Bitcoin mining AMD SDK

UPDATE 7/7/13: If you want to use Catalyst drivers version 12.8 you will find that X won’t start (error msg: /usr/lib/xorg/modules/drivers/fglrx_drv.so: undefined symbol: noXFree86DRIExtension) if you installed CentOS 6.4. Catalyst > 12.8 will work fine. To fix that, you can downgrade to the Xorg version that ships with CentOS 6.3:

yum --disablerepo=\* --enablerepo=C6.3\* downgrade xorg\*
(You may also need to do: yum remove xorg-x11-drv-modesetting)

Do this before you install Catalyst!
UPDATE END.

Here’s my how-to for cgminer / AMD Radeon drivers under CentOS 6.4, 32bit in this example. You can basically copy & paste every line and you should end up with a working mining rig.

Install required packages:

yum install wget system-config-firewall-tui openssh-clients kernel-devel-2.6.32-358.el6.i686 libcurl-devel ncurses-devel compat-libstdc++-33 screen xterm
yum groupinstall "X Window System" "Development tools"

Download and extract cgminer 3.7.2 – later versions don’t support GPU mining:

cd /root
wget
tar xjvf cgminer-3.7.2.tar.bz2

Download AMD APP and ADL SDKs for cgminer compilation from:

AMD APP SDK:
AMD ADL SDK:

Install AMD APP SDK:

cd /opt
tar xvzf /root/AMD-APP-SDK-v2.8-lnx32.tgz
cd /
tar xvzf /opt/icd-registration.tgz
cd /opt
tar xvzf AMD-APP-SDK-v2.8-RC-lnx32.tgz
ln -s /opt/AMD-APP-SDK-v2.8-RC-lnx32/include/CL /usr/include
ln -s /opt/AMD-APP-SDK-v2.8-RC-lnx32/lib/x86/* /usr/lib/

Install AMD ADL SDK:

cd /root
mkdir ADL
mv ADL_SDK_5.0.zip ADL
cd ADL
unzip ADL_SDK_5.0.zip
cp include/*.h /root/cgminer-3.7.2/ADL_SDK

Build cgminer for Litecoin (with scrypt support):

cd /root/cgminer-3.7.2
CFLAGS="-O2 -Wall -march=native -I/opt/AMD-APP-SDK-v2.8-RC-lnx32/include" LDFLAGS="-L/opt/AMD-APP-SDK-v2.8-RC-lnx32/lib/x86" ./configure --enable-scrypt
