General

This page applies for Debian-based GNU/Linux distributions. It should work on other linux distribution too, but some package name might change. To compile Ryzom client under Mac OS X, please check this page : Building Ryzom Client under Mac OS X


If you build the client for your own system, i recommend building a dynamically linked version ; you can follow Building_Ryzom_Client_On_Debian_(Stripped_Version) to do this (the steps are also included in this guide but there is no risk of confusion using the stripped version). If you want to distribute some binaries (and only if you want to do that), you should build a static version. It's highly recommended to build with an old libc version. The easiest version to do that is using an old distribution ; here i use a chroot because i want to have a clean build environment, but you can perfectly do it in your own system, just skip the #Setting up the chroot part, and command run as user inside the chroot as simple user [in your system], command run as root inside the root as root [in your system] :)

Why should i build my own client ?

There is a couple of valables reasons :

Setting up the chroot

The host system should be a debian or any derivate. Didn't tested but if you chroot a squeeze, your debian version should be at least a squeeze too. I choosed squeeze because the libc version is pretty old, so the static binary compiled should work on (almost) every linux system. 

$ command means run as simple user
# command means run as root
#$ command means run as simple user inside chroot
## command means run as root inside chroot

Don't forget to change USER by your username or it won't work :p 

# apt-get install debootstrap dchroot
$ mkdir -p /home/USER/chroot/ryzom_squeeze64
$ mkdir -p /home/USER/chroot/ryzom_squeeze32
# debootstrap --arch amd64 squeeze /home/USER/chroot/ryzom_squeeze64 http://ftp.fr.debian.org/debian
# debootstrap --arch i386 squeeze /home/USER/chroot/ryzom_squeeze32 http://ftp.fr.debian.org/debian

!!The instruction are only for the 64 bits chroot, just change the path for the 32 bits one :) 

# chroot /home/USER/chroot/ryzom_squeeze64
## apt-get install wget nano locales dialog apt-utils
## dpkg-reconfigure locales
## nano /etc/apt/sources.list

It should look like this : 

deb http://ftp.fr.debian.org/debian squeeze main contrib non-free
deb-src http://ftp.fr.debian.org/debian squeeze main contrib non-free

## apt-get update
## exit
# cp /etc/passwd/ /home/USER/chroot/ryzom_squeeze64/etc/
# sed 's/\([^:]*\):[^:]*:/\1:*:/' /etc/shadow | tee /home/USER/chroot/ryzom_squeeze64/etc/shadow
# cp /etc/group /home/USER/chroot/ryzom_squeeze64/etc/
# cp /etc/hosts /home/USER/chroot/ryzom_squeeze64/etc/
# chroot /home/USER/chroot/ryzom_squeeze64
## passwd

I recommend using the same password as the root on your system (i think the root's password is supposed to be copied, not sure why it don't work) 

## exit

Now we have to mount some directory for our chroot : 

# nano /etc/fstab

Add the following lines : 

/proc /home/USER/chroot/ryzom_squeeze64/proc none rbind 0 0
/dev /home/USER/chroot/ryzom_squeeze64/proc none rbind 0 0
/sys /home/USER/chroot/ryzom_squeeze64/proc none rbind 0 0
/tmp /home/USER/chroot/ryzom_squeeze64/proc none rbind 0 0

# mount -a
# chroot /home/USER/chroot/ryzom_squeeze64
## echo ryzomm_squeeze64 >> /etc/debian_chroot
## exit
# nano /etc/schroot/schroot.conf

Add the following lines (make sure to change the "users=" line & directory line) 

[ryzom_squeeze64]
description=Squeeze 64bits for ryzom
directory=/home/USER/chroot/ryzom_squeeze64
users=USER
groups=sbuild
root-groups=root

[ryzom_squeeze32]
description=Squeeze 32 bits for ryzom
directory=/home/USER/chroot/ryzom_squeeze32
users=USER
groups=sbuild
root-groups=root
personality=linux32

You can now use your chroot as a normal user, just type : 

$ dchroot -c ryzom_squeeze64

You won't have a ~ the first time you log in, just create it 

#$ su -
## mkdir /home/USER
## chown USER:USER /home/USER
## exit

Congratulations ! Your chroot are now working perfectly !

Downloading ryzom dependencies

Tools needed to build the client : 

## apt-get install mercurial  autoconf automake cmake libtool build-essential bison

Libraries needed : 

## apt-get install libluabind-dev libfreetype6-dev libcurl4-openssl-dev libx11-dev \
libgl1-mesa-dev libxxf86vm-dev libxrandr-dev libxrender-dev libopenal-dev \
libogg-dev libvorbis-dev libxml2-dev libpng12-dev libjpeg-dev libxmu-dev

Compiling ryzom dependencies

If you do a regular build of the client on Debian, you won't need this. If you want to build some of the tools and/or you couldn't install some of the packages, kervala created a repo with all the dependencies needed for ryzom.

