Cannot install v4r via apt-get

[danielzuegner]

I've followed the instructions of how to install the new v4r binary:

roscd squirrel_perception and then ./setup.bash

But sudo apt-get update now gives the following error: Failed to fetch http://153.97.4.193/building/ubuntu/dists/xenial/InRelease Could not connect to 153.97.4.193:80 (153.97.4.193), connection timed out

Also, pinging this address fails. Consequently, sudo apt-get install v4r yields

E: Unable to locate package v4r

I've compiled the latest v4r release from source. In catkin_make, this leads to errors that v4r/segmentation/dominant_plane_segmenter.hcannot be found.

Compiling v4r from the current Git sources lead to errors in catkin_make: 'DominantPlaneSegmenterParameter' is not a member of 'v4r'

Do you have any suggestion of how to solve this?

Thanks!

Daniel

It seems that our repo server is offline right now. @ipa-nhg Can you please check why it is offline?

@danielzuegner Unfortunately there are different versions of v4r available right now. We are in the process of getting solving this issue in the near future. Therefore I have to ask you from which git repo you pulled the v4r source? Thanks.

[danielzuegner]

@bajo Thank you for the quick response.

I pulled the v4r sources from this page. First I tried release 1.4.3, and then I did a plain 'git clone' of the repo.

@danielzuegner If the IPA server does not come online soon we can send you the debian package by email.

[danielzuegner]

@tpatten that would be great. I'll send you an email so that you have my address.

@danielzuegner That is the version we use within the STRANDS project and has not been updated because we did not want to risk any regressions during the final project phase. You can use V4R for the source or download the package from our buildserver https://rgit.acin.tuwien.ac.at/root/v4r/pipelines/475/builds Just click on the download artifacts button.

[ipa-nhg]

Sorry I didn't see this before. The IPA server is again available we had some network problems, sorry... but @danielzuegner are you using Ubuntu 16.04 (your sudo apt-get update said that you are looking for the Xenial distro) ? This may not work, we still didn't migrate the packages to kinetic

[danielzuegner]

Thank you all for your help. I was able to get v4r and squirrel_perception compiled on an Ubuntu 14.04 machine. However, the v4r classification as described in here seems to require a graphics card, which this machine doesn't have. My Ubuntu 16.04 computer does have a GPU, but I guess I'm out of luck there.

[tpatten]

Yes it is true. A graphics card is required in order to render the views of the CAD models. I am uploading a small set of models to my dropbox and will shortly send you a link so you can download.

Installation works now. Closing the issue.
