[TRNSYS-users] TRNSYS17 rebuilding and external dll problem

[David BRADLEY]

Dear Mika,
A DLL can be compiled in either "debug" or "release" modes. I think what 
happened is that your original TRNDll.dll and the Type344.dll that you 
got from Transsolar are both "release mode" dlls. A release mode TRNDll 
looks for external DLLs in the ..\Trnsys17\UserLib\ReleaseDLLs\ 
directory. When you recompiled TRNDll.dll, however, it recompiled in 
"debug mode" (this is a compiler configuration setting) so the new 
TRNDll.dll is now looking for Type344.dll in the 
..\Trnsys17\UserLib\DebugDLLs\ directory and there likely isn't a 
Type344.dll in there. If Type344 does not use any data files then it is 
pretty safe to just move a copy of Type344.dll into the ..\DebugDLLs\ 
directory. If it does use data files then you will need to obtain a 
Type344.dll that is compiled in debug mode instead of release mode.
Kind regards,
David
