Hi I have an old version of boost 1.33.1. I want to build it with a custom gcc binary whih is in a path other than default.

Hello, I'm using Boost.Interprocess in order to get a single portable source code between Windows and Linux using Mutexes and Shared Memory. Documentation says that, for Windows, the API default behaviour is emulation with mapped files, which is the case (:D).

Hi, Is it possible to evaluate, whether a certain argument type given to a functor will lead to a valid expression with the result_of template? i am trying to achieve the following, maybe there is a better way to do it: template<class T, class F> Container< typename boost::result_of<F(T)>::type > transform( Container<T> c, F f, std::disable_if<valid_expression<F(Block<T>) > >::type* dummy = 0 ){ //slow default implementation … [View More]

In C++, I have a boost::python::object that is wrapping ... something. I'd like to find out what. If I were in python land, I'd call the built-in 'type' function on it. What do I do in C++? Thanks in advance, -- Eric Niebler Boost.org

Problem with boost 1.53 compilation in Windows
by DUNDEK Ivan 08 Feb '13

08 Feb '13

Hi. We are using boost in our project, and now with 1.53 and some added options we are unable to compile the boost in Windows. In Linux, the build is OK. It seems, that when compiling under Windows, the path for compiled boost obj files depends on the options specified, so if there are many options specified, the path become too long. With reduced number of options, the build is OK.
