[TRNSYS-users] new component in C++

no, you don't have to put anything there. That field is there if you want
to be able to execute a compile/link command from within the Studio. If
you are comfortable using your compiler interface, there is no need for
the Studio link.

Please check the trnsys.h file (you can open it with a text editor) and
make sure that both the function GetSimulationStartTime and the subroutine
TYPECK are exported. With some of the early TRNSYS 16 releases, the
trnsys.h file was incomplete and did not have all of the subroutines and
functions exported.

Kind regards,
