Due to Alan, Julien and others I finally got the installation of LyX 2 done. Thanks.
I was using Debian sid under Linux. There were several hurdles (at least for me) I had to jump over. ###Texlive#### For the installation of texlive I used the description of Rolf Nipraschk (Dante 2/2009 pg 57ff) and the DVD "TeX Collection" 2009 which contains the TexLive distribution. It boils down to cd /media/TeXCol2009/texlive (or adjust path) ./install-tl D 2 instead of the shown default path /usr/local/texlive/texmf-local enter /usr/local/share/texmf R (back to start menu) I (begin of installation) Alternatively one can install texlive via the internet cd /tmp wget http://mirror.ctan.org/systems/texlive/tlnet/2009/install-tl-unx.tar.gz and start the installation prg: cd install-tl ./install.tl can take 1-2 hours; if net connection broken, automatic continuation after a new trial remove install programms: cd .. rm -r install-tl-unx.tar.gz install-tl Setting the pathes after installation: create new file /etc/profile.d/zzz-texlive.sh (or, as I did, since debian has /etc/profile only, I added the following lines to the end of the profile file) with the following lines: #for Texlive export PATH=/usr/local/texlive/2009/bin/i386-linux:$PATH export MANPATH=/usr/local/texlive/2009/texmf/doc/man:$MANPATH export INFOPATH=/usr/local/texlive/2009/texmf/doc/info:$INFOPATH unset TEXINPUTS unset TEXMFCONFIG (the last two lines ensure the use of the texlive pathes and not the one of an old tex installation) where i386-linux:$PATH in the first line was according to the proposal of Nipraschk export PATH=/usr/local/texlive/2009/bin/´uname -i´-linux:$PATH or, as he corrected in the next edition of Dante: export PATH=/usr/local/texlive/2009/bin/$´uname -m | sed -e ´s/i.86/i386/)-linux:$PATH briefly: you have to tell for the path the Linux/unix variant you are using As an alternative, the pathes can be given also in a local ~/.profile or ~/.bashrc file, e.g. if you have no root access In this way the OS system finds the newly installed prgs I did furthermore a texhash as user and as root. Not sure its necessary. You can test after restarting your Linux system by which tex should give /usr/local/texlive/2009/bin/x86-64-linux/tex and kpsewhich article.cls should give /usr/local/texlive/2009/texmf-dist/tex/latex/base/article.cls might be worth to wait for the new texlive 2010 or update to it via (as root) tlmgr option location http:/mirror.ctan.org/systems/texlive/tlnet/2010 tlmgr update bin-texlive texlive.infra tlmgr update --all with getnonfreefonts-sys --all (as root) one gets fonts which are not part of the texlive ###lyx20### I used the instructions of Julien Rioux (Mail this list of 05.07.2010), but with stow. My debian (I used a minimal version for installing it) did not contain some prgs needed such as qt4 and qt4-devel and some libs. This turned up during the steps. build-dep is in build-essentials in the debian synaptic manager stow automake autoconf autogen The steps: (root or user) 1 - svn co svn://svn.lyx.org/lyx/lyx-devel/branches/TRUNK lyx20 2- cd lyx20 3- ./autogen.sh 4- ./configure --with-version-suffix=20 --enable-build-type=release 5- make (takes quite some time) 6- (as root or sudo) make install prefix=/usr/local/stow/lyx20 ###sudo### I did not have sudo installed. One has to use visudo (as root) to edit the file sudowers and add at the end for not needing the password wolfgang ALL=NOPASSWD: ALL where wolfgang is the user I have, however, used root so far, not sudo Thanks again who helped me.
