__forceinline

[noble]

does anyone know if the __forceinline declaration is part of the
SDK or something? I'm attempting to build a project and it's
complaining about every occurrence of __forceinline. i did not find
documentation for this in the packaged MS help files.

any help on this would be greatly appreciated

what version of MSVC are you using? if you aren't using MSVC then its inline

[noble]

i'm using msvc 5 but i know the project was created in msvc 6

i attempted to use the lib file from it but i have to build a version
of the dll so i can use the lib with vc 5.

it complains heavily of this function

[kedaman]

hmm i don't have msvc5 but i guess it doesn't have __forceinline then, you can always try inline instead, what does it say?

[noble]

First it complains about the __forceinline declaration
the errors following are probably a result of the __forceinline
error but here's the specific error for __forceinline


buffer.h(22) : error C2501: '__forceinline' : missing decl-specifiers



if i replace all occurrences of __forceinline with the inline or
__inline declaration, i get 100 or more errors that complain
that there are errors in the atlctl.cpp file which i never even touch.

ghey

thx for any help

[CornedBee]

Maybe ATL changed from VC5 to VC6? Few compilers provide upward-compatibility ;)

inline is a C++ keyword
__inline is a VC6 keyword (works in C too, does not work in VC5)
_inline is a VC5 keyword (works in C and VC6 too)
__forceinline is a VC6 keyword (works in C too, does not work in VC5)

[CornedBee]

But if you want a lib with downward compatibility to VC5 you can create it in VC6 with this linker option:
/LINK50COMPAT

This will tell the linker that the lib must be compatible with VC5

[noble]

thx for your help cornedbee, i will submit a request for the
author of the program to make it 5.0 compatible
