As some of you may have noticed, SigmaPi does not compile
The problem has already been solved, the next release will
work with all GCC compilers. If you need a pre-release version,
mail me an I will send you 1.2alpha
I've added a manual for SigmaPi.
It can be downloaded from the SigmaPi Homepage.
Linux/Sparc Solaris/Sparc and FreeBSD/x86 ports added
I've just added SigmaPi 1.0 ports to Sparc Linux
and Solaris and to FreeBSD/x86.
The binaries are not tested.
Linking on FreeBSD
On FreeBSD, there is non pthread library.
The POSIX threads live in libc_r.so.
To port SigmaPi to FreeBSD, add -lc_r to the
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
libqte.so is not enough, you need libqte-mt.so
SigmaPi compilation problem
Some people seem have problems compiling SigmaPi.
Please note that QT has to be configured using
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 for Linux on Sparc
I've compiled SigmaPi 0.9 on a SparcStation using
Debian Linux 2.2.
The binaries are downloadable on the Homepage.
SigmaPi on Solaris 8
I've just included a statically linked binary
for Solaris 8.
SigmaPi 0.7 & 0.8 bug
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 sigmapi.sourceforge.net
PPC Binary Version
I've included a statically linked Linux-PPC
binary of version 0.7.
I've tested it and it seemed to work
An open, cross-platform journaling program.
A scientific plotting package.
