For the lua compiler build, you'll need to define LUA_OPNAMES in the preprocessor under properties for that project. You might have to do a clean build afterwards, as depending on how you built your solution.

I have one solution, with both libraries, and compiler/interpreter in the one solution. And if you have it setup to put all the *.obj files under Debug/Release it'll see the built opcode.obj file from the library build and not build it for the lua compiler build. So what I like to do is have a them output the build files under Debug/(lua/luac/etc) and the same for Release/(lua/luac/etc).

Some more info for the unintuitive:

If you open up lopcodes.c, you will see where LUA_OPNAMES needs to be defined.

So, in your MSVC C/C++ project options, add this line:

/D "LUA_OPNAMES"

Then recompile your library.
