02:11 < rcurtin> uzipaz: I think it's been done before, but I don't remember what the exact details are since I have never done it myself

02:11 < rcurtin> I think that a lot of people do it with MinGW or MSYS

02:12 < rcurtin> https://mailman.cc.gatech.edu/pipermail/mlpack/2014-August/000488.html

02:12 < rcurtin> maybe that link is helpful...?

08:55 < vbas> any plan to include Gaussian process regression? it seems required optimization methods are already implemented

15:31 < rcurtin> vbas: no current plan to include GP regression, but contributions are always welcome

15:31 < rcurtin> I know he is not in here, but maybe he reads the IRC logs :)

15:34 < travis-ci> mlpack/mlpack#806 (master - 93eb34c : Ryan Curtin): The build passed.

17:47 < uzipaz> rcurtin: thanks for the reply, I am trying to install mlpack with cygwin on Win7 64, the c++ compilers in cygwin are upto date, but I am getting compilation errors when I do make install

17:48 < uzipaz> rcurtin: the first warning I get, /usr/include/armadillo_bits/compiler_setup.hpp:70:87: note: #pragma message: WARNING: Cygwin may have incomplete support for C++11 features; #pragma message ("WARNING: Cygwin may have incomplete support for C++11 features;")

17:49 < rcurtin> yeah, Armadillo tends to spit warnings whenever gcc or clang isn't used

17:49 < rcurtin> but do you actually have compilation errors somewhere?

17:49 < rcurtin> I have a meeting in 10 minutes, so my responses might be a bit slow, but I guess the first thing to do, if you can post the errors, is I'll take a look and figure out if the cygwin compiler is missing some C++11 support that mlpack needs or something

17:50 < rcurtin> and then see if maybe there is a way we can work around it, if that's the case

17:54 < uzipaz> rcurtin: Yes, there are compilation errors after the first warnings, but they are huge and I cannot post them here, You can see the full errors here http://pastebin.com/J2M1aN3R

17:56 < rcurtin> okay, thanks, let me take a look

17:59 < uzipaz> rcurtin: Thank you, appreciate it

18:23 < rcurtin> uzipaz: what compiler version?

18:26 < uzipaz> rcurtin: GNU compiler is 5.3.0-4, MinGW compiler is 5.3.0-1

18:29 < rcurtin> oh, sorry, I think this output is in the pastebin you gave, so I guess I didn't need to ask :)

18:30 < uzipaz> rcurtin: mingw64-i686-gcc-g++: GCC for Win64 toolchain (C++) 5.3.0-1, gcc-g++: GNU Compiler Collection (C++) 5.3.0-4

18:30 < uzipaz> rcurtin: I took this from Cygwin package installer

18:31 < rcurtin> okay, thanks for the info

18:31 < rcurtin> I am still in a meeting, but when it gets boring I steal a few minutes to look into this issue :)

18:31 < uzipaz> rcurtin: lol, thanks :D

19:34 < uzipaz> rcurtin: currently, I am trying to install mlpack with mingw/msys, but I need to install prerequisites such as boost and armadillo, I am building boost 1.60 from source with mingw, but I am getting lots and lots of warning msgs

19:35 < uzipaz> rcurtin: the gcc/g++ compiler in mingw that I downloaded and installed are version 4.9.3

19:42 < zoq> uzipaz: As long as there are only warnings it should be fine. You also get a bunch of warnings like 'unused parameter' on other platforms.

19:49 < rcurtin> uzipaz: what I managed to figure out was that it seems like posix_memalign() is not available on your system

19:49 < rcurtin> somewhere in armadillo_bits/compiler_setup.hpp, ARMA_HAVE_POSIX_MEMALIGN is being set even though posix_memalign() is not available

19:49 < rcurtin> and I am not sure why that is

19:49 < rcurtin> I didn't manage to dig any deeper to see if posix_memalign() really is available on your setup

19:50 < rcurtin> unfortunately I have to go for now, so I may not be able to look into it more for a little while

19:52 < sumedhghaisas> zoq: Hey marcus... any updates on MLPACK game competition?? I was wondering over the games to consider...

19:53 < uzipaz> rcurtin: Thanks for the help, I am trying to build mlpack with mingw/msys, ill let you know how that goes

19:54 < rcurtin> I sent a link yesterday to someone who did that, maybe you saw that email

19:54 < rcurtin> but that was mlpack 1.0.10 not mlpack 2.0.x

19:54 < rcurtin> so I think mlpack 2.0.0 and higher uses C++11 by default, which may make this difficult

19:57 < zoq> sumedhghais: I would prefer some browser game that we could play against each other, I'm open for recommendations :)

20:03 < zoq> something like worms or curve fever would be cool

20:03 < sumedhghaisas> zoq: yeah even I was thinking about the same... and it should not be a classic so no one gets natural advantage :P

20:16 < uzipaz> rcurtin: I am building armadillo 6.7 from source on Windows, I run cmake and its using visual studio compiler, Building for: Visual Studio 12 2013, is there a way to force it to use MinGW or is it somthing I sould not worry about what compiler it uses to build armadillo? Thanks

20:18 < uzipaz> zoq:

20:20 < zoq> uzipaz: Using 'CXX=/path/to/cygwin/g++.exe make' should work

20:20 < zoq> sumedhghais: A friend of mine recommended badeggsonline.com ... looks promising

20:21 < uzipaz> zoq: I've already added C:/MinGW/bin to my Path environment variable, if thats what you meant?

20:25 < zoq> uzipaz: hm, not really, if you build armadillo with msvs you should build mlpack also with msvs. So, I guess you could set CXX to the compiler you like to use to change that. Is there a reason to use cygwin instead of msvs?

20:25 < zoq> sumedhghais: I think we can't choose something that has a latency constraint ... just to be fair

20:27 < sumedhghaisas> zoq: ohh I like bad eggs... its like old tank game...

20:27 < sumedhghaisas> yeah thats right...

20:28 < sumedhghaisas> its 'tanks' the name of the old game

20:28 < uzipaz> zoq: I am on Win7 64, I was cygwin to build mlpack, but it doesnt work for reasons I dont understand yet... I am trying to use MinGW/msys to build mlpack

20:35 < zoq_> uzipaz: I see, this ARMA_HAVE_POSIX_MEMALIGN issue is definitely weird. I know from a fact that you can build mlpack on windows using MS Visual Studio 2015. You could even install all the necessary dependencies using nuget. That makes things a lot easier.

20:37 < zoq_> sumedhghais: I guess, we could also search for some ping pong game, but I guess it would be difficult to make it fair.

20:39 < zoq_> sumedhghais: Also since, we are all in different timezones, we could setup some 'sub' matches.

20:40 < zoq_> uzipaz: If you really like to build mlpack using cygwin I could try to replicate your setup.

20:58 < uzipaz> zoq: I just wanted to get mlpack to work in Windows, using specific compilers/tools doesn't matter as long as I can get mlpack working on Windows, thanks

21:02 < zoq> uzipaz: I guess in this case, your best option is to use msvs and probably nuget to install all the dependencies. The appveyor config: https://github.com/mlpack/mlpack/blob/master/.appveyor.yml is almost an step by step guide how to install mlpack on windows.

22:44 < uzipaz> zoq: I built from source LAPACK, OpenBLAS, armadillo, boost... when I get to build mlpack, I run cmake .. in the build folder... it says that openmp is not found

22:44 < uzipaz> rcurtin:

23:00 < rcurtin> uzipaz: that's okay, OpenMP is not required. so it's just a warning, right?

23:05 < uzipaz> rcurtin: please, take a look on the new errors, http://pastebin.com/C09g6zkv

23:09 < rcurtin> not at a computer right now... might be a few hours but I will look

23:09 < uzipaz> rcurtin: I think I didn't install boost correctly
