TeXLive 2018 update

Today I updated my TeXLive install to 2018. Although the install went fine, there was a problem with the binaries.

Both asymptote and xetex were linked to different versions of some libraries than those that are supplied by ports. So I had to rebuild them.

Reason

Some might wonder why I install TeXLive myself instead of using the one from ports. The reasons for doing that are nicely summed up at anthesphoria.net.

Personally I think that it is a bit of a waste of time to re-package TeXLive for ports, since TeXLive basically lives in its own tree and is built to use as little system libraries as possible.

There is only one port that I use which is influenced by my using TeXLive: gnuplot. Therefore I always build a private version of that port.

Preparations

I changed the ownership of /usr/local/texlive to myself, so I could install and upgrade as a normal user. Next I made a backup of my current installation, just to be sure.

# chown -R rsmith:rsmith /usr/local/texlive
> cd /usr/local/texlive
> tar cvf ~/backup-texlive-2017.tar 2017/

Installation

After downloading the network installer from here, I unpacked it and ran it as rsmith, after setting the umask. (my default umask shuts out other users.) It found my previous install in /usr/local/texlive/2017 and offered to use the settings I had employed then.

This installed 3541 packages. After the installation, I removed the 2017 tree.

> cd /usr/local/texlive
> rm -rf 2017/

Adjusting the configuration

The path to several parts of the TeXLive distribution are found in several places in my configuration files:

  • csh.cshrc
  • config.asy
  • cshrc.root
  • login.conf
  • profile
  • texlive.conf

Fortunately, I keep all these files in a separate directory tree (which is also a git repository), so updating all these path was relatively simple using find with sed.

cd setup/
find . -type f -not -path './.git/*' -not -name './*.jpg' \
-exec sed -i '' -e 's|texlive/2017|texlive/2018|g' {} \;

After checking in these changes, I used my deploy script to roll them out.

Since the PATH environment variable is set in login.conf, I needed to log out and back in to effect the changes.

Fonts

All the opentype fonts in my TeXLive installation are linked to one of my global font directories, so other programs can find them. This is accomplished by the shell-script tex-fonts.

This needs to be run after every TeXLive install and removal of the old texlive version.

> cd ~/src/scripts/public
# sh texfonts.sh

Rebuilding programs with incorrect libraries

Looking at the output of ldd /usr/local/texlive/2018/bin/amd64-freebsd/*, it seems that some libraries are not correct:

  • asy is missing libOSMesa.so.9 (FreeBSD ports provide libOSMesa.so.8), libglut.so.12 (FreeBSD ports provide libglut.so.3) and libreadline.so.8 (FreeBSD ports provide libreadline.so.7).
  • xetex is missing libfreetype.so.9 (FreeBSD ports provides libfreetype.so.6, which xetex is also linked to).

I’m not sure where these mismatches come from.

Rebuilding asymptote

According to /usr/local/texlive/2018/texmf-dist/asymptote/version.asy, texlive needs asymptote 2.44. I’ve downloaded asymptote-2.44.src.tgz and asymptote.pdf from sourceforge, unpacked the tarball and built it.

Building asymptote with OpenGL and off-screen rendering support was done as follows. Note that the configure.ac file needs a small patch, because libOSMesa requires libunwind.

This yields a working asymptote.

Rebuilding XeTeX

To rebuild this, I downloaded texlive-20180414-source.tar.xz from ftp://tug.org/texlive/historic/2018/

> cd ~/tmp/src/
> mkdir xetex-build
> tar xf ../texlive-20180414-source.tar.xz
> cd xetex-build/
> env MAKE=gmake ../texlive-20180414-source/configure --disable-all-pkgs \
--enable-xetex --disable-debug --with-system-libpng -C \
--with-system-poppler --with-system-freetype2
> gmake
> cd texk/kpathsea/
> gmake
> cd ../web2c
> gmake xetex
> mv /usr/local/texlive/2018/bin/amd64-freebsd/xetex \
/usr/local/texlive/2018/bin/amd64-freebsd/xetex.orig
> chmod a-x /usr/local/texlive/2018/bin/amd64-freebsd/xetex.orig
> install -s xetex /usr/local/texlive/2018/bin/amd64-freebsd/
> cd ..
> rm -rf xetex-build/
> rm -rf texlive-20180414-source/

This yields a working xetex. It does use a lot more system libraries than the original one but I can live with that. So I have not expended any effort to minimize the amount of libraries used.
