YASM & NASM
From MythTV Official Wiki
Summary
YASM and NASM are assemblers needed by other builds tools for compilation.
Install YASM
You want the Win32 .exe (for general use on 32-bit windows) (we don’t currently support win64 due to msvc lack of support for inline assembly)
yasm-1.2.0-win32.exe
Save the downloaded exe into a location you will add to the path.
Rename yasm-1.2.0-win32.exe to yasm.
Tip: I created a Tools directory which I placed all the standalone exe’s. Just make sure to add the tools directory to the system path!
Install NASM
You can either install the full version from http://www.nasm.us/
- Go to the win32 folder of latest version on the downloads page
- Download and run the installer
- The only item that needs to be installed is NASM itself. Other items can be left unchecked
-or-
Make a copy yasm.exe and rename it nasm.exe, as they are compatible.
Just make sure with either approach, nasm is available in the system path.
