dv::dvsdk target not found

[LaiKefan1]

Hello! I have a problem while building the project.
I have installed dv-runtime on my computer, but when I run "catkin build" to build the project, an error outcomes as follows:

“
CMake Error at CMakeLists.txt:52 (add_library):
Target "dv_ros_lib" links to target "dv::dvsdk" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?

CMake Error at CMakeLists.txt:59 (add_executable):
Target "dv_ros_node" links to target "dv::dvsdk" but the target was not
found. Perhaps a find_package() call is missing for an IMPORTED target, or
an ALIAS target is missing?
”

Is CMakeLists wrong? Or how can I install this dv::dvsdk and let the CMakeLists know?
Thanks!

I find out that changing "dv::dvsdk" into "dv::sdk" can solve this problem!
But there happened to be another problem, which says in */dv_ros/accumulator/accumulator.cc:115:9: error: ‘struct dv::Frame’ has no member named ‘convertTo’
115 | frame.convertTo(corrected_frame_, CV_8U, scale_factor, shift_factor);
Does anyone have the same problem?

I also encountered the same problem, may I ask you to solve it, do you need to change to the old version of dv-runtime?

I face this problem too

I change the version of dv-runtime and installed 1.4.5, but the problem has not been solved.

You can try to change
frame.convertTo(corrected_frame_, CV_8U, scale_factor, shift_factor);
into
frame.image.convertTo(corrected_frame_, CV_8U, scale_factor, shift_factor);

Thank you so much for your response

Sorry for the late reply. Have you solved this problem? This may be caused by the update of dv-runtime.

Thank you for your attention. This problem is solved but there is another problem with dv-ros. Because it needs dv-runtime and dv-processing for building. Dv-runtime and Dv-processing should be installed while both of them need gcc-10. When I install gcc10 I faced this error:

/opt/ros/melodic/include/ros/serialization.h:335:82: error: no class template named ‘rebind’ in ‘class std::allocator<celex5_msgs::Event_<std::allocator > >’
335 | typedef std::vector<T, typename ContainerAllocator::template rebind::other> VecType;

/opt/ros/melodic/include/ros/serialization.h:336:38: error: no class template named ‘rebind’ in ‘class std::allocator<celex5_msgs::Event_<std::allocator > >’

std::allocator::rebind was deprecated in C++17, removed in C++20.
I would appreciate it if you please check this issue.

dv-runtime-1.2.5
need gcc >= 7.0, no need gcc >= 10.0
I success.

uninstall dv-runtime-dev

apt list --installed | grep -i dv-runtime-dev
sudo apt remove dv-runtime-dev
sudo apt-get purge dv-runtime-dev

download dv-runtime-1.2.5

https://gitlab.com/inivation/dv/dv-runtime/-/tree/1.2.5?ref_type=tags

build dv-runtime-1.2.5

cd dv-runtime-1.2.5
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
make -j8
sudo make install

error

Thank you so much for your response and sharing your information.
How did you install dv-processing?
As I know dv-processing need the gcc=>10 too

I don't know. When I uninstalled the dv-runtime that comes with the system and installed the dv-runtime-1.2.5 source code, the dv_ros was compiled successfully.

In my Ubuntu 18.04,

apt-cache search dv-processing
# -> dv-processing - Generic algorithms for event cameras (C++ headers).
# dv-processing-python - Generic algorithms for event cameras (Python bindings).
# dv-processing-utilities - Generic algorithms for event cameras (CLI utilities).

apt list --installed | grep -i dv-processing
# -> dv-processing-utilities/bionic,now 1.7.9-1~bionic amd64

apt-cache policy dv-processing-utilities                                   ─╯

I noticed that this version was three years ago, but dv-runtime has been updated. I compared the version and found that 1.4.6 should be used, and it is dv::dvsdk. I hope my reply can solve your problem
