08:03 < daivik> Hi everyone, I'm having some trouble building mlpack from source. The build fails with the message "/usr/bin/ld: CMakeFiles/mlpack_preprocess_describe.dir/preprocess_describe_main.cundefined reference to symbol '_ZNSo9_M_insertIdEERSoT_@@GLIBCXX_3.4.9' ". I was wondering if someone has already faced this issue and could help me out with resolving t

11:20 < dungeon_master> As beginner who is wiling to contribute is it advisabe for me to download mlPack and buid it from source? Can't I just install it by `sudo apt-get install libmlpack-dev`
11:23 -!- sandy [9d31902c@gateway/web/freenode/ip.157.49.144.44] has joined #mlpack
11:25 < sandy> Hi everyone. I am Sanidhya and I am very much willing to learn and contribute to mlpack. I have really found it to be very interesting. I have downloaded mlpack and got myself familiarize with the library. I will be obliged if someone can help me to move forward with this.
11:50 < zoq> dungeon_master: If you like to contribute it would be advisable to build from source (you would need to open PR's and test your changes).
11:51 -!- jenkins-mlpack [~PircBotx@198-0-35-49-static.hfc.comcastbusiness.net] has joined #mlpack
11:52 < zoq> sandy: Hello there, the next step could be to go through the list of open issues and search for something that might be interesting to work on. You can also just go through the codebase and maybe you can find something that can be improved. Also, we are always open for new interesting methods.
11:55 -!- daivik [7d10a738@gateway/web/cgi-irc/kiwiirc.com/ip.125.16.167.56] has joined #mlpack
11:59 < dungeon_master> zoq: thanks! I'll build it from source. But as of now I've installed it by apt-get. Do you know how to uninstall it?
12:00 < zoq> dungeon_master: apt-get remove package
12:02 < dungeon_master> oh that was simple!! Sorry :P
12:02 < zoq> Here to help :)
12:03 < dungeon_master> :)
12:07 < daivik> @zoq - I asked earlier today about an issue I was (still am) facing with building mlpack from source. I've opened an issue as well (#1194). I'm getting a linking error which reads something like "error adding symbols. DSO missing from command line". Any clue on what the issue might be? I did some research and found #490 and #779 -- but those did n
12:07 < daivik> ot seem to help.
12:09 < zoq> daivik: Can you post the output of the configuration step (cmake ..)? It looks like it uses gcc instead og g++

12:19 < dungeon_master> zoq: shouldn't you think we should also add the unpacking step in (http://www.mlpack.org/docs/mlpack-git/doxygen.php?doc=build.html#build) as included in README of official repo https://github.com/mlpack/mlpack
12:21 < zoq> dungeon_master: hm, that might be an option, I guess on most systems you can just double click on the archive
12:22 < dungeon_master> Yup! but still it maybe useful in many unix based systems
12:22 < zoq> daivik: The output got cut off, I'm interested in the first step (compiler selection).
12:26 < daivik> Ah, I think you're right. The CXX compiler identification is GNU 5.4.0 -- same as the C compiler identification
12:27 < daivik> https://thepasteb.in/p/JZhpwYk807kCg -- >here's the complete output. sorry about earlier
12:28 < daivik> I guess I'll have to edit CMakeLists.txt now?
12:30 < zoq> daivik: Can you post the build/CMakeFiles/CMakeOutput.log file?
12:31 < zoq> Also do you have g++ installed?
12:32 < daivik> I do have g++ installed. Give me a minute and I'll upload the log file
12:39 < daivik> https://thepasteb.in/p/8qhOqRmWOWlF0 -- CMakeOutput.log ... sorry for the delay
12:42 < sandy> zoq: thanks a lot. Yeah! I am going through the list. I have found a few interesting ones on which I would like to work on. I'll post it here in case I have any issue. :)
12:44 < zoq> daivik: Thanks, can you run 'export CXX=g++' and 'export CC=gcc' before the cmake step and run again (make)?
12:44 < zoq> sandy: Sounds good.
12:45 < daivik> okay, I'll give that a try
12:45 < zoq> I'll have to step out, will be back later.
12:46 < daivik> Thanks a lot for your help!
13:25 < daivik> @zoq -- that worked beautifully. Thank you so much. I have posted the fix and closed my issue.
