Any interest in type_traits workaround macros for ill conforming compilers?
by Ray Hilton 22 Dec '04

22 Dec '04

Something along theese lines #include <boost\type_traits.hpp> #define BOOST_REMOVE_POINTER(arg) \ namespace boost \ { \ template <> \ struct remove_pointer<arg*> \ { \ typedef arg type; \ }; \ } // end namespace boost user file struct abc { object x; object b; }; BOOST_REMOVE_POINTER(abc) boosts remove_pointer<T> will now work as expected for abc types Do such macros already exist in boost? Such macros can also be used on good compilers* to describe traits that it can't figure out, such as has_nothrow_assign<T> * compilers supporting partial template specialization

operators.hpp question.
by Fracassi＠t-online.de 22 Dec '04

22 Dec '04

Hello, I am trying to use the operators.hpp templates to create the following behaviour. I have a templated class like this. template <class T> class example {} now I want to do something like this: example<SomeType> r; example<SomeType> a; example<AnotherType> b; r = a * b To write the multiplication manually I would have to write a function template template <class T, class OtherT> example<T> operator*(const example<T>& op1, const example<OtherT>& op2); So, now my question is: How can this be done with operators.hpp? Obviously ... template <class T> class example : boost::multiplicative2<example<T>, example<OtherT> > { template <OtherT> example<T>& operator*=(const example<OtherT>& op); template <OtherT> example<T>& operator/=(const example<OtherT>& op); } ... won't work, since "OtherT" isn't defined at its first occurrence. Is there a way to do what I intended, or do I have to write these operators manually? Thanks, Fabio Fracassi

[iterator] iterator_facade operator-> pointee always const
by Tobias Schwinger 22 Dec '04

22 Dec '04

Hi, While using boost::iterator_facade wirh a class type as argument for both the 'Reference' and the 'Value' template type parameter I noticed that I can't access non-const members via operator->. *i is not const and neither 'Value' nor 'Reference' are. A naiv look at the source shows me that operator_arrow_proxy::operator->() always returns 'T const *'. Is this a bug or an intentional restriction ? I'm using the current CVS version (just updated, head revision) and tried to compile with GCC and MSVC. Thanks for any help in advance, Tobias

hello , Robert Ramey In the last lettler , I forgot to tell you the error info of compiler. The msvc71 said that "wchar_t const * " can't be converted to type "std::wstring::const_iterator" , at the file "xml_escape.hpp" line 47. in stlport 4.6.2 , "std::wstring::const_iterator" is "const wchar_t * "(so I was mazed by the error info! ),but in ms-stl(vc71) , "std::wstring::const_iterator" is a nested class in basic_string<>.I don't konw what does stl_port4.53 implemented wstring. Another thing is : when i copy the file "xml_woarchive.cpp" to a simple msvc porject and compile it alone , there is no any error occured , regardless whether stlport is used. I think this is because some macro are difference between jam and ide enviroment , but I'm not sure. Robert Ramey wrote: > >> Do you think the modified code is right ? > >basically yes, it also eliminates a wcslen which is a good thing. I don't unstandard this word. do you talk about Run-Time Library function wcslen() ? in my opinion , with stl string , this function has no use . goodmen(a)x263.net 2004-12-23

Dear Robert Ramey, I'm SO sorry to bother you again! When I compile Boost::Serialization(version 1.32.0) using msvc71+stlport4.6.2, I fond compile error in the file "xml_escape.hpp" line 47. I followed the way compile shown , and find the cause is in file "xml_woarchive_impl.ipp" line 108 . I think it is more reasonable to alter the function like this : /////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////// #ifndef BOOST_NO_STD_WSTRING template<class Archive> void xml_woarchive_impl<Archive>::save(const std::wstring & ws){ typedef iterators::xml_escape<std::wstring::const_iterator> xmbtows; // This is changed by zhengyi !! otherwise ,using stlport can not // compile successfully std::copy( xmbtows(BOOST_MAKE_PFTO_WRAPPER(ws.begin()/*ws.data()*/)), xmbtows(BOOST_MAKE_PFTO_WRAPPER(ws.end()/*ws.data() + ws.size()*/)), boost::archive::iterators::ostream_iterator<wchar_t>(os) ); } #endif //BOOST_NO_STD_WSTRING /////////////////////////////////////////////////////////////////////////////// /////////////////////////////////////////////////////////////////////////////// When I using above code instead yours, the compiler seems happy. and when i switch to ms stl ,that's ok. The original code of yours can pass when using ms-stl , but will fail with stlport. Can you explain that ? Do you think the modified code is right ? How Can I build successfully without alter your code(I like stlport and do not want to define macro BOOST_NO_STD_WSTRING to avoid compile error ) ? Thanks for your patience to read this letter! Merry Christmas!! (two days early ^_^) goodmen(a)x263.net 2004-12-22

Still having trouble with Mingw and install.

I just did bjam -sTOOLS=MINGW --install >From what I read that is supposed to put the libraries in c:\boost\lib and include in c:\boost\include.. It didn't. Now I think I did that the way the last reply said to so it should ahve worked any ideas? Kenx

Q: boost::format : can formatting variable arguments lists be done ?
by Dan Dimerman 22 Dec '04

Hello, Currently I have a piece of code that logs messages much in the same way as printf() : void MyLogger::dump( const std::string& format, va_list& list ) { const unsigned short buf_size = 1024; char buffer[ buf_size ]; ::memset( buffer, 0, buf_size ); ::_vsnprintf( buffer, buf_size - 1, format.c_str(), list); /.../ } After many headaches (and crashes) due to mistaken format specification fields, I thought to upgrade my class's API to use boost::format, but alas, I couldn't find the way to feed the format object from a va_list. Is there a way? thanks in advance... Dan.

[newbie] building serialization library

hi, Is it possible to build the boost serialization library using VC6 compiler. --annamalai -----Original Message----- From: boost-users-bounces(a)lists.boost.org [mailto:boost-users-bounces@lists.boost.org]On Behalf Of Frank Brown Sent: Thursday, December 16, 2004 6:37 AM To: boost-users(a)lists.boost.org Subject: [Boost-users] newbie build question sorry if this has been asked before, it's very elementary but i can't find references in the archives or faq so here goes: i just installed boost libraries and built them via bjam. they seemed to build successfully. i'm using the vc7.1 compiler. when i try to compile (cl) a .cpp file containing the following include #include <boost/regex.hpp> i get the following: testBoost.cpp(8) : fatal error C1083: Cannot open include file: 'boost/regex.hpp': No such file or directory if i replace the include with the actual file spec like this: #include "C:\Boost\include\boost-1_32\boost\regex.hpp" i get the following compiler error: testboost.cpp C:\Boost\include\boost-1_32\boost\regex.hpp(28) : fatal error C1083: Cannot open include file: 'boost/regex/config.hpp': No such file or directory apparently the compiler (cl) isn't translating <boost>. since one boost header refers to others i need to fix this basic problem. i tried substituting the bjam.exe in place of cl to compile, then i get a different error: Unable to load Boost.Build: could not find "boost-build.jam" --------------------------------------------------------------- Attempted search from D:\c\whereis up to the root so i'm sorry to bother y'all with such a simple problem, all i need to know is how to compile (the 'hello world' scenario). thanks for your attention. -frank brown (stupid jerk) http://www.inwa.net/~frog _______________________________________________ Boost-users mailing list Boost-users(a)lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
