ammer Invalid FFI type for return

I tried to build my project with haxe 4.2.3 I got this error

Any idea what type is causing the error? You would get more information with -D ammer.debug=all.

Also, is this something that used to work with a previous version of Haxe?

The first time I used the library was when it was first announced and i think the tests worked.

I'll use the debug filter and give you feedback

After adding the debug flag, I got these outputs

It seems to be refering to this class

class StellaNative extends Library<"stella"> {
    public static function create_stella_demuxer_ptr():ammer.ffi.Alloc<DemuxerNative>;
    public static function create_stella_demuxer_cb_ptr():ammer.ffi.Alloc<DemuxerCBNative>;

    public static function create_stella_decoder_ptr():ammer.ffi.Alloc<DecoderNative>;
    public static function create_stella_decoder_cb_ptr():ammer.ffi.Alloc<DecoderCBNative>;
}

@Aurel300 what do you think I might be doing wrong?

Aug 31 '21 20:08 darmie

I think I have fixed it... I removed the static functions and used their .alloc respectively... the code built

Aug 31 '21 21:08 darmie

It seems it was a false fix... I am getting this now
