I'm struggling with building NLua from source on Windows. It requires a modified Lua version, otherwise my code fails with a missing "lua52.dll". https://github.com/NLua/NLua/issues/53

I tried to get it from here https://github.com/NLua/lua then used "cmake ." and built the resulting "lua.sln" in visual studio.

What happens is that I get a "lua52d.dll" (note the "d"). If I rename it, a "System.BadImageFormatException" is thrown by "KeraLua" (when I try with some "NLua.exe" executable I found in the "tests" folder of NLua).

Can anybody tell me how to build the modified lua52.dll required by NLua? I already have a binary that works but need to be able to rebuild everything by myself. Possibly I'm simply using the wrong source tree.

You're using the right source tree, its just that you're compiling the debug version of the dll, not the release version of the dll. The added 'd' is to denote that it is the debug version of the dll, not the release version.

  • Thanks, switched to "Release" and the "d" is gone. There was one (unrelated) problem with the latest version: lua's _G.unpack has moved into table.unpack, and the exception handler uses it. An "_G.unpack=table.unpack" as first line seems to fix it. – xc6lx45 Sep 02 '15 at 18:57
