[Libav-user] compiling ffmpeg 3.0 "Einstein"

[Fermín Ayuso Márquez]

Hi,
I'm trying to compile the new version of ffmpeg using Windows 7 and Visual Studio 2010.
After doing ./config --toolchain=msvc --yasmexe='../dependencies/yasm/yasm.exe' --prefix=ffmpeg/ and make clean, when I do make the following error appears:
CC      libavdevice/alldevices.oalldevices.o_converted.cc:\ffmpeg\libavutil\x86/intmath.h(58) : error C4013: '_tzcnt_u32' undefined;assuming extern returning intmake: *** [libavdevice/alldevices.o] Error 1
I'm using the same scripts that had worked for me in the past.
I use mingw, c99_to_c89_converter and yasm, as I did with older versions.
Can anyone help me?
Thanks.
