geodetic library
by DE 28 Aug '09

28 Aug '09

is there a need for subj? i implemented very accurate direct and inverse geodetic problem routines (as well as geocentric (X, Y, Z) to geodetic (B, L, H) conversion) i used bessel's method to derive the formulas 6 iterations for both direct and inverse routines is enough to converge to full double precision (16 digits) however the formulas themselves provide 9 significant digits that is 1cm accuracy regardless of range (i.e. range = 1m..20000km) to get acceptable accuracy, say, 2 iterations is enough (or even 1) however there are several other aspects uncovered (area and perimeter, projections, etc.) -- Pavel

[spirit] spirit2 PDF docs.
by John Maddock 28 Aug '09

28 Aug '09

While trying to build the PDF's of the spirit2 quickbook documentation I've noticed a few SNAFU's: 1) In the release branch, the docs don't currently build: quickbook.quickbook-to-boostbook ..\..\bin.v2\libs\spirit\doc\msvc-9.0\debug\threading-multi\spirit2.xml Generating Output File: ..\..\bin.v2\libs\spirit\doc\msvc-9.0\debug\threading-multi\spirit2.xml d:/data/boost/branches/release/doc/pdf/../../libs/spirit/doc/qi_and_karma/../../example/qi/mini_xml3.cpp:133: error: Template Redefinition: tutorial_xml3_grammar IMO there's no need to fix this for the release, but if there's an easy fix I can apply locally, then I'll include spirit2 in the PDF doc build. 2) In trunk, there are some unresolved internal links: Making portrait pages on A4 paper (210mmx297mm) Error: no ID for constraint linkend: spirit.qi_and_karma.abstracts.attributes. XLink to nonexistent id: spirit.qi_and_karma.abstracts.attributes Error: no ID for constraint linkend: spirit.qi_and_karma.abstracts.parsing_and_generating.the_tokenize_and_phrase_parse___function.

XLink to nonexistent id: spirit.lex.lexer_tokenizing.the_generate_static_function 3) I've also committed some minor fixes to the Jamfiles in Trunk to get the PDF's building from within doc/pdf OK: see https://svn.boost.org/trac/boost/changeset/55798/trunk Cheers, John.

Re: [boost] [interprocess] shared_memory_object design

Christian Henning escribió: > Hi there, a colleague of mine is questioning the design decisions in > the shared_memory_object class. The assignment operator and copy > constructor are private. Why? Because the class own a unique resource just like a file. Is fstream copyable? No, movable (in c++0x) just like shared_memory_object. What should the copy constructor do?

Ok, this is debatable, because with move semantics you can write: shared_memory_object obj(create? shared_memory_object(create_only, ...): shared_memory_object(open_only, ...)); or shared_memory_object shm; if(create){ shared_memory_object tmp(create_only); tmp.swap(shm); } else{ shared_memory_object tmp(open_only); tmp.swap(shm); } Best, Ion

different matrix library?
by DE 27 Aug '09

27 Aug '09

behold! i've put my lib in the vault/linalg there are sources as well as documentation (zipped html and CHM file) if you are interested you might try to use it or even perform some performance testing (would you mind to post results in that case?) i tried to write documentation so that any user would be able to figure out what's going on and use the lib without difficulties if you'd run through it i hope you get the image of my proposition any constructive comments are welcome -- Pavel ps do anyone know how to kill directories in the vault?

While looking to build PDF's for trunk, I see the graph lib now has quickbook docs, but the [import ../examples/whatever] should all be [import ../example/whatever] In order to find the files. Cheers, John.

