Hello all.
I solved this problem by adding "...\bin" to the PROJECT variable in systel.ini. I'm not sure why this works, but at least the compilation is running. The new output in the command window is
Repertoire ´special/special/v6p1.......´ inexistant
Repertoire ´damocles/damo_v6p1 ........´ inexistant
...
(and so on for all base directories)
I read in the FAQ section that this is not really an error, and that the compliation DID take place. Anyway, I removed "...\bin" from PROJECT in systel.ini after this and the model seems to run adequately.
Saludos
