@sakurazhu
It's a bug of opencv2.10, you can follow this link to modifiy and rebuild opencv. http://code.opencv.org/issues/3983

If you don't want to build opencv from source code, just type:
sudo apt-get install libcv-dev libcvaux-dev libhighgui-dev libopencv-dev

It works for me always.

[sakurazhu]

i have tried your method,but the error happened again and one more error happened

i have tried gcc 4.6 and gcc 4.9 ,however ,the error still there @joyousrabbit @poine @raulmur

[joyousrabbit]

@sakurazhu
Did you modifified the source code as explained by the forum?

I suggest you try the following steps:

1. supprime the downloaded opencv2.10;
2. sudo apt-get install libcv-dev libcvaux-dev libhighgui-dev libopencv-dev
3. ./build.sh the ORB-slam

sakura@ubuntu:~/ORB_SLAM2$

[joyousrabbit]

I'm glad that it helps. For the new error, you should be very close because you already got the .o files. So I guess that it's a link problem.

Try do it again, take care of all the parameters behind cmake and make.

[joyousrabbit]

Which commands did you use? In which path?
Could you show me the history like sakura@ubuntu:~/ORB_SLAM2$XXX XXXXXX which you typed?

[sakurazhu]

@joyousrabbit i used the following commands:

sakura@ubuntu:~ORB_SLAM2 $ chmod +x build.sh
sakura@ubuntu:~ORB_SLAM2 $ ./build.sh

[joyousrabbit]

@sakurazhu
So was the executalble in folder example/mono_tum/ generated?
If yes, it's ok, just run it.
if no, I guess you have to reinstall eigen3.

[joyousrabbit]

@sakurazhu
I think it's a g++ bug.
Could you show me your g++ --version, gcc --version, and your system version?

[sakurazhu]

@joyousrabbit yes the gcc version is 4.9.2 (Ubuntu 4.9.2-0ubuntu1~12.04) .

OK, I konw.
Please use the command ' ./build.sh > build.txt ' and send the generated build.txt to my email [email protected] . We will see what happened.

[joyousrabbit]

@sakurazhu
According to your build information, your Eigen3 version is 3.0.5, at least version 3.1.0 is required.

[sakurazhu]

i have tried to use eigen3.2.8, but it did not work,the same problems appeared again. @joyousrabbit
Anyway,thank you very much for your unselfish help .

@Matrixio

Seems a bug. Could you try this fix: https://github.com/ethz-asl/ethzasl_msf/pull/111/files , as showing, replace all double_t with double.

[liuyangyl]

I have met the same problem with @Matrixio , and I want to try the solution of @joyousrabbit , but I cannot find the files msf_state_inl.h and msf_state.h . How could I find them ? Or maybe I did not have them?

[sakurazhu]

yeh ,i can not find the msf_state_inl.h and msf_state.h files either.

[amarant]

To correct it change here SparseMatrix::Index to int. It's a dirty fix, bit it works.

[Matrixio]

I solved the problem.
change "make -j" to "make -j1",
my ubuntu run on a virtual machine.

best regards

Hello everyone,

I would like to run ORB-SLAM2 on Linux OS (Ubuntu 16.06 Xenial) with CPU intel Corei7 , 2.2 GHZ and I have tried to install the prerequisities, which were written in the README.md file on github.com. But the problem is I have faced several errors during building ORB_SLAM2 and compiling ORB_SLAM2 Examples for mono_tum.cc and mono_kitti.cc. It would be so kind if you can help me in this way because the type of error is somehow the same as above but the solution did not work for it.

[amarant]

Have you tried the fix in my comment ?

[ramtinkr]

@amarant Thanks for your response.
Yes, I have tried the fix by replacing {SparseMatrix::Index} to {int}. But the same error showed up.

[liuyangyl]

Matrix solved the problem.
change "make -j" to "make -j1",
his ubuntu run on a virtual machine.

Thanks @liuyangyl. I have tried "make -j1" but the same error showed up. It have not built more than 3%. It think it would be a better idea to change my Ubuntu version from 16.04 to 14.04 like @sakurazhu.

[sakurazhu]

maybe there is something wrong with your Pangolin . when i met the problem i delected all the code about Openni* in Pangolin--src --CMakeLists . And then used make -j4 to make it successfully. Hope it works for you.

Thanks for your hint @sakurazhu . I have rebuilt my Pangolin successfully with make -j4 as you mentioned but unfortunately in rebuilding the ORB_SLAM2 I faced the same error. Today I am changing the version of my Ubuntu to 14.04 and try to rebuild ORB there.

[ramtinkr]

Hi friends,

Today I changed the version of my Ubuntu to 14.04.04 LTS (Trusty Tahr) and I have built ORB-SLAM2 100 % successfully but at the end I got an error (CV_LOAD_IMAGE_UNCHANGED) of .CC Files of Examples { mono_tum.cc, mono_kitti.cc, rgbd_tum.cc, stereo_kitti.cc }. While compiling these file like mono_tum.cc, I also faced several errors related to CV_LOAD_IMAGE_UNCHANGED, Monotonic_clock, t1 & t2. Building Pangolin & Eigen were successful but after ORB_SLAM2 was build I found the built files locked, does anyone know how can I remove those errors and how to unlock the ORB "build" and "lib" Files?

Thanks a lot

[ramtinkr]

I solved the error of CV_LOAD_IMAGE_UNCHANGED by adding #include highgui.h. My only problem at the moment is "std::chrono::monotonic_clock", although I have the header #include , it does not work. I listed my headers in a screen shot as below.

[shishiteng]

Thank you @amarant ,I modified "SparseMatrix::Index" to "int",now it works.

[MartinXM]

I'm using Ubuntu 16.04 and met the same problem with @ramtinkr . The following trick works for me.
http://stackoverflow.com/questions/38647114/orb-slam-installation-on-ubuntu-xenial-16-04

[xuyongzhi]

This works for me too. @Matrixio Thank you!
But I am still wandering are there any other problems while using ubuntu16.04 with ORB_SLAM2. For instance the ROS version has to be Kinetic instead of indigo. Do you know if ROS kinetic works for ORB_SLAM2?

[cambazz]

@MartinXm how did you install the ubuntu 14 package in ubuntu 16?

[cambazz]

The build was stopped at the same place, I tinkered for a while and installed libeigen2-dev and libeigen3-dev tru apt-get on ubuntu 16 xenial with roskinetic, and i believe i have a succesful build.
