Problems when compiling with Xcode
by Jaime Rios 13 Sep '06

13 Sep '06

Hi folks, I didn't see my post appear on the list, so I will post it again... This might be a silly question, or one that has already been addressed in the past, but here goes anyway. I have Xcode 2.4 and recently, I had to compile a static library for Universal code. I had to install the 10.2.8 Mac OS X sdk and when I went to compile my library, I got 66 errors :( Here is the first error I saw: from /Users/me/Documents/development/CPP/FMPlugIns/ FM85/FMPlugInSDK/plugin_u/Source/FMPlugInExample.cpp:41: from ../Libraries/FMWrapper.framework/Headers/ FMXTypes.h:15, from ../Libraries/FMWrapper.framework/Headers/ FMXClient.h:15, from /Developer/SDKs/MacOSX10.2.8.sdk/usr/include/ gcc/darwin/3.3/c++/stdexcept:45, from /Developer/SDKs/MacOSX10.2.8.sdk/usr/ include/gcc/darwin/3.3/c++/string:47, from /Developer/SDKs/MacOSX10.2.8.sdk/usr/ include/gcc/darwin/3.3/c++/bits/char_traits.h:46, from /Developer/SDKs/MacOSX10.2.8.sdk/usr/ include/gcc/darwin/3.3/c++/bits/fpos.h:45, from /Users/jaimerios/Documents/development/ cpp/Tools/boost_1_33_1/boost/compatibility/cpp_c_headers/cwchar:8, from /usr/include/wchar.h:71, from /usr/include/_types.h:27, from /usr/include/sys/_types.h:27, In file included from /usr/include/machine/_types.h:26, /usr/include/ppc/_types.h:73: error: conflicting types for `typedef union __mbstate_t __mbstate_t' The last error is the interesting one. I am assuming that the Boost sdk is forcing my compiler to look in the /usr/include path for the string header file instead of the Mac OS X 10.2.8 sdk path. Is this assumption correct? If so, how do I correct this problem? -Jaime

[fusion] transform a vector of values to refs
by Andy Little 13 Sep '06

13 Sep '06

Hi, I am trying to transform from a fusion vector of values to a fusion vector of non-const references to those values, the ultimate aim being to assign the original sequence from another sequence. The code below works ok with make_vector, but I want to be able to automate it for any fusion sequence. How can I do that? Current efforts follows: regards Andy Little #include <quan/out/current.hpp> #include <quan/matrix/out/matrix.hpp> #include <quan/operators/binary_operator_functors.hpp> #include <boost/fusion/sequence/io.hpp> #include <boost/fusion/sequence.hpp> #include <boost/ref.hpp> // try to make a function object to wrap references // in fusion style, with boost::ref struct add_reference_wrapper{ template <typename T> struct result{ typedef boost::reference_wrapper<T> type; }; template <typename T> typename result<T>::type operator()(T & t)const { return boost::ref(t); } }; int main() { using boost::fusion::at_c; typedef boost::fusion::vector4< quan::current::A, quan::current::mA, double,double > fusion_sequence_type; fusion_sequence_type sequence( quan::current::A(3), quan::current::mA(2), 1,1 ); std::cout << "before : " << sequence <<'\n'; // This works OK, and and assign the sequence to itself; std::cout << "after : " << boost::fusion::as_vector( boost::fusion::transform( boost::fusion::make_vector( boost::ref(at_c<0>(sequence)), boost::ref(at_c<1>(sequence)), boost::ref(at_c<2>(sequence)), boost::ref(at_c<3>(sequence)) ),sequence, quan::operator_plus_equals() ) ) <<'\n'; //############################################# // But cant make a vector of non const references boost::fusion::as_vector( boost::fusion::transform( sequence,add_reference_wrapper() ) ); //############################################# }

Actually, even in strict C, good programmers tend to do something like: T * make_T(T1 p1, T2 p2); T1 do_op1(T*this__,...) And make T opaque, i.e. C++ in C. Sohail

Iterating over MPL container
by Johan Torp 13 Sep '06

13 Sep '06

Given an MPL container: struct A{}; struct B{}; typedef boost::mpl::vector<A,B> AB and a templated function, specialized for all members of the MPL container: template<class T> void foo(); template<A> void foo(); template<B> void foo(); I would like to be able to generate the code: foo<A>(); foo<B>(); automatically using AB somehow. That is, I would like to iterate through the MPL container and generate a call to void Foo<T>(); for each member T in the container. How do I achieve this?

