Run-time problem with VC6, stlport and boost (1.32) regex
by Mats Lidell 17 May '05

17 May '05

Hi, I'm getting this runtime error in my program. c:\stlport-4.6.2\stlport\stl\debug\_iterator.h(179): STL assertion failure : __check_same_owner(__x, __y) The code that causes this is like this (Actual code slightly modified). It is the access of the match that triggers the error above. boost::smatch m; if (regex_match(s, m, reg)) { (here)--> s_info.version = m[1]; } I'm using stlport 4.6.2 with boost-1.32 on W2K and VC6 SP6. stlport is built with default options and boost is built like this: boost-jam-3.1.10-1-ntx86/bjam.exe -sTOOLS=msvc-stlport -sSTLPORT_PATH="c:" -sSTLPORT_VERSION=4.6.2 -sBUILD="debug release <runtime-link>static <threading>multi <stlport-iostream>on" install Any idea what can be wrong? Surely a simple access of the resulting match shouldn't cause this type of assertion to fire (or is there some subtle bug in my program that I'm missing!?) Please note that the program works OK using boost without stlport. Yours -- %% Mats

fatal error C1204 on MS .Net with boost serialize
by Olivier Vanden Bos 17 May '05

17 May '05

I ve got a lot of this, i m forced to split all declarations of classes in separate .cpp file. In fact, Boost::serialize become unusable... Does somebody have a solution ? - VDB - "LNK2019: unresolved external symbol" Olivier Vanden Bos MSN#TheVdeub(a)hotmail.com AI Programmer UBISOFT Montreal

boost.serialization crash
by Eyal Susser 17 May '05

17 May '05

Hi, I was using the boost.serialization library to my great satisfaction on an intel machine running Linux. I then ported the code to a MIPS machine. I compiled boost using bjam with a mips compiler that isn't included in the available toolsets. Everything works well _until_ I try destroying the binary archives I use. When the destructor is called, I get a segmentation fault. My guess is that the serialization library relies on something else which wasn't compiled properly. But what? I built boost as follows: bjam -sTOOLS=gcc -sGXX=/usr/mips/bin/mips-linux-g++ --libdir=/usr/mips/lib/ --includedir=/usr/mips/include/ -sGCC_ROOT_DIRECTORY=/usr/mips install I have a lib directory and an include directory under /usr/mips. While building boost I got a whole bunch of errors, and not all the targets were successfully built, but I had no idea what to do, so I tried anyway... Thanks

[spirit] parse(iter,iter,rule)
by Thorsten Ottosen 16 May '05

Hi Shouldn't it be possible to parse with the following syntax: std::string text( "fooooo"); static rule<> r = *space_p >> '"' >> (*alnum_p)[assign_a(name)] >> '"'; parse_info<std::string::const_iterator> info = boost::spirit::parse( text.begin(), text.end(), r ); How do I otherwise interpret http://www.boost.org/libs/spirit/doc/scanner.html ?

[Signals] Observation about performance
by Keith MacDonald 16 May '05

16 May '05

I have an application that implements the Observer pattern, based on the GOF code and was interested in using Boost.Signals in a new application. Before committing myself, I decided to check the relative performance when signalling two observers. Both tests were performed on Windows XP, using MSVC 8 beta 2, with the /Ox optimisation. Here are the times for 6,000,000 signals, measured with the Win32 GetTickCount() API on a 3GHz P4 with 1GB RAM: GOF Observer: 109 Boost.Signals: 6203 Clearly, you have to trade convenience for performance with this library. - Keith MacDonald

Declaring boost.serialization archivers as members
by Eyal Susser 16 May '05

16 May '05

Hi, After doing what I described in the subject, I found that when marshalling data between processes, the same data gets sent over and over again. It's as if the archiver has some internal copy of the stream, and keeps serializing that stream over and over. Anyone else have this problem, or is it some pitfall in my implementation? Thanks

Compiler status table for Boost v1.32?
by Moore, J. David 16 May '05

16 May '05

Hello, I am interested in seeing the compiler status page for the 1.32 release of Boost. I was able to follow links on www.boost.org to see the compiler status for the head of the cvs repository: http://www.meta-comm.com/engineering/boost-regression/CVS-HEAD/developer /index.html, However, I could not find information for previous releases. Is this information archived anywhere? Thanks, Dave Moore IMPORTANT: The information contained in this email and/or its attachments is confidential.

numeric conversion lib documentation

The docs for the converter class are missing descriptions of the two most important template parameters, T and S. http://www.boost.org/libs/numeric/conversion/doc/converter.html Cheers, Jeremy _______________________________________________ Jeremy Siek <jsiek(a)osl.iu.edu> http://www.osl.iu.edu/~jsiek Ph.D. Student, Indiana University Bloomington C++ Booster (http://www.boost.org) _______________________________________________

Can boost::threads be started in detached state ?
by Shetty, Diwakar 16 May '05

16 May '05

Hi, I am using boost:thread. There does not seem to be any constructor which specifies whether the thread can be started in detached state. Will I have to use the native OS threading calls to do this? Thanks, Diwakar
