ios - Undefined symbols to framework when building application separated to library and application part -


i have application separated library part , application links library. library uses afnetworking, , requires systemconfiguration , mobilecoreservices frameworks. added build process , library builds nicely.

why need add same frameworks application part in order build , not see linking errors?

is not enough link library?

i assume library static library. adding frameworks when building static library in order access include files; not linking frameworks. because static library not linked when it's built; it's collection of object files. try command line list object files:

$ ar t /path/to/my/library.a

when static library linked app binary must provide libraries , frameworks of both, if object files in static library had been part of app binary source tree.

just think of static library simple collection of object files , should make sense you.

java - Multi-Label Document Classification -

i have database in store data based upon following 3 fields: id, text, {labels}. note each text has been assigned more 1 label \ tag \ class. want build model (weka \ rapidminer \ mahout) able recommend \ classify bunch of labels \ tags \ classes given text. i have heard svm , naive bayes classifier, not sure whether support multi-label classification or not. guides me right direction more welcome! the basic multilabel classification method one-vs.-the-rest (ovr), called binary relevance (br). basic idea take off-the-shelf binary classifier, such naive bayes or svm, create k instances of solve k independent classification problems. in python-like pseudocode: for each class k: learner = svm(settings) # example labels = [class_of(x) == k x in samples] learner.learn(samples, labels) then @ prediction time, run each of binary classifiers on sample , collect labels predict positive. (both training , prediction can done in parallel, since problems assumed ...
