[TRNSYS-users] new component in C++

[Wouter Lumen]

David,

Thank you for your answer.


The trnsysfunctions that the compiler doesn't find are in the headerfile.
Even the storage functions that weren't in it originally were added.

I my earlier mail i only gave the types of errors i was getting.
Actually, everytime a trnsysfunction is called upon in the cpp-file I get an
error:
Here's all of them:

1>.\ttestcomp.cpp(155) : error C3861: 'getStorageVars': identifier not found
1>.\ttestcomp.cpp(157) : error C3861: 'setStorageVars': identifier not found
1>.\ttestcomp.cpp(180) : error C3861: 'TYPECK': identifier not found
1>.\ttestcomp.cpp(184) : error C3861: 'setStorageSize': identifier not found
1>.\ttestcomp.cpp(193) : error C3861: 'getSimulationStartTime':  
identifier not found
1>.\ttestcomp.cpp(194) : error C3861: 'getSimulationTimeStep':  
identifier not found
1>.\ttestcomp.cpp(211) : error C3861: 'setStorageVars': identifier not found
1>.\ttestcomp.cpp(227) : error C3861: 'getStorageVars': identifier not found
1>.\ttestcomp.cpp(267) : error C3861: 'setStorageVars': identifier not found

These are all the same type of errors. (this time the file was  
compiled with MSVisualC++2005.)

I have tried 3 different compilers and all of them give these errors.

Could this have to do something with compiler settings?


Thank you.

Kind Regards,
Wouter Lumen
