I'm trying to buld the example called Elliptic Curve Group Operations from the TikZ for Cryptographers website. I have PGF 3.0.1, installed in my home dir under
But I'm not able to compile the example. I'm running
pdflatex --shell-escape ec-rules.tex
Unfortunately I get the error:
Package pgf Error: No shape named intersection-1 is known
I have no clue, what's the issue (since I never worked with intersections).
