I am using Tex Live 2015, and I am trying to produce a glossary using the glossaries package. The style that I am trying to use is
alttree. In order to use this you need to define the width of the longest glossary entry, however I have seen that in a recent update a command has been defined to automatically find the widest element:
\glsfindwidesttoplevelname. Unfortunately despite having updated all packages in TeX Live, I still obtain the following error:
! Undefined control sequence.
When looking in the install location of the glossaries style file, it appears that my
glossary-tree.sty file was last updated in January this year. How does one update this style file?
