Using IUP with Lua on Ubuntu

I'm trying to get IUP working on Ubuntu. I downloaded the binaries from sourceforge and the libraries seem to be in place in /usr/lib/libiup*.so, but when I wr开发者_C百科ite a script like the following:

require("iuplua")
iup.Message('Testing App!', 'Finished Successfully!')

I get an error:

lua: attempt to call a nil value
stack traceback:
    [C]: ?
    [C]: in function 'require'
    test.lua:1: in main chunk
    [C]: ?

Looking into it, I saw a message noting that someone seemed to have fixed it - their "LD_LIBRARY_PATH did not point to the right cd and im directories" or something similar. I couldn't seem to correct my problem w the LD_LIBRARY_PATH environment variable. I saw another note from 2008 saying that the "IUPLua binaries have hardcoded lua bytecode that is causing the error". I tried to compile from the sources, but I'm getting errors related to cd.h.

Any help would be -greatly- appreciated. Thanks!

Here is something you can check out, perhaps it will help.

When you load a module with require Lua uses the package paths to determine where to look for the module.

package.path: Where Lua looks for .lua modules
package.cpath: Where Lua looks for .so/.dll modules

Have a look at this section of the Lua manual: Modules. Specifically, the section on package.path and package.cpath.

You can check what the current paths are like:

print(package.path.."\n"..package.cpath)

You can append the paths like:

package.path = package.path..";/usr/lib/?.lua"
package.cpath = package.cpath..";/usr/lib/?.so"
