Here's how windows users can compile a more optimized / cpu specific build of slimminer for the main pool when its back up.
1 - Download and run Cygwin installer: http://cygwin.com/install.html > 'Cygwin Setup' folder on C:
2 - Ensure that you add the following extra packages to the 'default' install from the menu settings window (a few tabs into the install process);
devel / gcc-g++
libs / libcurl-devel
devel / automake
devel / make
archive / unzip
net (web) / wget
devel / git
net (web) / openSSL-devel
Remember to add: "automake: Wrapper scripts for automake and aclocal" - along with the latest auto make release - or slimminer won't compile.
3. Start the Cygwin terminal from the desktop shortcut you created at install. Now copy and paste the following:
Code:
git clone https://github.com/siklon/slimminer
Code:
cd slimminer
Code:
chmod +x autogen.sh
Code:
./autogen.sh
Code:
CFLAGS="-O3 -march=native" ./configure
Code:
make
Check for errors during the process, however your minerd.exe (slimminer) should now be built in;
C: > cygwin64 > home > 'account name' > slimminer
4. You can start mining from the Cygwin Terminal. Ensure that you cd into slimminer dir after starting the terminal window with;
Quote
cd slimminer
Quote
./minerd.exe -a dcrypt -o stratum+tcp://POOLADDRESS:POOLPORT -u YOURWALLET -p x
Remember to set the correct pool address, port and your own wallet address. You can also add -t 'number of cores'.
--scantime 15 (is probably optimal for pool mining) and --retries -1 will try to resubmit shares if the connection drops.
...
To get an optimized build of slimminer for your chipset you need to change -march=native before compiling slimminer.
For an i7 :
Code:
CFLAGS="-O3 -march=corei7" ./configure
Those values can be found at: http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86-64-Options.html#i386-and-x86-64-Options
Just delete everything in the slimminer folder if you want to recompile whilst trying to find the fastest CFLAGS for your chipset.
N.B. your miner will be dependent on your cygwin environment and is therefore not a standalone miner, but it will be optimized for your chipset and should certainly be much faster. You can also compile a working 32bit slimminer on windows this way.
Good Luck.
