I got bitten with this recently; it does use -lmsvc80 by default.
However, there is a way to make that dependency go away with the
LuaRocks that comes with the LuaDist batteries (exact location of
config.lua is given by just running 'luarocks')
-- d:\kool\lua\etc\config.lua
variables = {
MSVCRT = 'm', -- stop us linking against msvc80
LIBFLAG = '-shared -Wl,-s ', -- strip by default
LUALIB = 'liblua.dll.a',
}
You can ignore that LUALIB (LuaDist has its own naming peculiarities)
but linking against libm.a seems to be harmless and doesn't make the
DLLs any bigger. So with LuaFileSystem the built-in build looks like
this:
mingw32-gcc -O2 -Id:/kool/lua/bin/../include -c src/lfs.c -o src/lfs.o
mingw32-gcc -shared -Wl,-s -o lfs.dll src/lfs.o
d:/kool/lua/bin/../lib/liblua.dll.a -lm
But note the name of 'gcc' - this doesn't work with mingw64. However,
adding these variables restores sanity:
CC = 'gcc',
LD = 'gcc',
To return to the topic, LuaSocket doesn't work, because it's a
makefile rock, and then the default action messes us up:
mingw32-make: Makefile.win: No such file or directory
mingw32-make: *** No rule to make target `Makefile.win'. Stop.
It's entirely possible to do a LuaSocket rockspec which _just_ uses
the builtin build type. I'll post this if there's any interest.