The aCC deployed on PA-RISC is a verry old (version 3.x) and is not conform to the current c++-standard (aCC-3.x has problems with templates). I got boost never compiled on this platform with aCC-3.x. I use gcc (depot from HP-website) and it works very well. If you can switch to Itanium-HP/UX you can use aCC-6.x which should work with boost. regards, Oliver

[date_time] Compilation error with MSVC8
by Eoin 13 Sep '06

13 Sep '06

Hello, before I explain my problem I'd like to apologize in advance if the error is on my part. Also this might have double posted because I believe I made an error initially, sorry if that's the case. I have a program using the date_time library. It compiles with msvc7.1 and MinGW but not under msvc8. Very simple usage is enough to recreate the error: #include <boost/date_time/posix_time/posix_time.hpp> ... boost::posix_time::ptime tim = boost::posix_time::second_clock::local_time(); std::cout << tim; I've attached the error output to this mail, I realize it is long but I wasn't sure if any bits could be safely left out. Any help that can be offered on this issue would be very much appreciated. Kind regards, Eoin C:\Develop\Libraries\Boost\boost\boost/range/const_iterator.hpp(37) : error C2825: 'C': must be a class or namespace when followed by '::' C:\Develop\Libraries\Boost\boost\boost/algorithm/string/replace.hpp(656) : see reference to class template instantiation 'boost::range_const_iterator<C>' being compiled with [ C=const char * ] C:\Develop\Libraries\Boost\boost\boost/date_time/time_facet.hpp(257) : see reference to function template instantiation 'void boost::algorithm::replace_all<std::basic_string<_Elem,_Traits,_Ax>,const char*,std::basic_string<_Elem,_Traits,_Ax>>(SequenceT &,const Range1T &,const Range2T &)' being compiled with [ _Elem=char, _Traits=std::char_traits<char>, _Ax=std::allocator<char>, SequenceT=std::basic_string<char,std::char_traits<char>,std::allocator<char>>, Range1T=const char *, Range2T=std::basic_string<char,std::char_traits<char>,std::allocator<char>> ] C:\Develop\Libraries\Boost\boost\boost/date_time/time_facet.hpp(239) : while compiling class template member function 'std::ostreambuf_iterator<_Elem,_Traits> boost::date_time::time_facet<time_type,CharT>::put(OutItrT,std::ios_base &,char,const time_type &) const' with [ _Elem=char, _Traits=std::char_traits<char>, time_type=boost::posix_time::ptime, CharT=char, OutItrT=std::ostreambuf_iterator<char,std::char_traits<char>> ] C:\Develop\Libraries\Boost\boost\boost/date_time/posix_time/posix_time_io.hpp(51) : see reference to class template instantiation 'boost::date_time::time_facet<time_type,CharT>' being compiled with [ time_type=boost::posix_time::ptime, CharT=char ] Hello_Con\src\ConsoleTimeClient.cpp(41) : see reference to function template instantiation 'std::basic_ostream<_Elem,_Traits> &boost::posix_time::operator <<<char,std::char_traits<char>>(std::basic_ostream<_Elem,_Traits> &,const boost::posix_time::ptime &)' being compiled with [ _Elem=char, _Traits=std::char_traits<char> ] C:\Develop\Libraries\Boost\boost\boost/range/const_iterator.hpp(37) : error C2039: 'const_iterator' : is not a member of '`global namespace'' C:\Develop\Libraries\Boost\boost\boost/range/const_iterator.hpp(37) : error C2146: syntax error : missing ';' before identifier 'type' C:\Develop\Libraries\Boost\boost\boost/range/const_iterator.hpp(37) : error C2208: 'boost::type' : no members defined using this type C:\Develop\Libraries\Boost\boost\boost/range/const_iterator.hpp(37) : fatal error C1903: unable to recover from previous error(s); stopping compilation

Hello all, I'm attempting to build Boost filesystem as a shared library on HP using aCC(I have no choice, I have to use this compiler). Here is machine and compiler info: HP-UX B.11.11 U 9000/800 (tb) aCC: HP ANSI C++ B3910B A.03.63 I have done a libs/config/configure and generated a user.hpp file for this compiler, but using the config doesn't help any.
