    [boost/thread.hpp] Boost Library 1.51.0 Error in Visual Studio 2010

    Hi,

    I installed Boost Library 1.51.0 and installed BoostPro binary library (boost_1_51)

    The following is my code

    Code:
    #include <string>
    #include <iostream>
    #include <boost/thread.hpp>
    
    using namespace boost;
    using namespace std;
    
    
    int main(){
    
    }
    This generates the following error


    Code:

    if I remove the reference to Boost thread library, it builds successfully
    I could build successfully with reference to other libraries like
    Code:
    boost/function.hpp
    any suggestions? thanks

    Re: [boost/thread.hpp] Boost Library 1.51.0 Error in Visual Studio 2010

    I narrowed down the problem to a conflict between different C++ libraries

    If I remove libpqxx library references in VS project properties, then boost works correctly. If I include it, then the above error in my original post occurs

    Anyway to include other libraries without adding all the entries in "Additional Include Libraries"?

    The /showIncludes option when compiling your program will show you where the errors are occurring.

    Also, you're using the term "library" incorrectly as those errors are compiler errors, not linker errors. A library is something that is used at link time, not compile time.

    thanks for the reply and clarification. I was able to figure it out using \showincludes

    Like I said before, if I removed the libpqxx library from the "Additional Includes Library" field in project properties, leaving only the boost library, I could successfully build and compile code.

    In this project, I noticed that I'm able to use objects from the libpqxx library and build/compile successfully, without having the "Additional Includes Library" field setup to reference the libpqxx. Unlike in a previous project, where I had to set it up as a local project property. So I don't expect other VS projects to be able to reference the libpqxx library, unless I set it up in their project property

    The \showincludes results show that the project is referencing the libpqxx and I'm able to successfully use the #include declarative, though I did not setup the "Additional Includes Library" field to do so. I only configure the linker properties to reference the libpqxx library

    Why is that? Does VS cache the path for all libraries used in previous projects?
    if so, in terms of using libraries, why is there a distinction between having local project properties settings for the library and global project properties where all your projects will be able to reference a specified library

    The C++ compiler include path has nothing to do with the linker include path -- they are two totally separate entities and must be set accordingly.

    The bottom line is that the C++ compiler (CL.EXE) knows nothing about the linker (LINK.EXE), and the linker knows nothing about the C++ compiler. When the compiler compiles the code, the compiler on success creates .obj files that are located somewhere -- the compiler does nothing else.

    The linker now needs to be told where those obj files are located, along with any necessary .lib files needed to link successfully. This step is not done by the C++ compiler -- you have to do that manually (in this case "manually" means you have to set the project linker settings).

    understood.

    How come I did not need to setup the "Additional Includes Library" field to use the libpqxx library?
