sumitOh cool BlackBurn :) :) , just returned from the classes and read your reply :) I shall get it done in an hour or so and get right back to you :) , thanks..Yet I feel I should grasp more about shogun toolbox b4 I develope codes compatible with Shogun :)08:34

n4nd0wiking: so make in the tests dir run smooth yesterday13:28
n4nd0the tests are the ones under tests/integration right?13:29
wikingnoup tests are under tests/unit13:31
n4nd0wiking: aham I see13:31
n4nd0so they have to be built apart too?13:32
wikingwell if u run make in tests/unit13:32
wikingthen they'll be built13:32
n4nd0I run yesterday make under tests I think13:33
n4nd0mmm no that cannot be13:33
wikingtry to run a make under tests/unit13:33
wikingyou should see some info about the unit tests if everything is ok13:33
n4nd0yeah13:38
n4nd0make is failing under tests/unit now for some reason13:39
wikingok check the reason13:39
n4nd0a method is not found in CDataGenerator13:40
wikingmmmm interesting13:40
n4nd0a method that actually seems to be there13:41
n4nd0generate_gaussians13:41
wikingmmm maybe it's because i think that func needs some lib13:41
wikinglike lapack or something?13:41
n4nd0right13:42
n4nd0probably I don't have it installed here13:42
n4nd0checking configure13:42
n4nd0wiking: I think that lapack is not detected by configure13:49
n4nd0can you check one thing a moment please?13:49
n4nd0I have seen that in the configure script there are checks for -llapack13:49
n4nd0however here whereis llapack doesn't find anything13:50
n4nd0I have to use whereis liblapack13:50
n4nd0it might be a naming thing?13:50
wikingmmm13:58
wikingwell i guess it's more like it doesn't have the right library path to find your lapack13:59
n4nd0nvm14:00
n4nd0I checked configure.log, cblas.h is not found14:00
n4nd0installing atm14:00
n4nd0 /usr/bin/ld: libgmock.a(gtest-all.o): undefined reference to symbol 'pthread_key_delete@@GLIBC_2.2.5'14:16
n4nd0 /usr/bin/ld: note: 'pthread_key_delete@@GLIBC_2.2.5' is defined in DSO /usr/lib/libpthread.so.0 so try adding it to the linker command line14:16
wikingmmmm14:16
wikingi wonder why you dont have -pthread or -lpthread added to your linker flags14:16
n4nd0-pthread is included14:17
n4nd0the line that is just before the undefined reference message14:18
n4nd0c++ -I../../src -fPIC  -g -Wall -Werror-implicit-function-declaration -Wno-unused-parameter -Wformat -Wformat-security -Wparentheses -Wshadow -Wno-deprecated -O0 -pthread -I/usr/include -I/usr/src/gmock/include -DSWIG_TYPE_TABLE=shogun -DSHOGUN -DLINUX -DUSE_BOOL -DUSE_CHAR -DUSE_UINT8 -DUSE_UINT16 -DUSE_INT32 -DUSE_INT64 -DUSE_UINT64 -DUSE_FLOAT32 -DUSE_FLOAT64 -DHAVE_POWL -DHAVE_LGAMMAL -DHAVE_SQRTL -DHAVE_LOG2 -DHAVE_PTHREAD -DHAVE_14:18
wikingmmm14:18
n4nd0pthread is in there ^14:18
wikingcan u replace -pthread with -lpthread14:18
wikingi mean just prepend the thing with l ;P14:18
n4nd0hehe I just copied the line and added the l14:20
n4nd0no error then14:20
wikingmmm this needs to be fixed14:22
wikingi just wonder how can we fix this14:22
n4nd0where are those flags set?14:22
wikingi guess the flag -pthread and -lpthread has changed14:22
wikingin one gcc version14:23
wikingwhat's your gcc version?14:23
n4nd04.7.214:23
wikingmmmm14:23
wikinginteresting14:23
n4nd0why?14:23
wikingso it's kind of like the latest14:23
wikingbecause i thought that the older gcc had -lpthread flag14:24
wikingand the newer ones switched to -pthread14:24
n4nd0I don't really understand why it fails with -pthread14:25
n4nd0I thought they were basically quite the same14:26
wikingyeah me too14:26
wikingi thought that it's just a version difference14:27
wikingin gcc14:27
wiking '-lpthread' means 'link with a library called pthread'.14:28
wiking        '-pthread' means 'do whatever you have to do to compile code that14:28
wikingcomplies with the pthreads standard so that it works'.14:28
wiking        '-lpthread' should not be used if '-pthread' is available unless you14:28
wikinghave some very specific reason.14:28
wikingmmm14:28
wikinginteresting14:28
wikingbut obviously -pthread doesn't work for ya14:28
wiking:>14:28
n4nd0hehe yeah it seems so14:28
wikingso it did not do everything to get your code compiled14:28
wiking:)14:28
n4nd0hehe14:29
n4nd0this is weird14:31
n4nd0I am checking my gcc specs14:31
n4nd0and I think it actually links with -lpthread14:31

