Can somebody please make a service where we can see live difficulty etc. !?

Hey so this is in a different thread too, but it definitely belongs here:
For SandyBridge CPUs (corei7 with four digit model numbers) running Linux of some sort.
1) git the package.
2) ./configure (screw the flags)
3) gedit Makefile
4) find the line with "CFLAGS = " (there may be flags, there may not be)
5) Change that line to: "CFLAGS = -march=native -O3 -Wall -msse2 -msse3 -msse4.1 -msse4.2 -msse4 -mavx" No quotes.
6) make clean
7) make
start the miner, see how it does!
Brought my performance from 2.6kh/s per core (running one thread per core) to 3.66-3.7kh/s per core.
Tested with 6 threads, +2 kh/s in total.
HT works now!
Just needed some hardcore flags, that's all.
If you have a first generation core i CPU, leave -mavx off the end (ain't no VX), if it won't compile or won't run start cutting the -msse4.x lines off, starting with 4.2, then 4.1, then 4, eventually it'll start working.
Don't forget to make clean then make, if you don't make clean you won't get a new minerd.
I'm going to see if I can make some prebaked windows binaries for various CPUs, I may not have time till monday sometime though, we'll see.
If this works for you, let me know!
If it doesn't, let me know!

Where can I learn more about tenebrix difficulty? I see it is currently 0.19238390

tenebrix miner
Maybe it should be 7777?
Same issue as https://bitcointalksearch.org/topic/m.545153
Ah https://bitcointalksearch.org/topic/m.545449
Instead of 7777 must be 8697
Code:
--url URL
URL for bitcoin JSON-RPC server (default: http://127.0.0.1:8332/)

tenebrix, not tenebrixd ?
Hm... I must be slow today... will look into it tomorrow....

Code:
tenebrix@bitcoindearia ~/bin $ ./tenebrix
bitcoin server starting
Segmentation fault
tenebrix@bitcoindearia ~/bin $ [xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
tenebrix: /var/tmp/portage/x11-libs/libX11-1.4.4/work/libX11-1.4.4/src/xcb_io.c:273: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
Otherwise daemon works nicely.

I already did it for the pool version because some dude from Alaska pecked me oh so hard and oh so systematically over it 
expect all other branches/gits to get updated soon

Any suggestions?
and the bitcoin wx gui always needed wx 2.9 ...
heh, right! I completely forgot to specify bitcoin (or in this case bitcoind)
Perhaps the makefile for the daemon can default to bitcoind instead of bitcoin? And maybe change them to tenebrix and tenebrixd?

Knowing that would have made my life easier! lol

Ahh, you'll need to install libcurl then. After that, there will be libcurl.so at that path.
sudo apt-get install libcurl?

Largely because nobody does a good enough job with search-replace when they release an alt coin.
Actually there is the possible exception of solidcoin, I don't remember bitcoin being in that one. It may have been blanked from my mind by the fail though.

I guess Linux doesn't like me... Happens every time... That's why I still use Windows, at least things make sense to me there...
I'll give it another try tomorrow... Getting square eyes...

Why in the makefile is there still
and
also, compile issues: http://privatepaste.com/c9f75d6086
Code:
all: bitcoin
Code:
bitcoin: $(OBJS) obj/init.o obj/ui.o obj/uibase.o
$(CXX) $(CXXFLAGS) -o $@ $^ $(WXLIBS) $(LIBS)

Sadly no, http://curl.haxx.se/download.html
Then follow the directions in the README.

If it complains about libcurl after telling it to make: Edit the makefile and change @LIBCURL@ to /use/local/lib/libcurl.so
That'll fix it right up.
If it complains about a , when checking for libcurl, edit configure.sh and put a # at the front of the two lines it is annoyed with.
