[Boost-bugs] [ boost-Bugs-897250 ] boost::mutable_queue constructor with iterators
by SourceForge.net 14 Feb '04

14 Feb '04

Bugs item #897250, was opened at 2004-02-14 22:45 Message generated for change (Tracker Item Submitted) made by Item Submitter You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=897250&group_i… Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Cromwell Enage (expaler) Assigned to: Nobody/Anonymous (nobody) Summary: boost::mutable_queue constructor with iterators Initial Comment: Constructing a mutable_queue using container.begin() and container.end() causes the elements in container to be inserted twice into the mutable_queue. This is because the mutable_queue's internal container c is first initialized with the same iterators, thus already inserting the elements into c, and then the while loop inserts the elements into c again. Changing c(first, last) to c() in the constructor should fix the bug. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=897250&group_i… ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.

indirect_pmap
by Cromwell Enage 14 Feb '04

14 Feb '04

Does anybody remember (or, is anybody actively) using the indirect_pmap functor class template defined at <boost/pending/indirect_cmp.hpp>? A Google search within the Boost site turned up empty. Sifting through most of the graph source code (haven't yet looked at the detail subfolder) was also fruitless. Nevertheless, my documentation quest continues...

future of boost.threads
by Burc Arpat 14 Feb '04

14 Feb '04

i was actually waiting for the rush of the new release to go away to ask this question: i have seen some recent discussions regarding the threads library and from what i gathered there are plans to start working on it again. but, it also seems the original owner of the lib has disappeared from the list here at the petroleum eng. dept. of stanford university, we use boost rather heavily and lately we started into looking parallelization issues. we, of course, would like to use a cross-platform library such as boost.threads but are a bit worried about the future of it so, i guess, the questions are: is there gonna be a new release of boost.threads? if so, are there any plans to change the interface to a degree that it will require significant changes in the user code? with that said, let me also state that, i will be more than glad to give full test support for the library if any changes are being considered burch - - - G.

Building boost::filesystem without bjam
by Joe Gottman 14 Feb '04

14 Feb '04

I just upgraded to boost 1.31. I use filesystem with MSVC 6.0, but I don't use the jamfiles to create my .dsp and .dsw files. I just created simple projects myself. It worked previously, but now when I try to include the filesystem.dll file, I get the error LINK : fatal error LNK1104: cannot open file "libboost_filesystem-vc6-mt-gd-1_31.lib" Do you have any suggestions?

boost random question
by Neal D. Becker 13 Feb '04

13 Feb '04

For the new random number generators, if I want to share a single underlying uniform random generator, I need to do like so: typedef boost::mt19937 rng_t; rng_t rng; boost::variate_generator<rng_t&, boost::normal_distribution<> > tn (rng, boost::normal_distribution<> (0, sqrt (var))); boost::variate_generator<rng_t&, boost::pnseq_generator<1> > pn (rng, boost::pnseq_generator<1>()); That is, I need to say "rng_t&" for the 1st template param rather than "rng_t". Is this correct? The old rng lib passed the engine by ref in the constructor, but the new one doesn't. Correct?

libs/iterator/doc/iterator_facade.html typo?
by Angus Leeming 13 Feb '04

13 Feb '04

libs/iterator/doc/iterator_facade.html#tutorial-example In the section "Template Arguments for iterator_facade" is the subsection "CategoryOrTraversal". I suspect that should be "CategoryOfTraversal" (s/Or/Of/). The iterator_adapter docs spell it "CategoryOrTraversal" too. Regards, Angus

If it runtime errors you could rely on "expected errors" feature. You are right for compile time errors, though one could try to ifdef part of test program. Gennadiy.
