Indico uses LaTeX (xelatex to be exact) to generate some PDF files such as the Book of Abstracts and the PDF versions of contributions.
Since Indico requires quite a few LaTeX packages which are not always] installed by default when using the texlive packages of the various linux distributions, we recommend installing it manually.
First of all, you will need to install some dependencies so that all TeX formats are generated successfully upon TeXLive installation.
yum install fontconfig ghostscript # CentOS / CC7 apt install libfontconfig1 ghostscript # Debian / Ubuntu
You are now ready to install TeXLive. The following commands should work
fine to install everything you need.
You need to run the installation as root or create
root and grant your user write access to it.
Download the installer and cd to its location (the directory name contains the date when the package was built, so use the wildcard or type the name manually based on the output when unpacking the archive):
cd /tmp wget http://mirror.ctan.org/systems/texlive/tlnet/install-tl-unx.tar.gz tar xvzf install-tl-unx.tar.gz cd install-tl-*/
Create the setup config file to install all the packages you need:
cat > texlive.profile <<'EOF' selected_scheme scheme-full TEXDIR /opt/texlive TEXMFCONFIG ~/.texlive/texmf-config TEXMFHOME ~/texmf TEXMFLOCAL /opt/texlive/texmf-local TEXMFSYSCONFIG /opt/texlive/texmf-config TEXMFSYSVAR /opt/texlive/texmf-var TEXMFVAR ~/.texlive/texmf-var binary_x86_64-linux 1 instopt_adjustpath 0 instopt_adjustrepo 0 instopt_letter 0 instopt_portable 0 instopt_write18_restricted 1 tlpdbopt_autobackup 1 tlpdbopt_backupdir tlpkg/backups tlpdbopt_create_formats 1 tlpdbopt_generate_updmap 0 tlpdbopt_install_docfiles 0 tlpdbopt_install_srcfiles 0 tlpdbopt_post_code 1 tlpdbopt_sys_bin /usr/local/bin tlpdbopt_sys_info /usr/local/share/info tlpdbopt_sys_man /usr/local/share/man EOF
Start the installer and wait for it to complete. This may take between a few minutes and a few hours depending on the speed of the (randomly chosen) mirror.
./install-tl --profile texlive.profile
After installing it, add this line to your
indico.conf file to use
your new TeXLive installation:
XELATEX_PATH = '/opt/texlive/bin/x86_64-linux/xelatex'
If you are in a production setup, reload uWSGI using
touch /opt/indico/web/indico.wsgi to reload the config file.
As security-related updates are released frequently, it is also a good idea to periodically update the TeXLive packages by running:
/opt/texlive/bin/x86_64-linux/tlmgr update --self --all
