\[Solved\] ./cgminer -n: unrecognized option \* This problem was with version 3.8.4

Hi, when trying to set up cgminer i get the following error when testing to see if it works:

./cgminer -n: unrecognized option

I actually get “unrecoginzed option” on every command I try with ./cgminer.

Anyone knows what may be wrong here?

Thanks.

Can you post your input line?

It should look like:

cgminer --scrypt -o http:/ xxxxx -u “USERNAME” -p “PASSWORD” -I “INTENSITY” …

i tried both

# ./cgminer -n

and

# ./cgminer -o stratum+tcp://pool.d2.cc:3333 --scrypt -u x.1 -p x

first line gives “./cgminer: -n: unrecognized option”

second line gives “./cgminer: --scrypt: unrecognized option”

EDIT:
Also in the configurations summary when installing cgminer, I get this:

cgminer 3.7.2

Configuration Options Summary:

libcurl(GBT+getwork).: Enabled: -lcurl
curses.TUI…: FOUND: -lncurses

Which OS do you use?

CentOS 6.0, I followed this guide: https://bitcointalk.org/index.php?PHPSESSID=s3effm7i3mg8ioauuluk2e5v97&topic=170516.0

Tried with xubuntu earlier, but had problems with the ati driver installation.

Some questions:

did you try ‘cgminer --help’?

did you build cgminer on your system or did you download the binary?

it seems, that some compile options are missing in your cgminer.

If you have the sources there should be a configure script. If you open it you can check for the possible compile options and select the ones you need.

I just want to add a comment to this thread as you just solved my problem.
I was trying to get cgminer running on my Windows 7 machine, but it didn’t recognise the --scrypt option.

This problem was with version 3.8.4. Now I downloaded version 3.1.0 as you recommended, and it works as it should :)

Thanks!
