.i686 libtiff-devel.i686 unixODBC.i686 openldap-devel.i686 alsa-lib-devel.i686 audiofile-devel.i686 freeglut-devel.i686 giflib-devel.i686 gstreamer-devel.i686 gstreamer-plugins-base-devel.i686 libXmu-devel.i686 libXxf86dga-devel.i686 libieee1284-devel.i686 libpng-devel.i686 librsvg2-devel.i686 libstdc++-devel.i686 libusb-devel.i686 unixODBC-devel.i686 qt-devel.i686 cmake desktop-file-utils fontforge libpcap-devel fontpackages-devel ImageMagick-devel icoutils

Prepare the build environment

Create working directory

mkdir wine && cd wine

Download gcomes’ rpmbuild script

wget 'https://www.centos.org/forums/download/file.php?id=405' -O './rpmrebuild.gz' -c
gunzip ./rpmrebuild.gz ; chmod a+x rpmrebuild

Build chrpath

wget http://vault.centos.org/7.0.1406/os/Source/SPackages/chrpath-0.13-14.el7.src.rpm
./rpmrebuild chrpath-0.13-14.el7.src.rpm

Build openal-soft

wget http://dl.fedoraproject.org/pub/epel/7/SRPMS/o/openal-soft-1.16.0-3.el7.src.rpm
./rpmrebuild -e openal-soft-1.16.0-3.el7.src.rpm

Comment out BuildRequires:portaudio-devel, then save changes (esc:ZZ)

Save and install openal-soft 32-bit rpms (do no skip this step, rpmrebuild erases and restarts each time it is run):

cp rpmbuild/RPMS/i686/openal-soft{,-devel}-1.16.0-3.el7.centos.i686.rpm .

Build nss-mdns

wget http://dl.fedoraproject.org/pub/epel/7/SRPMS/n/nss-mdns-0.10-12.el7.src.rpm
./rpmrebuild nss-mdns-0.10-12.el7.src.rpm
cp rpmbuild/RPMS/i686/nss-mdns-0.10-12.el7.centos.i686.rpm .

Build WINE

With our prerequisites installed we now need to compile 32bit WINE.

wget https://dl.fedoraproject.org/pub/epel/7/SRPMS/w/wine-1.8.4-1.el7.src.rpm
./rpmrebuild -e wine-1.8.4-1.el7.src.rpm
#ZZ to exit, no changes required

Copy RPMs

After the lengthy build process completes be sure to copy the RPMs that were generated. These are the RPMs you will need to copy over to your 64bit Centos 7 for installation.

cp rpmbuild/RPMS/*/* .

In the 64bit CentOS

Install the resulting RPMs by copying them to your 64bit system and using yum localinstall

sudo yum -y localinstall *.rpm

Install winetricks (optional)

wget  https://raw.githubusercontent.com/Winetricks/winetricks/master/src/winetricks
chmod +x winetricks
sudo mv winetricks /usr/local/bin

Success

Now that you’ve made it all the way through the tutorial I will provide a link for the lazy who don’t want to compile their own wine and instead just want to download the RPMs (assuming they want to trust my build). Download the RPMs here.

Fix Xen VGA Passthrough in Linux Mint 17.1

Leave a comment

I wrote in my last post about how I upgraded from Linux Mint 16 to 17.1. I thought everything went smoothly, but it turns out one feature did break: VGA passthrough via Xen. For the past year or so I’ve had a Windows 8.1 gaming VM with direct access to my video card. It’s worked out nicely in Linux Mint 16 but broke completely in 17.1.

I followed the advice of powerhouse on the Linux Mint forums on how to get things up and running, but it wasn’t quite enough. After much banging of my head against the wall I read on the Xen mailing list that there was a regression in VGA passthrough functionality with Xen 4.4.1, which is the version of Xen Mint 17.1 uses.

I finally came to a solution to my problem today – upgrade to Xen 4.5. I couldn’t find any pre-built packages for Ubuntu 14.04 (the base of Mint 17.1) so I ended up compiling Xen 4.5 from source. Below is what I did to make it all work.

