Re: Using Alien in Ubuntu 10.10

[Luciano de Souza <luchyanus@...>]

Yes, you are completely right. I did:

$ sudo apt-get install libffi-dev
$ luarocks install alien

After it, in /home/luciano/.luarocks/lib/lua/5.1, I found "alien_c.la" 
and "alien_c.so".
I am not a C developer, so perhaps my question sounds for you a little 
bit obvious. In Windows, "alien.dll" is generate. Even though, the name 
is different, in Linux, I found the equivalent file: "alien_c.so". But 
what is "alien_c.la"?
Thank you for the attention and quickness!
