17:42:30Bikeso i declared this new function in external.h and symbols_list.h, going off the example of do_deftype, which is in there despite not having a C definition that i can see, but when building ld complains about undefined references to ext_type_expand
17:45:34jackdanieldo-deftype is defined in lisp, that definition is transpiled by ecl to have a C definition in core and the name in symbols_list.h denotes the name
17:46:00jackdanielyou probably should define it as si_type_expand for sake of the name-mangler comfort
17:52:19jackdanielthat might have confused the name mangler (I know that this should be grasped by the mangler from definitions but the name translation is rather a mess)
