| Subject: | XS code does not compile with most FANN versions |
I tried to compile AI::FANN using the CPAN shell with two different
versions of
libfann and got similar compiler errors from different places each time.
This is using perl 5.8.8 on Debian Lenny/x86:
Using libfann1 1.2.0-1 included with Debian (also tried with the
download from
http://prdownloads.sourceforge.net/fann/libfann1_1.2.0-1_i386.deb?download):

Looks good

It seems all the header file are being found (of course I installed the
corresponding -dev .debs) but the symbols aren't defined anywhere. I
can't find them anywhere in my /usr/include.
