Perhaps you can be a little more specific about the failure.

Using MinGW/MSYS I built sqlite-3.3.4 from sources; you can look at
the sqlite mailing list archives to see the minor changes needed to
build the DLL with MinGW/MSYS
or you can just get the pre-built DLL from the sqlite web site.

After making sqlite, I placed sqlite3.dll in /usr/local/bin and
sqlite.h in /usr/local/include (note that these are MSYS paths).

Then I unpacked lua-sqlite3-0.3; in the Makefile I changed five
occurrences of ".so" to ".dll" and in the Makefile.cfg I added
-L$(bindir) to LDFLAGS (*), and used -llua51 for LUA_LIBS.


$ make
gcc -g -Wall -I/usr/local/include -c   -o libluasqlite3.o libluasqlite3.c
gcc -L/usr/local/lib -L/usr/local/bin -Wl,-rpath,/usr/local/lib -shared   -o libluasqlite3.dll libluasqlite3.o -llua51 -lsqlite3
m4 -DSHARED_LIB_PATH=/c/Dev/lua/lua-5.1/modules/lua-sqlite3-0.3                 \
        < > libluasqlite3-loader.lua
m4 -DSHARED_LIB_PATH=/usr/local/lib/lua                         \
        < > libluasqlite3-loader.lua.install

I had to edit libluasqlite3-loader.lua for three reasons:

1. It assumes the ".so" name, so I changed it to ".dll"

2. It puts an MSYS path in the file instead of a Windows path, so I
manually fixed shared_lib_path.

3. For 5.1 I changed loadlib to package.loadlib

(*) I have lua51.dll and sqlite3.dll in /usr/local/bin because the
Windows path to /usr/local/bin is in my PATH so Windows can find the
DLLs to load them
