I don't know where I can find your FAQ.
see my sig.
By the way, I asked if someone could tell me where I can download because I
know that your inclde may be useless on my pc,
Firstly an include file contains only the function declarations. You
will also need the library file. Thats probably copyrighted and only
available if you buy the s/w.
Secondly, there's probabably a million files called config.,h (I have
about ten myself, all totally different). Since its not a standard
header, everyone can write their own.
So you are totally wasting your time. If the source is from a gnu
archive, you need to go and ask the gnu boys. Otherwise ask the people
who wrote the code.
