Hello,
Is it possible to call a Ruby method from a native extension without using the callback system ?
Thanks,
Louis

Hi Alex,
And how can I call this from Objective-C / Java extension implementation ?
My need would be to call a Block Proc passed to my native extension but asynchronously.
Something like that :
# Initialize my native extension and wait for asynchronous events
Rho::NativeExt.initialize()
# Set the callback Block which will be called by the native extension when some event is triggered
Rho::NativeExt.callback do |object|
end
So I'd need to retain the Block passed in parameter and then call it when a certain event occurs.

ObjectiveC naively supports interoperability with C language.
For Java you probably will need to use JNI.
I can't tell what exact calls to VM you should make to process a block. It is something I'd recommend to look for in Ruby/MRI community.

I'm trying out the native extension example from the website (Greeting extension). I have followed all the steps but when i try to compile the application getting below exception.
Don't know how to build task 'project_path/bin/tmp/greeting/arm/Greeting.cpp.o'
Is there something I'm missing out on.
Thanks Before.

Just to add that all the other extension that come with Rhomobile are compiling correctly. Tried even the crosswalk extension at it seems to have no issue. Using rhodes-oss version 5.5

Rajiv,
check if letter case of source filenames on filesystem corresponds to filename list in project files
