Title: limker error when using sf::time operators
Post by: okeidar on November 01, 2014, 04:39:38 pm
Hello!
when i use a the operators of sf::time i get the following error
(click to show/hide)

now i have checked the linker settings and i do link it to sfml static libraries and define the precompiled header.
when i use sf::time methods other then the operators i get no messages

Thank you for reading :)

Precompiled header? Do you mean the preprocessor SFML_STATIC define? Also which version of SFML are you using and on what OS? Try getting the latest version and/or compiling from source.

Yes, I meant preprocessor SFML_STATIC, thank you.
i use sfml 2.1 on VS2010 on Windows 7.
I thought i might not have the most recent version so i downloaded the latest.

OK i have changed the calling convention from __stdcall to __cdecl
and it fixed the errors.
can anyone explain how does it matters?

If you set incompatible compiler options you want to get an error, because thats much better than silent corruption at runtime.

yes i understand, but why does sf::time operators work with __cdecl and not with __stdcall?

Because they were compiled that way. (You would need to recompile all libraries with the same setting to make them compatible, but thats much pain for a tiny or possibly even negative gain. You better dont waste time on such microoptimizations.)

Well... there's no reason why a default SFML build wouldn't work with a standard Visual Studio 2010 project. And there's no reason why only sf::Time operators would trigger such a linker error.

I'd say there's something wrong in your environment, but it's hard to say what.

well i  hope ot wont happen again :)
its wierd because i read that windows application should compile with __stdcall and that WINAPI is actually an __stdcall definition..

thanks everybody:)
