# tikz cd: ! I can't find file librarycd.code.tex'

The cd package for tikz seems to be failing, or missing. I am using Kile in Ubuntu 10.4, and I installed all the tikz-related packages my package manager could find.

MWE:

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{cd}

\begin{document}

bla

\end{document}

• @Gale Which version of TikZ are you using? Would the package tikz-cd be feasible for you? Apr 10 '15 at 7:21
• @Gale does your error persist? Have you been able to update your version of TikZ? Apr 29 '15 at 13:30

You need to install the tikz-cd package. It is not directly part of TikZ. Possibly not even part of your Linux package manager. You could get it from CTAN then.
Then, load the tikz-cd package:
\usepackage{tikz-cd}

\usepackage{tikz}
