ORB-SLAM3, make error

[xiaoyuamw]

Hi:
when i made the ORB-SLAM3, the following errors have occurred!
Anyone who can answer my problems? Thank you !

Hi @xiaoyuamw, I can guess the error comes from the LocalMapping file however you don't provide the error messages. Could you please post the full output you are getting when building ORB-SLAM3?

Regards.

These are the full output of error messages you wanted, i really hope that they are usefull for you. Thank you again!

Hi @xiaoyuamw, I cannot still see the error. I believe you are not copying all the ouput (maybe because your terminal removes old messages). Could you try to redirect all the output to a logfile and upload it? You can do it as it follows:

./build.sh &> log.txt

[xiaoyuamw]

Hi @jjgr3496, thank you fou your answer. I have made again by your method, this time you can see the full uotput of error messages. Thank you again!
log.txt

[jj-gomez]

Hi @xiaoyuamw, thanks for updating the log. I have finally been able to spot the errors:

• At Map.h, in line 140, you should put the name space before list and string (the line should end up looking like this: void printReprojectionError(std::list<KeyFrame*> &lpLocalWindowKFs, KeyFrame* mpCurrentKF, std::string &name, std::string &name_folder);). This error seems to pop up depending of the version of your compiler.

• At MLPnPsolver.cpp, we call the method Eigen::SparseMatrix<double>.setIdentity(), however your compiler seems like cannot find it. Please, check your Eigen version (remember we require a version grater than 3.1.1).

• Finally, the last error looks like a problem when finding the file openssl/md5.h. You should first install in your system the openssl library (https://cloudwafer.com/blog/installing-openssl-on-ubuntu-16-04-18-04/).

These are all the errors I can find from your log. If you keep finding some issues building, paste me again the log!

Regards.

Hi @jjgr3496, i have met such an error this time, maybe you can help me to solve it. Thank you again!

Hi @xiaoyuamw, could you please upload again the build log file with the new error?

Hi @jjgr3496, i have uploaded the full output of the build log file, maybe you can find out where the errors happened. Thank you again!

[jj-gomez]

Hi again @xiaoyuamw, after reading carefully the log file, I finally found the error (I had to translate from Chinese to English to discover the error :P). It seems that you don have installed the lboost_serialization so the compilation fails. Please, try to install that library and compile again.

[xiaoyuamw]

Hi @jjgr3496, i have run the ORB-SLAM3 successfully, and i will take a further study of this greatful project made by you and your team, thanks very much again!

[kanishkanarch]

@jjgr3496 Hello Juan, I admire your work in SLAM and have used your ORB-SLAM3 package in my research earlier.
Earlier before when I compiled the repository, I solved the small errors myself, but I don't know how to solve errors this time. Can you please check my log file and help me identify what can be done?
Thanks
This is the log file of ./build.sh

[kanishkanarch]

Update:
I successfully compiled the project. The error was coming from a broken OpenSSL version that I installed apart from the version that comes with Ubuntu 18.04.
Thank you

Hi again @xiaoyuamw, after reading carefully the log file, I finally found the error (I had to translate from Chinese to English to discover the error :P). It seems that you don have installed the lboost_serialization so the compilation fails. Please, try to install that library and compile again.

Thank you. I meet the same issue. Through installed the boost, I successfully compiled the project. How to installed the boost? You could watch my blog.
