opencl_load: could not link. error: CL_INVALID_LINKER_OPTIONS

[Grench6]

OS: Ubuntu 20.04.1 LTS

I have a RTX580, so I am using rocm and the opencl it comes with. I have successfully built darknet, but whenever I try to run it I get the following output:

user@user-pc:~/darknet-1.2$ ./darknet detector demo cfg/coco.data cfg/yolov3.cfg yolov3.weights
Device IDs: 1
Device ID: 0
Device name: gfx803
Device vendor: Advanced Micro Devices, Inc.
Device opencl availability: OpenCL 1.2 
Device opencl used: 3137.0 (HSA1.1,LC)
Device double precision: YES
Device max group size: 256
Device address bits: 64
opencl_load: could not link. error: CL_INVALID_LINKER_OPTIONS
CL_PROGRAM_BUILD_LOG:

user@user-pc:~/darknet-1.2$

What am I doing wrong? Does opencl_load: could not link. error: CL_INVALID_LINKER_OPTIONS mean something is wrong with my opencl? or is it the way I built darknet? My google-fu was useless.

Hello @Grench6 Please try the: git apply rocm.patch.txt in the darknet directory From this one file: rocm.patch.txt Thx! Let me know if that works?

Hello @sowson, thanks for the quick response!

This is what I got:

user@user-pc:~/github/darknet$ git apply rocm.patch.txt
error: patch failed: src/opencl.c:309
error: src/opencl.c: patch does not apply
user@user-pc:~/github/darknet$

I don't know why the files differ (only a little bit), since I cloned the main branch. So I manually made the changes specified in the patch... and it worked! 😃

Now I am getting another error, but it has something to do with a failed assertion on opencv, and I am almost sure it is my fault (I had problems installing opencv, so I used a script for and things got messy). I will attach the output just in case:

I see you updated your blog to include the setup for Ubuntu, I will check it out and hopefully my error is fixed. I will close the issue, thank you very much! 👍🏾 💯
