[spacer2050]

Hi,
with configure options must i set to compile Qt 4.7.2 with Visual Studio 2010 as a 64-bit version on Windows 7 64-bit ?

Thanks

Juts call configure with MSVS 2010 options.
64 bit should be default on 64 bit machine, isn't it?

No, it is not.
Visual Studio has different cmds for 32bit, 64bit and Itanium, so you need to use the 64bit VS cmd.

//and make sure you installed the patch (for VS2010) that corrects the memory corruption bug about 64bit O2 and structures bigger than 64bit.

Where I can get that patch, do you have link?

[Zlatomir]

"Here":http://support.microsoft.com/kb/2280741 you can find information about bug and link to the patch is in that page too.

Thank you very much.

Also the recently launched "SP1":http://support.microsoft.com/kb/983509 for Visual Studio 2010 list some more fixed issues about x64 (issues with C++ compiler and optimizations)

[Scylla]

So if I have already SP1 installed, the problem should be fixed?

[Zlatomir]

I don't know, they don't specifically say that SP1 include that fix, but that fix is older than SP1 and usually the Microsoft service packs include all older updates and patches - so SP1 should include that too.

Ok, thank you very much.
