Errors during compiling about depth_clustering

[RabahZeroukhi]

thanks for reply, I want to build using cmake .. and make -j4, it was configured well after editing Cmakelist.txt removing "find_package(eigen3 required)" and adding
"find_package(PkgConfig)
pkg_search_module(Eigen3 REQUIRED eigen3)",
because i had the problem which you mentioned (eigen 3 lib)

and then when i run " make -j4" it didn't compile the whole package

for you information, i have ubuntu 14.04 as OS and ROS indigo. thanks again.

Please install catkin_tools:

supo pip install catkin_tools

and run catkin build instead of catkin_make. It will probably produce either a proper build or a better error. Also, make sure that you have eigen3 library installed.

It looks like smth is wrong with your system. eigen3 should be found on a system with ROS indigo out of the box using find_package(Eigen3 REQUIRED) (make sure to spell Eigen3 exactly like here).

To check this, I have just spawned a new docker image with image: ros:indigo-perception and after following the installation steps everything builds as expected using cmake and make. You can also do it yourself if you have docker running on your system. Here are all commands:

Run the docker container:

sudo docker run -it ros:indigo-perception bash

Now from this container install the libraries missing out of the box:

apt update
apt install -y libqglviewer-dev freeglut3-dev

Now with libraries installed, clone and build the code:

mkdir -p catkin_ws/src && cd catkin_ws/src
git clone https://github.com/Photogrammetry-Robotics-Bonn/depth_clustering.git
cd depth_clustering && mkdir build && cd build
cmake ..
make -j4

This builds the code for me with no issues and proves that the code builds on a clean system. Therefore, I feel that there is smth strange going on on your side. I can't really tell you more, I guess...

Yes it works, thanks very much.

HI @niosus
I still meet the error while I use catkin build instead of catkin_make.

any help will be appreciated!

It can be solved by adding
FIND_PACKAGE(GTest)
and commenting
ADD_SUBDIRECTORY(/usr/src/gtest/ gtest)

anyone could refer to Stack Overflow to find the principle behind of this case.
