Unable to link Boost libs to vs2010

Question

I know this question has been asked a lot of times here. But after trying all the mentioned solutions I am still not able to Compile the Test Boost code.

I have followed the following Steps for installation :-

1. Unzip Boost into a new directory.
2. Start a 64-bit MSVC command prompt and change to the directory where Boost was unzipped.
3. Run: bootstrap
4. Run: b2 toolset=msvc-10.0 --build-type=complete --libdir=C:\\Boost\\lib\\x64 architecture=x86 address-model=64 install
5. Add C:\\Boost\\include\\boost-(version) to your include path in Microsoft.Cpp.Win32.user property sheets.
6. Add C:\\Boost\\lib\\x64 to your libs path in Microsoft.Cpp.Win32.user property sheets.

Additionally, I have added the lib path in additional library directory.

I am trying to compile a standard code to test whether boost is working properly or not.

#include <iostream>
#include <boost/shared_ptr.hpp>
#include <boost/regex.hpp>

using namespace std;

struct Hello 
{
    Hello(){ 
        cout << "Hello constructor" << endl;
    }

    ~Hello(){
        cout << "Hello destructor" << endl;
        cin.get();
    }
};


int main(int argc, char**argv)
{
    //Boost regex, compiled library
    boost::regex regex("^(Hello|Bye) Boost$");
    boost::cmatch helloMatches;
    boost::regex_search("Hello Boost", helloMatches, regex);
    cout << "The word between () is: " << helloMatches[1] << endl;

    //Boost shared pointer, header only library
    boost::shared_ptr<Hello> sharedHello(new Hello);

    return 0;
}

The linker error I am getting is:-

What am I missing here? I am using VS2010 and windows 64bit.

Thanks

Answer 1

There were 2 issues which were giving the linker error:-

1. Additional linker dependencies absent at Properties->Linker->Input->AdditionalDependencies

2. Project was win32. Needed to convert it to x64 using configuration manager.
