mem_fn warnings
by David Abrahams 18 Mar '04

18 Mar '04

I keep getting lots of these: c:\boost\boost\mem_fn.hpp(264) : warning C4180: qualifier applied to function type has no meaning; ignored Would it be possible for the mem_fn header to #pragma push a warning disabler for MSVC? Thanks, -- Dave Abrahams Boost Consulting www.boost-consulting.com

RE: [boost] Trying to do something like boost::python for Netscap es SpiderMon key JavaScript engine
by Warrick Buchanan 18 Mar '04

18 Mar '04

Aaah and I've just noticed that boost::python uses the boost preprocessor stuff that I think does effectively through macros generate a load of templates for up to a constant N number of templated function arguments - and am I right in that this mad preprocessor stuff it recursively includes itself? eeek(!) -----Original Message----- From: Warrick Buchanan [mailto:Warrick@argonaut.com] Sent: 18 March 2004 10:44 To: 'boost(a)lists.boost.org' Subject: [boost] Trying to do something like boost::python for Netscapes SpiderMon key JavaScript engine Hi, As the subject says I'm trying to a boost::python like equivalent for SpiderMonkey (Netscape's JavaScript engine) and I've been trying(!) to look at boost::python for inspiration. I've got to the stage where I can quite happily expose a class like so: // D3D's Vector class just for example Declare<D3DXVECTOR>::Property<0>("x", &D3DXVECTOR3::x); // 0 is 'tinyid' Declare<D3DXVECTOR>::Property<1>("y", &D3DXVECTOR3::y); // 1 is 'tinyid' Declare<D3DXVECTOR>::Property<2>("z", &D3DXVECTOR3::z); // 2 is 'tinyid' Declare<D3DXVECTOR>::Definition("Vector3", jsContext, jsObject, jsPrototype); Just from those four lines you can then use the C++ class in JavaScript without issue ie: var v = new Vector3(); v.x = 4.0f; ...etc... Now I want to expose methods and constructors. Originally I was planning to have a load of templates for each number of arguments a function could possibly take (which obviously isn't ideal), but looking at boost::python it seems it has a more elegant but currently illegible to me way of doing this? Has anyone got any pointers to how this works or comments that would help my understanding?

Is there any interest in this container?
by Peter Palotas 18 Mar '04

18 Mar '04

I was wondering if there is any interest in a container that is a model of sequence (just like std::vector or std::list) and with an interface matching that of std::vector (maybe with minor differences due to effiency) but with different time complexities? Basically this is a Random Access Container but with the following time complexity guarantees instead: * insert/erase anywhere in the list: O(lg n) * element Access (i.e. [] or at()): O(lg n) * front()/back(): O(1) This would make it better than a list for random accessing elements and better than a vector for inserting/deleting elements in the middle of the list. I am currently working of an implementation of this container and thought I would see if there would be any interest in such a container from the boost community. Sincerely, Peter Palotas

64-bit IRIX build problems with Boost 1.31.0
by Patrick Hartling 18 Mar '04

18 Mar '04

I am trying to make a 64-bit build of Boost 1.31.0 on IRIX using the MIPSpro Compilers 7.3.1.3m, but I cannot seem to get any of the dynamic libraries to link. The bjam command line I am using is this: bjam -sTOOLS=mipspro "-sBUILD=debug release <runtime-link>static/dynamic <address-model>64" (I have $PYTHON_ROOT pointing to a 64-bit build of Python 2.2.3.) All link actions for dynamic libraries fail thusly: ld64: FATAL 12 : Expecting n64 objects: /usr/lib32//c++init.o is n32. Looking at the output after the failed action, I see -L/usr/lib32 in the link line, and I am pretty sure it should not be there. The complete output of the first failed action is this: "/usr/bin/CC" \ -o "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/libboost_date_time-mp-d-1_31.so" \ "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/greg_month.o" "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/greg_weekday.o" "bin/boost/libs/date_time/build/libboost_date_time.so/mipspro/debug/address-model-64/date_generators.o" \ \ "-DBOOST_DATE_TIME_POSIX_TIME_STD_CONFIG" "-DBOOST_ALL_DYN_LINK=1" \ "-nostdinc" "-LANG:std" "-OPT:Olimit=0" "-OPT:IEEE_NaN_inf=ON" "-no_auto_include" "-64" "-mips3" "-O0" "-g" "-INLINE:none" \ \ \ "-I/usr/include/CC" "-I//usr/include/CC" "-I/mnt/rigby/home13/users/patrick/src/Boost/blah/boost_1_31_0/boost/compatibility/cpp_c_headers" \ "-I/usr/include" "-I//usr/include" "-I/mnt/rigby/home13/users/patrick/src/Boost/blah/boost_1_31_0" \ "-nostdlib" "-shared" \ \ \ \ "-L/usr/lib32/mips3" "-L/usr/lib32/" "-L//usr/lib32/mips3" "-L//usr/lib32/" "-L/usr/lib32/mips3" "-L/usr/lib32/" "-L//usr/lib32/mips3" "-L//usr/lib32/" "-L/usr/lib64/mips3" "-L/usr/lib64/" "-L//usr/lib64/mips3" "-L//usr/lib64/" \ "-lm" All the object files being linked in this case are 64-bit, so I think that the compile action is behaving correctly. Am I forgetting something in my bjam command or otherwise misusing bjam? -Patrick -- Patrick L.

Hi, I am getting the following error. I see that it is trying to link to the static library, but I still get this error. Would appreciate if someone can correct my usage.

enumeration interface for boost::signals
by E. Gladyshev 18 Mar '04

18 Mar '04

Does boost::signals have a public enumeration interface (like iterator concept) that can be used for accessing individual slots? There is some mention of it in the "Slot Call Iterator" section but not much detailed. For instance, what I'd like is to call a slot and depending on the result call some other slot. A related question is if I have an instance of boost::signals::connection, is it possible to get an access to the slot that this connection is referencing? Thanks, Eugene
