 |
|
I downloaded a set of ADO components off the net yesterday. Now I'm
trying to compile a application that uses them, but the compiler is
giving me this error in the .hpp generated by BCB :
[C++ Error] ADOInt.hpp(578): E2040 Declaration terminated incorrectly.
/* safecall wrapper */ inline Word _scw_Get_EOF() { Word r; HRESULT
hr = Get_EOF(r);
System::CheckSafecallResult(hr); return r; }
#pragma option pop
On this line :
__property Word EOF = {read=_scw_Get_EOF};
^ With the cursor over here.
#pragma option push -w-inl
Please tell me what the error is, and how to fix it.
Thank you.

The error probably is that EOF is a Standard Library macro in C++.
I'm not sure about how to fix that. Can you rename this property to a
name that is not reserved?

Would editing the header in any way affect how the library works ? Or,
could I undef the EOF macro ?

The generated header? I have no idea, which is why I posted my
suggestion as a question. I am sure somebody reading this does have an
idea, though.

Fighting against the language one is using is not a good idea IMHO.

I changed the EOF to eof, and now the app compiles and runs fine.
Thank you for your help.

That's better but there is an eof function in the standard library.
You can either ignore the fact that you're using the same name that
the library uses, or you can change names. In a small application, it
may be ok to ignore. In the long run, though, usually things come
back to haunt you.

Yep. Hijacking names from the standard library is evil. Hiding them
is less so, but still problematic.

I think that I'd better change it to EndOfFile or something like that.
