Building with latest version of Cuda and OpenCv

[kasparov92]

Hello,

Have anyone build successfully this repo? it keeps giving me issues when building

Trial 1:
Using Opencv3.4 (latest version to date) gave me an issue regarding the "gpu.h" library, and seems I cannot go with this version as there is not a branch or another code version using this opencv version

Trial 2:
Using Opencv2.4. Well I have cuda 9, so it seems that this version of opencv does not compile with this version of cuda. I also tried to copy the findcuda and detectopencv files from latest version of Opencv, and I had also tried to modify some lines in those files, but all these tricks did not make it work.

So before going further and installing another cuda version and give another try, have anyone tried to build this successfully? and what version of opencv and cuda did you have?

Thanks in advance,
Regards,
Bassel Safwat

Is there anyone who like to contribute the latest version?

@kasparov92 this is likely too late, but - for anyone reading - I did manage to build this repo with OpenCV 2.4.13 and CUDA 10.

To start, in order to use our GPU with OpenCV 2, we have to build OpenCV from source, using the WITH_CUDA=ON flag when we build OpenCV. Otherwise, OpenCV will seemingly build normally but throw CV_GpuNotSupported errors when we actually try to run it. This appears to be the error referenced in #11 and it is described in the OpenCV 2.4 docs here. Instructions for building OpenCV from source can be found here, and the source code for OpenCV 2.4 is somewhere in the OpenCV release archives.

Now we have to install OpenCV! As you mentioned, OpenCV 2.4 is not compatible with CUDA >= 9. This is because CUDA 9 split up the nppi library into several new libraries, and OpenCV 2.4 has trouble finding these new libraries. We have to modify some search paths in the OpenCV makefiles to help it find the new nppi* libraries. This is apparently a pretty well-known issue, and I found this blog post to be the best guide for solving it. This StackOverflow thread contains a similar set of instructions, though it's designed to fix the same issue in OpenCV 3.3.

If you've made it to this point, after editing the OpenCV files as described above and building OpenCV, you should have a working installation of OpenCV 2.4. After that, when building gpu_flow, the gpu_flow makefiles complained about not finding the new nppi* libraries and a few Qt libraries. I fixed those errors by finding those files and appending them to my CMAKE_PREFIX_PATH in the $cmake command. On my machine, my nppi* libraries were hanging out at /usr/local/cuda and my Qt libraries were installed locally at /vision/u/etang21/Qt5.4.2/5.4/gcc_64/lib/cmake/Qt5Widgets. Running cmake with $cmake -D CMAKE_PREFIX_PATH=/usr/local/cuda;/vision/u/etang21/Qt5.4.2/5.4/gcc_64/lib/cmake/Qt5Widgets .. did the trick for me. It looks like the thread in #5 may also be helpful for any errors you encounter here.

Hope this helps in any small way!

I am trying to build OpenCV 2.4 with Cuda-10.2 which is installed on Jetson AGX Xavier. I have followed this blog post in order to change the files so that opencv is able to find all cuda libraries.

System information (version)

• OpenCV => 2.4.13
• Operating System / Platform => Ubuntu 18.04 on Jetson AGX Xavier(aarch64)
• Compiler => gcc/g++(ver-8 as it is supported by Cuda-10.2)

I am running the following command to generate cmake cache:

cmake -DCMAKE_INSTALL_PREFIX=~/lib/opencv_2.4/installed -DCMAKE_BUILD_TYPE="Release" -DWITH_CUDA=ON -DCUDA_GENERATION=Volta -D OPENCV_DNN_CUDA=ON -DCUDA_ARCH_BIN=7.5 -DCUDA_HOST_COMPILER=/usr/bin/gcc-8 -DCMAKE_C_COMPILER=gcc-8 -DCMAKE_CXX_COMPILER=g++-8 ..

Cmake are generated as follows:

I have also tried it with -DCUDA_ARCH_BIN=7.2. I get the same error.
How can I resolve this error?

Thank you

@kasparov92 this is likely too late, but - for anyone reading - I did manage to build this repo with OpenCV 2.4.13 and CUDA 10.

To start, in order to use our GPU with OpenCV 2, we have to build OpenCV from source, using the WITH_CUDA=ON flag when we build OpenCV. Otherwise, OpenCV will seemingly build normally but throw CV_GpuNotSupported errors when we actually try to run it. This appears to be the error referenced in #11 and it is described in the OpenCV 2.4 docs here. Instructions for building OpenCV from source can be found here, and the source code for OpenCV 2.4 is somewhere in the OpenCV release archives.

Now we have to install OpenCV! As you mentioned, OpenCV 2.4 is not compatible with CUDA >= 9. This is because CUDA 9 split up the nppi library into several new libraries, and OpenCV 2.4 has trouble finding these new libraries. We have to modify some search paths in the OpenCV makefiles to help it find the new nppi* libraries. This is apparently a pretty well-known issue, and I found this blog post to be the best guide for solving it. This StackOverflow thread contains a similar set of instructions, though it's designed to fix the same issue in OpenCV 3.3.

If you've made it to this point, after editing the OpenCV files as described above and building OpenCV, you should have a working installation of OpenCV 2.4. After that, when building gpu_flow, the gpu_flow makefiles complained about not finding the new nppi* libraries and a few Qt libraries. I fixed those errors by finding those files and appending them to my CMAKE_PREFIX_PATH in the $cmake command. On my machine, my nppi* libraries were hanging out at /usr/local/cuda and my Qt libraries were installed locally at /vision/u/etang21/Qt5.4.2/5.4/gcc_64/lib/cmake/Qt5Widgets. Running cmake with $cmake -D CMAKE_PREFIX_PATH=/usr/local/cuda;/vision/u/etang21/Qt5.4.2/5.4/gcc_64/lib/cmake/Qt5Widgets .. did the trick for me. It looks like the thread in #5 may also be helpful for any errors you encounter here.

Hope this helps in any small way!

I tried this method. I am able to run cmake without any error (I added the WITH_CUDA=ON flag too). However, on running make, I am getting the following error:

On searching online, I found other situations (ex: this) where this error occurs. However, the solution there involved modifying the Makefile.Config file. There is no such file in my case. How do I resolve this error?
I am working on NVIDIA A6000 GPU machine with cuda 10.1 installed.

Hello,

Have anyone build successfully this repo? it keeps giving me issues when building

Trial 1: Using Opencv3.4 (latest version to date) gave me an issue regarding the "gpu.h" library, and seems I cannot go with this version as there is not a branch or another code version using this opencv version

Trial 2: Using Opencv2.4. Well I have cuda 9, so it seems that this version of opencv does not compile with this version of cuda. I also tried to copy the findcuda and detectopencv files from latest version of Opencv, and I had also tried to modify some lines in those files, but all these tricks did not make it work.

So before going further and installing another cuda version and give another try, have anyone tried to build this successfully? and what version of opencv and cuda did you have?

Thanks in advance, Regards, Bassel Safwat

Hi @kasparov92,
Were you able to build this successfully? What opencv version did you use?
