Code::Blocks 13.12
TDM-GCC TDM64 MinGW-w64 4.9.2 64-bit
SFML GCC 4.9.2 MinGW (SEH) - 64-bit
Windows 7 64-bit

Just following the instructions on this tutorial page: http://www.sfml-dev.org/tutorials/2.2/start-cb.php

it compiles and runs and says

sfmltest.exe - Application Error
The application was unable to start correctly (oxcooooo7b). Click OK to close the application.

Googling the error (which you should have already done), I found that one cause could be a 32-bit/64-bit clash.
Are you sure your OS, compiled code, and the libraries that you're including are all equal?

If you are sure, read the rest of this article (it was the first result I got from googling that error). It could give you some clues.

I suspected that. That's why I posted my compiler version and SFML version - both 64 bit.
What else could i be missing that might be trying to use 32-bit?

[beauxq]

I compile other code in the same environment and it works fine.
It's just when using SFML, that I get this problem.

[beauxq]

If i use a 4.7.1 compiler, then I can get SFML to work, following the same tutorial.

But for what i want to do, I need 4.9.2

[Hapax]

Are you sure that your SFML libraries are also the 64-bit version? If the problem only occurs when SFML is involved, it's worth checking for certain that they are the exact version required.

Did you read that article that I linked? It suggests many other possible solutions, such as reinstalling IDE or running as admin.

[beauxq]

I just discovered that if I purposefully mix wrong versions, it works.

I put the

4.9.2 64-bit compiler together with the
4.7.1 32-bit SFML,

and the program ran correctly.

I guess I could keep trying to use it like that. I don't know what problems I might come across later from mixing them.

But I can't find any way to get the 4.9.2 SFML to work.

Did you accidentally put an -m32 switch when building your app, making it behave as 32bit compiler?

[dabbertorres]

iirc, TDM-GCC doesn't provide a SEH version of the compiler, only SJLJ and DW2, I think that's the reason here. You should just try compiling SFML yourself.

[wintertime]

It does use SEH in 64bit mode: http://tdm-gcc.tdragon.net/quirks
I would clean the system and then only install one version of the compiler, library, dlls.

It does use SEH in 64bit mode: http://tdm-gcc.tdragon.net/quirks

I guess there's an error then on the SFML download page. The TDM 4.8.1 x64 is using SEH.
Will fix it later today.

As for topic: Either use the builds that 100% match your compiler OR build from source, everything else will fail sooner or later.
