RealXtend Viewer Linux

Overview

It's already possible to testrun modrex on linux/macos, so a crossplatform solution for the viewer is needed as well. Most libraries used in the RealXtend viewer are cross-platform. Nevertheless there are some windows dependencies, which prevents the viewer to compile and run on the Linux/OSX platform. In the meanwhile we can use the viewer through the use of wine. Wine allows to run native win32 applications on Linux, and on OSX using the Darwine modifications. Wine is not an emulator, and is faster than one might expect. RealXtend runs quite stable on wine(40/50 fps) with archlinux i686 distro, nvidia 8600GT, Athlon 3200+ and 2GB ram.

RealXtend on Linux

Linux Procedure

• install git
• Get the latest wine

git clone git://source.winehq.org/git/wine.git ~/wine-git
cd ~/wine-git

• get the wglShareLists patch and copy into ~/wine-git/dlls/winex11.drv
• Do the patch for opengl.c

patch -p0 < attachment.patch

• Build wine(not as root)

~/wine-git/tools/wineinstall

• Add libraries(dx9, .net, etc.) using winetricks
• try to run the viewer

wine ~/.wine/drive_c/Program\ files/RealXtend/realXtend.exe

• Tweak wine in case the viewer crashes.

winecfg

There are some libraries which can be tweaked, in case the viewer crashes on load. My settings are: rpcrt4(buildin native), comctl32(native buildin)

Mac OSX Procedure

• Install fink. Notice that realXtend won't work on PowerPC based MAC's
• Install finkcommander
• Start finkcommander, install cvs, wget, gcc4, make
• Add the fink binaries to your path config. Open a terminal

vi /Users/myuser/.profile
//add this line
export PATH=/sw/bin:$PATH

• Check out the Darwine code, and wine from the terminal, and unpack wine

mkdir /Users/myuser/wine
cd /Users/myuser/wine
cvs -z3 -d:pserver:anonymous:@darwine.cvs.sourceforge.net:/cvsroot/darwine co -P distrib
wget http://ovh.dl.sourceforge.net/sourceforge/wine/wine-1.1.21.tar.bz2
tar -xjvf wine-1.1.21.tar.bz2

• Launch the darwine script

cd distrib
export VERSION=1.1.21
./create_darwine_distrib.sh $VERSION /Users/myuser/wine/wine-1.1.21
find /sw/fink/dists -name wine.info

Known Quirks

• If the viewer refuses to start(complaining about window creation) after some succesful sessions, then remove ~/.wine/drive_c/windows/profiles/user/Application\ Data/realXtend
• After a normal quit, the colors of the desktop may become hippy-like distorted. Kill the proces instead to avoid it.(killall -15 realxtend.exe)
• The Skype part doesn't work with skype for linux. Didn't manage to test skype with wine(that may work)
• VNC on a prim doesn't work properly...

Have fun!
