Refprop library issue

[Shyamrakr]

I have a c++ program written more than 15 years ago. Unfortunately, the REFPROP.DLL library against which the program was originally linked is old-Refprop7. I won’t be able to use the new version .DLL and .lib as it looks like names of the functions have changed. Any help would be greatly appreciated.

Error-

1>RealFluid.obj : error LNK2019: unresolved external symbol _intsetup_ referenced in function "public: virtual void __thiscall ZAPP::CRealFluid::setUp(void)" (?setUp@CRealFluid@ZAPP@@UAEXXZ)

You will probably need to rewrite your code to match the new API. I don't see any reference to the public API of REFPROP 7, which is what the code should have been targeting back then.
