rubygems - Using FFI (gem) or similar in Rubymotion -

i have external c-library want use rubymotion (redpotion) project. have used library ruby project , used gem ffi, worked great.

however can't gem work in rubymotion (properly because not rubymotion gem). error.

uninitialized constant libdedx::ffi (nameerror)

the gem included in gemfile , code below

module test     class dedx_workspace < ffi::struct         layout  :loaded_data, :pointer,                 :datasets, :int,                 :active_datasets, :int     end end 

does know if possible or know way of using external c-library?

you won't able use ffi. however, there's great way use c libraries.

just wrap c functions in objective-c class , statically link in.

@interface mywrapper : nsobject - (void)somemethod; @end   @implementation mywrapper  - (void) somemethod {     // c stuff here }  @end 

in rakefile

app.vendor_project('vendor/mywrapper', :static)
