Build opencv 3.1 with Visual Studio 2008

edit

With your help I solved errors related to stdint.h and data(), but I still have the error about the __cpuidex and the problem is in modules\core\src\system.cpp. Do you have other suggestions?

is it 64bit on your side ?

My OS is 64bit but I'm trying to compile x86.

can we get the complete error ?

maybe you should make an issue here

This is the complete error: ..\..\..\Development\lib\OpenCV3.1\opencv-master\modules\core\src\system.cpp(298) : error C3861: '__cpuidex': identifier not found and specific line is:

#if defined _MSC_VER && (defined _M_IX86 || defined _M_X64)
        __cpuidex(cpuid_data, 7, 0);

In my case _MSC_VER = 1500 and _M_IX86 = 600.

then i'd say, it's a bug. (there should be code for the _M_X64 __cpuidex case, but there is no such thing here

Thanks! In order to report this bug should I follow the link you posted above?

yes, - https://github.com/Itseez/opencv/issu...

(but, with a grain of salt, -- VS2008 is absolutely low priority, they have no more a buildbot for this, so a fix might take a while)

As a workaround I surrounded the __cpuidex call with:

#if _MSC_VER >=1600
   __cpuidex(cpuid_data, 7, 0);
#endif

In this way since in my case _MSC_VER = 1500 the compiler skip this call, and I was able to compile successfully.

Well, I checked out tag 2.4.9.1 and it compiles beautifully with VS2008 so I'll stick to that for now...
