Re: [Pharo-users] [UFFI] Using a nested structure

The alignment calculation of external enums is wrong, it should be FFIExternalEnumerationType >> externalTypeAlignment ^ self representationType externalTypeAlignment It only manifests for 32bit platforms on Windows since that's the only one with a pointer alignment (which superclass FF

Re: [Pharo-users] [UFFI] Using a nested structure

Hi Merwan, I tested this on Pharo 6 and it is working in Windows. However, in 32 bits Window doubles have an 8 byte alignment, unlike Linux where they have a 4 byte alignment. Can you try doing the following before performing the ffi call in Windows, if you are moving an image from Linux or OS X:

[Pharo-users] [UFFI] Using a nested structure

Hi, I have an issue whith nested structures. I made some "dummy" structures in c: typedef struct vec3 { double data[3]; } vec3; typedef struct position { int i; vec3 vec; } position; And a "dummy" function to fill it: void fillStruct(position *position) { position -> i = 19;
