Title: Need help installing CGMiner on Ubuntu 12.04
Post by: jl2035 on July 21, 2012, 12:00:02 PM
I think I successfully installed the AMD APP SDK (version 2.7) i rebooted the machine and than tried to run...
Code:
CFLAGS="-02 -Wall -march=native"  ./configure
...I get this configure error:

Code:
Configuration Options Summary:
     
 curses.TUI...........: FOUND: ncurses
 OpenCL...............: NOT FOUND. GPU mining support DISABLED
 configure: error: No mining configured in

I have Ubuntu 12.04 32-bit and GeForce 8400 GS graphics card. CGMiner version is 2.5.0.

Please help...

AMD APP SDK is for AMD card (Radeon HD 7970, 6990,...)
You need Nvidia's driver, but it's pointless since with 8400 GS you can only get 2.3 MH/s.
Even if you have 150 computers that use NVIDIA 8400 GS under your control, you can beat it with just one Radeon HD 5850 (350 MH/s).

Oh.. that's disappointing... thanks for your quick reply though...

What about Mobility Radeon HD 4500/5100 Series in my laptop?

Mining on Laptop isn't really recommended, since the speed isn't worth it (you get 50% discount speed compared to desktop version).
Last time I mined on my laptop it instantly shut down because of overheat.
I can't find 51xx series in the wiki.

4570 Mobile : 9.6 MH/s
5870 Mobile :  189.2 MH/s
5870 Desktop : 313 MH/s
