Running OS X 10.2.4, trying to make use of Akimichi Tatsukawa’s
LibNeural package. I downloaded Swig 1.3.9 and built it from source
(it’s the version listed on the LibNeural page as having been used to
test it), with no errors I could see. The LibNeural package also
built with no errors, but when I ran the test scripts I got a whole
mess of undefined symbol errors like so:
ruby odd_even.rb
dyld: ruby Undefined symbols:

Has anyone run into anything similar on OS X or anywhere else for that
matter? I searched the newsgroup but the only thing I found relating
to LibNeural was a release announcement.
Thanks,

Hi, I’m Akimichi Tatsukawa, the author of LibNeural.
It seems to me that linking to the standard C++ library is not properly done.
In the file ‘ext/LibNeural/extconf.rb’, check out the following option
if it is proper or not under your environment.
$LDFLAGS = “-L/usr/lib -lstdc++”
I don’t know about Mac, so I might give your a wrong advice.

Thanks, Akimichi! I got it working, finally, but it took some doing.
Apple doesn’t include libruby.a in their standard distro, so I had to
build that and install it form 1.6.8, then make the following changes
to the extconf.rb file you pointed at:
$CFLAGS=“-no-cpp-precomp”
$LDFLAGS=“-L/usr/lib -ltinfo -lgcc -lstdc++”
I added this to the RubyOnMacintosh section of rubygarden.org, in case
anyone else could find it useful.
thanks again,
_dave
