Using: Boost 1.36 Want to build static Filesystem Library for Windows and Linux. Right now I want to make sure the build is successful with the compilers we are using. I am a noobie with Boost and BJam, and am having difficulties building a test application for testing. Unfortunately, I'm dusting off my programming hat and learning to use all the appropriate tools again like compilers etc. I have read through much of the Boost instructions but still cannot seem to get the Filesystem library compiled as a static library and working with practical examples. Question: What is the simplest way to build a library to be used by my other source code out of the Filesystem Library on both Windows and Unix systems? And what is the simplest way to test that build? My first test is on Windows XP with Visual Studio Express 2005. *Attempt 1: *Create App with Visual Studio 2005 I ran the following from main Boost directory on the command line to create the library files: bjam debug --with-filesystem stage I then started a new Win32 Console Application in Visual Studio with the file_size.cpp test example. Under "Additional Include Directories" I put: "C:\Program Files\boost_1_36_0";"C:\Program Files\boost_1_36_0\stage\lib" I then tried to build the solution, and received the following error: LINK : fatal error LNK1104: cannot open file 'uuid.lib' *Attempt 2:* Create App with BJam I navigated to \libs\filesystem\src and created a Jamfile with the following: lib test : operations.cpp path.cpp portability.cpp utf8_codecvt_facet.cpp : <variant>debug <link>static ; I ran bjam in this folder which created a library: libtest-vc80-mt-gd-1_36.lib I copied the file to \libs\filesystem\example and created a Jamfile there with the following: exe FilesystemTest : file_size.cpp libtest-vc80-mt-gd-1_36.lib ; After running bjam in this folder, I received severael unresolved symbol erros like the following: file_size.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::get_system_category(void)" (?get_system_category@system @boost@@YAABVerror_category@12@XZ) referenced in function "public: __thiscall boost::system::error_code::error_code(void)" (??0error_code@system@boost@@QAE@XZ) Any help would be much appreciated!
