[TRNSYS-users] Multiply defined symbols, STEC type 205, dll linking error

[Edward Halawa]

Paul,

 

It looks like the symbol (ENTHALPY) appears (and defined) twice. Check:
if they have the same definition (function, purpose), then disable one
of them (usually the one residing in your program). However if they
serve different purpose then simply rename one of them.

 

Cheers,

 

ehalawa

linking error

 

Hi,

 

I am trying to implement the STEC type 205 (CIEMAT turbine) into my dll
using CVF66 and TRNSYS 16.

The type requires a subroutine called gas.for. I have added the
following line to gas.for to convert it into legacy mode:

 

      !DEC$ATTRIBUTES DLLEXPORT :: GAS

 

It compiles OK but then I do get the following linking error:

 

Linking...
Gas.obj : error LNK2005: _ENTHALPY already defined in Comv-phy.obj
Gas.obj : warning LNK4006: _ENTHALPY already defined in Comv-phy.obj;
second definition ignored
   Creating library Release/TRNDll.lib and object Release/TRNDll.exp
Release/TRNDll.dll : fatal error LNK1169: one or more multiply defined
symbols found
Error executing link.exe.

 

Looks like it clashes with the Type 56 which uses the comv.phy.obj

Can anyone give me advice how to solve this problem?

 

Thanks, cheers
