Re: [TRNSYS-users] new component in C++

[Wouter Lumen <wouter.lumen@ugent.be>]

Dear Werner,

Thank you for your reply.

It probably has something to do with the headerfile indeed.
The statement #include "trnsys.h" is in the sourcefile!
So far i have used 2 trnsys.h files: one I copied from the trnsysfolder and
one i got from somebody else who used it to compile his component.

I'm gonna try to get somebody with more C++ experience have a look at it.

Kind Regards,
Wouter
