Problems installing Boost OSX 10.4.11
by Mine 23 Sep '08

23 Sep '08

Hi, I am trying to install Boost 1.35.0_2 as it is a requirement of installing mkvToolnix. I have installed Boost using MacPorts. When I try to install mkvToolnix I get the following error: *** Not checking for wxWidgets: disabled by user request checking for magic_open in -lmagic... no checking for boostlib >= 1.20.0... yes checking whether the Boost::Regex library is available... yes checking for main in -lboost_regex-mt... no checking for main in -lboost_regex-boost_regex-mt... no configure: error: Could not link against boost_regex-boost_regex-mt ! Error: Status 1 encountered during processing. Am I right in thinking that not all the required libraries are being install and if so, how do I configure the install to include them. Thanks, Terrence

error C2733 second C linkage of overloaded function InterlockedIncrement not allowed
by menuthaur 23 Sep '08

23 Sep '08

Hello, I'm a newbie in using boost. First : For programming I'm using Visual Studio 2008 with SP1 (german edition) and the target platform is Windows CE 6.0 with PXA270 (XScale, ARMVI) processor. And i'm using the STL delivered with Visual Studio. If i include shared_ptr.hpp i get at compiling the errors : "error C2733 second C linkage of overloaded function 'InterlockedIncrement' not allowed." "error C2733 second C linkage of overloaded function 'InterlockedDecrement' not allowed." "error C2733 second C linkage of overloaded function 'InterlockedCompareExchange not allowed." "error C2733 second C linkage of overloaded function 'InterlockedExchange' not allowed." "error C2733 second C linkage of overloaded function 'InterlockedExchangeAdd' not allowed." All errors are targeting to the file interlocked.hpp line 55-63. So my question is, what can i do to solve this problem ? Regards, Marcus Gehr

App will not run when linked to boost thread library
by kittymaguire 23 Sep '08

23 Sep '08

Hi I have added boost::threads to our mac application, which means that I have to build the boost thread library. I have manage to build the universal boost static and dynamic library. When I add the static library to the project, the project builds with no problems and the dynamic library produced it added to the application package. However as soon a I try to run the application, the application fails with the error that it cannot load the dynamic library. Is there a tool on the mac to determine why a dynamic library does not load. Does anyone know why boost is causing this problem. The dynamic library to built on 10.5 with 10.4 framework. The version of boost is 1.36.0 Thanks in advance Katherine -- View this message in context: http://www.nabble.com/App-will-not-run-when-linked-to-boost-thread-library-… Sent from the Boost - Users mailing list archive at Nabble.com.

1.36 Threads/ASIO causing SEGV when cleaning up thread specific storage
by spiderlama 23 Sep '08

I am trying to run my unit previous unit tests with the new 1.36 release, but SEGV is being thrown upon exit. No faults are thrown using 1.34.1, and no code is changed between versions.

Expanding mpl::vector into mpl::matrix
by Joel Falcou 22 Sep '08

22 Sep '08

I wanted to know what's the best to build my own compile-time container that acts as a 2D matrix of integers and reuse most of MPL components. I thought to have a matrix defined as a vector of vector and provide my own at<M,I,J> meta-functions. Were they any attempt at such a thing already tried ? Thanks in advance.

[asio] boost::system::error::success passed to handler
by Nick Milkovits 22 Sep '08

22 Sep '08

Hi, I am working with the mulitcast receive example from http://www.boost.org/doc/libs/1_36_0/doc/html/boost_asio/example/multicast/…. The issue I am having is that every time I receive a packet it gets printed as expected but the receive handler is then called again and this time the if (!error) test fails. Printing the error always gives the message 'Success'. This seems a bit unusual and I am wondering if I there is a way to have the library not generate these success error messages or if I will have to handle getting a success error after every time I receive a packet? Thanks in advance, -- Nicholas Milkovits Software Engineer Acquire Media 3 Becker Farm Rd, Suite 401 Roseland, NJ 07068 973-577-1237

Linker errors with boost thread 1.36
by NFarnsworth＠web.de 22 Sep '08

22 Sep '08

Hello, I got some linker errors when I use the new boost thread library 1.36. together with the Visual Studio 2008. The linker error appears when I use the method create_thread: _guiThread =_threads.create_thread(gui_thread_starter); The error message is: error LNK2022: metadata operation failed (8013119F) : There is a typeref without the necessary suitable typedef If I comment this line the linker error wont appear. I linked the thread library dynamically to my library by using the definition: #ifndef BOOST_THREAD_USE_DLL #define BOOST_THREAD_USE_DLL #endif #ifndef BOOST_ALL_DYN_LINK #define BOOST_ALL_DYN_LINK #endif I compiled the library with the /clr option. Best regards and thanks for your help in advance. Niklas ________________________________________________________________________ Schon gehört?

boost.serialization throwing bad_alloc
by James Vanns 22 Sep '08

22 Sep '08

When using a stringstream in binary mode along with the non-portable binary archive occasionally I see the serialization code throw bad_alloc when reconstructing an object. It appears to be when trying to serialize a derived stl map. We derive from std::map in our project to add a few more convenience methods and a simpler interface and I then added the following code to serialize this newly derived type: template<class Archive> void serialize(Archive &p_archiver, foobar::ResourceMap &p_map, const unsigned int version) { p_archiver & base_object<map<foobar::ResourceMap::key_type, foobar::ResourceMap::mapped_type> >(p_map); } I assume that is OK? It appears to work most of the time. Could it be that when that map is empty it encounters odd behaviour? I pass, to the archive constructor, the no_header flag - is this a problem? I haven't tried the text archivers yet. This is with Boost version 1.35 on an x86-64 Linux installation (gcc 4.1.2) . I get the same behaviour with and without optimisation (-O0 -g3 and -g0 -Os) and with an unlimited stack size and a limit of ~10M. Has anyone else seen similar behaviour. Using a hash function (SHA1) I can see that the same bytes that make up these messages (in our protocol classes are serialized in the payload of messages) are sent to and from the peers so I am pretty sure (though not 100% yet) it isn't due to any corrupt or incorrect data in the underlying stringstreams (the string streams are essentially made up of the message payload) themselves.
