问题
I am trying to compile my program but it wouldn't link at all. I have specified the path to the boost lib files and the linker still complain. Here's the linking error I got:
1>Edproj.obj : error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAABVerror_category@12@XZ)

More info:
I am running a 64-bit Windows 8 Pro and I compiled boost with the following option
bjam --build-type=complete --toolset=msvc10.0 address-model=64 architecture=x86 variant=debug,release threading=multi link=static runtime-link=static
Can someone tell me what is wrong?
Update:
After changing to boost 1.51 it got rid 7 out of 8 of those linker errors but this one is still persistent
error LNK2001: unresolved external symbol "void __cdecl boost::throw_exception(class std::exception const &)" (?throw_exception@boost@@YAXABVexception@std@@@Z)
I don't get what is going on here. This one is from boostpro 32 bit installer. It couldn't have something to do with my source file right?
Update :
Ok I have solved this problem for boost 1.51. Turns out in the Property Pages >> C/C++ >> Code Generation >> Enable C++ Exceptions was turn off for me.
OK. I will attempt to see if the same settings solve the problem for boost 1.52. Will update later.
回答1:
I had the same problem before: I build boost lib with default parameters which run bootstrap.bat directly.
if you use boost::system in your project, you should use and appoint x86 or x64 version of boost::system lib.
you can recompile boost lib with this bat, save these to boost root folder and run it in CMD windows(don't double click!):
call "%VS140COMNTOOLS%..\..\VC\vcvarsall.bat" x86
cd boost_1_60_0
call bootstrap.bat
rem Most libraries can be static libs
b2 -j8 toolset=msvc-14.0 address-model=64 architecture=x86 link=static threading=multi runtime-link=shared --build-type=minimal stage --stagedir=stage/x64
b2 -j8 toolset=msvc-14.0 address-model=32 architecture=x86 link=static threading=multi runtime-link=shared --build-type=minimal stage --stagedir=stage/win32

Thank looks to me like its no auto linking correctly.
Include path is boost152/ only
Library path is boost152/stage/lib

Be sure to add the right directories into the linker properties.
Read this post to further details Boost linker error: Unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::get_system_category(void)"
Also you've got to add this path into Linker addition directories:
$(BOOST_ROOT)\bin.v2\libs\thread\build\msvc-xx.0\release\address-model-64\link-static\threading-multi
where xx is your visual studio version
回答4:
These two defines below were messing up with my linker, throwing one beautiful "LNK2001: unresolved external symbol" error. Do you have then somewhere in your code?
//#define BOOST_FILESYSTEM_NO_DEPRECATED
//#define BOOST_FILESYSTEM_NO_LIB
