require 'libsvm' fails (MS windows) about rb-libsvm HOT 11 OPEN

I don't have access to a Windows machine, so I can't really help. Patches would be welcome.

I'll look into it. I suppose the module does not compile properly for
windows.

I only have access to windows via a virtual machine. I'll see if I have
everything I need to try to do it.

I installed the libsvm-ruby-swig (0.4.0) gem (both gems installed) and the error changed.

Need MS windows version also

from rb-libsvm.

when You install libsvm-ruby-swig, it loads libsvm.rb file, not extension.
When You have rb-libsvm only - it tries to load libsvm_ext.so but fails on windows

This package, rb-libsvm, doesn't support Windows, unfortunately (unless somebody supplies a patch).

Please note that libsvm-ruby-swig and rb-libsvm packages are alternatives and not meant to be used together.

Just saw that rake-compiler has support for cross-compiling now, and also provides a special rake-compiler-dev-box VM for this. Might make implementing this thing easier.

I don't find the time to do this. So the new status pretty much is: PR welcome.

@jeppevb - Not really an answer to your issue, but I'll share with you my experience. Using Ruby on Windows makes it more difficult than Mac or Ubuntu. I suggest installing Ubuntu in Windows. It is very simple and you do not need dual boot.

@Kraviscloud What is gp?
