Hi,

 

I implemented the FFILibrary way in the latest dev version.

 

Maybe you have to modify the code to point to your library (see RLibrary methods).

 

Don���t hesitate to commit your code, the project is open.

 

Thanks,

 

Cheers,

Vincent

I try to move the R dll close to my Pharo VM and also inside the
Plugins directory but without success ...


It should be at the same location that libcairo.2.dylib


Is there a way to say where are the R dll instead of copying them ?


Are you using the system to do the library path resolution? Or finding the
library file in Pharo and then passing an absolute path to FFI?

 

no, it doesn���t��� you need to pass a path to the library (e.g. '/opt/local/lib/libR.so���)




I think that the system that do the resolution:
I defined in a trait:
ffiLibraryName
        ^ #R
And the library is named R.dll (under windows).

Maybe I should do like CairoLibrary?



My limited understanding is that #ffiLibraryName should return a class
rather than a symbol. Thus...

MyClass class >> ffiLibraryName
         ^ R

R >> win32ModuleName
          ^ 'libr.N.dll'.   "or whatever is the actual dll filename���

 

well��� it can answer a class (a child of FFILibrary, like LibC)

or a String with a fixed path: ���libr.N.dll���

 

of course, 2nd way is limited because you hardcode the library path :S

 

cheers,

Esteban
