问题
Finally I compiled it. Main mistake was about VS enviromental variables. To compile and link proper I needed to type
%VisualStudoFolder%\VC\vcvarsall.bat amd64 nmake -f makefile
Default LuaJava distributions provides only 32-bit binaries. Obviously using them with 64-bit VM\OS causes exception.
Also I can't just change Lua binaries to 64-bit, because this causes
Exception in thread "main" java.lang.UnsatisfiedLinkError:
org.keplerproject.luajava.LuaState._open()Lorg/keplerproject/luajava/CPtr;
I don't know why is it so and Google didn't help me.
I've decided it's because 64- and 32-bit libs are completely different, so I must recompile LuaJava and make linking myself.
I downloaded sources from Lua repo at SourceForge (luabinaries/files/5.1.4/Windows%20Libraries/) (btw I tried with different versions, but I have not succeeded), installed MSVS to use nmake utility with Makefiles. Finally I followed guides from "LuaJava Manual" but I got only this:
...\luajava-1.1>nmake -f makefile

Stop.
Also here is luajava.h and luajava.c
So the question is how to resolve that problem (desirable so that it will work with at least LuaStateFactory.newLuaState().openLibs())?
回答1:
I have encountered this problem, but later resolved. Here is the solution.
I've managed to compile a 64-bit luajava-64.dll, 64-bit luajava-64.so, 32-bit dynamic link libraries, and so on.
Here are the steps.
1. Install vs2010
2. Locate vs2010-visual studio tools
Open visual studio x64 Win64 Command Prompt tool
3. Download lua-5.1.5_Win64_vc10_lib.zip
. (Static library wrong key point is that this static library may download error, or you download as a dynamic library dll, download address: lua static library download:
http://sourceforge.net/projects/luabinaries/files/5.1.5/Windows%20Libraries/Static/)
Download luajava-1.1.zip
4. Open config.win modify LUA_DIR and JDK two paths for their own path
Note that you may not have your LUA_DIR below lib directory, then create your own needs and into which lua5.1.lib
5. cd enter luajava-1.1 directory
6. Run nmake -f Makefile.win
7. Compile success
Here is the situation at compile time:
