Building Lua with Microsoft Visual C++

First, make sure that the SDK’s bin directory has been included in your system’s search path. Under the

SDK’s

include directory, make a subdirectory named usr. Similarly, under the SDK’s lib directory,

make a subdirectory named

usr. Additionally, as covered in the environment section, you should set the

LIB environment variable to the SDK’s lib and lib\usr directories, and the INCLUDE environment

variable to the SDK’s include and

include\usr directories. Your SDK may include a batch file named

vcvars32.bat that can help with this. If you modify these environment variables, exit and restart the

shell to have your changes take effect.

Create a directory in which to build Lua. The following lines assume that this will be

c:\dev:

cd \

mkdir dev

cd dev

Download lua-5.1.1.tar.gz and place it in this directory. Extract the contents. Here are the com-

mands you would use with 7-zip:

7z x lua-5.1.1.tar.gz

7z x lua-5.1.1.tar

This creates a subdirectory named lua-5.1.1. Delete lua-5.1.1.tar at this point, like this:

del lua-5.1.1.tar

Drop into the src subdirectory like this:

cd lua-5.1.1\src

Create a new text file and add the following lines:

cl /MD /O2 /W3 /c /DLUA_BUILD_AS_DLL *.c

del *.o

ren lua.obj lua.o

ren luac.obj luac.o

ren print.obj print.o

link /DLL /IMPLIB:lua5.1.lib /OUT:lua5.1.dll *.obj

link /OUT:lua.exe lua.o lua5.1.lib

lib /out:lua5.1-static.lib *.obj

link /OUT:luac.exe luac.o print.o lua5.1-static.lib

Save the file as build.bat in the current directory (c:\dev\lua-5.1.1\src).

While you’re still in the

src subdirectory, run the newly created batch script from the shell:

build
