build error

[hshsjkjy]

While running step 11/17 : RUN /bin/bash -c 'source /opt/ros/melodic/setup.bash && catkin build' I met such a problem and I have already installed the Eigen

How can I solve this bug？

Hi,

thanks for the interest in my work and the usage of the new docker container :)

Since the container does install libeigen there must be some changes in the links of eigen. In this issue https://stackoverflow.com/questions/23284473/fatal-error-eigen-dense-no-such-file-or-directory#25537967 there was a similar problem. I will need to debug it further, i will give it a spin this weekend :)

Thanks for your patience! Best, Johannes

Thank you for your reply. I did create symlinks to solve the problem, but it doesn`t work. I wonder if I should re-install the libeigen. Looking forward to your solution.

Hi:)

did you do the link on your machine or in the Dockerfile (that is building the docker image). please consider that you are building a docker image, so what you have installed (and linked) on your machine ist not relevant for the container (which is the beauty of it :) since you have an isolated system then) what you can do is add a RUN statement in the Dockerfile, that does the link to eigen and rebuild it :)

Thanks for your effort! Best Johannes

Thanks for reminding me of that, now it works well by creating symlinks in the Dockerfile. Sorry to disturb you for such a stupid bug, hope you have a good day:)

No worries, there is no such thing as stupid bugs ;) I am happy that you are interested in my code :)! I would be happy if you would add it to the project as your contribution. Fork the repo make branch and file a pull request:) in that way your contrib is documented ;)

Best, Johannes
