modules/speech_to_text/register_types.cpp:2:10: fatal error: 'object_type_db.h' file not found

If you get this error modules/speech_to_text/register_types.cpp:2:10: fatal error: ‘object_type_db.h’ file not found you need to do this :

Introduction – modules/speech_to_text/register_types.cpp:2:10: fatal error: ‘object_type_db.h’ file not found

Go into directory source of GODOT and modules/speech_to_text :

File to open is register_types.cpp

You will see use of a header file

#include "object_type_db.h"

It changes between GODOT 2 and 3 from object_type_db.h to class_db.h

So chang it by :

#include "core/object/class_db.h"

Save and execute GODOT source compilation again it will works.

I get similar error on

modules/speech_to_text/stt_config.h:4:10: fatal error: ‘core/resource.h’ file not found

You need to open modules/speech_to_text/stt_config.h and modify :

#include "core/resource.h"

By :

#include "core/io/resource.h"

Also i get modules/speech_to_text/stt_error.h:4:10: fatal error: ‘core/object.h’ file not found

so i do the following in stt_error.h :

#include "core/object.h"
#include "core/ustring.h"

#include "core/object/object.h"
#include "core/string/ustring.h"
