I have realized the cause of the problem. To enable pdf creation on the fly, the `\write18' has to be enabled via the command line option: -shell-escape of pdflatex (example: pdflatex -shell-escape test.tex) or via the configuration file `texmf.cnf': (shell_escape = 1) as it is stated in the epstopdf.sty file. However one should not expect the user to dig into the sty files.
Therefor I suggest an appropriate error message, when the epstopdf packages is used in latex documents, but `\write18' is disabled. In addition an example of how to enable it (example: pdflatex -shell-escape test.tex) would be very helpful.
