Hi there!
I'm experimenting with the LUA API atm, but for some reason it doesn't seem to be linking properly. I'm on linux (slackware), and I've compiled and installed the most recent version of lua.

Here's the output:

gcc -o voipscript -llua main.o resources.o siplib.o

main.o: In function `main':

main.c:(.text+0x83): undefined reference to `luaL_newstate'

main.c:(.text+0x9d): undefined reference to `luaL_loadfile'

collect2: ld returned 1 exit status

make: *** [all] Error 1

As you can see, I've linked to lua with the '-llua' switch. Can anyone tell me why it doesn't link properly? (at least I'm assuming that's the problem)

Thanks in advance,
OScoder

GCC don't work that way. You set the object files before the "-o" flag, as well as the library, which goes after the object files, like so:

gcc main.o resources.o siplib.o -llua -o voipscript

Basically, it goes "gcc <.o files> <-l libs> -o <program name>", though it's easier to just do it all from one command line instead of worrying about linking .o files.

gcc -Wall main.c resources.c siplib.c -llua -o voipscript

That should all work!

That's got it :-). Thankyou!