First, download all the code you need : 

#$ cd ~
#$ mkdir dep_ryzomcore && cd dep_ryzomcore
#$ hg clone http://hg.kervala.net/packaging
#$ hg clone http://hg.kervala.net/cmake

The compilation method will slightly depends, but it will probably look like one of those two examples (who are used to build the tools, not the client itself) : libsquish : 

#$ cd ~/dep_ryzomcore/
#$ export CMAKE_MODULE_PATH=$(pwd)/cmake/modules
#$ cd packaging/squish
#$ mkdir build && cd build
#$ cmake ..
#$ make
## make install

cpptest : 

#$ cd ~/dep_ryzomcore/packaging/cpptest/
#$ sh ./autogen.sh
#$ ./configure
#$ make
## make install

Note : If you have trouble during the autogen.sh / configure part due to glibtoolize, find the following line (should be line 31) : 

if glibtoolize --version &>/dev/null ; then

and replace it by : 

if hash glibtoolize 2>/dev/null ; then

Compiling ryzom dependencies, static version specific

We need to build libopenal static : 

#$ cd ~
#$ mkdir libopenal && cd libopenal
#$ apt-get source libopenal1
#$ nano openal-soft-1.12.854-2/debian/rules

add this line "-DLIBTYPE=STATIC", after line 15, so you'll something like this : 

               -DALSOFT_CONFIG=ON \
               -DLIBTYPE=STATIC \



## apt-get build-dep libopenal1
#$ cd openal-soft-1.12.854-2
#$ dpkg-buildpackage -rfakeroot -uc -b

Unfortunately the install isn't going well so we need to copy the static lib by hand : 

##cp ~/libopenal/openal-soft-1.12.854-2/build-tree/libopenal.a /usr/lib

And now we need a static curl : 

#$ cd ~
#$ mkdir libcurl && cd libcurl

I prefer to have the same curl version as my system (check apt-cache policy libcurl3 to have the info) but it shouldn't change much 

#$ wget -c http://curl.haxx.se/download/curl-7.21.0.tar.bz2
#$ tar xjf curl-7.21.0.tar.bz2
#$ cd curl-7.21.0
#$ ./configure --disable-ldap --disable-ldaps --disable-rtsp --disable-dict --disable-ipv6 \
--disable-crypto-auth --disable-sspi --disable-tls-srp --without-gnutls --without-librtmp \
--without-libidn --disable-versioned-symbols --disable-pop3 --without-libssh2
#$ make
## make install

Getting ryzom code

#$ cd ~
#$ hg clone https://bitbucket.org/ryzom/ryzomcore

We just need to switch branch (default to compatibility-develop) 

#$ cd ryzomcore
#$ hg update -c compatibility-develop

If you need to update the code later, just type : 

#$ hg pull && hg update

Building Ryzom (static version)

#$ cd ~
#$ mkdir build_static && cd build_static

use the following cmake options : 


#$ cmake -DWITH_NEL_TESTS=OFF -DWITH_NEL_SAMPLES=OFF -DWITH_NEL_TOOLS=OFF -DWITH_RYZOM_CLIENT=ON \
-DWITH_RYZOM_SERVER=OFF -DWITH_RYZOM_TOOLS=OFF -DWITH_NEL=ON -DWITH_SOUND=ON -DWITH_DRIVER_OPENGL=ON \
-DWITH_DRIVER_OPENAL=ON -DWITH_STATIC=ON -DWITH_STATIC_DRIVERS=ON -DWITH_NEL_TESTS=OFF \
-DWITH_LIBWWW_STATIC=ON -DOPENAL_LIBRARY=/usr/lib/libopenal.a -DOPENGL_gl_LIBRARY=/usr/lib/libGL.so \
-DWITH_STATIC_EXTERNAL=ON -DWITH_STLPORT=OFF -DCURL_LIBRARY=/usr/local/lib/libcurl.a ../ryzomcore/code

The directory of libGL.so might change, depending on the strange things happenin in /usr/lib with the i386/ amd64 directory, check it before building.

Here, n is the number of core in your CPU : 

#$ make -jn

Building Ryzom (dynamically linked)

#$ cd ~
#$ mkdir build && cd build

For differents cmake options, see #CMake options. Here's the one i'm using : 

#$ cmake -DWITH_NEL_TESTS=OFF -DWITH_NEL_SAMPLES=OFF -DWITH_NEL_TOOLS=OFF -DWITH_RYZOM_SERVER=OFF \
-DWITH_RYZOM_TOOLS=OFF -DWITH_QT=OFF -DWITH_RYZOM_CLIENT=ON ../ryzomcore/code

If you are having trouble with cmake who can't find LIBWWW_INCLUDE_DIR, it's probably because the make install of libwww put everything in a subfolder of /usr/local/include and cmake doesn't seems to find it. Easiest way to solve it is : (the path may change a little on your computer) 

## cd /usr/local/include/-package/
## mv * ..

Then run cmake again Here, n is the number of core in your CPU : 

#$ make -jn

The binary is now in bin/ryzom_client. You can't really use this one like that, because you need all the libs (libnel* + libryzom* that you just compiled, libwwwthat you compiled earlier). If you want to use this one, copy all the file in lib/ and all the file in /usr/local/lib in your system (/usr/local/lib for example). Easy (and clean) way to do that is to run the following command : 

## make install

Will put all the needed file where they belong :) (ryzom_client will go to /usr/local/games)

How do i use my client ?

Very simple ! Just copy your ryzom_client executable (from your bin/ folder if it's static, or /usr/local/games if you built it dynamic way) to your ryzom folder. I recommend keeping the official ryzom_client and renaming yours, so you have a backup client in case of trouble !

Adding debugging symbols (useful if you want to run gdb) : 

#$ cmake -DWITH_SYMBOLS=ON ALLOTHEROPTIONS ..

Debug mode (useful only if you are a dev ; it's a bad idea to use it if you aren't cause there is more crash + it's slower) : 

#$ cmake -DFINAL_VERSION=OFF -DCMAKE_BUILD_TYPE=Debug ALLOTHEROPTIONS ..

Auto-build script

A simple script to build different (static) version of the client : [1]

Another script to manage the built ryzom_client : launch a new build (both 64 & 32 bits) using my chroot, then saving everything and uploading it to my server : [2]
