[bind] binding a boost::reference_wrapper to a function template
by Barchenkov, Alexei (IT) 04 Apr '07

04 Apr '07

Rewording from a previous post: Are there any issues with binding a boost:ref to a free templated function? On gcc32 this generates an error: class Test { }; template <class T> void foo(T arg_) { } int main(int) { Test t; boost::reference_wrapper<Test> tr(t); boost::function<void()> fun1 = boost::bind(&::foo<boost::reference_wrapper<Test> >, tr); // line 41 } - Alex ________________________________ From: Barchenkov, Alexei (IT) Sent: Friday, March 23, 2007 12:55 PM To: boost-users(a)lists.boost.org Subject: question about binding a boost::reference_wrapper argument inside a templated function I am getting an error when compiling the following code on gcc32.

Initialization and shutdown code with boost::unit_test_framework
by Jules d'Entremont 04 Apr '07

04 Apr '07

I have a set of unit tests that require an initialization function to be called once at program startup, and a shutdown function to be called at program exit. Something like this: int main() { init(); // run unit tests fini(); } Is it possible using the unit test framework for me to substitute my own main() function for the one that normally gets run by the framework? Or is there some other way of accomplishing the same thing? Jules d'Entremont.

assign with my container

Hi, I am inheriting a vector for some reason. Just like template<typename T> class my_vector : public std::vector<T>{ }; I want my_vector to take the advantage of boost::assign library. How to do it?

[MultiIndex] typo in tutorial
by Christian Henning 04 Apr '07

Hi there, maybe it has been fixed already. In the section Sequenced Indices there is a type in the sample code. *(s.begin()) == 1; should be *(s.begin()) = 1; Christian

how subslice can be made from some disjoint section ?
by abir basak 04 Apr '07

04 Apr '07

Hi, I have a ublas vector (or it can be std::vector also). Where I want to perform certain operation as a rotating basis. The program below illustrates it. std::vector<int> v; v+=1,2,3,4,5,6,7,8,9; ublas::vector<int> v1(v.size()); std::copy(v.begin(),v.end(),v1.begin()); std::cout<<ublas::sum(ublas::subrange(v1,1,3))<<std::endl; std::cout<<ublas::sum(ublas::subrange(v1,7,2))<<std::endl; In the first case I got a sum for [1 ,3) , I also want to get a sum for [7, 2) in a wrapped (circular )way. So is there any range functionality provides it in that way ? I also want some std algorithms to perform over some iterator adapter in a wrapped way .I can write such iterators , but are they already exist in boost ?

Proper way to change a cached shared pointer

Proper way to change a cached shared pointer
by Stephen Torri 04 Apr '07

Sorry for the duplicate. I hit a weird set of key strokes and the email was sent. I have a class which is containing a shared_ptr to data. This class parses in a XML file and populates the data based upon the contents. There is a memory problem in this file where I reset the shared_ptr. Am I right in interpreting the output of valgrind that the problem is at Line 110 in Formula_Parser.cpp or is it somewhere else? I thought it was in Formula_Parser.cpp so I printed out here what is happening in the function. I am trying to create a Graph pointer where data will be added to it when the XML parser calls back endElement. So I cannot pass the pointer to the graph as a part of the XML calls without editing that library. So I made it a member variable to the class. The idea is that the Graph is populated with Components and then returned at the end of parse(). Am I correctly resetting m_graph?

boost_1_33_1\libs\serialization\vc7ide\Library.vcproj settings
by Oleg V. Zhylin 03 Apr '07

03 Apr '07

Hi, I've just discovered an inconsistency in settings of Library VC7 project for serialization. For Debug builds the target in project settings is libboost_serialization-vc71-s-gd-1_33_1.lib while according to auto_link.hpp "s-gd" should rather be "sgd". Will this be fixed in next release?

Hi, I noticed a new library, Quantitave Unit, is being reviewed. Where can I get a copy of the library? I'd like to compare it to Quan which was reviewed a while ago and see it if suits my needs better. thanks, matthew
