cgminer 没有找到设备

当我运行 cgminer -n（版本 3.12.2）时，我得到：

 [2014-02-12 11:09:10] USB all: found 12 devices - listing known devices                    
 [2014-02-12 11:09:10] No known USB devices

当我运行 lcpci -v 时我确实看到了我的卡：

03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Antilles [Radeon HD 6990] (prog-if 00 [VGA controller])

fglrxinfo 的结果是：

display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6900 Series  
OpenGL version string: 4.2.12337 Compatibility Profile Context 13.101



display: :0  screen: 1
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6900 Series  
OpenGL version string: 4.2.12337 Compatibility Profile Context 13.101

当尝试使用 ./autogen.sh （带或不带 --enable-opengl）进行编译时，我得到

  OpenCL...............: NOT FOUND. GPU mining support DISABLED
configure: error: No mining configured in

答案1

正如 dobey 所说，我需要 opencl，但 amd-sdk 版本的 opencl 似乎不适合我（我可能安装不正确）。大多数 opencl 安装都会卸载 fglrx 并安装 nvidia 驱动程序。这是我在论坛上找到的一个可以让它工作的：

sudo apt-get install ocl-icd-opencl-dev

希望它能帮助别人！
