[RC_1_34_0] MSVC 8.0 link looking for lib*
by Dean Michael Berris 02 Jul '06

02 Jul '06

Hi Everyone, The headers are being copied now, but the linking of unit-test targets are looking for "libboost_unit_test_framework-vc80-mt-gd-1_34.lib" when the library built and installed was "boost_unit_test_framework-vc80-gd-1_34.lib" In user-config.jam, the following line defines the toolset used: using msvc : 8.0 ; I certainly hope this helps -- and I'm still clueless how to diagnose this without a deeper understanding of the boost build system. Pointers would be most appreciated. Have a great day everyone! -- Dean Michael C.

[RC_1_34_0] Boost Build v2 installation missing headers
by Dean Michael Berris 02 Jul '06

02 Jul '06

Hi Everyone, I'm sending a ping again regarding the installation target of Boost Build v2. I ran this command (on RC_1_34_0) and noticed some headers weren't being copied over: bjam --v2 install --prefix="C:\Program Files\Microsoft Visual Studio 8" I am trying to build the library I'm working on ( http://sourceforge.net/projects/dispatcher ) using MSVC 8. I've not enough experience with Boost.Jam (I just had it up and running, and my local copy of the library was just converted to build against/with boost using Boost.Jam) but would like to see how I can check which headers are being copied over for msvc. Most of the missing headers that I noticed pertained to msvc specific headers (like detail/msvc in preprocessor, and mpl). Is there a place where I should start looking? Ive tried most of the .jam files in the boost/tools/build directory, but somehow I don't feel like I'm looking in the right place. I really would like to help, though pointers would be most appreciated. Have a great weekend everyone! -- Dean Michael C.

bbv2 bison/yacc windows unistd.h - Build Problems
by Roland Schwarz 02 Jul '06

02 Jul '06

I am trying to build the boost library from cvs HEAD, using bbv2. The problem platform is windows. (On linux everything works ok.) I've noticed that bbv2 uses more tools than bbv1 did. I.e. the bison/yacc within the graph library. So I installed bison, but during build, when the compiler tries to translate the file built by bison, it does not find unistd.h. This file is not available in the standard include path of the compiler used (msvc-7.1) but in a subdirectory of the bison path. How can I now tell bbv2 to use this directory? Sorry if my question sounds silly, but I am still rather new to bbv2. I guess I'd need to tweak site-config.jam? If yes what shall I put in there? Thank you for help. Roland

[iostreams] One test fails for Metacomm, not for me
by Nicola Musatti 01 Jul '06

01 Jul '06

Hallo, I'm a bit puzzled by the failure of the compose_test test, which shows up in the current Metacomm results. I'm using BBv1 for running my tests, while I would guess that the Metacomm people are using BBv2. Still the generated command lines appear very similar, the only differences being the use of absolute paths and the explicit reference to the standard include directory in the Metacomm command line. I wonder if there's any configuration mismatch, like the use of different kinds of libraries (e.g. static vs. dynamic?). I'm checking to see if there are other diverging results. It would be interesting to know what other Borland users get from running the tests. Cheers, Nicola Musatti

Interest in a flyweight library?
by Joaquín Mª López Muñoz 01 Jul '06

01 Jul '06

During some conversations with a colleague I came up with a very sketchy realization of what could be converted, if there is interest, in a flyweight library. Please see flyweight.hpp at Vault/Patterns: http://tinyurl.com/l6lt4 The so-called Flyweight Design Pattern, upon which this is inspired, is much too OO for current C++ tastes IMHO, what I'm proposing takes a more generic stance. A minimal use example follows showing the syntax: #include "flyweight.hpp" #include <string> #include <iostream> int main() { using boost::flyweight::flyweight; flyweight<std::string> str("hello world"); std::cout<<str<<"\n"; } Briefly put, a flyweight<T> is an object that can be used as a const T (i.e. flyweight<T> provides an operator const T&) but whose size is that of a pointer. The trick is that identical flyweight<T> objects share their representation globally, which drastically reduces memory usage when there are much more objects than different values. Additionally, comparison of flyweight objects can be made faster than that of the underlying type T, since we it reduces to pointer comparison --contrast that with what takes to compare the underlinyg type T when T=std::string, for instance. So, is there interest in having such a lib in Boost? Please note that the provided implementation is still a primitive one, but OTOH it does have all the advertised functionality, so one can use it to test it locally and form an opinion about its suitability: if somebody, for instance, can plug it into some scenario with massive quantities of elements, I'd appreciate knowing about resulting memory and performance improvements. In case this raises interest, I can turn the thing into a more fleshed out proposal during the summer. Thank you for your attention, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Would you care to submit your name proposal in the aforementioned format? Although I haven't said it before, it'd be good if the namespace did *not* coincide with that of the main utility, since it can lead to problems as descibred in http://boost.org/libs/tuple/doc/design_decisions_rationale.html in connection with the choice of namespace tuples instead of namespace tuple. > Another question, C# and some other languages have the idea of > 'boxing' -- perhaps that's what this really is? I don't think so. From my limited knowledge of Java and C#, where this term is used, boxing consists of the procedure by which a stack-based type is wrapped into a heap-based type so that it can be used in certain contexts: for instance, in Java ints cannot be used in containers so one has to box them in java.lang.Integer's. There's a weak connection with my proposal in that (at least in Java) these numeric wrappers are immutable and as such candidates for flyweighing techniques. Is this what you were referring to, perhaps? > Jeff [One final question you didn't address: do you think this worth elaborating into a proposal for Boost?] Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Thank you for your enthusiasm :) I'm afraid it'll take me weeks to come up with something complete enough to apply for a review. But given that there's quite some interest, I think I'll put myself to work on it. > As others have noted, of all the languages I have looked at, I've > never heard the term "flyweight", only "interned". Where does > "flyweight" come from? This library might get more recognition if > it used the more common name. As I said in other of my responses, I'd appreciate your proposing names according to the format lib name / namespace names / main utility so as to be able to compare among alternatives. Thank you!
