QuantLib-SWIG 1.1 with Ruby 1.9 on Mac

[Cyprian Kowalczyk-3]

Hello,

I am trying to make QuantLib working with Ruby 1.9 via SWIG.

I have QuantLib and SWIG installed and now trying to install QuantLib-SWIG 1.1.

First I had problem with 'ftools' as it's depreciated in Ruby 1.9 - I used 'fileutils' instead but I get the following error while running 'ruby setup.rb build':

/usr/local/Cellar/quantlib/1.1/include/ql/methods/finitedifferences/finitedifferencemodel.hpp:109: warning: implicit conversion shortens 64-bit value into a 32-bit value

make: *** [quantlib_wrap.o] Error 1

Any hints on whether it's possible at all to make QuantLib talking with Ruby?

Thanks,

Cyprian

I've faced that also on Quantlib Swig-Ruby 1.1 when trying to use ruby 1.9 because of ftools being deprecated.

Did you managed to fix that ?

Is fileutils available in previous Ruby versions, too? (I'm asking
because I'd like the build script to run on multiple versions...)

This is just a warning.  How did it stop the compilation? May you look
at the command line and see if somehow there was a -Werror thrown in?
