Guest96150blackburn, windows did it btw  - it destroyed my linux partition on the other harddrive20:12
blackburnGuest96150: fantastisch20:12
Guest96150and I was already wondering why I could install w7 at all20:13
Guest96150superior technology20:13
Guest96150so it will probably take me a few days before I am operational again20:14
blackburnwhy you did install it?!20:15
Guest96150wanted to get shogun running under cygwin20:16
blackburnah20:16
Guest96150but hey - internet broke here today, our build machine crashed after > 1month of uptime with some kernel panik20:17
Guest96150so yeah baby ...20:17
blackburnBrianC_: sad news20:18
BrianC_?20:20
blackburnBrianC_: that our fix is not a fix :)20:20
BrianC_ah20:20
BrianC_btw Guest96150, you can restore the linux partition via grub on a live CD20:20
BrianC_it just wipes the MBR, not the actual partition20:21
blackburnagree20:22
Guest96150unfortunately not20:23
Guest96150it installed some few MB of boot loader crap20:23
blackburnooooh20:23
Guest96150onto my linux partition20:23
Guest96150so it is mostly gone20:24

BrianC_always best to sandbox windows in a virt, only exception is if you need drivers for games or something20:25
blackburnBrianC_: all ok with regression_svrlight on my machine..20:33
BrianC_odd20:34
BrianC_hmm i manually incerted the fix into kernel.cpp20:34
BrianC_and recompiled20:34
blackburnwhy manually?20:35
BrianC_version on git doesnt build correctly for me20:35
blackburnwhat is the error?20:35
BrianC_undefied method: StreamingSparseFeatures.get_feature apparently20:35
blackburn?!20:36
blackburnhow it can be..20:36
BrianC_not sure actually i did see the code for that method in StreamingSparseFeatures.cpp20:36
BrianC_and modshogun.py has it defined as well20:36
BrianC_well it cant find it in _modshogun.so20:36
BrianC_build should have returned a link error, no?20:37
blackburnthat's really odd20:37
blackburnGuest96150: any ideas?20:37
BrianC_  File "/home/mike/brian/lib/python2.7/dist-packages/modshogun.py", line 26, in swig_import_helper     _mod = imp.load_module('_modshogun', fp, pathname, description) ImportError: /home/mike/brian/lib/python2.7/dist-packages/_modshogun.so: undefined symbol: _ZN6shogun24CStreamingSparseFeaturesIiE11get_featureEi20:37
BrianC_is the exact error if that helps20:38
blackburnBrianC_: have you tried to 'git clean -dfx' and reconfig/rebuild?20:38
BrianC_ive tried 'make clean' since I don't have git installed ont hat machine20:38
blackburntry make distclean20:39
blackburnit could be some junk left from wrong compilation or so20:40
