[postcd]

I run cpuminer at ARM CPU and it crashes [...]

I have pushed a fix to the git repo, would you be so kind to test it?

Fixed version of cpuminer was tested and it is OK. Thank you!

Question on CFLAGS:

When I configure CFLAGS="-03" is says that "C cannot compile executables"

But if I use "./configure CPPFLAGS="" and then "make" tehre are no errors after the configure command

Does this make any sense and is there any reason NOT to do this when the miner seems to work just fine (sometimes better depending on the pool)?

I put a paste up addressing this issue.

Please not that I am aware of teh typo re: "CPFLAGS" it was supposed to read "CFLAGS"

Would like some feedback

Thanks

When I configure CFLAGS="-03" is says that "C cannot compile executables"

It's "-O3", not "-03". See the difference? (It's big O, not zero.)

Hi pooler,

is there built in support for failover to different configurations if (eg) a p2pool node goes down, or would one need to write their own external script for that?

No native support for that at this point, sorry. See here for some sample failover scripts.

Holy Crap!! That is why it always says that it cannot compile executables!

Thanks Pooler, Ive been doing this wrong for a long time

One other question for Pooler...Will changing my scantime affect performance on older, slower computers?

[pooler]

Will changing my scantime affect performance on older, slower computers?

Brief note on the -s/--scantime option
I have seen people suggest various values for this option in order to reduce stales when mining in pools.
The funny thing is that, to my knowledge, all Litecoin pools have long polling permanently enabled (which is good), and when long polling is enabled the scantime parameter is completely ignored.
For this reason, the use of this parameter only makes sense when you are mining solo.

I am trying to use this software on a work computer that uses a proxy, so I have addded "-x http://<proxy address>:8082"
The output from the terminal says "[2013-07-02 10:17:04] HTTP request failed: The requested URL returned error: 407 Proxy Authentication Required"
The proxy needs me to add a user name, which I do know.
What is the correct format to add my user name to the proxy option to make it work?

http style

I don't understand what you mean.
I have tried using  -x http://<proxy address>:8082:<user name> but this doesn't work.
I need to know the correct syntax to add the user name.

according to rfc: http://<user>:<pw>@<host>[<port>]

according to rfc: http://<user>:<pw>@<host>[<port>]

OK, thanks for your help, I'll try out that configuration tomorrow.
I'm not convinced that it will work though because my username also has an @ symbol in it.

then use the -u and -p for auth and the -o just without credentials

I don't have any problem with the username and password for the pool I am using, I just have a problem figuring out the correct syntax to use with the -x option for the proxy server that that particular computer is using. The proxy username is PUBLIC\*****@LibraryPublic
So you are saying it should look like:
-x http://PUBLIC\*****@LibraryPublic@***.***.***.***:8082 ?

ah right, forgot you need it for the proxy not for the pool auth. in this case there probably isnt a easy solution besides making a hardcoded proxy into minerd or running with proxychains/similiar
are you enforced to use this proxy?

Hi, maybe this is not a perfect thread for this, but anyway... I have a problem with connecting to mine some LTC

You're definitely in the wrong thread. Ask in your pool's thread or in the thread for cgminer, and provide more info about your configuration.

Not perfect? You're using cgminer and pool-x.eu. Hmm, completly wrong thread I would say. 
Anyway, your URL looks wrong - check the postion of "/".
