• 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.
