[TRNSYS-users] proble on rebuilt DLL and LINKCK

[David BRADLEY]

Mehdi,
   Type919 calls a subroutine called AIRPROP (which is part of the TESS 
Libraries). You simply need to add the AIRPROP subroutine to your DLL 
project. I can't tell from your message which Fortran compiler you are 
using. If you are using Intel, simply right-click on the "source files" 
folder of your DLL project, select "add: existing item" and then browse to

..\Trnsys17\Tess Models\SourceCode\DryAirProperties.f90 (if you are 
using Trnsys17)

or to

..\Trnsys16\Tess Models\SourceCode\DryAirProperties.for (if you are 
using Trnsys16)

If you are using the Compaq compiler, the process for adding a file is 
more or less the same. I don't have CVF installed anymore but I seem to 
remember that you can right-click on the source files folder and select 
"add to project" and then browse for the file.
Kind regards,
  David