n4nd0blackburn: ey16:03
blackburnn4nd0: hey16:03
n4nd0blackburn: have you seen this pthread issue ^?16:04
blackburnno, what is it?16:04
n4nd0so16:04
n4nd0-pthread gives me a compile error that is solved when I use -lpthread16:05
n4nd0but it seems from gcc that -pthread is actually also linking with -lpthread16:05
blackburninteresting16:06
blackburndoes that happen only on your machine?16:06
n4nd0no idea16:09
n4nd0I guess wiking could compile without the erro16:09
n4nd0anyhow, gtg now maybe I can check it with him later16:10
n4nd0see you16:10

heiko1sonney2k, blackburn, around?17:56
blackburnheiko1: yes17:57
heiko1already idea for gsoc projects?17:57
heiko1blackburn, I might have a nice one, and thinking of others, but wondering what you guys have in mind17:58
blackburnheiko1: well just suggest :)17:59
blackburnheiko1: I would like to have one dim reduction student17:59
blackburnheiko1: soeren asked andreas ziehe for ICA stuff18:00
blackburnheiko1: I will try to convince igor carron to lead something about compressive sensing18:00
heiko1ICA nice :)18:04
heiko1I would like to do something on computing Gaussian likelihoods for large models18:04
heiko1which involves iterative linear solvers, graph colourings, and sparse matrices18:05
heiko1blackburn, and would allow MCMC on those large models18:06
heiko1which is currently very very hard18:06
heiko1so a truly large-scale project :)18:06
heiko1I know a few people who could help me mentoring it18:06
blackburnheiko1: go ahead then :)18:08
heiko1cool, do we already have an ideas page?18:08
blackburnheiko1: would be nice if you describe it18:08

blackburnI hope we will get enough slots :D18:09
blackburnah wait18:09
blackburnI hope we will get accepted18:09
blackburnah wait18:09

@sonney2kheiko1, I was hoping that you would rather mentor this year21:09
@sonney2kheiko1, you can do your fun project anyways21:09
heiko1sonney2k, I was talking about mentoring this one21:10
blackburnsonney2k: hmm I realized I don't get whether heiko1 wants to mentor it or be a student21:10
blackburn:D21:10
heiko1I am not a student in the summer :)21:10
blackburnI thought so!21:10
heiko1sonney2k, dont worry :)21:11
blackburnright - you told that yesterday heiko121:11
heiko1sonney2k, two more mentors this year21:11
blackburnit is difficult to live without brain..21:11
blackburnheiko1: or three21:11
heiko1what? :)21:13
blackburnheiko1: you mean two = you and me?21:13
blackburnor?21:13
heiko1oh21:13
heiko1yes21:13
blackburnthen count wiking - he could mentor too21:13
heiko1blackburn, ok :) but with you and me I am sure21:14
blackburnparteigenosse wiking is reliable!21:15
blackburn:D21:15
heiko1haha :)21:15
blackburnheiko1: I tried to learn a bit of deutsch from 1992 book - they say I shouldn't call people genosse anymore but it is ok still21:16
