Hello.
I'm plan to use the ann "Neural Network" on my linux (Ubuntu onerirc).

The first thing is that I couldn't find the ann library in the pd-extended extra folder.
So I downloaded "ann" from http://puredata.info/Members/dmorelli/ann/ann/
and I copied the unpacket folder to /usr/lib/pd-extended/extra

Then I downloaded FANN-2.2.0-Source from http://sourceforge.net/projects/fann/files/latest/download and did:
cmake
sudo make install
the library installed without showing any error.

Then I went to
/usr/lib/pd-extended/extra/ann/src and did:
make -f makefile.linux annmake -f makefile.linux ann

I get the error:
ann_som.c:1:0: error: CPU you selected does not support x86-64 instruction set
make: *** [ann_som.o] Error 1

Any suggsestion?
Thanks Martin

i tried to compile it, and had the same error. Just remove -march=pentium3 from the makefile.

Thanks, now the" make -f makefile.linux ann" compiled without getting any error, but still the "ann_mlp" object is in red.
Is this a path question? I put ann in the search path but ann_mlp stays red.
Thanks Martin

i put
[path /usr/lib/pd-extended/extra/ann]
and got
/usr/lib/pd-extended/extra/ann/ann_mlp.pd_linux: /usr/lib/pd-extended/extra/ann/ann_mlp.pd_linux: undefined symbol: fann_create_array
when trying to invoke [ann_mlp]

My path is the same: "path /usr/lib/pd-extended/extra/ann", but I get two errors:

Gem: can't load library
libdir_loader: added 'cyclone' to the global objectclass path
ann: can't load library

Gem (I suppose) has nothing to do with the ann library.

Solved.
I copied the file "ann.pd_linux" from the /local/lib/pd-extended/extra/ann/src folder
to /local/lib/pd-extended/extra/ann

in the src folder type:
sudo cp ann.pd_linux ../../

Now it works

Hi all, this is my first post in this forum.

Anyway, I have tried in these days to install Ann, but on Mac OSX.
Apparently everything is ok, but when I run the examples pd give me an error: error creating the ann...What do you think?

Because in pd-extended Ann is already in the 'externals' folder...and I don't know...
I have compile everything before.

thank you in advance
