I tried to build boost 1.32.0 with jam optioned as "- snative-wchar_t=on". But cl option didn't include a '/Zc:wchar_t'. :( Therefore, i modified "tools/build/v1/vc-7_1- stlport.tools.jam" as following (not correct fix, just for workaround) #feature native-wchar_t : off on ; feature native-wchar_t : on off ; Finally it worked! - veblush ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1070327&group_… ------------------------------------------------------- This SF.Net email is sponsored by: InterSystems CACHE FREE OODBMS DOWNLOAD - A multidimensional database that combines robust object and relational technologies, making it a perfect match for Java, C++,COM, XML, ODBC and JDBC. www.intersystems.com/match8 _______________________________________________ Boost-bugs mailing list Boost-bugs(a)lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/boost-bugs

boost 1.32 acknowledgements
by Bronek Kozicki 21 Nov '04

21 Nov '04

In the acknowledgements section I see my name twice, while I do not see Aleksey Gurtovoy . I understand that our release manager is very modest person, but listing my name (person who did very little for Boost, if anything) and forgetting name of release manager seems wrong. B.

Build of boost_1_32_0 hangs on MacOS X build
by Steve Hartwell 21 Nov '04

21 Nov '04

Could other MacOS X developers confirm that the boost build 1.32 candidate fails to build on MacOS 10.3.6 with gcc 3.3? The problem I'm seeing is that while compiling "xml_grammar.cpp", cc1plus slows to a crawl while its virtual memory allocation rises to 1.8GB until my system becomes so unresponsive I have to kill it. Jam then proceeds until the release build of "xml_grammar.cpp", with the same results (cc1plus hanging). Killing that process leads to the same problems in the debug compile of "xml_wgrammar.cpp", as well as the release compile of "xml_wgrammar.cpp". I have observed this problem both with a dual-processor G5 and a single-processor G4. Everything else in the build seems to be proceed OK after I kill the cc1plus processes that hang on "xml_grammar.cpp". The command line I'm using to build is: bjam -sTOOLS=darwin -sBUILD="debug release <runtime-link>static/dynamic" Please let me know if anyone is having better luck with this. Best regards, Steve Hartwell p.s. There is an additional difficulty with the build of boost 'serialization' where some directory names end with ".a" and ".dylib". Although these are legal directory names, this confuses the heck out of the Xcode IDE, and makes it impossible to include the contents of these named directories into an Xcode project. It would be nice if the names of these directories could be changed to end with "_a" and "_dylib" instead, or something similar. p.p.s. boring (but precise) stuff about the cc1plus hang follows: When cc1plus hangs, ps shows the following arguments: /usr/libexec/gcc/darwin/ppc/3.3/cc1plus -quiet -Ibin/boost/libs/serialization/build -I/usr/include -I/Volumes/Nod/Users/hartwell/Documents/Development/Building Blocks/C-C++/BOOST/boost_1_32_0 -D__GNUC__=3 -D__GNUC_MINOR__=3 -D__GNUC_PATCHLEVEL__=0 -D__APPLE_CC__=1666 -D__DYNAMIC__ -DNDEBUG -DNDEBUG -DBOOST_TEST_NO_AUTO_LINK=1 /Volumes/Nod/Users/hartwell/Documents/Development/Building Blocks/C-C++/BOOST/boost_1_32_0/libs/serialization/build/../src/ xml_wgrammar.cpp -D__GNUG__=3 -fPIC -quiet -dumpbase xml_wgrammar.cpp -auxbase-strip bin/boost/libs/serialization/build/libboost_wserialization.a/darwin/ release/runtime-link-static/xml_wgrammar o -O3 -Wno-long-double -Wno-inline -Wall -ftemplate-depth-256 -finline-functions -fcoalesce-templates -D__private_extern__=extern -o Since this is all 'ps' is willing to output for this process, here is the parent process, whose arg list seems more complete: c++ -c -ftemplate-depth-256 -DNDEBUG -DNDEBUG -DBOOST_TEST_NO_AUTO_LINK=1 -Wno-long-double -no-cpp-precomp -O3 -finline-functions -Wno-inline -Wall -fcoalesce-templates -Ibin/boost/libs/serialization/build -I/usr/include -I/Volumes/Nod/Users/hartwell/Documents/Development/Building Blocks/C-C++/BOOST/boost_1_32_0 -o bin/boost/libs/serialization/build/libboost_wserialization.a/darwin/ release/runtime-link-static/xml_wgrammar.o /Volumes/Nod/Users/hartwell/Documents/Development/Building Blocks/C-C++/BOOST/boost_1_32_0/libs/serialization/build/../src/ xml_wgrammar.cpp

