Paul (and rooters),
I've had similar problems on Linux. However, I was using ROOT 2.22v09.
I had problems with many different classes besides TPaveLabel. I had
assumed that the documentation on the web had been updated, and that I
was using an older version that did not implement certain functions. I
find it interesting that you have a similar problem with another
version...
I also had type casting problems when calling functions, i.e. I would
try to pass a character string (char *) to a function with a Text_t *
parameter, and had funny messages saying that there was no function with
an equivalent signature. I assume this was part of the same problem...
Fons, Rene?
Regards,
Dan.
