IUP and Ubuntu

[Dirk Laurie <dpl@...>]

Being curious to see Steve Litt's presentation, I installed IUP.
Not too much joy so far.

My default lua is lua5.1 as supplied in Ubuntu Lucid.
I downloaded iup-3.4_Linux26g4_lib.tar.gz into a new directory.
No instructions, but three files with suggestive names which
I ran in the following order (a typical line of output is shown):

    sudo ./install
...
`libiuplua51.so' -> `/usr/lib/libiuplua51.so'
...
    sudo ./install_dev
...
`include/iup.h' -> `/usr/include/iup/iup.h'
...
    sudo ./config_lua_module
...
`iuplua.so' -> `/usr/lib/libiuplua51.so'
...

Then I tried it out, not getting past square one, thus:  

$ lua
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio
