boost::python and operator overloading
by srivatsan raghavan 16 Jul '02

16 Jul '02

hi all, i'm using boost::python to add acces to a C++ based network logging system from python and i'm running into a few snags wrt operator overloading .. specifically.. some of the classes support some operator signatures that i'm not sure how to export to python .. the python docs & boost::python discuss overloading operators, but only in the context of numeric extensions, and there is some things about a __coerce__ method .. but i'm not clear on how they should be used .. for example supports a stream-like interface: class LogStream { ILogStream& operator<<(long double ld); ILogStream& operator<<(std::string s); //for stream manipulators ILogStream& operator<<( ILogStream& (*pf)(ILogStream&)); } ; these are clearly not numeric operator overloads is there any way i can map these operators to their python equivalents ? --vat __________________________________________________ Do You Yahoo!?

noncopyable
by Volker Boerchers 16 Jul '02

16 Jul '02

Hi, to use boost::noncopyable I have to include boost/utility.hpp, i.e. _all_ utilities consisting of several template classes and functions. I expected to have a separate header in favour of compilation speed (as for boost/utility/base_from_member.hpp or boost/checked_delete.hpp which are included from utility.hpp). OK, at the end the preprocessed output is only ~100 lines (empty lines stripped) instead of 10 but what speaks against a separate header?

Boost Sockets
by James Zappia 15 Jul '02

Hi, Is there a boost library for network sockets on the radar? Most of the C++ socket libraries I've seen aren't very appealing. Just curious if boost will be offering something. Regards, James

problems w/ boost::regex
by srivatsan raghavan 12 Jul '02

12 Jul '02

i'm having some problems in trying to use boost::regex with msvc6 , sp 5 (using boost 1.28.0) jam generates some *.lib's & some *.dll's but when i try to compile code that trys to use regex (such as the examples ) , i get linker errors of the form ==> LINK : fatal error LNK1104: cannot open file "boost_regex_vc6_mssd.lib" Error executing link.exe. at first i was confused about this as i could not find any files with such a name .. after some grepping i found some explanations on the lib files that the regex headers use to figure out what lib to include (in boost\regex\detail\regex_library_include.hpp which is rather a neat way of doing things, but jam doesn't appear to follow that methodology .. so i'm stuck since the naming convenctions don't match, and i'm not sure what files jam is generating (in fact i'm not even sure that jam is generating the static runtime, static link versions of boost that the above error is requesting me to find .. --vat __________________________________________________ Do You Yahoo!?

RE: [Boost-Users] weak_ptr... no * or ->?
by Mark Storer 11 Jul '02

So the only purpose of a weak_ptr is to be able to grab a shared_ptr from it (and to avoid circular references, of course)? --Mark Storer Software Engineer Cardiff Software #include <disclaimer> typedef std::disclaimer<Cardiff> Discard;

weak_ptr... no * or ->?

Is there a reason weak_ptr doesn't have overloaded * and -> operators? --Mark Storer Software Engineer Cardiff Software #include <disclaimer> typedef std::disclaimer<Cardiff> Discard;

most recent thread_pool implementation?
by Niall Kelly 11 Jul '02

11 Jul '02

I've recently started using Boost and am working with 1.28.0 (modified to include the latest Boost.Signals from the CVS repository). I just obtained David Moore's thread_pool implementation from http://groups.yahoo.com/group/boost/files/thread_pool.zip and tweaked it slightly in order to build it with gcc 2.95.3 (no <limits>). I since noticed some more recent thread_pool source on CVS under boost/boost/libs/thread/src/Attic (bill_kempf). What is the purpose of the Attic subdirs? - unofficial work-in-progress type stuff or would I be better off using these versions of thread_pool? Also, is thread_pool likely to be included in the next official Boost release? Any idea when this might be? Finally, is a boost::xtime replacement likely to appear in the next release? Thanks for your assistance, Niall (Boost newbie) --------------------------------- SOLD.com.au- Find yourself a bargain! [Non-text portions of this message have been removed]
