main issue

i trying build homework project involving linked lists , custom classes, when build project, following 3 linker errors...

1>customerimp.obj : error lnk2019: unresolved external symbol "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl operator<<(class std::basic_ostream<char,struct std::char_traits<char> > &,class linkedlisttype<class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > > const &)" (??6@yaaav?$basic_ostream@du?$char_traits@d@std@@@std@@aav01@abv?$linkedlisttype@v?$basic_string@du?$char_traits@d@std@@v?$allocator@d@2@@std@@@@@z) referenced in function "public: void __thiscall customertype::printrentedvideo(void)" (?printrentedvideo@customertype@@qaexxz) 1>testvideostore.obj : error lnk2019: unresolved external symbol "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl operator<<(class std::basic_ostream<char,struct std::char_traits<char> > &,class linkedlisttype<class videotype> const &)" (??6@yaaav?$basic_ostream@du?$char_traits@d@std@@@std@@aav01@abv?$linkedlisttype@vvideotype@@@@@z) referenced in function _main 1>testvideostore.obj : error lnk2019: unresolved external symbol "class std::basic_ostream<char,struct std::char_traits<char> > & __cdecl operator<<(class std::basic_ostream<char,struct std::char_traits<char> > &,class linkedlisttype<class customertype> const &)" (??6@yaaav?$basic_ostream@du?$char_traits@d@std@@@std@@aav01@abv?$linkedlisttype@vcustomertype@@@@@z) referenced in function _main

i've done lot of programming, have never run across linker errors until now, i'm having trouble deciphering , debugging errors. i've put zip file original source code solution file "built" project in public dropbox @ link below. using visual studio 2012 on 64-bit windows 8 computer. build specs set debug / win32 platform.

https://dl.dropbox.com/u/101002796/rinehart-p07v2.zip

additional notes:

  • the majority of source book source, , doesn't seem have errors
  • no thoughts instructor. clueless was
  • i've tried building in windows 7 dev environment no luck.
  • i've tried adding implementations header files, still same errors
  • i've tried many other solution steps forums/blogs/etc, nada worked

quick appreciated have huge stack of calculus finish before programming project due, work part-time, , married (married people should understand), nasty little debugging issues bane on productivity.

thanks million in advance, ~sean r.

i've tried installing (and re-installing) android studio several times now, , each time, studio isn't able create new android project. when attempt initial android studio window (ie. basic 'create', 'open', 'import' etc options), i'm asked of questions in wizard, brief progress dialog, followed nothing @ all. if open incomplete project process creates choosing 'open' list, can try choosing create new android project menu. this has same issue, error message in output console time... java.lang.noclassdeffounderror: com/sun/xml/internal/bind/v2/model/annotation/annotationreader (wrong name: com/sun/xml/internal/bind/v0/model/qnnotation/annotationreader) note: when installed android studio, installed incompatible jdk (1.8, not 1.7). have had go default project settings change jdk uses 1.8. does know how can avoid this? there place should downloading jxb classes? missing in java paths? this appears have been caused cor

Decoding a Python 2 `tempfile` with python-future -

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
