zeule commented 8 years ago

You have an unclean build problem, most likely.

perfect7gentleman commented 8 years ago

what do you mean ? 3.3.4 builds fine.

zeule commented 8 years ago

It builds without errors here using libtorrent 1.1.0 (albeit using cmake but not autotools/qmake). Guess you mistyped the version and are using libtorrent 1.1.0 too.

Might it be that you use a qBt build directory where you did build qBt against another libtorrent version and some files are not rebuilt (due to imperfect dependency tracking, for instance)?

perfect7gentleman commented 8 years ago

of course, 1.1.0. I use Gentoo, and its qbittorrent-9999 ebuild. before yesterday everything was okay.

zeule commented 8 years ago

I'm on Gentoo using live ebuilds too. If Since the build fails in a clean build directory, could you, please, a) try cmake (I can share you an ebuild, if you like), b) let us know your compiler version, and c) share your libtorrent ebuild?

except EXTRA_ECONF and CXXFLAGS our build environments are equal. However, why do I see Cyrillic compiler error messages in your log while your LANG="en_US.utf8"?

perfect7gentleman commented 8 years ago

Cyrillic is maybe of distcc, the other PC uses LANG="ru_RU.utf8"

zeule commented 8 years ago

In the meantime, I did a qmake build and it was successful.

zeule commented 8 years ago

Cyrillic is maybe of distcc...

Could you make a local build, please?

perfect7gentleman commented 8 years ago

i've rebuilt rb_libtorrent locally without EXTRA_ECONF, and try to build qbittorrent locally without EXTRA_ECONF, but the same error

zeule commented 8 years ago

Can't see any significant difference between your and my build environments... Could you share build.log files then, please?

mine: _ZN10libtorrent14session_handle14wait_for_alertENSt6chrono8durationIlSt5ratioILl1ELl1000000000EEEE With c++filt:

libtorrent::session_handle::wait_for_alert(boost::chrono::duration<long, boost::ratio<1l, 1000000000l> >)
libtorrent::session_handle::wait_for_alert(std::chrono::duration<long, std::ratio<1l, 1000000000l> >)

Try to rebuild adding -std=c++11 to the libtorrent compile flags, please.

zeule commented 8 years ago

And your qBt compilation error shows that it was looking for std::chrono, which is natural because qbt forces C++11 mode.

perfect7gentleman commented 8 years ago

thanx, evsh

maxou2600 commented 8 years ago

Same problem, re-building libtorrent with -std=c++11 does not help, I put this at the end of the line CFLAGS in the Makefile of libtorrent build folder. Is this right ? I don't think so, otherwise it would not have some errors during the Qbittorrent build...

EDIT : Found the error : Need to put -std=c++11 at CXXFLAGS and not CFLAGS, after recompiling libtorrent, just needed to rebuild qBittorrent, and it went fine :)

UnitedMarsupials-zz commented 7 years ago

I'm getting the same error trying to build qbittorrent-3.3.7 against libtorrent-rasterbar-1.1.1. Adding the suggested -std=c++11 to the latter's compiler-flags causes the following error:

Using clang-3.4.1 on FreeBSD-10.3 here. Please, advise.

Ok, adding -DBOOST_ASIO_HAS_STD_CHRONO to the CXXFLAGS of libtorrent-rasterbar instead of -std=c++11 produces a library, that allows qbittorrent to link. Using it right now.

-std=c++11 solved my problem thank you very much
