Hello all,

I am a new FANN user and would like to use the self-organizing maps and
growing neural gas code developed this summer, but I don't see it in the CVS
tree. Can somebody point me to the code? Where can I download it, either by
HTTP or CVS (or any other method)?

Thanks,

Ed

Hi,

The som/gng code is in the gsoc2007 (google summer of code) branch.

You can currently check it out using the command:
cvs -z3 -d:pserver:anonymous-***@public.gmane.org:/cvsroot/fann co
-r gsoc2007 -P fann

Got it, thanks! Great work on adding this code, by the way.

One problem: I tried compiling the code into a Windows DLL, but got a bunch
of compiler errors:

C:\Users\Ed\Documents\CProjects\fann-gsoc\src\fann.c:43:19: dlfcn.h:
No such file or directory
C:\Users\Ed\Documents\CProjects\fann-gsoc\src\fann.c: In function
`find_function':
C:\Users\Ed\Documents\CProjects\fann-gsoc\src\fann.c:82: error:
`RTLD_LAZY' undeclared (first use in this function)
C:\Users\Ed\Documents\CProjects\fann-gsoc\src\fann.c:82: error:
(Each undeclared identifier is reported only once
C:\Users\Ed\Documents\CProjects\fann-gsoc\src\fann.c:82: error: for
each function it appears in.)

Can you help me understand what's going wrong?

Thanks,
Ed

It seems that make is not able to detect it is running on windows...

Please try editing fann.c:
find (at the very beginnig) the line

#if ! defined(_MSC_VER)

and change it to

#if 0

It should then work (you are forcing make to disable an unix only feature).

If anyone knows how to preoperly fix it... I'm open for suggestions :-)

Regards
Vincenzo

Hi,

I tried that, but ran into a few more errors.

First, asprintf() isn't defined on Windows systems (at least not in mingw -
maybe somebody can help me here?). I put in a malloc/sprintf workaround,
which may be causing the third error...

Second, there are a bunch of function names in find_function() (the
non-DLOPEN variation) which don't appear to be defined anywhere - I got a
ton of errors when trying to compile, saying things like
fann_layer_constructor_connected_any_any weren't defined. (After commenting
out the guts of find_function(), my DLL would compile, at least...)

Third, when I try to compile the xor test, I'm getting an immediate
FANN_E_CANT_ALLOCATE_MEM error. I believe it's somewhere down in
fann_setup_layer_descr(), when it gets called from within
fann_create_standard_array_typed().

I was able to get the normal CVS files to compile just fine; just not the
GSOC stuff. Any thoughts?

Best,
Ed
