[Pharo-users] example in FFI manual not worked

[Torsten Bergmann]

Hi Yuriy,

I guess you subclassed your class from the (wrong) class "ExternalStructure" 
but in the
guide it is "FFIExternalStructure".

Make sure to accept in the browser:

   FFIExternalStructure subclass: #MyStructure
     instanceVariableNames: ''
     classVariableNames: ''
     package: 'FFIDemo'

instead of 

   ExternalStructure subclass: #MyStructure
     instanceVariableNames: ''
     classVariableNames: ''
     package: 'FFIDemo'

to make the class MyStructure a subclass of FFIExternalStructure instead of 
ExternalStructure.

Hope this helps!

Bye
Torsten
