Compiling issues with Cuda or COMPILE_GPU=1 #438

Open 770R opened 7 years ago

770R commented 7 years ago

I've been trying to compile the project with GPU usage for a few days now. Found out that a few header files were missing namespace std, that fixed most errors, then it moved on to the last and most annoying error of them all.

Bit of background, originally used OpenCV 3.2 & Cuda 8, then assumed OpenCV might be glitching and recompiled it on version 3.1 & CUDA 8. Tried adding in header file for gpumat, still no luck. Resorting to asking for help. Thanks in advance

Forgot to mention, whenever I tried to cmake it with -DCOMPILE_GPU=1, it always told me "manually set flag won't be used -DCOMPILE_GPU=1". That originally made me assume that OpenCV wasn't correctly compiled. Got around the error by making it default in the code.

matthill commented 7 years ago

It appears that your OpenCV is not compiled with GPU support enabled. That's what the undefined reference messages are saying. You've compiled everything together, but the code is linked to things that don't exist in your OpenCV binaries.

codestamp commented 7 years ago

Just want to ask here whether the gpu support gets enabled if I configure opencv using WITH_CUDA=ON option? I

Friends i have the same problem in a board nvidia tk1 , ubuntu 14 jetpack 3.1
