Boost linker error: Unresolved external symbol “class boost::system::error_category const & __cdecl boost::system::get_system_category(void)”

Question

I\'m just getting started with Boost for the first time, details:

1. I\'m using Visual Studio 2008 SP1
2. I\'m doing an x64 Build
3. I\'m using boost:

Answer 1

I solved the problem. I had built 32-bit libraries when I had intended to build 64-bit libraries. I fixed up my build statement, and built 64-bit libraries, and now it works.

Here is my bjam command line:

C:\Program Files (x86)\boost\boost_1_38>bjam --build-dir=c:\boost --build-type=complete --toolset=msvc-9.0 address-model=64 architecture=x86 --with-system

Answer 2

I needed both versions and used stage target, so I used --stagedir=./stageX86 for x86 version and the default ./stage for x64

Answer 3

You need to link in the boost_system library

Answer 4

I also came here from for this linker error plus CMake, but in my case it was the fact that CMake by default will try to build with 32bit by default. This was fixed by specifying -Ax64

cmake -Ax64 {path to CMakeLists.txt}
