After building all the projects successfully，I encounter a problem when runing the mono_kitti.

mpMapDrawer = new MapDrawer(mpMap, strSettingsFile);

After the program runs over this code, it exits directly.

What are the possible reasons？

Tried to build ORB_SLAM2 with Visual Studio 2015 , but ALL_BUILD of ORB_SLAM2.sln got an error in line 450 of ORBextractor.cc:
Error C2039: 'back_inserter': is not a member of 'std'
Error C3861: 'back_inserter': identifier not found

ORBextractor.cc need "iterator" with Visual Studio 2015(vc14).

#include <iterator>

I use opencv 3.2.0 and visual studio 2015(vc14). This project work correctly.

Hi, I build all successfully but...

I don't know what to do
Tanks

When I create an empty txt file, the code exited -1. Why?

1. Does that mean, when I run a brand new video, it will not work?
2. I thought building vocabulary of the scenery requires offline building database. If so, how does it work?

Hi,
I'm new to ORBSLAM2 and programming in general. I'm experiencing issue when trying to configure ORBSLAM24Windows on the Cmake-gui. I believe there is something wrong with the Pangolin directories.

The error said:

_CMake Error at C:/Users/Flamingo/Desktop/orbslam-windows/Thirdparty/Pangolin/build/src/PangolinConfig.cmake:26 (set_target_properties):
set_target_properties called with incorrect number of arguments.
Call Stack (most recent call first):
CMakeLists.txt:43 (find_package)

Configuring incomplete, errors occurred!_

Does anyone has a solution for this problem?

[I am using: OpenCV 3.4.5, Cmake 3.17.1, Visual Studio 15 2017]

I am trying with cmake to compile dbow2 with visual studio 2017(x64) and the configuration fails with the message
CMake Error at C:/Windows/System32/OpenCVModules.cmake:417 (message):
The imported target "opencv_core" references the file

 "C://x64/vc16/lib/opencv_core440d.lib"

but this file does not exist.
Any idea the reason of such problem?

Hi, I got some issues about the file "mono_tum" when rebuild the project "mono_tum". Here's the output I got when rebuild the file:

I use google and most of the answers are talking about someting like c++11 but I'm not sure about how to fix it.

I am trying to build the example of mono_tum; however, I am not understand the following steps.

Right click the mono_tum project and then click generate.
Download tum dataset sequence, for example freiburg2_desk
Right click the mono_tum project and then click Property->Config Property->Debug, input three parameters (Usage: ./mono_tum path_to_vocabulary path_to_settings path_to_sequence, the first can be ignored in windows)

I am using Visual Studio Express 2015, I do not have the option "generate" when I right click mono_tum project. Is it the same as "Build" ?
Moreover, I cannot find "Property->Config Property->Debug". Are there any corresponding location for setup.

Thanks for your help. This source is very helpful.

Side track suggestion: When I build "ORB_Slam2" I met the error "back_inserter': is not a member of 'std". I have added #include to that folder to complete the build

I'm using Opencv 3.2 on windows 10 with VS 2015.
Everything builds fine except for the main ORBSLAM2 library.
The error that Visual Studio throws is:
LINK : fatal error LNK1181: cannot open input file '..\lib\Release\ORB_SLAM2.lib'

The above directory is empty.
Any ideas on how to solve this issue?

Thanks!

In g2o/stuff/os_specific.c, the function int vasprintf() is defined within #ifdef WINDOWS, whereas the prototype definition at os_specific.h is within nested #ifdef WINDOWS and #ifndef _WINDOWS.

Is it an intended code?

Also, just to make sure,as documented in README.md, in step 5 of g2o, it says to add WINDOWS to prepossessor definitions. Is it WINDOWS and not _WINDOWS?

Thanks for your great work!
I manage to compile everything in the README.md but I don't know how to run some applications.Because I didn't compile and run a ubuntu project on windows with visual studio.
Could you please tell me how to do it or give me some advices about it in details?
Thank you very much?

Hello,

The project is successfully compiled but I got a problem while running the routines.
RGB-D sensor mode, for example, gives an error in generating Pangolin viewer. It seems to be an error of the window creation but no further information is given by the compiler. The snapshot is attached here.
