| mikeling | wiking: HeikoS how could I check the content of CLabels and CFeatures when I use gdb to debug them? | 12:57 |
| mikeling | I mean when I try to print out a CFeatures or CLabels object like labels_test, it can only give me something like **(shogun::CMulticlassLabels *) $13 = 0x0000000109300710** how could I know what exactly looks like in a CFeatures or CLabels | 12:58 |
| mikeling | could I got a matrix or numbers or string or anything else readable context of it? | 12:59 |
| mikeling | And what's the meaning of 0x0000000107fc0bb0 in https://pastebin.mozilla.org/8962085? | 13:02 |

| mikeling | Hello, when I try to create a file(https://pastebin.mozilla.org/8962102) to test SGVector I got error like https://pastebin.mozilla.org/8962104 | 13:38 |
| mikeling | could anyone tell me why that happened and how to fix it? Thank you :) | 13:39 |
| lisitsyn | mikeling: how do you compile it | 13:45 |
| lisitsyn | it's a linker error | 13:46 |
| lisitsyn | you likely miss -lshogun | 13:46 |
| mikeling | lisitsyn: hey! Thank you for your help! I just use clang++ 'file name' | 13:47 |
| mikeling | so how could I link it? | 13:48 |
| lisitsyn | mikeling: add -lshogun | 13:48 |
| lisitsyn | to your compiler flags | 13:48 |
| mikeling | could I write it in CMakeLists.txt? | 13:49 |
| mikeling | lisitsyn: when I try to remake the whole project, it will give me a link error https://pastebin.mozilla.org/8962113 | 13:56 |
| mikeling | could you tell me how to fix that? | 13:56 |
| mikeling | I'm sure I had run cmake -DENABLE_TESTING=ON -DCMAKE_BUILD_TYPE=Debug -DDEBUG=ON ../ before I make && make install it | 13:56 |

| mikeling | usually I need to delete the whole project and reclone it if I want to move on | 13:58 |

| lisitsyn | mikeling: oh didn't know you're using cmake | 14:23 |
| lisitsyn | what's your cmakelists? | 14:23 |
| mikeling | lisitsyn: you mean the "ld: symbol(s) not found for architecture x86_64" error I just asked? my cmakelists is https://pastebin.mozilla.org/8962134 which is created by Clion | 14:30 |
| lisitsyn | mikeling: ok didn't know you're using clion :) | 14:30 |
| lisitsyn | there must be some stuff to link libraries | 14:30 |
| lisitsyn | just link your program to shogun to make it work | 14:31 |
| lisitsyn | you will get some LINK_LIBRARIES | 14:31 |
| lisitsyn | in your cmakelists | 14:31 |
| lisitsyn | that's not shogun-specific, you gotta do that for any library you use | 14:31 |
| mikeling | and I just fix the second error (the duplicate symbol), I think it's about the Clion create a camke-file-debug folder which conflict with the CMakelist of shogun itself | 14:31 |
| mikeling | lisitsyn: oh great! Thank you very much | 14:32 |
| lisitsyn | ping me if it works | 14:32 |
| lisitsyn | or not :) | 14:32 |
| mikeling | lisitsyn: I'm a newbie for shogun and only some basic idea of C++, so I have no idea how to use the CFeature, SGVector | 14:33 |
| mikeling | sure thing, thank you | 14:33 |
| mikeling | :) | 14:33 |
| mikeling | lisitsyn: actually I'm working on this issue, but I don't know how to use those because objects like SGVector or distance, so I'm trying to figure them out these days :) | 14:36 |
| mikeling | lisitsyn: hmmm, it doesn't work by "add_library(shogun SHARED $<TARGET_OBJECTS:libshogun>)" with https://pastebin.mozilla.org/8962143 | 14:44 |
| lisitsyn | why add_library? | 14:44 |
