the suggested config to try this project?

[raymond00000]

HI,

I spended few weeks but still I cannot install IMAGEUTILITIES. I decide to start everything from scratch again. Can you recommend the ubuntu version, openCV version, cuda version, that proved be working config for install this project?

Thanks.

Hi, I'm sorry to hear that, ususally Imageutilities should be much easier to install. We are using 14.04 and 16.04 with OpenCV 3.x (some installed it from source, but you can also use the built-in version of 16.04, the one of 14.04 is too old), CMake 3.2 or bigger.

The problem with your machine seems to be that OpenCV can not be found by CMake. If I do ccmake instead of cmake, I can see the following set variable: OpenCV_DIR=/usr/local/share/OpenCV. How does it look on your machine?

And since this has nothing to do with this repo, it would be nice if we could go on in https://github.com/VLOGroup/imageutilities/issues/5 and close this issue here.

[raymond00000]

ok, so i will use 16.04 for OpenCV, which version you are using? I found that if I use OpenCV3.1, I have to choose a branch that support cuda 8.0?

You are using CUDA 8? or 7.5?

Many thanks for advice. I really have to make this works!! thanks.

[reini1305]

I'm using a self-compiled version of Opencv 3.2 and CUDA 8 on Ubuntu 16.04.

[raymond00000]

OK, for opencv 3.2,

I will refer to this guide: http://docs.opencv.org/trunk/d7/d9f/tutorial_linux_install.html

I will run this to cmake. cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. -D BUILD_SHARED_LIBS=ON

Do you foresee that above steps will lead a failure? Thank a lot.

[reini1305]

This should work, I also built it with default parameters.

[raymond00000]

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. -D BUILD_SHARED_LIBS=ON

better to add this too? -D BUILD_SHARED_LIBS=ON

thanks.

[reini1305]

Yes, if it is not enabled by default.

[raymond00000]

ok, i will try from scratch and let me know the result, thank a lot.

[raymond00000]

16.04.2-desktop-amd64.iso , you are using 16.04.2?

[reini1305]

14.04 but 16.04 will be fine

[raymond00000]

i am still installing new OS

my ccmake returned this, IU_USE_GUI is OFF ...

wait, let me update something, CUDA_SDK_ROOT_DIR..

[raymond00000]

export IMAGEUTILITIES_ROOT=~/dvs/dvs-reconstruction/imageutilities export CUDA_SDK_ROOT_DIR=/usr/local/cuda/samples export OpenCV_DIR=/usr/local/share/OpenCV

~/dvs/dvs-reconstruction/imageutilities/build$ ccmake . ccmake .

but i got this:

but i still got: CUDA_SDK_ROOT_DIR CUDA_SDK_ROOT_DIR-NOTFOUND

[reini1305]

Please set CUDA_SDK_ROOT_DIR directly within ccmake

[raymond00000]

yes, i now tried to set CUDA_SDK_ROOT_DIR directly , and IU_USE_GUI ON directly, hope I can build it, I am really appreciated for your advice! many thanks.

[raymond00000]

seems like i cannot change IU_USE_GUI ON as "generate" set it back to off..

[reini1305]

This means that either QT5 or OpenCV have not been found.
