[statechart] trunk regression test failures
by Richard Webb 06 Apr '08

06 Apr '08

Some of the statechart tests (e.g. http://tinyurl.com/56o53l) are failing with errors about boost::function. e.g. fifo_worker.hpp(70) : error C2977: 'boost::function0' : too many template arguments. Looks like the failures are due to the recent change in allocator support in the function library (http://thread.gmane.org/gmane.comp.lib.boost.devel/171585) Thanks, Richard Webb

async_read_until and \0
by Billy Chasen 06 Apr '08

06 Apr '08

Hello, I'm creating a server using boost:asio and am receiving data that ends with a \0 char (from flash sockets if you're curious) async_read_until seems to not like this as the delimiter. (If I switch to a diff delim like \r\n it works fine) How can I get async_read_until to work properly? thanks, billy

[shifted_ptr] Documentation roots
by Phil Bouchard 05 Apr '08

05 Apr '08

Greetings Boost: I have uploaded a new version having minor fixes but I have also included some basic documentation describing the shifted_ptr internals. The former API reference doc has moved to its given "api" subdirectory. I apologize for the non-standard format of the documentation files; this is temporary. There isn't much left to be done on the functionality side of the project besides adding pool allocation for internal objects. Let's put an end to that application crash era: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filenam… Regards, -Phil

[svn] user-config.jam
by Steven Watanabe 05 Apr '08

05 Apr '08

AMDG Revision 44023 made some unintentional changes to user-config.jam. Some but not all were fixed in 44024. Can the xsltproc and boostbook configuration be removed, too? In Christ, Steven Watanabe

'bjam install' documentation on "Getting Started on Windows" page
by Dave Compton 05 Apr '08

05 Apr '08

Is it necessary to run the 'bjam install' after building boost from source? I always do this but have never been sure if it is needed. The reason that I am asking is that the 'Boost Getting Started with Windows' page does not say anything about it and probably should if it is necessary.

[config] BOOST_DISABLE_THREADS defined by Boost.Config
by Peter Dimov 05 Apr '08

05 Apr '08

Joe Gottman quite correctly points out in http://svn.boost.org/trac/boost/ticket/1762 that shared_ptr should honor user definitions of BOOST_DISABLE_THREADS and disable MT support. Unfortunately, despite documenting quite clearly that BOOST_DISABLE_THREADS is a user macro, Boost.Config defines it in some situations. This means that I can't rely on this macro to reflect the user's intent, as I don't know whether it's been set explicitly by the user, or implicitly (and incorrectly IMO) by Boost.Config.

ARM platform: undefined reference to __sync_fetch_and_add_4
by Rob Desbois 04 Apr '08

04 Apr '08

I cannot link against Boost libraries 1.35.0 built with CodeSourcery's ARM/GNU toolchain, although the build is successful. I built Boost with: bjam --with-regex --with-serialization --with-thread stage And tried to link to the test program from the 'Getting Started (Unix)' guide I get: $ arm-none-linux-gnueabi-g++ test-regex.cpp -I. stage/lib/libboost_regex-gcc42-mt-1_35.so /tmp/ccVow1Eq.o: In function `boost::detail::atomic_decrement(int*)': test-regex.cpp:(.text._ZN5boost6detail16atomic_decrementEPi[boost::detail::atomic_decrement(int*)]+0x18): undefined reference to `__sync_fetch_and_add_4' collect2: ld returned 1 exit status With assistance on the boost-build list I've ascertained that the problem is that GCC doesn't support __sync_fetch_and_add and the other atomic built-ins on ARM. An additional case for this may need to be added to boost/detail/sp_counted_base.hpp I don't know enough to patch boost for this, short-term or otherwise; can anyone offer any advice? TIA, --rob

Is the review schedule correct on the new website?
by dan marsden 04 Apr '08

04 Apr '08

Hi I'm the review manager for the Egg library that starts on 31 March. I used to see Egg in the review schedule, but I checked today and we'd disappeared. I've assumed that is some versioning issue with the website, and kicked off the review anyway, I hope thats ok with the review wizard(s). The online schedule doesn't contain any reviews scheduled after Feb of this year, so it just looks like an out of date copy to me. Cheers Dan ___________________________________________________________ Yahoo! For Good helps you make a difference http://uk.promotions.yahoo.com/forgood/

[statechart] Mangled TOC?
by John Maddock 04 Apr '08

04 Apr '08

I'm not sure if this is a bug in the quickbook docs or deliberate, but the Table of contents here: http://www.boost.org/doc/libs/1_35_0/libs/statechart/doc/index.html looks kind of mangled around the PDF links. Was this intended to look this way, or just a slip? Cheers, John.

[Logging] Defining a to_string destination
by Manuel Jung 04 Apr '08

04 Apr '08

Hi, I would like to log to a standard container like std::list<std::string> or something similar, so i can send my logs to another program over network. But i have problems defining my own destination. For now it would be ok, to log just to a string. But i don't understand how to define my own destination in the right way. I looked at http://torjo.com/log2/doc/html/namespaceboost_1_1logging_1_1manipulator.htm… but i don't understand the "sharing data" part well. Maybe someone can help me out here? I have so far: struct to_string : boost::logging::destination::class_<to_string, boost::logging::destination::implement_op_equal::has_context> { std::string s; to_string(std::string s) : s(s) {} bool operator==(const to_string& other) { return s == other.s; } // param = const std::string& // (in other words, it's the arg_type from your destination base class) void operator()(param msg) const { // s.append(msg); } But even that is not compiling. Any help would be appreciated! :-) Greetings Manuel Jung