[rfc] cppgui
by Felipe Magno de Almeida 27 Aug '09

27 Aug '09

I've been working the past two years, on and off, unfortunately more often not, in a GUI library. But I have gotten back to it. And I wanted to make it usable. I believe there are some great things in it. This library has a named parameter interface which is extensible by the backend implementation. I've been working on a QT port, which have been fairly easy so far. My intention is to rework some parts of it, finish most widgets and the surface concept I've been working on and submit to review to boost. But I wanted some ideas on the controller interface and whatever might be useful too in improving the design before submitting. The library is in http://www.assembla.com/wiki/show/cppgui There's a svn and trac there that I use. The library requires the boost/funcitonal/factory.hpp library reviewed and accepted (?), which is not yet part of any boost distribution to compile. You will also need fusion to compile. I've tested with GCC 4.4.0/4.3.3 with QT and win32 with visual C++ 9.0. But should be pretty portable, including qt in visual C++. The gtk code does not compile :(. There are some very primitive documentation in the site, and some examples in the svn. Thanks in advance, -- Felipe Magno de Almeida

BCP module list from file
by Matthew Chambers 26 Aug '09

26 Aug '09

Hi, I'm automating the creation of a boost subset tarball with bcp and I had to add passing the module list in from a file because the list got so long (and of course piecemeal invocation results in a lot of redundant copying). Is this a feature that someone wants to patch into an official release? I'll attach the diffs; it was a very simple change but it makes the program scalable for larger projects.

All the random zips I have downloaded over the past probably 2 years, probably 80% have been 7z. 7z has been included in all the *nix distro's I have used for the past few years, and most zip programs on Windows supports it just fine as well. 7z compresses a *lot* better then gzip/bzip/zip/etc... Takes more memory and time to do the initial compression, but is fast decompressing. I really doubt you would have any issues opening it, on my Kubuntu install I just click to open it, ditto with my windows.

[1.40.0] [threads] Unmerged threads changesets
by Beman Dawes 26 Aug '09

26 Aug '09

There are at least nine Boost.Threads changesets in trunk that have not been merged into the release branch. They date back to February. There are several multiple-platform trunk test failures that seem related to one or more of these changesets. I pinged Anthony yesterday about one of the changesets, but have had no reply. Given the above, plus the fact that 1.40.0 is really late already, I'm going to go ahead with the release without these changesets. --Beman

Plotting graphs in Scalable Vector Graphics format.
by Paul A. Bristow 26 Aug '09

26 Aug '09

Further to my post advertising Plotting graphs in Scalable Vector Graphics and inviting feedback, I am encouraged by the several ' looks neat' comments. I have now improved the documentation - and even reduced the number of typos a little ;-) (With several hundred options, effective documentation is uncommonly challenging). You will find a PDF documentation at https://svn.boost.org/svn/boost/sandbox/SOC/2007/visualization/libs/svg_plo… /pdf/svg_plot.pdf And source at https://svn.boost.org/svn/boost/sandbox/SOC/2007/visualization Boost Sandbox source code And, in case you were on vacation for my first post, some demo plots are attached for your amusement. Finally - I would like to ask how many of you were deterred from looking at the many examples of plots when you found that Microsoft Internet Explorer failed to render the files (unless you installed the Adobe SVG view add-in - and you couldn't be bothered to do that). Is this (lamentable) lack fatal to people's interest in SVG? Thank you. Paul --- Paul A. Bristow Prizet Farmhouse Kendal, UK LA8 8AB +44 1539 561830, mobile +44 7714330204 pbristow(a)hetp.u-net.com

Comparative analysis of Boost versus ACE
by Dhiman Lahiri 26 Aug '09

26 Aug '09

Hello, We are planning to port our Windows software on to Linux and we were thinking of Boost and ACE as alternatives. But I am not sure as to which one would suit our needs. The things we need from the library would be: 1) Threads, IPC 2) Shared memory abstraction 3) OS calls abstraction I would like to know which one would have a smaller memory footprint. Thanks in advance. Best regards, Dhiman Lahiri

Bug in lexertl library (in Spirit)
by Alejandro Rivero Pérez 25 Aug '09

25 Aug '09

Hi There is a bug in the lexertl library. This library is being used in spirit but being prepared for submission to boost as a separate library. The file consts.hpp contains the lines: const std::size_t num_wchar_ts = (boost::integer_traits<wchar_t>::const_max < 0x110000) ? boost::integer_traits<wchar_t>::const_max: 0x110000; Which should be: const std::size_t num_wchar_ts = (boost::integer_traits<wchar_t>::const_max + 1 < 0x110000) ? boost::integer_traits<wchar_t>::const_max + 1: 0x110000; Currently the lexer will cause a buffer overflow parsing a 0xffff value in a wchar_t buffer (assuming sizeof(wchar_t) is 2). Best regards, Alex

