test boost-1.33 srpm
by Neal Becker 12 Aug '05

12 Aug '05

I placed my test boost-1.33 srpm here: http://nbecker.dyndns.org:8080/boost-1.33.0-6.src.rpm Basically, I modified the redhat 1.32 spec file: 1) Don't mess with soname 2) Autoconfigure icu support 3) Build all variants 4) Add my (little) patch for serializing mersenne_twister. Yes, I know it's not optimal, but it's simple and good enough for my purposes. Please comment.

[Config][auto_link] BOOST_LIB_TOOLSET override does not work as intended when multiple libraries are used
by Sean Huang 12 Aug '05

12 Aug '05

For example, if BOOST_LIB_TOOLSET is defined as "iw90" and both thread and signals libraries are used in a cpp file, compiler prints out the following: Linking to lib file: libboost_thread-iw90-mt-s-1_33.lib Linking to lib file: libboost_signals-iw-mt-s-1_33.lib The problem is caused by BOOST_LIB_TOOLSET being undefined at the end of auto_link.hpp. The second time auto_link.hpp is included (it has no include guards and is meant to be included multiple times) BOOST_LIB_TOOLSET is not defined anymore and a default value will be assigned. Does it really need to be undef'ed? Thanks, Sean

[test] basic_cstring_test errors
by Markus Schöpflin 12 Aug '05

12 Aug '05

basic_cstring_test currently fails to compile on the latest pre-release version of HP's cxx compiler. The following sample illustrates the problem: template <typename T> static void foo(T * t) { } template <typename T> void func() { foo((T *) 0); } // (*) int main() { func<int>(); return 0; } The call to foo at (*) doesn't find the declaration for foo because dependent name lookup for functions referred by an unqualified id only finds functions with external linkage. (See 14.6.4.2) A possible fix is to remove the static from the declaration of foo. Applied to basic_cstring_test, this would mean to remove the static from the declaration of test_string(). Markus

Confused about threading
by Neal Becker 12 Aug '05

12 Aug '05

I started out by trying to figure out if shared_ptr always uses threading. A quick look at the jamfiles did not suggest that threading was disabled when building single. Then I tried this: nm --demangle libboost_regex-d.a | grep -i thread [ lots of threading symbols ] OK, so why is the single threaded version of a library full of threading references? Is this a problem? Oh, this is gcc/linux system

[thread] assertion error when exiting app
by Felipe Magno de Almeida 12 Aug '05

12 Aug '05

Hi, I'm having an assertion failed when trying to finish my application. I use Boost.Thread to create one thread and use serialization and spirit that I know use threads either. It wasnt happening when using an earlier boost cvs version... And for some reason I'm not being able to debug it, when trying to the app finishes when reaching the MSVC. I'm using MSVC 7.1 and the assertion is: File: boost-path\libs\thread\build\..\src\tss_hooks.cpp Line: 131 Expression: attached_thread_count == 0 This application uses different threads to create and destroy objects throughout its lifetime(probably even the static/singleton objects). It is an COM object and is accessed through "RPC", where the creation of the singletons takes place... If anybody has any clue to what it could be, I would really appreciate. I'm going to update my boost to the RC2 and see what happens. Thanks in advance, Felipe. -- Felipe Magno de Almeida Developer from synergy and Computer Science student from State University of Campinas(UNICAMP).

regression on aix
by Toon Knapen 12 Aug '05

12 Aug '05

This week we upgraded our VisualAge compiler from 6.0.0.8 to 6.0.0.13 (because of problems with the preprocessor) which is the latest PTF (which is ibm speak for 'service pack'). We will thus also use this updated version to run the regression tests during the weekend (which are reported here: http://tinyurl.com/bms8v) However we will have *many* regressions because of compilation problems in some headers that are (indirectly) used in many places. For instance one problem is the gcc_3_2_wknd struct in mpl/has_xxx.hpp (see attached compiler error report). I fiddled around a bit with it and I do not understand why the compiler reports gcc_3_2_wknd to be an incomplete class. I also noted that defining gcc_3_2_wknd outside of the trait struct works. But this solution is also problematic from the moment the BOOST_MPL_HAS_XX_TRAIT_NAMED_DEF is used twice in which case the gcc_3_2_wknd will be defined twice ;-( Any suggestions are welcome! warning: Python location is not configured warning: the Boost.Python library won't be built Building Boost.Regex with the optional Unicode/ICU support disabled.

It seems to me that embedding links in continous text in a way that is a) easy to ignore when you are reading the text and b) easy to find when you are looking for the link, is essentially a hard problem. I would argue that Beth has got about as close as we are going to get (although I believe Rene objects to underlines). It WOULD be really nice to get this in to 1.33, but on the other hand I am not sure we have a consensus yet AND it is awfully late in the day to be making /any/ changes to the release. Final question: How do we go about establishing if we have a consensus or not so that we can at least update the main boost website? (Even if we can't include in 1.33). -- Martin Bonner Martin.Bonner(a)Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 441434
