Darknet: Can't compile with GPU=1 gencode error

[ilyasmg]

Hi,
I'm having this error and I looked the other issues but none had this type of error:
/bin/sh: 1: -gencode: not found
Makefile:92: recipe for target 'obj/convolutional_kernels.o' failed
make: * [obj/convolutional_kernels.o] Error 127

I looked for a file called gencode but I cannot find it
I'm using ubuntu 18.04 + cuda 10.0 + cuddn 7.4
GPU: GeForce GTX 1050

Similar error, ubuntu 18.04 + cuda 9.1; GPU GeForce GTX 1050. Still figuring out if I have cudnn installed properly.

Turns out I didn't install cuda properly. Followed these steps, and got everything to work: https://linoxide.com/linux-how-to/install-cuda-ubuntu/

Hi Thomas - I'm experiencing the similar 'convolutional_kernels.o' failed problem. I'm also running Ubuntu 18.04, but with Cuda 10, GTX 1050. I installed the driver 415.27. Samples seem to work, but darknet fails to compile. Based on what I've read - it should work with Cuda 10 - but I can't seem to resolve this. I checked through the link you provided, and other than the version difference, I think everything is setup correctly. Any ideas? Thanks - Jeff.

1. after cloning darknet, make it with root (sudo)
2. set NVCC = /usr/local/cuda/bin/nvcc
   Your NVCC should match with the cuda library you specify in the Makefile

thank you !

maybe you should use cuda-8.0

Hi,
I'm getting this error.

/bin/sh: 1: nvcc: not found
Makefile:168: recipe for target 'obj/convolutional_kernels.o' failed
make: * [obj/convolutional_kernels.o] Error 127

When I use nvcc --version I get this output
