CaBawiking: you there?19:01
@HeikoSCaBa: he is probably asleep19:26
@HeikoSmiddle of the night over there ;)19:27
CaBaHeikoS: well... one should actually compute some irclog stats on that ;)19:27
@HeikoShehe indeed19:27
CaBaHeikoS: in how far "in the middle of the night" correlates with "asleep" for wiking  ;)19:27
CaBaHeikoS: https://github.com/shogun-toolbox/shogun/issues/3459 do you know anything about this?19:29
CaBaHeikoS: i can't get my kernel to compile when i set the normalizer inside the kernel upon construction19:29
@HeikoSCaBa: it doesnt a lot I guess.....19:29
CaBaHeikoS: seems to be some include loop dependency or something :P19:29
@HeikoSinverse correlation19:29
@HeikoSchecking19:29
CaBaHeikoS: i just found this and it seems to be the same problem...19:29
CaBaHeikoS: that's not my bug19:30
@HeikoSphew no19:30
@HeikoSbesser82_:  might know something19:30
@HeikoSI would have to reproduce this locally19:30
CaBak, i'll see if i catch him19:30
@HeikoSwhat happening on your machine?19:30
CaBawell if i do set_normalizer(new CSqrt...()) in my kernel it won't compile, with that error from the bug19:32
CaBaif i construct my kernel first and then use CKernel::set_normalizer() from "outside" it works fine19:32
CaBai don't know... seems something forward related, since the kernel and the normalizer header include eachother...19:32
CaBa/Users/lk/RESEARCH/external/shogun-release/include/shogun/kernel/Kernel.h:213:21: error: invalid use of incomplete type 'class shogun::CKernelNormalizer' return normalizer->normalize(compute(idx_a, idx_b), idx_a, idx_b);19:38
CaBathat's what i get with gcc 6.319:38
CaBaHeikoS: ok, my bad. this has nothing to do with set_normalizer() of course19:42
CaBaHeikoS: if i simply include 'shogun/kernel/normalizer/SqrtDiagKernelNormalizer.h' in the compilation unit of my custom kernel i get this error19:43
@HeikoSok19:43
@HeikoSso some forward declaration error based on a certain include setup?19:43
CaBai guess so19:43
@HeikoSis that covered in any of our examples?19:43
@HeikoSI wonder whether it is part of the testing suite19:44
CaBaHeikoS: well the guy who tried to build on debian in the bugreport apparently just tried to compile vanilla shogun19:44
@HeikoSyep19:44
@HeikoSbut you dont get that right?19:44
CaBaHeikoS: i'm not sure whether i built shogun with my current gcc...19:45
CaBaHeikoS: i upgraded to 6.3 as soon as it was released, because 6.2 started creating annoying warnings after some xcode update... might be that i built shogun before that19:46
CaBaHeikoS: i'll rebuild19:46
@HeikoSok19:46
@HeikoSnot sure what kind of artifacts that might create ;)19:47
@HeikoShttps://gcc.gnu.org/gcc-6/changes.html19:47
@HeikoS?19:47
@HeikoShttps://gcc.gnu.org/projects/cxx-status.html#cxx1z.html19:48
@HeikoSah that will be cool to have19:48
@HeikoSin like 10 years ;)19:48
CaBaHeikoS: hm my shogun build isn't all the way through yet but i think it has passed the critical point20:02
CaBaHeikoS: so i can't reproduce the error by just building shogun as is20:02
@besser82_CaBa, Which problem?20:10
-!- besser82_ is now known as besser8220:10
CaBabesser82: when i include a normalizer header in my custom kernel, it's compilation unit won't compile anymore20:12
CaBabesser82: see error at 19:36:1320:13
CaBabesser82: http://files.photomics.org/tmp/comp_error.png20:14
@besser82CaBa, I know about that one…  That is some cr4zy hell of when #include what…  -_-20:14
CaBayep...20:14
@besser82CaBa, Might even happen when building Shogun…  (class_list.c)20:15
CaBabesser82: do you have a secret order of includes for me to work around this? ;)20:15
CaBabesser82: yeah, see #345920:15
@besser82I didn't dig further into this…  Since I'm more focussing on going towards making shogun more modular and fade away such old stuff like class_list.c20:16
@besser82CaBa, ^20:16
CaBabesser82: hm k...20:17
@besser82CaBa, Sry, I don't have any better news…  :(20:19
CaBabesser82: well... i'll look into the include order of other kernels that use normalizers in member functions... maybe i can figure something out.20:19
@besser82CaBa, yeah…  Maybe…  lisitsyn, do you know any helpful about this ^ ?20:21
CaBathe lhs != rhs case in the kernel - that's what happens when machines are applied rather than trained?20:52
@besser82CaBa, sry. been away;  that's a topic you should ask HeikoS or wiking about…  I'm more into system-architeture then "technical" topics21:31
