error while running tbuild command

Hello,
I am trying to build a model from the .c file of a project using the tbuild command of Tornado but I get this error message:

In function ‘void* Create()’:

_Project17_.c:1019:3: error: ‘_LIB_VERSION’ was not declared in this scope

 1019 |   _LIB_VERSION = _SVID_;

      |   ^~~~~~~~~~~~

_Project17_.c:1019:18: error: ‘_SVID_’ was not declared in this scope

 1019 |   _LIB_VERSION = _SVID_;

      |                  ^~~~~~

System error: Externally executed command has returned error code: 256

Does anyone have an idea what the problem could be?
Thanks.
