Who's Using Boost - Thankyou and updates
by John Maddock 14 Jun '05

14 Jun '05

Big thankyou to everyone who's responded to the "Who's Using Boost?" message, there is now an updated version of the web pages at: http://freespace.virgin.net/boost.regex/who/html/index.html Please do take a moment to check that your entry is correct, and if you haven't submitted an entry yet, why not ? :-> I hope to move this into cvs soon, but the question then becomes: before or after the release? Opinions on that welcome. Thanks, John.

fstream_test.cpp
by Jason Heyes 14 Jun '05

14 Jun '05

I receive errors when I try to compile fstream_test.cpp using Microsoft Visual C++ 6.0. The first error I receive is this: fstream_test.cpp c:\boost\include\boost-1_32\boost\filesystem\fstream.hpp(29): error C2504: 'basic_filebuf<char,char_traits<char> >': base class undefined c:\projects\examples\fstream_test.cpp(27): see reference to class template instantiation 'boost::filesystem::basic_filebuf<char,char_traits<char> >' being compiled Is there a workaround for this? Thanks. Send instant messages to your online friends http://au.messenger.yahoo.com

Build with ICU support
by Neal Becker 14 Jun '05

14 Jun '05

I have Fedora (pre-FC4). There are packages for icu: libicu, libicu-devel, libicu-doc which I installed. I can't seem to convince bjam to use them. What do I need to do? Headers are in /usr/include/unicode (e.g., /usr/include/utypes.h). Libs are rpm -ql libicu /usr/lib64/libicudata.so.32 /usr/lib64/libicudata.so.32.0 /usr/lib64/libicui18n.so.32 /usr/lib64/libicui18n.so.32.0 /usr/lib64/libicuio.so.32 /usr/lib64/libicuio.so.32.0 /usr/lib64/libicule.so.32 /usr/lib64/libicule.so.32.0 /usr/lib64/libiculx.so.32 /usr/lib64/libiculx.so.32.0 /usr/lib64/libicutu.so.32 /usr/lib64/libicutu.so.32.0 /usr/lib64/libicuuc.so.32 /usr/lib64/libicuuc.so.32.0

Category: random Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Jens Maurer (jmaurer) Summary: binomial_distribution.hpp Initial Comment: binomial_distribution gives wrong results, because ctor only default initializes private member _bernoulli, therefore probability is always p=0.5 (the default of bernoulli_distribution). Solution: put _bernoulli(p) into the initializes list of binomial_distribution ctor.

Towards a Boost.Network proposal
by pedro.lamarao＠mndfck.org 14 Jun '05

14 Jun '05

Fellow Boosters, to spice up a bit the discussion about networking IOStreams, and to try and bring more of you into a fruitful discussion, I've uploaded a (or, one more ;-) "network" library to the Sandbox. The file is called network.tar.bz2 (duh) located in the pedro_lamarao folder. The layout of the archive is the familiar boost directory layout, ready to be expanded on top of a boost release. It was worked on a 1.32 version of boost. Every new name was added into a boost::network namespace. Every file is licensed under the Boost License; but please note I'm currently employed, and haven't talked to my employer yet about copyright assignments. I plan to initiate a conversation with them to secure the copyright for this code as soon as possible. BoostBook documentation is provided with a Jamfile.v2 for bjam, but with much to fill in many sections. I still don't totally get the documentation build process, but had success in moving to libs/network/doc and calling bjam --v2 to build the html files. Examples are provided in subdirectories of the libs/example/ directory, each with a Jamfile for bjam. These examples are still far from what I think is possible to achieve, but already show some interesting coding patterns facilitated by the IOStream interfaces. The implementation is as simples as it gets with regards to performance. With regards to the IOStream classes, much is left to the default implementation of the standard library. But the code is fully usable, as can be determined by running the provided examples. Also, I'm unsure I finished all aspects of the Windows implementation. I don't have access to a Windows development environment from home. In the next days I'll concentrate in writing proper documentation. All this is to try and attract the attention of the average programmer with common needs for a C++ networking library, and to learn what those kinds of needs are; my only clue in this regard comes from my previous contact with your typical Internet protocols like SMTP, FTP, and the like. As it will be quickly evident, the design and implementation of this library does not address the complex requirements set in the networking discussion in the Boost Wiki. This implementation's purpose is to be useful to it's audience, right here, right now. -- Pedro Lamarão

I'm probably being dense, but what is the connection between ar >> rhs not working because rhs is a function call, and ar << rhs where rhs is a function call, in the case that load and save are split? If it's a temporary int on the stack, what's the complexity? Also, how is the library "detecting" that I'm doing ar << foo();, and then failing during compilation, rather than ar << x;?

MPL on IBM-vacpp
by Toon Knapen 14 Jun '05

14 Jun '05

As you might have noticed we have succeeded in running regression.py on IBM. In the mean time Joaquin already noted that multi_index was broken. He also suggested that it was probably due to BOOST_MPL_CFG_USE_OPERATORS_OVERLOADING. And indeed, adding BOOST_WORKAROUND(__IBMCPP__, <= 600 ) to boost/mpl/aux_/config makes that multi_index compiles again (and probably other libs too). So is it OK to add the patch in attachment ?

Zetec loves boost
by Thomas Matelich 14 Jun '05

14 Jun '05

Application: Eddynet Suite (ZAC, Electronic Resolution, EIMS-[BOP,SG,TSB], and more) Company: Zetec, Inc. Product Description: Eddynet is a complete suite of software for conducting an eddy current inspection of metal tubing, especially that in steam generators of nuclear power plants. We've been using Boost since 2001 in our C++ rewrite of our legacy systems. Boost libraries used: Smart Pointer - shared_ptr has made life good Utility - I love noncopyable Bind - The most fun way to confound my coworkers. Graph - This library and the makefile dependencies example was a godsend for creating a build & link management/subset creation/circular dependency check tool for our 110 cvs modules. Iterator Cast: lexical_cast and numeric_cast Function Regex Tuple - great for when you're too lazy to make a struct Lambda - so much fun! Ref Static Assert Type Traits Quaternion Any Format Tokenizer TriBool CRC Operators Product webpage: http://www.zetec.com/industries/energy/sg_software.asp (We're hiring, boost experience preferred :)
