05:18 < piyush_chaudhari> I am trying to install Armadillo C++ Linear Algebra Library for which I have to install following package(as per given in documentation) name : ARPACK, for building mlpack from source, I am trying to install ARPACK as per given instruction in README file but throwing error (shown below) :

05:18 < piyush_chaudhari> Making lib in /home/piyush/ARPACK/UTIL /bin/sh: 6: /bin/make: not found

05:18 < piyush_chaudhari> Making lib in /home/piyush/ARPACK/SRC /bin/sh: 6: /bin/make: not found

05:19 < piyush_chaudhari> Makefile:57: recipe for target 'arpacklib' failed

05:19 < piyush_chaudhari> need help, I tried hard but can't make it

06:04 < jenkins-mlpack2> Yippee, build fixed!

06:04 < jenkins-mlpack2> Project docker ensmallen nightly build build #77: FIXED in 49 min: http://ci.mlpack.org/job/docker%20ensmallen%20nightly%20build/77/

14:57 < rcurtin> piyush_chaudhari: what have you tried to fix the issue? it looks like 'make' is not installed

14:58 < rcurtin> also, why not just install via your system's package manager?

16:58 < piyush_chaudhari> Okay, I will try via system's package manger.

17:07 < piyush_chaudhari> can armadillo be installed using system's package manager?

17:08 < zoq> piyush_chaudhari: Yes, are you on debian/ubuntu?

17:15 < piyush_chaudhari> yeah in ubuntu 16.04

17:16 < piyush_chaudhari> I recently install synaptic package manager

17:16 < zoq> So 'apt-get install libarmadillo-dev' should work.

17:23 < piyush_chaudhari> yeah working on it....

17:24 < piyush_chaudhari> But what about dependencies given in documentation?

17:25 < piyush_chaudhari> That according to documentation : On Linux-based systems, the following libraries are recommended

17:25 < piyush_chaudhari> to be present: OpenBLAS, LAPACK, SuperLU and ARPACK.

17:25 < zoq> piyush_chaudhari: SInce you are on ubuntu you can follow: http://mlpack.org/doc/mlpack-3.2.1/doxygen/build.html

17:27 < piyush_chaudhari> Yeah I am following same page of documentation.....

17:28 < zoq> So as mentioned on the page "In Ubuntu and Debian, you can get all of these dependencies through apt:"

17:28 < zoq> the command should install all the necessary dependencies

17:29 < zoq> like openblas will be installed as a dependency of armadillo if you install libarmadillo-dev

17:31 < piyush_chaudhari> Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) ........is what I am getting even after killing the process

17:32 < piyush_chaudhari> when I execute apt-get install libarmadillo-dev

17:33 < zoq> is synaptic still open?

17:34 < piyush_chaudhari> yes

17:34 < piyush_chaudhari> I killed all the process ongoing and know it is showing : Unable to locate package libarmadillo-dev

17:36 < zoq> apt-get update might help, not sure is this the first time you run apt-get?

17:38 < piyush_chaudhari> no zoq.... frequently I use

17:39 < zoq> strange

17:40 < piyush_chaudhari> for armadillo I have downloaded the package(tar) file from site and was following the steps for installation as per givent in README file

17:40 < zoq> I guess you could use apt-cache search, to search for the package

17:40 < zoq> I see, but as rcurtin already pointed out it would be way easier to install all the dependencies through the package manager

17:41 < piyush_chaudhari> which one ?

17:41 < zoq> armadillo

17:41 < piyush_chaudhari> synaptic / aptitude ?

17:41 < zoq> apt-get

17:42 < zoq> they source the same package, so you could use synaptic if you like

17:43 < piyush_chaudhari> when I use apt-get it says Unable to locate package libarmadillo-dev but obvious?

17:44 < zoq> have you used apt-cache search as I mentioned above to search for the armadillo package?

17:45 < piyush_chaudhari> working on it....

17:49 < piyush_chaudhari> after executing -> apt-cache search libarmadillo-dev it shows nothing

17:49 < zoq> just search for armadillo

17:50 < piyush_chaudhari> same nothing it shows

17:52 < zoq> same if you search for blas?

17:52 < piyush_chaudhari> I am clueless why such strange behaviour I see...like from last 11 hours trying to figure out

17:53 < piyush_chaudhari> no able to search blas

17:53 < piyush_chaudhari> giving dependency packages info

17:53 < piyush_chaudhari> no, able to search blas.

17:55 < zoq> maybe you are missing some entries in the sources.list file, can you check that file?

18:02 < piyush_chaudhari> yeah I guess haven't configured it....

18:43 < rcurtin> have you run `apt-get update`?

18:45 < piyush_chaudhari> Thank you rcurtin and zoq for helping me, recently I have successfully installed armadillo from synaptic.....

18:46 < piyush_chaudhari> but as I see ensmallen is not present in synaptic...

19:16 < zoq> If you build mlpack by source it's part of the build process, if you install mlpack via the package manager it's already included as well.

19:18 < piyush_chaudhari> okay.....

19:18 < piyush_chaudhari> as i see version are not updated in package manager

21:00 < RyanCurtinGitter> test message via Gitter

21:04 < RyanCurtinGitter> okay, so, let's hope this lasts, but the mlpack/mlpack Gitter room is now connected to the #mlpack:matrix.org channel, which is also connected to the mlpack IRC channel :)

21:04 < RyanCurtinGitter> there can sometimes be semi-significant lag between the three rooms, but the message does seem to get there eventually...

21:07 < piyush_chaudhari> alright
