Qt5 dependency issues with Kinetic

[seanavery]

The first issue I was running into was that kinetic comes with opencv3 while the sdk requires opencv 2.4.*

What is the recommended ros version to use with this sdk?

I installed opencv 2.4.11 from source and I am not receiving the following error log:

Can you add the following command in CMakeLists.txt,

message( FATAL_ERROR ${OpenCV_DIR})

after find_package(OpenCV 2 REQUIRED core highgui) command.

Build again and share here the error log. @seanavery

[seanavery]

@jimcha21 Thanks for your response. Here is the new error log with the inserted command:

Okey.. remove the message() command and add before the find_package(OpenCV 2 REQUIRED core highgui) command, the following,

set(OpenCV_DIR "/directory/to/opencv/build/")

catkin_make again and let me know your results..

[seanavery]

nice, the set opencv dir command worked.

I am now getting the following error:

[seanavery]

I think it is just dropping the build files off in the wrong dir /opt/ros/kinetic/share/catkin/dji-guidance-ws/src

my build folder is pretty much empty and no cmake files

ls -la in /opt/ros/kinetic/share/catkin/dji-guidance-ws/src

[jimcha21]

Have you initialized a catkin workspace in the /home/sean/ directory , like /home/sean/catkin_ws/ ?

[seanavery]

Just tried in home/sean/__ but same problem.

You think it is an issue with permissions in build folder?

[jimcha21]

Yep probably.. You must create a catkin workspace in your home directory ( /home/sean/ ), as follows,

$ mkdir -p ~/catkin_ws/src/
$ cd ~/catkin_ws/
$ catkin_make

and then git clone this repo in ~/catkin_ws/src/ directory and execute cd ~/catkin_ws/ && catkin_make.

[seanavery]

I am getting this error now:

[seanavery]

Confused why it it wants /home/sean/dji-guidance-ws/src to be subdirectory of the source dir path.

I am thinking my Base, Source, Devel, and Install paths look correct.

[jimcha21]

In which directory have you cloned this repo ? Is it /home/sean/dji-guidance-ws/ or you cloned it in /home/sean/dji-guidance-ws/src/ ?

[seanavery]

I cloned into /home/sean/dji-guidance-ws/src/ .

But if I first catkin_make like above (with an empty /home/sean/dji-guidance-ws/src) before the cloning step --> it creates a CMakeLists.txt in the dji-guidance-ws/src folder. Should I keep this file?

[jimcha21]

Yes that's correct, don't delete that. The catkin_make works ok before cloning ? no errors ?

[seanavery]

yes no erors before cloning. Then cloning into ~/ws/src and mv CMakeLists.txt back into src. Then catkin_make once again from project root.

Using a similar process with catkin build I am getting the following error on second catkin build.
