Boost.ProgramOptions dynamic linking on mingw
by Alo Sarv 25 Jul '05

25 Jul '05

As noted at: http://engineering.meta-comm.com/boost-regression/CVS-HEAD/developer/output… progopt library fails to link on mingw as dll. After some searching around, I found out that using -Wl,--enable-runtime-pseudo-reloc flag during linking, it works properly. However, one should be warned that this flag should not be used when some of the code isn't compiled with the same compiler (e.g. mixing dlls/binaries from different compilers) - the resulting binary will always crash.

Why is this 8.3 conversion needed, It is a hack. To avoid having to modify the standard library (which doesn't support wide-character filenames), the 8.3 names are used instead. These appear to always be narrow even if the full name is wide. > can this work on NTFS reliable? Apparently not. I wasn't aware you could turn them off. >Replacing the current implementation thru a simple narrow conversion >helps as workaround. My understanding (which could be faulty) is that there is no general way to do such a wide to narrow conversion that always works. I'd love to be proven wrong. >- is_symlink() >Why isn't this function implemented on Windows? A NTFS junction is >symlink, isn't it? So I've been told. I tried a couple of times to figure out how to use junctions, but my eyes glazed over long before understanding occurred. >After fixing the above problems the library seems to run fine. > >Thank you for your work!

Re: [boost] Call for interest for native unicode character

Message: 2 Date: Sat, 23 Jul 2005 19:32:03 -0400 From: Ben Artin <macdev(a)artins.org> Subject: Re: [boost] Call for interest for native unicode character and string support in boost To: boost(a)lists.boost.org Message-ID: <macdev-DD69FE.19320323072005(a)sea.gmane.org> Dear Ben, Thanks for the reference, I have already taken a look at the previous posts. http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1040.pdf does mention the primitive types. I see that vector is a preference as a container - however I don't see any handling of graphemes, words, lines, and sentences which are integral parts on the Unicode 4 specification. Nor do I see any proposal for how to integrate the actual Unicode data which is vital to being able to implement Unicode iterators, sort, upper/lower case conversion, and the rest.... I have not seen anything on providing the necessary support for character information e.g. to convert logical to display order. This data even when optimised will still be several meg of data - but a Unicode implementation cannot fly without it. Nor do I see how you can ensure that if you base Unicode strings on vector that you can ensure that the contents is a Unicode string [e.g. adding the first member of a surrogate only and not adding the second member]. Has the conversation moved on? Where is this currently being discussed? Thanks. Yours, Graham Barnett BEng, MCSD/ MCAD .Net, MCSE/ MCSA 2003, CompTIA Sec+

Hello, I'm wondering how to assign or close a bug report on SF. Do I need special rights for this? If yes, can't we just give those rights to all boost members? Markus

Call for interest for native unicode character and string support in boost
by Graham 24 Jul '05

