There has been a change in how the constant values needs to be declared (because in a 64bit environment, you cannot “guess” the type by its value: 42 can be (int32)42 or (int64)42. Hence, you need to be explicit on the time.
That’s why @tbrunz suggestion is accurate. Now, I remember writing that example years ago, but I do not remember where :P Can you point me to the source, so I can correct it ? (it should have been done before, but better later than never ;) Esteban > On 1 Apr 2020, at 06:57, tbrunz <wild.id...@gmail.com> wrote: > > Try using this expression: > > ^ self ffiCall: #( int abs ( int TheAnswer ) ) module: LibC > > i.e., add 'int' to tell Pharo that 'TheAnswer' is to be interpreted as a C > integer. > > > > > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html >
