Hi Kasra,
I debugged into the problem and found that
\tikzexternalcheckshellescape
does NOT expand to '-shell-escape'.
It smells like a bug in the external library... I will take care of it.
The purpose of the \tikzexternalcheckshellescape macro was to expand to
the shell-escape argument if and only if it was present on the command
line. To this end, it relies on some pdftex macro - which appears to be
undefined for lualatex.
The immediate solution would be to use '-shell-escape' instead of
'\tikzexternalcheckshellescape', i.e.
\tikzset{external/system call={lualatex -shell-escape -halt-on-error
-interaction=batchmode -jobname "\image" "\texsource"}}
In that case, the argument 'external/shell escape' is ignored (it is
only used by \tikzexternalcheckshellescape).
Kind regards
Christian
