Hi. I've got a simple patch that lets you cross-compile lua
without editing the Makefiles, by only adding a single
variable to the make command line.
diff -ru lua-5.1.3.orig/src/Makefile lua-5.1.3/src/Makefile
--- lua-5.1.3.orig/src/Makefile 2008-01-19 22:37:58.000000000 +0300

# Your platform. See PLATS for possible values.
PLAT= none
-CC= gcc
+CC= $(CROSS_COMPILE)gcc
CFLAGS= -O2 -Wall $(MYCFLAGS)
-AR= ar rcu
-RANLIB= ranlib
+AR= $(CROSS_COMPILE)ar rcu
+RANLIB= $(CROSS_COMPILE)ranlib
RM= rm -f
LIBS= -lm $(MYLIBS)
Now to compile lua for, say, the ARM architecture, you perform
make linux CROSS_COMPILE=arm-linux-
Assuming your arm cross-toolchain has the arm-linux- prefix.
The default behavior should not change, and you should compile
natively if the CROSS_COMPILE variable is not set.
Please consider for mainline inclusion.
