Transition to 1.9 - DL/CPtr issue
I am trying to transition an app to Ruby 1.9 from 1.8.7. This app is calling a shared lib (.so) and it does not work (at all) anymore with the new Ruby.
The reason is there is no more to_ptr with DL in 1.9, but I am struggling to replace it. For instance I had:
extern "bool mclInitializeApplication_proxy(const char**, size_t)"
and in Ruby:
options = ["-nojvm"]
In the Ruby std doc, there is an example:
extern 'double sum(double*, int)'
a = [2.0, 3.0, 4.0]
sum = LibSum.sum(a.pack("d*"), a.count)
so I thought:
would work but it does not (segmentation fault).
Any help would be greatly appreciated, documentation on the new DL is quite limited...
