I would like to share with you how I installed LUA on my Edison, and with some help from more experienced Linux users, got it running.
Firstly LUA is a simple, portable, extensible and efficient scripting language widely used in the gaming, mobile device and embedded systems communities. For more information visit www.lua.com . .
From a user with root permissions carry out the following :
Step one - Download the compressed C source code
When the download has finished:-
Step 2 - Decompress the downloaded file
tar zxf lua-5.2.3.tar.gz
Step 3 - Compile and make the file
make linux test
Step 4 Using whatever text editor you like make a text file called hello.lua with the following contents :-
and save it into the /lua-5.2.3/src directory.
Step 5 List the /lua-5.2.3/src directory. You should see this :-
Makefile lcode.o ldump.c llex.h lopcodes.h lstrlib.o luac
hello.lua lcorolib.c ldump.o llex.o lopcodes.o ltable.c luac.c
lapi.c lcorolib.o lfunc.c llimits.h loslib.c ltable.h luac.o
lapi.h lctype.c lfunc.h lmathlib.c loslib.o ltable.o luaconf.h
lapi.o lctype.h lfunc.o lmathlib.o lparser.c ltablib.c lualib.h
lauxlib.c lctype.o lgc.c lmem.c lparser.h ltablib.o lundump.c
lauxlib.h ldblib.c lgc.h lmem.h lparser.o ltm.c lundump.h
lauxlib.o ldblib.o lgc.o lmem.o lstate.c ltm.h lundump.o
lbaselib.c ldebug.c liblua.a loadlib.c lstate.h ltm.o lvm.c
lbaselib.o ldebug.h linit.c loadlib.o lstate.o lua lvm.h
lbitlib.c ldebug.o linit.o lobject.c lstring.c lua.c lvm.o
lbitlib.o ldo.c liolib.c lobject.h lstring.h lua.h lzio.c
lcode.c ldo.h liolib.o lobject.o lstring.o lua.hpp lzio.h
lcode.h ldo.o llex.c lopcodes.c lstrlib.c lua.o lzio.o
Step 6 Test that Lua works :-
root@Tesla:/lua-5.2.3/src# ./lua hello.lua
and you should see this response
Which means all is well
Step 7 You need to tell Linux where is should look for the Lua when you want to run it. This information is stored in the system variable $PATH
to find out what is in PATH on your system type :
At this point you have an number of choices. Either add the current location of Lua to the PATH variable, or move the files to a place already referred to in the PATH variable. You should choose what is best for you. I chose to follow the advice given by deium which is quoted in full :-
"You will have to keep in mind where your space is on the Edison and put as much in the partitions that have your free space.
In the default image, issuing a df command will give you your partitions, you will note that /home has your free space.
In that light, I would move your lua-5.2.3 to /home/lua-5.2.3 and then use a soft link (adjusted from above)
mv /lua-5.2.3 /home
ln -s /home/lua-5.2.3/src/lua /usr/bin/lua
chmod 755 /usr/bin/lua
this way the least amount of space used from /usr/bin is used by the link (which is the root / partition)"
