SigmaPi Embedded compilation problem
If you compile SigmaPi using QT/Embedded, you will
have to include the -fno-rtti flag.
Also, use -DQWS and remove the X11/Xext libraries
as well as the path to the X11 directory.
Furthermore, the library is called qte-mt now.
Don't forget to use ./configure -thread when
configuring QT. is not enough, you need

SigmaPi compilation problem
Some people seem have problems compiling SigmaPi.
Please note that QT has to be configured using
./configure -thread
to enable multithreading. After QT has bee built,
read the README file to generate the Makefile.
Don't forget to enable multithreading with
-DQT_THREAD_SUPPORT and to link agains -lqt-mt
If you don't do this, you'll get an error from
the NN_trainer file

SigmaPi 0.7 & 0.8 bug
Hi there,,
I found a bug in SigmaPi Version 0.7 and 0.8.
It causes patterns to get an ID of 0, so that they are stored
and also trained, but after the pattern contoller has been
changed, they are invisible to the user (at least on a PPC).
This bug is in SigmaPi 0.7 and 0.8 (the .zip versions), and has
been removed today.
So if you experience this problems, download 0.7 and 0.8
again on
