[Boost State Chart] Where to include, where to declare?
by Philipp Bender 15 Apr '12

15 Apr '12

Hi all, today I face some major problems with the state charts. Mostly this comes from incorrect forward declarations and so on. I use this scheme for e.g. decaring a state which has orthogonal substates. I hope my pseudocode is readable. ############# Outer.h ############## struct Inner1 struct Inner2 struct Outer < Context, InnerDefaults< Inner1, Inner2> > { // implementation } #include Inner1 // this is the really important part #include Inner2 ############## Inner(1|2)… [View More]

Set fusion::vector value with boost::shared_ptr
by Stefan Troeger 15 Apr '12

15 Apr '12

Hello alltogether, I've posted this already in Stackoverflow a week ago with no answer up to now, so I thougth I try it here again. I want to set a value in a fusion::vector at a specific location. This works normaly very well with fusion::at_c(seq) = value, as at_c returns a reference to the object at this position. However, this is not garanted, the documentation only states about the return type: "In most cases, this is a reference". I've encounterd a case where it is not a reference, … [View More]

[Boost] List of not header-only libraries (requiring linking).
by Klaim - Joël Lamotte 14 Apr '12

14 Apr '12

Hi, I was looking on the website about a list of the boost libraries that require linking/ are not header only. Is it correct that this list is what I'm looking for? http://www.boost.org/doc/libs/?view=filtered_autolink If it is, then I think the name is misleading. Automatic linking happens only with visual studio, right? Also, autolink doesn't really mean anything in this context, so maybe something like "Linking Required" would be better? I also found the list I was looking for there: … [View More]

I am looking for users and developers interested in collaborating on an open source sovereign rating model project.

Source will be posted to GitHub on 2 May 2012. The tool uses a Monte Carlo simulation which includes calls to Boost's normal and Cauchy random number generators. There are many … [View More]

Interrupting interprocess::message_queue::receive
by Michael Herrmann 13 Apr '12

13 Apr '12

Hi all, I am receiving messages from a message_queue via the blocking receive(...)-method from a separate boost::thread. When I interrupt this thread, the receive(...)-method never returns (not even with an thread::thread_interrupted exception). Am i doing something wrong or could this be a bug in message_queue? The situation I am talking about is illustrated by the following program never returning: #include <boost/thread.hpp> #include <boost/interprocess/detail/… [View More]
