Question

I am attempting to follow the besic guide given here on embedding lua into C. I copied the code verbatim into my own embed.c file and executed the exact compiler command listed:

cc -o embed embed.c \
            -I/usr/local/include \
            -L/usr/local/lib \
            -llua -llualib

I get the error:

embed.c:19:14: error: invalid storage class for function ‘openlualibs’

After which I moved the functions outside of main, compiled again, and got:

/usr/bin/ld: cannot find -llualib

I am at a loss for why I cannot compile this. lua is installed properly. has anyone else encountered these problems? If this is a bad tutorial, please feel free to simply direct me to a batter one.

On some Linux distributions you may need to install the lua-devel (or similar named) package, in order to get the proper header files and library symlinks required for compiling and linking projects against the package. If you do have a liblualib-<version>.so.<version>, for example liblualib-5.so.5.0, you may need to install the devel package.

Starting with lua 5.1, liblualib does not exist. Here is the release announcement: http://lua-users.org/lists/lua-l/2005-05/msg00186.html
