Re: [Boost-users] Visual C++ 2005 help installing Boost

I am having exactly the same problem as a previous user. Could you please show me how you fixed your boost build? I'm getting the following errors ...failed updating 120 targets ...skipped 80 targets... ...updated 847 targets... I don't know how to open the vsvars32.bat file in order to change the paths that Mr Kozicki suggested. Any help would be greatly appreciated. I have installed the latest SDK. Also, how do i get rid of the warnings? I know i need to define _SCL_SECURE_NO_DEPRECATE globally, but how do i do that exactly? Finally, how do i know i have a correct build install? How do i test it? Thank you Please send your response to hgeorgako(a)hotmail.com harry g.

program_options' exception "Only one tab per paragraph is allowed"
by Peng Yu 16 Jan '07

16 Jan '07

Hi, I got the following exception thrown, when I have multiple tabs (boost 1.33.1). The code worked fine with boost 1.32.0. I'm wondering if there any specific reason to throw this exception in the newer version. If I need multiple tabs, are there any work around? Thanks, Peng terminate called after throwing an instance of 'boost::program_options::error' what(): Only one tab per paragraph is allowed Aborted

Ok! Instantiation On the Documentation it says: "...the header file export.hpp has to come after all the archive header files... in the Instatiation. And in the code of the file basic_archive.hpp it says: #error "export.hpp must not be included before any archive header" :S -- Miguel Silvestre

[boost.python][newbie], i can't compile with it
by Voph Devel 16 Jan '07

16 Jan '07

hello I'm entirely new to boost and also to python... For my first step I'm still having troubles for compiling my c++ code. just including <boost/python.hpp> leads my gcc to output these errors. g++ -O0 -g3 -Wall -c -fmessage-length=0 -oEnvPython.o ../EnvPython.cpp In file included from /usr/include/boost/python/detail/prefix.hpp:13, from /usr/include/boost/python/args.hpp:8, from /usr/include/boost/python.hpp:11, from ../EnvPython.h:4, from ../EnvPython.cpp:1: /usr/include/boost/python/detail/wrap_python.hpp:50:23: error: pyconfig.h: No such file or directory /usr/include/boost/python/detail/wrap_python.hpp:74:24: error: patchlevel.h: No such file or directory /usr/include/boost/python/detail/wrap_python.hpp:77:2: error: #error Python 2.2 or higher is required for this version of Boost.Python. /usr/include/boost/python/detail/wrap_python.hpp:141:21: error: Python.h: No such file or directory ( and then a thousand lines of errors...) I didn't manually build boost and boost.python. I'm running Debian, and I have the corresponding .so files for boost and python in my usr/lib. I have python 2.3 2.4 and 2.5 installed. pyconfig.h seems to be auto-generated. but i haven't a single clue for launching this ? do you know about my problem ?

Re: [Boost-users] Deriving Serialization classes
by Miguel Silvestre 15 Jan '07

15 Jan '07

???? a) But I'm deriving it from text_archive_imp b) what? I didn't understand.. As I said the binary serialization is working fine c) Onde again what do you mean?? How can I derivate the serialization classes?? I've tried the following code to, but with the same error: class TextArchiveO : public IArchive, // don't derive from text_oarchive !!! public boost::archive::text_oarchive_impl<TextArchiveO> { public: TextArchiveO(std::ostream & os, unsigned flags = 0) : boost::archive::text_oarchive_impl<TextArchiveO>(os, flags) {} ~TextArchiveO(){} virtual void Serialize(int& t) { *this & BOOST_SERIALIZATION_NVP(t); } virtual void Serialize(bool& t) { *this & BOOST_SERIALIZATION_NVP(t); } }; class TextArchiveI : public IArchive, // don't derive from text_oarchive !!! public boost::archive::text_iarchive_impl<TextArchiveI> { public: TextArchiveI(std::istream & is, unsigned flags = 0) : boost::archive::text_iarchive_impl<TextArchiveI>(is,flags) {} ~TextArchiveI(){} virtual void Serialize(int& t) { *this & BOOST_SERIALIZATION_NVP(t); } virtual void Serialize(bool& t) { *this & BOOST_SERIALIZATION_NVP(t); } }; On 1/10/07, Robert Ramey <ramey(a)rrsd.com> wrote: > > > > a) try deriving from text_?archive_impl rather than IArray > b) If you're going to put your own archive in a separate file - make sure you find > a way to explicitly instantiat it.

[bind] Overloaded function names
by Mark Ruzon 15 Jan '07

15 Jan '07

I have a function that performs the same task on several data types and data combinations: template <typename T> int f(const type1<T>& x); template <typename T> int f(const type2<T>& x); template <typename T> int f(const type2<T>& x, const type2<T>& y); I want to create a function object out of the second function. However, bind(f, _1) is ambiguous. Is there a way to disambiguate this using a bind call, or do I have to create my own function object? Thanks, Mark

[BGL] remove_edge with vecS for vertices and setS for edges
by Alejandro Marcos Aragón 15 Jan '07

15 Jan '07

Hi everyone, I was wondering if the library handles the edge removal for graphs that use the vecS as a container for the vertices and the setS for the edges. I've been trying to use the function and I have a segmentation fault. Thank you, a^2
