Q: BOOST.TEST VC7 mt gd worked on 1.30, fails on 1.31
by Dan Dimerman 16 Nov '04

16 Nov '04

Hello, I just wanted to ask about your experience with the latest (1.31) Boost.Test module. I had several unit tests written with Boost 1.30, and they worked fine. Now I upgraded to 1.31 and the unit test fails in a weird way: It seems to crash while DEALLOCATING the unit tests themselves. Call stack shows it fails on an ASSERT in <xmemory> void deallocate( pointer _Ptr, size_type ). Debugger shows that _ptr points to one of my unit test functions. I am linking with libboost_unit_test_framework-vc7-mt-gd-1_31.lib, libboost_date_time-vc7-mt-gd-1_31.lib, and xerces-c_2.lib (among others). Code generation: Multi-threaded Debug (/MTd). Any help would be appreciated... Thanks in advance.

install-name for OS X dylibs
by goochrules! 15 Nov '04

15 Nov '04

I was unable to find any reference to this on boost.org or in the mailing lists, so... Is there any way to specifiy the '-install_name' for ld to use when building boost for OS X? I see that currently the relative path to some sort of staging area in effect is used, for example, for libboost_thread-1_31.dylib, otool -L returns (among others): > otool -L libboost_thread-1_31.dylib libboost_thread-1_31.dylib: bin/boost/libs/thread/build/libboost_thread.dylib/darwin/release/shared-linkable-true/libboost_thread-1_31.dylib (compatibility version 0.0.0, current version 0.0.0) Alternatively, I suppose I could link the .o files (in $boost/bin/boost/thread/build/libboost_thread.dylib/darwin/release/shared-linkable-true/) manually; is there anything I should look out for if I choose this path? Are there any other object files I need to include? -- Matthew Peltzer -- goochrules(a)gmail.com

Boost and VC++: cannot open file 'libboost_date_time-vc71-mt-sgd-1_31.lib'
by Christopher Athaide 15 Nov '04

15 Nov '04

I have just started using the Boost libraries in VC++.NET - Please bear with me if this seems too simple. I am having trouble compiling this simple class library. //------------------------------------------------- #include "boost/date_time/gregorian/gregorian.hpp" #include "boost/date_time/date_parsing.hpp" namespace First { typedef boost::gregorian::date customDate; } //------------------------------------------------- I get the error message: "cannot open file 'libboost_date_time-vc71-mt-sgd-1_31.lib' " I saw the note by John Maddock and I tried to include this code at the start of the file but it did not help. // // Automatically link to the correct build variant where possible. // #if !defined(BOOST_ALL_NO_LIB) && !defined(BOOST_WHATEVER_NO_LIB) && !defined(BOOST_WHATEVER_SOURCE) // // Set the name of our library, this will get undef'ed by auto_link.hpp // once it's done with it: // #define BOOST_LIB_NAME boost_whatever // // If we're importing code from a dll, then tell auto_link.hpp about it: // #if defined(BOOST_ALL_DYN_LINK) || defined(BOOST_WHATEVER_DYN_LINK) # define BOOST_DYN_LINK #endif // // And include the header that does the work: // #include <boost/config/auto_link.hpp> #endif // auto-linking disabled Clearly I am missing something (maybe quite simple.) I appreciate any help in this matter. Thanks Chris

multi_array View vs. Subarray
by Kevin Bluck 15 Nov '04

15 Nov '04

With regard to boost::multi_array: Please, will somebody explain the difference between a View and a Subarray? I have read both the user and reference documentation, and can't find anything that indicates to me when you would use one over the other. So far as I can tell, they are essentially identical in purpose. Thanks, --- Kevin

boost bind question, can it create a functor with more arguments than needed
by gast 128 15 Nov '04

15 Nov '04

Dear all, Probably this is something one does not encounter often, but I have here an interface which expects more arguments than needed, e.g.: void SomeInterface(boost::function<void (Arg1, Arg2)> fcCallback) {} now I have another functor like: boost::function<void (Arg1)> fc; I want fc apply to SomeInterface, and it only needs to fill in argument1. So I need something like boost::bind(fc, _1, _2) to get it compilable for SomeInterface, only bind now thinks that fc has a prototype of two arguments. Is there a way to tell bind to ignore argument2 (without explicit write a functor)? wkr, me _________________________________________________________________ MSN Search, for accurate results! http://search.msn.nl

Hello, Little quick question, it isn't documented anywhere : The struct boost::xtime has a member called 'nsec' - what amount of time is this ? Thanks in advance! Leon Mergen

Can you use a template class to store data in a vertex of a boost graph?
by Stephen torri 15 Nov '04

15 Nov '04

Has anyone used a template class to store information in a vertex of a boost graph? I am looking for a way in which to store a variety of data types in a boost graph. So that if a sample class like following: template <typename T> class Data { ... }; It can be used to data such that a Data<int> and a Data<float> can be stored at a vertex in the graph. Is what I desire possible? Stephen

Newbie install on Mac: where are graph libs?
by Mike Fuller 14 Nov '04

14 Nov '04

I 'm having trouble installing the Boost graph libraries (release: boost_1_31_0) on my Macintosh laptop. I'm running Mac OS 10.3.6 on an iBook G4 (933 MHz), with 640 MB SDRAM and a 60 GB drive. gcc version 3.3 20030304 (Apple Computer, Inc. build 1666). Darwin Kernel Version 7.6.0. I followed the installation instructions provided in the html document: Getting Started (http://www.boost.org/more/getting_started.html) The procedure seemed to work smoothly: * The build script for Boost.Jam properly recognized the "darwin" toolset. * The command: bjam "-sTOOLS=gcc" install properly initiated the install script. * boost_python was not installed, but I didn't see this as a big deal since I don't use Python. However, when the build was complete, I could not locate the Boost graph libraries. I could only find eight types of Boost libraries in /usr/local/lib. (For each type, there are eight associated libraries, as is described in Getting Started.) I do not see the graph libraries. The boost libraries found after the build in /usr/local/lib include static and dynamic forms of: libboost_date_time-1_31 libboost_filesystem-1_31 libboost_prg_exec_monitor-1_31 libboost_regex-1_31 libboost_signals-1_31 libboost_test_exec_monitor-1_31 libboost_thread-1_31 libboost_unit_test_framework-1_31 Is the graph library not installed as part of the standard installation? Perhaps the problem is related to boost_python? Or are they installed somewhere else? Is there a separate procedure I'm missing? Thanks. I am not a UNIX super-user, and I don't have a lot of experience installing libraries. Please reply to mmfuller(a)tiem.utk.edu.
