libtorrent-rasterbar and Visual Studio 2013

Question

I'm trying to build a simple code (examples/simple_client.cpp) using libtorrent-rasterbar with VS2013 (C++), but I get the following linker error:

error LNK2019: unresolved external symbol "void __cdecl libtorrent::rel_performancetimer_pools_nolog_resolvecountries_deprecated_nodht_ext_(void)" (?rel_performancetimer_pools_nolog_resolvecountries_deprecated_nodht_ext_@libtorrent@@YAXXZ) referenced in function "public: __thiscall libtorrent::session::session(struct libtorrent::fingerprint const &,int,unsigned int)" (??0session@libtorrent@@QAE@ABUfingerprint@1@HI@Z)

I compile libtorrent using: bjam toolset=msvc-12.0 link=static variant=debug boost=source and link everything in VS:

• libboost_system-vc120-mt-gd-1_55.lib
• libboost_date_time-vc120-mt-gd-1_55.lib
• libtorrent.lib

Additional info: libtorrent-rasterbar-0.16.15; boost_1_55_0; Windows 8.1 64bits.

Any ideas on what's going wrong here?

Thank you.

Answer 1

After some research and tests, I managed to build the project. That's what I did:

1. Compiled using bjam toolset=msvc-12.0 geoip=off resolve-countries=off link=static variant=debug boost=source that way geoip and resolve-countries is disabled.

2. Using @Hernán's tip of checking the libtorrent RSP files, I got the following preprocessor definitions:

   • BOOST_ASIO_SEPARATE_COMPILATION
   • BOOST_ALL_NO_LIB
   • BOOST_ASIO_ENABLE_CANCELIO
   • BOOST_ASIO_HASH_MAP_BUCKETS=1021
   • BOOST_EXCEPTION_DISABLE
   • BOOST_SYSTEM_STATIC_LINK=1
   • TORRENT_DISABLE_GEO_IP
   • TORRENT_DISABLE_RESOLVE_COUNTRIES
   • TORRENT_USE_I2P=1
   • TORRENT_USE_TOMMATH
   • UNICODE
   • WIN32_LEAN_AND_MEAN
   • _CRT_SECURE_NO_DEPRECATE
   • _FILE_OFFSET_BITS=64
   • _SCL_SECURE_NO_DEPRECATE
   • _UNICODE
   • _WIN32
   • _WIN32_WINNT=0x0500
   • __USE_W32_SOCKETS

3. I added these definitions in VS. For debug configuration, one more definition was necessary: TORRENT_DEBUG (important).

Some websites I used:

• https://code.google.com/p/libtorrent/issues/detail?can=2&q=545&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary&sort=-id&id=545
• libtorrent unresolved external

Thank you for the help.