Fix broken symlink for /usr/lib/xen-default

sudo rm /usr/lib/xen-default
sudo ln -s /usr/lib/xen-4.4/ /usr/lib/xen-default

Update the DomU CFG file

A couple things needed tweaking. Here is my working cfg:

builder='hvm'
memory = '8192'
name = 'win8.1'
vcpus=6
cpus="2-7"
pae=1
acpi=1
apic=1
vif = [ 'mac=3a:82:47:2a:51:20,bridge=xenbr0,model=virtio' ]
disk = [ 'phy:/dev/mapper/desktop--xen-Win8.1,xvda,w' ]
device_model_version = 'qemu-xen-traditional'
boot='c'
sdl=0
vnc=1
vncpasswd=''
stdvga=0
serial='pty'
tsc_mode=0
viridian=1
usb=1
usbdevice='tablet'
gfx_passthru=0
pci=[ '01:00.0', '01:00.1' , '00:1d.0' ]
localtime=1
pci_power_mgmt=1
on_xend_stop = "shutdown"
xen_platform_pci=1
pci_power_mgmt=1

For some, that’s all they had to do. For me, I had to do a few more things.

Compile Xen 4.5

This step was thanks to two different sites, this one and this one.

Install necessary packages

sudo apt-get install build-essential bcc bin86 gawk bridge-utils iproute libcurl3 libcurl4-openssl-dev bzip2 module-init-tools transfig tgif texinfo texlive-latex-base texlive-latex-recommended texlive-fonts-extra texlive-fonts-recommended pciutils-dev mercurial libjpeg-dev make gcc libc6-dev-i386 zlib1g-dev python python-dev python-twisted libncurses5-dev patch libvncserver-dev libsdl-dev libpixman-1-dev iasl libbz2-dev e2fslibs-dev git-core uuid-dev ocaml ocaml-findlib libx11-dev bison flex xz-utils libyajl-dev gettext markdown libaio-dev pandoc

Checkout Xen source

git clone git://xenbits.xen.org/xen.git xen-4.5.0
cd xen-4.5.0
git checkout RELEASE-4.5.0

Build from source

./configure --libdir=/usr/lib
 make world -j8

When I tried this the make failed with this error:

/usr/include/linux/errno.h:1:23: fatal error: asm/errno.h: No such file or directory
 #include <asm/errno.h>

The fix (thanks to askubuntu)  was to install linux-libc-dev and make a symlink for it:

sudo apt-get install linux-libc-dev
sudo ln -s /usr/include/asm-generic /usr/include/asm

It then compiled successfully.

Install freshly compiled Xen 4.5

sudo make install
sudo update-rc.d xencommons defaults
sudo update-rc.d xendomains defaults
sudo ldconifg

Set grub to boot from new Xen kernel

sudo update-grub
sudo vim /etc/default/grub

Edit GRUB_DEFAULT to match wherever update-grub put your new Xen kernel (in my case it was the second entry, so my GRUB_DEFAULT=1), then run update-grub again

sudo update-grub

Reboot

Success at last. Enjoy your VM gaming once more with Xen 4.5.

Convert xenserver .xva file to raw disk image

5 Comments

What if you want to migrate a VM that’s been living on Citrix Xenserver to a different linux machine running vanilla Xen? The process isn’t as straightforward as you might think. Fortunately thanks to Eriklax over at github there is a fairly easy way to convert xenserver’s .xva virtual machines to other formats, via xva-img.

The first step is to download and install xva-img from github.

wget https://github.com/eriklax/xva-img/archive/master.zip
unzip master.zip
cd xva-img-master
cmake .
sudo make install

When trying to compile this on my Linux Mint Cinnamon machine I ran into the following errors:

CMake Error: your CXX compiler: "/usr/bin/c++" was not found.   Please set CMAKE_CXX_COMPILER to a valid compiler path or name.
xva-img-master/src/sha1.cpp:20:25: fatal error: openssl/sha.h: No such file or directory
 #include <openssl/sha.h>

I had to install the build-essential and libssl-dev packages in order to successfully compile and install xva-img.

Now that it’s installed, create a directory and extract your .xva file into it.

mkdir my-virtual-machine 
tar -xf <.xva file> -C my-virtual-machine 
chmod -R 755 my-virtual-machine

Once that’s finished (it might take a while – it took over an hour for me) the last step is to convert the extracted directories into a raw disk file.

Note:  when you extract your VM tar creates subfolders for each hard disk attached to the VM. You will have to run this command for each Ref folder that was generated as part of the image extraction process.

xva-img -p disk-export my-virtual-machine/Ref\:1/ disk.raw

It took a while for some reason, but it did eventually generate the desired image.

Now that I have a raw disk image I can transfer it to an LVM partition for use with xen:

sudo dd if=win8.1.img of=/dev/desktop-xen/Win8.1 bs=64M

Success.
