boost & STLport
by François Dumont 20 Jul '04

Hello boosters I am trying to build boost 1.31.0 with STLport 5.0 RC1 using MSVC 6 SP5. I already spend quite a long time on a very mysterious issue with no result, I hope you will be able to help me. When I build the boost libraries I have the following error messages: vc-C++ bin\boost\libs\filesystem\build\libboost_filesystem.lib\msvc-stlport\debug\s tlport-iostream-on\exception.obj exception.cpp C:\PROGRA~1\MICROS~4\VC98\include\objidl.h(9909) : error C2668: 'memset' : ambiguous call to overloaded function C:\PROGRA~1\MICROS~4\VC98\include\objbase.h(443) : error C2668: 'memcmp' : ambiguous call to overloaded function C:\PROGRA~1\MICROS~4\VC98\include\objbase.h(467) : error C2668: 'memcmp' : ambiguous call to overloaded function "cl" /Zm800 -nologo -GX -c -D_STLP_DO_IMPORT_CSTD_FUNCTIONS=1 -D_STLP_DEBUG=1 -D _STLP_DEBUG_UNINITIALIZED=1 /Z7 / Od /Ob0 /GX /GR /MDd -I"bin\boost\libs\filesystem\build" -I"C:\Utils\boost_1_31_0" -I"C:\ Utils\STLport-5.0.0\stlport" -I"C:\Utils\boost_1_31_0" -I"C:\PROGRA~1\MICROS~4\VC98\include" -Fo"bin\b oost\libs\filesystem\build\libboost_filesyst em.lib\msvc-stlport\debug\stlport-iostream-on\exception.obj" -Tp"C:\Utils\b oost_1_31_0\libs\filesystem\build\../src/exc eption.cpp" This only happen during boost build process with STLport 5.0. When I use both boost and STLport 5.0 in a simple test that call memset there is no ambiguity. Is there any special treatment within boost code for memset and memcmp? I also notice, looking at the command line, that STLport include path is not first. Is there a special reason not to have it first? If I want to test how can I make it first? Bests

[patch] minor docs clean up
by Jonathan Wakely 20 Jul '04

20 Jul '04

Hi all, The attached patch fixes several trivial spelling and markup errors, mostly in HTML files, that I came across while reading. It also updates the comment about DR 214 in libs/bind/bind.html, since that DR has been moved to WP status and is on the cwg_defects page, not cwg_active. Is it premature to say it's been "resolved" in the comment? Should the hostname for the defect list be changed to www.open-std.org as well? I assumed it should be. Affected files: libs/bind/bind.html libs/config/configure libs/date_time/doc/DesignGoals.html libs/date_time/xmldoc/date_time_autodoc.boostbook libs/date_time/xmldoc/design_goals.xml libs/filesystem/src/exception.cpp libs/program_options/doc/rationale.dox libs/regex/doc/match_flag_type.html libs/serialization/doc/archive_reference.html libs/serialization/doc/headers.html libs/serialization/doc/serialization.html libs/serialization/doc/traits.html libs/signals/doc/rationale.xml libs/test/src/supplied_log_formatters.cpp libs/test/src/test_tools.cpp I don't have write access, so if anyone cares whether these are fixed before the next release they'll have to commit them themselves. Jon T. Pedant P.S. while I'm being pedantic, has anyone else who owns a copy of the hardback ISO 14882 book, published by Wiley, noticed that one of the signatures* is bound upside down? * "Signature" meaning a bundle of paper folded together and bound to to other signatures to form a book. Have I got the right term? -- "Strange how potent cheap music is." - No�l Coward

