PART 2 : Using MSYS and komisar's builds
This will describe a different way to build x264, it was basicaly the way described in the doom10 tutorial, and it's the way i've begun with, and used during a long time. You can use both method on the same PC.
Install of MinGW
Create the following directory : "C:\MinGW"
Get one gcc version
here.
Unpack it inside the "C:\MinGW" directory.
Get the last win32 yasm version
here (actualy when i'm writing this it's the yasm-1.3.0-win32.exe). Rename the file in yasm.exe and put it in "C:\MinGW\bin".
