c++ - An intrusive list of unique_ptrs? -

-

i have program highly multi-threaded , contains intrusive linked list of objects. need pass off objects in list several threads, 1 thread ever own object @ time, meaning don't need object or pointer shared.

i wanted create intrusive list unique_ptr using boost, i've read unique_ptr not compatible boost intrusive library not have right ownership semantics.

per this intrusive library requires it's elements (pointers) have same ownership semantics raw pointer. unique_ptr or shared_ptr not qualify.

i wondered if give me advice on how best implement intrusive list can safely pass elements through several threads , know being moved thread , not shared amongst threads?

as far follow, work need kind of auto-unlink hooks.

since intrusive container not own objects contains, should not have problem adding raw pointers unique_ptrs refer to, intrusive container.

if need able access actual unique_ptr raw pointer in intrusive list, along lines of enable_shared_from_this might help. (you'd need combine intrusive container intrusive unique_ptr.)

after thinking bit seems there isn't intrusive unique_ptr variant out there, since "intrusive" part smart pointers reference count, , unique_ptr objects not have reference count.

probably best of using shared_ptr this, since has enabled_shared_from_this.

c++ - Compiling static TagLib 1.6.3 libraries for Windows -

i having super hard time compiling , using taglib 1.6.3 in qt project. i've tried can think of. taglib claims supported through cmake i'm not having luck. furthermore, i'm confused kinds of files need qt libs! i've built *.a files, *.lib, , *.dll. understand far... believe since i'm working in windows *.lib want. no matter do, end "undefined references" taglib functions try use when try compile qt project. have tried mingw32, msys, visual studio 2008, , cross-compiling windows on linux. turning nothing. what makes less sense me if compile same taglib source qt on mac (g++ think?) works fine! somewhere in windows compilation procedures have going wrong. have been smacking face on desk 30 (on , off) hours trying figure out. since qt uses mingw must compile taglib same compiler? if compile *.lib's visual studio not compatible? are *.a libraries usable in windows? (assuming mingw) i'm still trying handle on c++ stuff, after reading coun...
