08:02 < Atharva> zoq: I used data::Save("vaeModel.xml", "vaeModel", vaeModel, false); But it gives an extremely verbose error message followed by collect2: error: ld returned 1 exit status.
08:02 < Atharva> Do you know of a reason this might happen, I just cannot figure out what the error message says, it's too long.
09:34 -!- lozhnikov [] has quit [Quit: ZNC 1.7.0 -]

15:07 < wenhao> lozhnikov, zoq, rcurtin: Hey guys! As I am traveling to Europe next week (from around 11th to 21th), I probably wouldn't have much time to work on mlpack during the trip. I will work extra time in the following weeks and I think I will be able to keep up my schedule. Is that alright?

15:59 < ShikharJ> zoq: The test output seems largely unaffected for the latest changes, I'll get to figuring out why the test is failing. Might be because of the way we're doing resets and initializations.
17:52 -!- witness_ [uid10044@gateway/web/] has joined #mlpack
18:45 < lozhnikov> wenhao: As for me, it's ok provided that you are on schedule. So, just don't disappear and keep up the schedule. Have a nice trip!:)
18:49 < ShikharJ> zoq: Ah, I found the error within the test-case implementation. Pushing a fix in an hour.
19:56 < rcurtin> wenhao: no issue from my side, have a great trip! :)
19:56 < rcurtin> if you go somewhere cool, feel free to share a picture :)
20:02 < Atharva> rcurtin: I posted a doubt to zoq about 12 hours back. He seems to be away for the weekend. Do you know why that might happen?
20:03 < rcurtin> if it ends with "ld returned 1 exit status" it sounds like the linker didn't properly link
20:03 < rcurtin> are you writing some standalone C++ program and compiling with gcc? if so, my first guess is you need to link against boost serialization (add -lboost_serialization)
20:03 < rcurtin> you can take a look through the error message and look at the names of the unresolved symbols to try and guess the library that needs to be linked
20:04 < Atharva> Ohh, I didn't do that.
20:04 < rcurtin> my guess is it's lots of stuff like 'boost::serialization::...' that can't be linked
20:05 < Atharva> It worked, thanks! I will keep this in mind when I get such errors the next time.
20:05 < Atharva> It was the linking issue.
20:09 < rcurtin> sure, happy to help :)