24 Jul '05

Hi, I am considering creating a set of Unicode support classes for boost that would add native Unicode support to boost and would like to find out if there is any interest in either using it or helping to write it. 1. unistring This would store UTF16 logically ordered data and allow Unicode actions and iterations. It would be largely similar the basic_string except the iterators supported would be forward only and would be arranged in the following class hierarchy: Data UTF16 - const iterator Grapheme Word Sentence Line Identifier Data: WORDs of data *Data Iterator: WORD UTF16: UTF16 encoded words [i.e. includes surrogates which are two WORDs] *UTF16 Iterator: const WORD Grapheme: What appears to the user as a character but may consist of several UTF16 encoded WORDs [e.g. e followed by acute]. *Grapheme Iterator: unichar Word: Word breaks [n.b. this would not work in languages like Thai where that cannot be computed from the characters]. *Word iterator: unistring [return portion of string as new and independent string] Line: Line breaks [n.b. ditto Thai ...] *Line iterator: unistring [return portion of string as new and independent string] Identifier: Language parsing iterator * Identifier iterator: unistring [return portion of string as new and independent string] All iterators would support basedata() which would convert the iterator to a Data iterator which can then have const cast off as required. The unistring would support equality (=) but not equivalence (<). Equality would perform canonical decomposition on the fly and compare decomposed data. Equivalence would be supported by a separate class called unistringsort. The following methods would be supported: empty size decompose tolower toupper assignUFT7 assignUTF8 assignUTF16 assignUTF32 insertUFT7 insertUTF8 insertUTF16 insertUTF32 find find_if replace replace_if others ... 2. unistringsort unistringsort would have two members, a const unistring and a const vector<WORD> of sort data [4 words per Unicode character]. Equality (=) would not be supported. Equivalence (<) would be supported which would do a level 4 compare on the sort data. Sort level 4 is the level used for display sorting of strings. Other levels allow ignoring case accents etc. The following methods would be supported: equals(const unistringsort & other, sortlevel level) would allow other sort levels (1, 2, 3, and 4) to be tested. const unistring& string() const vector<WORD>* data() Note: Unicode sorting is complex and involves sort decomposition, canonical decomposition, mathematical expansion of characters using a predetermined table and rules to 4 words per character that are then parsed in priority order. 3. unichar A unichar data type would also be created to allow Unicode tests on individual characters which will be DWORDs for ease due to the fact that Unicode characters are 21 bits. This would allow testing of: isstrongright isright isleft isstrongleft isleftjoining isrightjoining isbothjoining isnumeric etc... The implementation would require a few of Meg of data files created from the current Unicode release and my initial thoughts are that the following files would need to be parsed: allkeys.txt CaseFolding.txt GraphemeBreakTest.txt LineBreak.txt SentenceBreakTest.txt SpecialCasing.txt UnicodeData.txt WordBreakTest.txt The data files created would be header files containing native c arrays containing specially organised data to support all the above functionality. A program would be created to produce these files from the source automatically from an up to date Unicode release. The ranges in Blocks.txt would need to be hard coded to support functions like ishangul etc. Questions: 1. Is this worth doing are enough people interested to make it worthwhile? 2. Which would be the best implementation of basic_string to use? 3. Should unistring support equality due to the overhead in decomposition or should there be a decompunistring? 4. Do we need other classes or to include functionality such as the ability to convert to display order? 5. What other methods are required on the classes? 6. Any comments ?

[config] Possible bug in config/platform/win32.hpp
by Edward Diener 24 Jul '05

24 Jul '05

In config/platform/win32.hpp I see: #if !defined(__GNUC__) && !defined(BOOST_HAS_DECLSPEC) # define BOOST_HAS_DECLSPEC #endif This tells me that __declspec can be possibly used for all Windows compilers except for gcc. I believe, however, that for Comeau-Win32 __declspec can also not be used. When trying to build Boost libraries for Comeau with the VC7.1 backend, the compiler gives this error in the date/time library when trying to compile greg_month.cpp with BOOST_ALL_DYN_LINK defined: ""H:\Utilities\BoostLibraries\boost_1_32_0\boost/date_time/gregorian/greg_month.h pp", line 55: error #70: incomplete type is not allowed class BOOST_DATE_TIME_DECL greg_month : public greg_month_rep {" ^ I could be wrong but this seems to me that the compiler is objecting to BOOST_DATE_TIME_DECL, which becomes __declspec(dllexport) because BOOST_HAS_DECLSPEC is defined for the Comeau compiler. Needless to say many other errors along thr same lines occur in the build for other libraries which use __declspec(dllexport).

[OT] Mailinglist performance

Hi, I'm experiencing long delays between sending a message to this list and getting it back from the list (even a lot longer than the usual hour it took on good days). Also, messages from other people on the list arrive very late here and they often do not appear in the order they've been sent in. Looking at the traces left in the header of Joel's recent message, I see: Received: from 129.79.245.239 (EHLO milliways.osl.iu.edu) (129.79.245.239) by mta184.mail.re2.yahoo.com with SMTP; Sat, 23 Jul 2005 13:22:27 -0700 Received: from milliways.osl.iu.edu (localhost [127.0.0.1]) by milliways.osl.iu.edu (8.12.11/8.12.11/IUCS_2.66) with ESMTP id j6NI1TRS008999; Sat, 23 Jul 2005 13:02:39 -0500 (Note the different timezones.) This seems to indicate the message wasn't processed for two hours at OSL. Is there a problem at OSL? Regards, m Send instant messages to your online friends http://au.messenger.yahoo.com
