Any and all help is appreciated!

Following the directions on the litecoinpool.org site:

Quote
Linux users: download and compile cpuminer. Under Debian and Ubuntu, you can use the following recipe:
  sudo apt-get install automake build-essential git
  sudo apt-get install libcurl4-openssl-dev
  git clone git://github.com/pooler/cpuminer.git
  cd cpuminer
  ./autogen.sh
  ./configure CFLAGS="-O3"
  make

I get the following after   ./configure CFLAGS="-O3"

See `config.log' for more details

I didn't see anything in config.log that seemed helpful, at least not to a noob.  Do I need to install any random C compiler? A specific one?

Obviously, "make" fails.

Again, thanks for any help!

Do you have gcc installed?

If not, sudo apt-get install gcc

I do/did, and it's at latest version.  Undecided  But it's still very kind of you to reply!

post the output of your config log.  And just for shits and giggles try ./configure without any flags to see if you get any different errors.

After trying your suggestion, I get the following, quite different result (console output).  I am not sure whether that means I am good to go.  I don't know what the flags meant after ./configure. I am in pure monkey-see monkey-do at this point.  Do you think I am good to make?

Does the official cpuminer have the same problem?  Perhaps try avoiding an unofficial version.

Interesting.  I was following the recommendation from http://www.litecoinpool.org/help, which delivered me to an entirely different github, https://github.com/pooler/cpuminer, which upon closer reading is a fork of yours. It claims bitcoin and litecoin capabilities. Was the fork to include litecoin (which is what I am wanting to use a CPU for)?  Does your official miner support litecoin? 

Apologies if these are all really basic questions.  I've been mining bitcoin for a while now, just for fun, using our graphics cards when we're not using the computers.  Mining litecoin seems like a way to use the laptop and/or the other CPUs, and learn more about crypto/alt currencies.  If I can figure it out.

Thanks Smiley

type in 'make' and see what happens.  I think it will compile at this point, it looks like you had a bad flag before.  Worst thing that will happen is it won't build correctly, and you can start again with 'make clean'.

IF it builds than you are good to go with ./minerd and your pool information.

Invocation command line was

  $ ./configure CFLAGS=-03

There's your problem. It should be "-O3", not "-03" (big O, not zero), otherwise gcc won't recognize the flag.

As seen above, the problem you encountered is not a bug, and you would get the same behavior with jgarzik's original version.
My fork just adds support for the algorithm used for Litecoin mining, introduces a lot of optimizations and adds a few extra functionalities.

Thank you!  The change in the flag from 03 (zero three) to O3 (oh three) made all the difference.  I'm out of town right now, but when I get back I'll be working with the problem of minerd not being in the same folder as litecoin-qt.  But I am not the only one to have had that problem, and I feel progress has been made with success just around the corner!
