Hi Esteban,

Previously, I was doing with NB something like this:

pointer := NativeBoost allocate: 4.

self��primitiveWhatever:��pointer

and:

primitiveWhatever: pointer

<primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode >

^ self nbCall: #( int void (NBExternalAddress pointer ) )

But of course that doesn't work with latest FFI. So I tried instead:

pointer := ExternalAddress allocate: 4.

primitiveWhatever: pointer

<primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode >

��^ self nbCall: #( int void (ExternalAddress pointer ) )

But then I get a ExternalAddress class #asExternalTypeOn: ��which is sent in FFICallout >>��resolveType:

Any idea how can I use ExternalAddress in the signature of the FFI primitive call?

What am I doing wrong?

Thanks in advance,��
