I've recently started using LaTeX for all my documentation and can't believe I didn't do this sooner! It's so quick to get good-quality documentation produced, and the LaTeX format serves brilliantly as an interim format for conversion to others. I'm having a lot of fun :D

What I want to do presently is write a sequence diagram for a software build process. I'm using Tex Live 2011 and pdflatex (same result using plain old latex) in Cygwin on Windows XP to process my .tex file:


\usepgflibrary{arrows} % for pgf-umlsd





As you can see, it's very simple.

When I run this through latex/pdflatex I get:

) (./build-process.aux) ABD: EveryShipout initializing macros

! Package pgf Error: No shape named inst1 is known.

See the pgf package documentation for explanation.
Type  H <return>  for immediate help.

l.12   \end{sequencediagram}


What am I doing wrong? Furthermore, will my platform and software suffice to allow me to write sequence diagrams in LaTeX?

Thanks in advance!

Does swapping around the \uspackage{pgf-umlsd} and the \usetikzlibray{arrows} help? – Seamus Aug 3 '11 at 10:51
No, I placed \usetikzlibrary{arrows} before \usepackage{pgf-umlsd} and it didn't help. – atc Aug 3 '11 at 11:01

I think you're using a somewhat old version from pgf-umlsd.sty which does not support empty diagrams. Version 0.6 should fix this (and does that in my case) and TeX Live 2011 uses 0.5 as far as I could see.

You could download it from: http://code.google.com/p/pgf-umlsd

This fixed it! Thanks! I manually copied the .sty in the .zip from your link to /texlive/2011/texmf-dist/tex/latex/pgf-umlsd/, after backing it up. – atc Aug 3 '11 at 11:31