Boost.test: minor fix
by Vladimir Prus 20 Jul '04

20 Jul '04

I've took the liberty of comitting the following change, which make "m_value" visible on compilers with two-phase lookup (like gcc 3.4) However, the token_iterator_test still fails to compile on 3.4 saying: token_iterator_test.cpp:47:38: converting to execution character set: Invalid or incomplete multibyte or wide character token_iterator_test.cpp:48:31: converting to execution character set: Invalid or incomplete multibyte or wide character token_iterator_test.cpp:48:42: converting to execution character set: Invalid argument token_iterator_test.cpp:48:49: converting to execution character set: Invalid argument token_iterator_test.cpp:48:55: converting to execution character set: Invalid or incomplete multibyte or wide character Looks like the text in L"" literals is not 7-bit, and that's why compiler errors out. Is it possible to change the test somehow? - Volodya Index: token_iterator.hpp =================================================================== RCS file: /cvsroot/boost/boost/boost/test/detail/iterator/token_iterator.hpp,v retrieving revision 1.3 diff -u -r1.3 token_iterator.hpp --- token_iterator.hpp 19 Jul 2004 12:29:57 -0000 1.3 +++ token_iterator.hpp 20 Jul 2004 12:45:47 -0000 @@ -309,7 +309,7 @@ typedef ut_detail::token_assigner<BOOST_DEDUCED_TYPENAME iterator_traversal<Iter>::type> Assigner; Iter checkpoint; - Assigner::clear( m_value ); + Assigner::clear( this->m_value ); if( !m_keep_empty_tokens ) { while( begin != end && m_is_dropped( *begin ) )

So what course of action do you recommend? Also, as I understand the problem, If I don't use tmpnam but just assign a fixed name like "xyz", the same issues re race conditions and potential flaws are still present - are they not? This is sort of an interesting question but seems way beyond the scope of what can be addressed by a program whose function is to test a library during development. Perhaps you want to conjure up a definitive solution and submit for consideration as part of the filesystem library. Robert Ramey

So I'm going to: >1. put new header to boost/detail >2. put new source to libs/detail/utf >3. #include new source in program_options. Fine. I'll #include new source in serialization as well so we'll all be in the same page. Question. Does this not mean that this if an application includes both the serialization package as well as the program options package that some linkers will fail to links with a duplicate symbol message? I would also like to see 1. The documentation page and test moved to a neutral spot. 2. Could you examine my version and your version and reconcile any differences. Given Rene's observations, I made a pass and fixed the issues he mentioned. It's a could of changes but they are small and make things much more transparent and reliable. I've also tested them on a variety of compilers and feel much better about it. Robert Ramey

Boost.Thread fix for gcc 3.4
by Vladimir Prus 20 Jul '04

20 Jul '04

The test_thread test fails on g++3.4 on this line: BOOST_TEST(thrd == boost::thread()); saying that copy constructor of boost::noncopyable is not accessible. My understanding of the problem is that boost::thread() is rvalue. According to standard, implementation - bind reference to rvalue - create temporary the copy constructor, however, should be accessible no matter what implementation decides. Earlier gcc version did not enforce this rule, apparently. I've comitted the attached obvious fix, tested to work on 3.4, 3.3, 3.2 and 2.95. - Volodya

missing jam_log.xml
by DY, JERRY U (SBCSI) 20 Jul '04

20 Jul '04

The test results being generated on HP-UX-PARISC looks different than everybody else's. Not sure if it's related, but I also get the following messages towards the end of the testing: Missing jam_log.xml in target: /pics/log/ccase/boost/boost/bin/boost/libs/utility/test/binary_search_te st.test/acc/debug Missing jam_log.xml in target: /pics/log/ccase/boost/boost/bin/boost/libs/utility/test/checked_delete_t est.test/acc/debug Missing jam_log.xml in target: /pics/log/ccase/boost/boost/bin/boost/libs/utility/test/result_of_test.t est/acc/debug and indeed I don't find jam_log.xml anywhere. Who generates this file? This is not the same as test_log.xml, is it? Thanks! -Jerry

algorithm/string/iterator_range: copy-construction from singular iterator
by Guillaume Melquiond 20 Jul '04

20 Jul '04

Hi, Almost all is said in the subject. According to 24.1-5 it is undefined behavior; consequently default initialized parameters cannot be used. So here comes a patch. I didn't put the half constructor (only a "begin" parameter, no "end" parameter) because I don't think it makes sense; but if it does, just add it. Regards, Guillaume
