Hi,
I got a problem instaling Algorithm::SVM
but the fix is trivial: add:
#include <cstring>
in bindings.cpp (just after <errno.h>)
cp lib/Algorithm/SVM.pm blib/lib/Algorithm/SVM.pm
AutoSplitting blib/lib/Algorithm/SVM.pm (blib/lib/auto/Algorithm/SVM)
cp lib/Algorithm/SVM/DataSet.pm blib/lib/Algorithm/SVM/DataSet.pm
Running Mkbootstrap for SVM ()
chmod 644 "SVM.bs"
"/usr/bin/perl" -MExtUtils::Command::MM -e 'cp_nonempty' -- SVM.bs