[task] functor passed to a boost::task::task not always destroyed?
by Harald Winroth 25 Aug '09

25 Aug '09

I wrote a short test program to check that each copy construction of a functor passed to a boost::task::task and boost::task::async was balanced by a corresponding destructor call. This is indeed the case when the task is run in a thread pool but it seems as if one destructor call is missing when the task is submitted to to boost::task::async with a boost::task::new_thread execution policy. Here is the a short test program and the resulting output. For comparison, the same functor is also passed directly to a boost::thread, which behaves as expected. The program was compiled using Visual C++ 2005 (SP1), and boost 1.39.0 with the latest Boost.Task library from the vault dropped in. Any ideas? Am I missing something?

As far as I can tell, all the branches/release merges we were waiting for have now been completed. The plan is to go ahead with the release candidate as soon as all the release branch tests have cycled for revision 55757. Please commit no more changes to branches/release without explicit permission from me. Thanks, --Beman

[move][containers] Fast track request response
by John Phillips 25 Aug '09

25 Aug '09

Ion and all, Ron and I have discussed the fast track review requests, and we have decided they should be normal reviews. The Move library is a single header, but that header has a lot of functionality in it. In addition, it is a very good capability to provide so we expect that it will be used heavily from the time it is added until move support becomes commonly implemented in C++0x compliant compilers. So, giving everyone a chance to really dig deep and mull the details is important. The container library is a larger collection of code and will just take some time for people to absorb well enough to review well and so should have a full review. To be clear, this is not intended as a criticism of the quality of the code and documentation, but instead a recognition of how important it is likely to become. So, we want to make sure it gets a thorough review. Thanks to Ion for producing the libraries, and to the future reviewers for their input. We strongly encourage review manager volunteers to step forward so we can schedule the reviews quickly. John Phillips Ron Garcia Review Wizards

[UUID] uuid.hpp Objective C++ conflict.
by M M 25 Aug '09

25 Aug '09

Hello, I'm interested in using the uuid library for iphone development. Unfortunately, I can't use it "out of the box" because the function nil in uuid.hpp collides with the Objective C keyword of the same name and, hence, I get a compiler error. If I change the name to mynil, then it compiles ok. 1) Given this conflict, will you still proceed with the same function name? (As an fyi, all other boost libraries I've incorporated into the iphone fortunately don't have this problem.) 2) If so, do you have any suggestions on how I can handle this issue besides manually changing the function name from nil to something else? Thanks, Mostafa

[UUID] uuid.hpp ODR violation and Ctrl-M pollution
by Mostafa 25 Aug '09

25 Aug '09

Hi all, Using "uuid_alt_v13_pod.zip": 1) It seems that some namespace function definitions in uuid.hpp violate the ODR, specifically the ones lacking inline keyword. This is one of the errors I get using Apple's g++-4.0 when including uuid.hpp in two different source files: ld: duplicate symbol boost::uuids::operator>=(boost::uuids::uuid const&, boost::uuids::uuid const&) If I add inline to the aforementioned function definitions, then the linker errors go away, which makes since. After some digging around, this issue was discussed beginning with: http://lists.boost.org/Archives/boost/2007/05/122479.php but seems to have cropped back up. Examples are: "uuid/boost/uuid/uuid_io.hpp" and the files under "uuid/libs/uuid/test/"2) Also some files in the package are pseudo-randomly sprinkled with Ctrl-M characters, as if someone edited them with two different editors.. -Mostafa

A beta build of the docs for Boost-1.40 in PDF format is available from https://sourceforge.net/projects/boost/files/boost-docs/1.40.0/boost_pdf_1_… If folks can check their library's PDF docs for the usual SNAFU's that would be much appreciated (note only if your Boost library contains quickbook/boostbook/docbook format docs). Enjoy, John.

To be blunt though, Virtual Methods are not proper OO, multimethods are proper OO. C++ has been lacking in this, sometimes important area of OO, where things like LISP do wonderfully. Hmm, I know LISP has a well optimized multimethod implementation written in pure LISP, wonder how easily that method could be transferred to C++, although more verbose...
