提升LNK2019错误

Question

I read through the boost documentation using the '5.3.4 Invoke b2' and followed up with forum threads that explained details of linking the boost library to the header and linker directories , in the boost help '4.1 Build From the Visual Studio IDE', and found this cool boost related wiki that explained the bjam.exe controls .

placed #include <boost/thread/thread.hpp> in the main.cpp

And, I get this linker error, and the existing help threads have identified the problem is with x64:

• Directory path and x32/x64
• unrelated to Visual studio
• unresolved

The error:

error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::generic_category(void)" (?generic_category@system@boost@@YAAEBVerror_category@12@XZ) referenced in function "void __cdecl boost::system::`dynamic initializer for 'posix_category''(void)" (??__Eposix_category@system@boost@@YAXXZ)  main.obj

error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAAEBVerror_category@12@XZ) referenced in function "void __cdecl boost::system::`dynamic initializer for 'native_ecat''(void)" (??__Enative_ecat@system@boost@@YAXXZ)  main.obj

they are similar, something about 'posix_category' and something about 'native_ecat'

So, I tried to build the x64 boost library, and found conflicting instructions on where to put these:

• did not say "Note for x64 users: Add the address-model=64 option to bjam (after the threading argument) in order to build static libs with the 64-bit compiler."
• cant find the link but one said to place x64 lib in the vs2008 bin?

Also, I tried changing the vs2008 configuration back to x32 -> solutionExplorer/solution_properties/configuration_manager/active_solution_platform - Win32, closed and reopened visual studio - relinked the additional directories C/C++/general and Linker/general to Boost/root and Boost/stage/lib - and it compiled without error.

My best guess at the b2 commands is --toolset=msvc-9.0 address-model=64 --build-type=complete --stagedir=lib\\x64 stage

Please give concise instructions for how to build and install x64 version of boost on VS2008. Also, what was the wiki talking about for release and debug - they are not in Boost invocation ?

Answer 1

use c++ 11

It more or less includes all the features of boost I wanted to use, also compiles in g++ without figuring out how to build the boost library on my university server and then reference into a remote g++ build - pretty much solved everything with that
