Pb with threads on Mac OS X Carbon.
by degaine1966 03 Sep '03

03 Sep '03

Hi, I'd like to use shared pointers with CodeWarrior 8.3 in a Carbon application. I have some preprocessing errors, the first one being relative to a thread Macro being undefined: lightweight_mutex.hpp line 86 # error Unrecognized threading platform I read in boot/config/plateform/macos.hpp that Boost was thread safe under Carbon but apparently there is no macro to define the usable type of thread... Any help appreciated, Bruno

Filesystem Lib Feature Request
by Robert W. Johnstone 03 Sep '03

03 Sep '03

Hello, Has any thought been given to member functions for the path class for handling filename extensions? It should be easy to add code for most systems to extract or change the extension. Thanks, ------------------------------------------ Robert Johnstone Simon Fraser University http://www.sfu.ca/~rjohnsto/

ostream_iterator and std::copy - better solutions?
by Jeff Flinn 03 Sep '03

03 Sep '03

Before rolling my own, does boost have a facility to stream out an iterator range without the dangling delimiter at the end? For example std::ostream& operator<<( std::ostream& s, const MyClass& aC ) { const std::string lDelim( "," ); std::vector<int> lInts; lInts.push_back(1); lInts.push_back(2); lInts.push_back(3); std::ostream_iterator<int> lItr( s, lDelim.c_str() ); std::copy( lInts.begin(), lInts.end(), lItr ); } yields: 1,2,3, I'm thinking something like the following usage would be nice: s << range_streamer( lInts.begin(), lInts.end(), "{", "," "}" ); yielding: {1,2,3} Any thoughts? -- Jeff Flinn Applied Dynamics, International

So what I actually wanted was: for_each( v.begin(), v.end(), cout << _1 << '\n' ); That'll teach me copy code from two different examples without applying my brain to it. Thanks, Matt!

boost lambda examples
by paulgrenyer 03 Sep '03

03 Sep '03

Hi MSVC 7.1, Windows 2000 I'm trying to get to grips with the boost lambda library. I've managed to get the first example to work: #include <boost/lambda/lambda.hpp> #include <iostream> #include <cstdlib> #include <list> #include <algorithm> int main() { using namespace std; using namespace boost::lambda; list<int> v(10); for_each(v.begin(), v.end(), _1 = 12 ); return EXIT_SUCCESS; } but when I add the following line (also from the docs): for_each( v.begin(), v.end(), cout << *_1 << '\n' ); I get the following errors: error C2039: 'reference' : is not a member of 'std::iterator_traits<int>' error C2146: syntax error : missing ';' before identifier 'type' error C2501: 'boost::lambda::detail::contentsof_type<A>::type' : missing storage-class or type specifiers error C2039: 'type' : is not a member of 'boost::lambda::detail::contentsof_type<A>' error C2146: syntax error : missing ';' before identifier 'type' I've tried including some the other Lambda headers but this didn't improve the situation. Regards Paul

"invalid token pasting" macro bug
by James W. Walker 03 Sep '03

03 Sep '03

When I use Spirit with CodeWarrior 9 (just released), I get a bunch of warnings as shown below. The CodeWarrior release notes explain that "According to the language standard, the '##' token pasting operator can only generate other tokens. This warning indicates when a paste was found that did not result in a token. The code will still compile as it did previously, but it may be a useful hint if the compiler emits an error later on." Warning : invalid token pasting of 'BOOST_PP_LIST_FIRST_I' and '(' (included from: expanding macro 'BOOST_PP_LIST_FIRST' expanding macro 'BOOST_PP_LIST_FOR_EACH_I_M_D' expanding macro 'BOOST_PP_LIST_FOR_EACH_I_M' expanding macro 'BOOST_PP_FOR_1_C' expanding macro 'BOOST_PP_FOR_1' expanding macro 'BOOST_PP_LIST_FOR_EACH_I' type_traits.hpp:58 composite.ipp:16 composite.hpp:15 directives.hpp:27 numerics.hpp:19 core.hpp:34 spirit.hpp:30 ParseCalcLine.cp:5) type_with_alignment.hpp line 55 on_ptr, BOOST_PP_NIL)))))))))))) -- <http://www.jwwalker.com/>

how to create fixtures in unit test framework
by Anders Moe 03 Sep '03

03 Sep '03

Hi all. The boost unit test framework seems to lack the xUnit buildUp/tearDown (whatever) methods meant to faciliate the creation of fixtures. Does that mean there is an alternative idiom to achieve the same effect ? Constructing new class-test-cases for each test seems a bit overkill. Regards, Anders.

Lambda operator= question
by Rodolfo Lima 02 Sep '03

02 Sep '03

Hi people, That's the first time I'm using lambda and I'm stuck with something that can be resumed to: struct A { int Test() { return 0; } }; int x; A a; (var(x)=bind(&A::Test,_1))(a); In other words, I want to make a functor that calls a member function and stores its return value in some variable. I'm compiling with VC7.1 and it returns error C2440: '=' : cannot convert from 'const boost::tuples::cons<HT,TT>::stored_head_type' to 'int' Is there something I can do to get rid of this error and compile successfully? I'm appending the whole compiler output in the end of the post.

CodeWarrior PS2, Boost, & STL
by Yohann DOS SANTOS 02 Sep '03

02 Sep '03

Hello Boost Users, When i try to compile a class that use a vector with CodeWarrior for PS2 R3.03, i have this error message : Error : illegal use of incomplete struc/union/class 'Metrowerks::compile_assert<0>' (instantiating: 'std::vector<int, std::allocator<int>>') (instantiating: 'std::__vector_imp<int, std::allocator<int>, l>') vector line 729 ompile assert<bool(sizeof(T) == sizeof(typename Metrowerks::strore_as<T>;;type))> And just above the error line, in the vector file : // Error : illegal use of incomplete struct/union/class 'Metrowerks::compile_assert<0>' // This means that the store_as table in <msl_utility> is not set correctly. // sizeof(T) == sizeof(typename Metrowerks::store_as<T>::type must be true. The code compiles and works perfectly with VC6 sp5 on PC and XBOX. Thanks for any help.
