erroneous use of BOOST_STATIC_CONSTANT ?
by Toon Knapen 14 Jul '04

14 Jul '04

When using BOOST_STATIC_CONSTANT, the member still need to be _defined_ in a .cpp file (IIUC 9.4.2 par 4 of the standard), unless the enum-trick is used, right? However gcc, intel-linux and the mipspro compiler (and probably others) do not require a seperate definition. OTOH IBM/VisualAge does really _need_ the definition (otherwise the symbols are undefined when linking). Would'nt it be better to advise library-developers to use an enum instead of BOOST_STATIC_CONSTANT if their library does not contain a definition? toon

The library fails to build so all the tests are marked as faile. Its my problem now. I'll be making a couple of small changes and we can try again. Robert Ramey

[preprocessor] sequence->initializer
by Vladimir Prus 14 Jul '04

14 Jul '04

Hello, support I have some Boost.Preprocessor data structure, say a sequence: #define SEQ ("1")("2")("3") how can I convert it into initalizer {"1", "2", "3"}? E.g: #define MY_TEST(SEQ) char* var = { SOMEHOW_GET_LIST_OF_VALUES(SEQ) } I've tried to look at preprocessor docs, but it's rather hard to find the answer. TIA, Volodya

question generated by serialization library build on Visual Age C++
by Robert Ramey 14 Jul '04

14 Jul '04

I'm getting a problem with serialization library build on IBM Visual Age compiler. It report that boost::iterator_difference<const char *> isn't complete. In perusing the code, it would seem to me that iterator_adaptor is including all it needs to resolve this and FWIW it works everywhere else. Can anyone give me a suggestion here? Robert Ramey "/home/tk/boost_regression/boost/boost/mpl/apply_if.hpp", line 39.5: 1540-0062 (S) The incomplete class "iterator_difference<const char *>" must not be used as a qualifier.

libs/iterator/doc/iterator_concepts.pdf not marked as binary
by Peter Dimov 14 Jul '04

14 Jul '04

libs/iterator/doc/iterator_concepts.pdf is not marked as binary in the CVS. The result is that it apparently has been scrambled at commit time, as neither a Windows nor a Linux check out a readable PDF. In addition, Windows always shows it as locally modified; my cvs commit just committed a new revision of iterator_concepts, but I didn't touch the file. I can't fix it because I don't have the original PDF, and cvs can't check out a working version. -- Peter Dimov http://www.pdimov.com

method deduction (on vc?)
by Max Khesin 14 Jul '04

14 Jul '04

I am working on some generic code that could use a method deduction trick of some sort. One mentioned by J.Maddock (http://lists.boost.org/MailArchives/boost/msg52178.php) does not work on vc6 - is there anything in boost (MPL?) that can help? Thanks, Max.

I will have to discuss this with my co-workers, but I think we will be able to deal with this -- by staying with one version for several boost release cycles. The real problem is that every new boost version brings interesting new features, and it's terribly hard to keep my hands off them ;-) -- Klaus
