Not compiling typedef definition

Hello,

I´m migrating a VC++ 6.0 code to VS 2010. There is not compiling a file from Visual Studio itself: oaidl.h on the line

Code:

typedef CY CURRENCY;

line 226

it says:

1>c:\program files\microsoft sdks\windows\v7.0a\include\oaidl.h(226): error C2143: syntax error : missing ';' before 'constant'
1>c:\program files\microsoft sdks\windows\v7.0a\include\oaidl.h(226): error C2059: syntax error : 'constant'

any clue?

Yes, some clues :)
Your error means that the type CY is not defined.
It *should* be defined in <WTypes.h>, included in <winscard.h>, that is in turn included in <windows.h>.
You could bypass any of these inclusions by using some preprocessor definitions.
My bet is – you have defined WIN32_LEAN_AND_MEAN. Did I win?

Re: Not compiling typedef definition

Hello VladmirF, thank you for your post!

No, I´ve not defined WIN32_LEAN_AND_MEAN. I defined CY on WTypes.h but it appeared another errors:

this is very strange, a file of Visual Studio itself!

What do you mean - "I defined"???
The type CY *IS* defined in <WTypes.h>, on line # 1051!
Line # 2 in that file has a comment.
Did you type something in yourself?

Yes, there really is.

Yes /* this ALWAYS GENERATED file contains the definitions for the interfaces */

Re: Not compiling typedef definition

Why are you editing a delivered include file?

You can't put the typedef before the definition of "CY".

Re: Not compiling typedef definition

Hello MRViggy, thank you for your post!

I mean, this is a delivered file, why it has compilation errors?

You said:

and

I took that to mean that you hand edited the file. The first three lines in your log lead me to believe that you had added the 'typedef' to the header file before the declaration of "CY".

Re: Not compiling typedef definition

Yes, I set but then pulled off.

I have:

Code:

typedef CY *LPCY;

on wtypes.h:1053

and:

Code:

typedef CY CURRENCY;

on oaidl.h:226

The question is, why this latter is causing compilation errors?:

oaidl.h(226): error C2143: syntax error : missing ';' before 'constant'
oaidl.h(226): error C2059: syntax error : 'constant'

Re: Not compiling typedef definition

I made a simple application with the code:

Code:

#include "stdafx.h" typedef CY; *LPCY; typedef CY CURRENCY; int _tmain(int argc, _TCHAR* argv[]) { return 0; }

and it works!

Re: Not compiling typedef definition

but I´m still needing help on the main application... The error persists.

Re: Not compiling typedef definition

The error message looks like there might be some kind of pre-processor macro defined in one of your header files.

Re: Not compiling typedef definition

Solution: changed for

Code:

typedef CY; //CURRENCY;

may be?

No. That line really says nothing. And, you shouldn't be modifying SDK header files, unless you wrote them. It seems like you might have something in one of your header files, not Windows header files, that might be changing CURRENCY to something else. If you add the compiler option "/E" you can see what the preprocessor is doing. Search the output for "CURRENCY".

As already stated, you are getting errors because you edited line 2 of WTypes.h, which is apparent from the compiler output:

Code:

1>c:\program files\microsoft sdks\windows\v7.0a\include\wtypes.h(2): error C2143: syntax error : missing ';' before 'constant' 1>c:\program files\microsoft sdks\windows\v7.0a\include\wtypes.h(1052): error C2371: 'CY' : redefinition; different basic types 1> c:\program files\microsoft sdks\windows\v7.0a\include\wtypes.h(2) : see declaration of 'CY'

Get a fresh copy of WTypes.h and try again with the unedited version.

Re: Not compiling typedef definition

There was not need to change oaidl.h, it´s just need to add more cpp files in the project.

Thanks :)

I doubt that, but whatever works for you.

Re: Not compiling typedef definition

Yes, you have reason to doubt. The error persists, something is wrong. Any clue, if I change the WIndows SDK???

Re: Not compiling typedef definition

It worked when I altered the order of include afxwin.h to be the first. Strange but works. :wave:
