Error while 'making' without ROS dependency (Eigen::Map<const g2o::Vector7d> v(m);)

[9friday]

I have a 64-bit laptop with Ubuntu 17.10. I am trying to run LSD-SLAM without the ROS dependencies. I have found three repos which contain LSD-SLAM without the ROS dependency. They are all modified versions of the original LSD-SLAM. ROS is just used for IO so the rest of the code should be pretty much the same. But on building them with cmake and then executing 'sudo make', I get a common error across all three repos.

These are the links to the repos:

1. https://github.com/aivijay/lsd_slam_noros
2. https://github.com/mp3guy/lsd_slam
3. https://github.com/jserv/lsd_slam

While 2 and 3 give the exact same error, 1 is a bit different:

But even this has the error related to this line(link takes you to g2oTypeSim3Sophus.h, the file that contains this line of code) : Eigen::Map<const g2o::Vector7d> v(m);

I would be really grateful if you guys could help me out or just point me in the right direction.

Than You :+1:

[OAkyildiz]

This is untested as of now because I am running into further build problems but either add #include "g2o/types/sim3/sim3.h"

or in utils/SophusUtils.h:40, uncomment // typedef Sophus::Vector7d Vector7;

It is most likely that you will run into other building porblems causing from version changes (i.e. g2o updated their Solvers to not own the pointers and switched to unique_ptr instead)

@OAkyildiz , thanks for the advice. I tried that but I am getting the same error:

I tried the changes on the https://github.com/jserv/lsd_slam repo.

Thanks for helping. I will keep trying to solve this.

Cheers :+1:

Were you able to solve this?

No, i haven't been able to solve this. What are the steps you took for installing this?

g2oTypeSim3Sophus.h line 96

change to

g2oTypeSim3Sophus.h line 96

I think that maybe a misstype of Sophus::Vector7d
