Hi Andrej,
did you run your commands on linux or on Windows?
I installed WinGraphviz this morning and I found that the Windows version is nothing but
WinGraphviz.dll which is registered then. I am new to this, but as far as I understand, I can
use this dll by creating an object, e.g. WinGraphviz.dot in some piece of cpp, vbs
(successfully tested) or perl code. There is no system32 command named dot, so I fear,
your code in draw_graph.mac
command : concat("dot -Tplain \"", gp_file_in, "\" > \"", gp_file_out, "\"")
...
system(command),
doesn't work on Windows. What can I do?
