 |
|
Hi,
Did someone was trying this "dirty trick"?
| Quote: | | If you use gcc 4.9, cuda may not work, complaining that it does not support gcc-4.9 and higher. However, gcc 4.9 happily works after a simple dirty hack: in a file /opt/cuda/include/host_config.h |

| Hi, I modified that header file for cuda 6.5.19 and it has been working without problems. |

How you did this? As I was trying to modify a file from link example, but I do not have this file: /opt/cuda/include/host_config.h |

That header file belongs to nvidia-cuda-toolkit, did you install it along nvidia-cuda-sdk?
| Code: | equery b /opt/cuda/include/host_config.h

dev-util/nvidia-cuda-toolkit-6.5.19 (/opt/cuda/include/host_config.h) |

No, but when I woud like to try, gcc-4.8.5 will be installed as well. Will it affect my gcc 4.9.3 already installed?
| Code: | # emerge -p nvidia-cuda-sdk
These are the packages that would be merged, in order:

It should be possible to install gcc-4.8.5 without affecting the already installed gcc-4.9.3 as gcc is slotted. You can then change the active gcc profile with gcc-config.
An alternative if you can is to unmask nvidia-cuda-toolkit-7.5.18 and nvidia-cuda-sdk-7.5.18 which depend on gcc < 5. |

| The only way I could get nvidia-cuda-sdk-6.5.14 to install was to recompile freeimage using gcc-4.8.5, the compile cuda with gcc-4.9.3. |

| @Xywa, You are installing dev-util/nvidia-cuda-toolkit-7.5.18-r3 from the cg overlay, dev-util/nvidia-cuda-toolkit-7.5.18-r2 on the official tree depends on gcc < 5. |

How is this possible?
I have:
| Code: | # layman -l
* cg [Git ] (https://github.com/brothermechanic/cg.git |
but I masked:
| Code: | # cat /var/lib/layman/make.conf
PORTDIR_OVERLAY="
/var/lib/layman/cg
$PORTDIR_OVERLAY
"
|
And I did something for steam client:
BTW: I masked taht package and the same:
| Code: | # emerge nvidia-cuda-sdk

| According to the Portage output, that repository uses the name cg, but you masked all packages from the repository named cgme. |

Right, some king of error - thanks for the help. [SOLVED]
BTW: Do you think I have "a working OpenCV-OpenCL" now, as one developer is asking me for this (I have problem with slowmovideo & v3d)?
