Original report by Jorge Araya Navarro (Bitbucket: [Jorge Araya Navarro](https://bitbucket.org/Jorge Araya Navarro), ).

I compiled ryzom, just the client, but when I try to run ryzom_client it just crashes. Here is some debug that I did using GDB:

#!/usr/bin/env bash

My CMake options were:

#!bash

cmake -Wno-dev "source/code" -DWITH_SYMBOLS=ON -DWITH_STATIC=OFF -DWITH_NEL_TOOLS=OFF -DWITH_NEL_TESTS=OFF -DWITH_LUA51=ON -DWITH_NEL_SAMPLES=OFF -DWITH_RYZOM_TOOLS=OFF -DWITH_RYZOM_SERVER=OFF -DWITH_RYZOM_CLIENT=ON -DWITH_NEL=ON -DWITH_DRIVER_OPENGL=ON -DWITH_DRIVER_OPENAL=ON -DCMAKE_INSTALL_PREFIX=/usr -DRYZOM_ETC_PREFIX=/etc/ryzom -DRYZOM_SHARE_PREFIX=/usr/share/ryzom -DRYZOM_BIN_PREFIX=/usr/bin -DRYZOM_GAMES_PREFIX=/usr/bin

We do a source code snapshot when packaging software from distributed version control like mercurial or git and so, so here is the source code snapshot used to build Ryzom.

The dependencies and build dependencies were these: 

#!bash
depends=('curl' 'hicolor-icon-theme' 'libvorbis' 'libjpeg' 'libwww' 'luabind') # 'freetype2' 'libx11' 'mesa' 'libxxf86vm' 'openal' 'libogg' 'libxml2' 'libpng' 'lua51' are dependencies already included by other dependencies in the array according to namcap.
#!bash
makedepends=('mercurial' 'cpptest' 'cmake' 'bison' 'freealut' 'rrdtool' 'boost')

We already had this problem in the past, libxmlparse.so.0 is from libwww and your OpenGL driver is linked to libexpat that define the same symbols. You have to recompile libwww to use external expat library, the same as your OpenGL driver or to compile libwww in full static.

I have some issues compiling libwww. Is There any other workaround?

Original comment by Cédric Ochs (Bitbucket: [Cédric OCHS](https://bitbucket.org/Cédric OCHS), ).

Did you use ./configure and make ?

of course I did!!

But libwww is a package already provided in our repositories, thus, I tried to built a static version of it using the sources from the W3, but it seems to have some issues with newer versions of gcc.

I just changed the source code with the yours, and everything went well :). The next step is to build ryzom using that libwww built.

EDIT: Something went wrong while building Ryzom and seems related to your libwww:

I compiled and packaged your libwww version with these options:

./autogen.sh
./configure --prefix=/usr/local \
    --with-ssl=no --with-zlib --with-expat --with-gnu-ld \
    --enable-shared=no --enable-static
  make

May I did something wrong?

fixed, libwww fork of @kervala does magic :D

But, I'll appreciate a better way of packaging Ryzom that does use the already provided software and libs :)