Library TR draft available
by Beman Dawes 20 Nov '04

20 Nov '04

The latest draft of the C++ Standard Library Technical Report is now available at http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2004/n1711.pdf There may be editorial (non-substantiative) changes to the final version of the TR document, but this latest draft is believed to be final in terms of technical content. Thus it should be safe for implementors or users to write code based on this latest draft. It will be several years before most compilers come with a full implementation of the TR. But some vendors (Metrowerks, for example) are already shipping a few TR components. That brings up the question of what Boost code does during the transition. To insure Boost code works with various TR implementations, some Boost code will want to use the compiler vendor's version of the TR if the TR component required is available, but otherwise will want to use Boost equivalent code. How do we handle that? The TR doesn't provide in configuration macros, so I guess we will have to roll our own. --Beman

RE: [boost] GUI validation [was: GUI Library Proposal for a Proposal]
by Arias Brent-P96059 20 Nov '04

20 Nov '04

I have not been paying attention to any of the GUI posts - until now. So I havn't the slightest idea if my comment is relevant. Here it goes: >** events, propagation and handling mechanisms, (event_target, listener, >subscribers...) I've never seen an "events, propagation, handling" mechanism as elegant as Miro Samek's Quantum Framework / Quantum Hierarchical State Machine. If there are any reading this who have not heard of it - you'd do well to buy his book and "settle in". At work we're using it for an embedded software defined radio, and at home I intend on using it for GUI/DirectX development. -Brent

The documentation for bjam setup in more/getting_started.html says to "chdir boost-1.31.0" as a possible place to you may have installed boost. Should this be made 1.32.0? Jared McIntyre

Macro for using overloaded functions with templated code.
by Daniel James 19 Nov '04

19 Nov '04

I've written a macro (the implementation is attached) for generating a function object for using overloaded functions with generic code such as the STL algorithms and boost::bind. A simple example of it's use: void foo(int); void foo(char*); GENERATE_OVERLOADED(void, foo); int main() { int values[] = { 1, 2, 3, 4 }; std::for_each(values, values+4, foo_overloaded); } GENERATE_OVERLOADED (yes, the naming is pretty bad) creates an object called which contains overloaded calls to operator() which forward to the named functions. Something like: struct foo_overloaded_type { void operator() const { return foo(); } template <class T1> void operator(T1 const& p1) const { return foo(p1); } template <class T1, class T2> void operator(T1 const& p1, T2 const& p2) const { return foo(p1, p2); } // etc. } foo_overloaded; The main advantage is that you don't have to select the desired overload. It can also be useful when different calls will have different argument types such as iterating over a tuple in fusion (I guess you could call it a visitor). Any comments on this? Would anyone else find this useful? Also, has anyone done something similar? I'd be surprised if no one has, I always feel like I'm missing something when I'm doing this kind of thing. The implementation is lacking in several ways - it doesn't work for non-const references, the return type is fixed, needs to deal with member functions, namespace issues and so on. I suppose, it could also be better integrated with bind, lambda or pheonix. Daniel

configure script not executable
by Jonathan Wakely 19 Nov '04

19 Nov '04

The libs/config/config.htm page says you should run /libs/config/configure as "./configure" but the file isn't executable in either CVS or the 1.32.0 release candidate. The docs should be changed as per the attached patch, although it might be too late for 1.32 jon -- "Self-respect: the secure feeling that no one, as yet, is suspicious." - H.L. Mencken

preprocessor fix
by Arias Brent-P96059 19 Nov '04

19 Nov '04

I've invented a printable enum, based on the Boost preprocessor programming lib. But although the printable enum works, I think my efforts revealed a bug in Boost. The BOOST_PP_SEQ_ENUM preprocessor macro doesn't work with the empty "false" result of BOOST_PP_EXPR_IIF. This has forced me to do hacks like this: #define ENUM(name, start, entries)\ BOOST_PP_SEQ_ENUM( \ BOOST_PP_IIF(ENUMS, \ (typedef enum{ BOOST_PP_SEQ_HEAD(entries) = start) \ BOOST_PP_SEQ_TAIL(entries) \ (LAST_##name } name;) \ , \ (static void PP_NILFUNC();) \ ) \ ) As you can see in the above definition, I've included an explicit "false" clause for BOOST_PP_IIF() that expands into the harmless (and utterly superfluous) expression "static void PP_NILFUNC();". I would instead have preferred to use BOOST_PP_EXPR_IIF and thus avoid the eye-sore. But the hack was necessary, as I said before, because BOOST_PP_SEQ_ENUM does not elogantly handle the empty "false" result of BOOST_PP_EXPR_IIF. Can this be fixed? -Brent
