[Proto] callable_context
by Hossein Haeri 04 Jan '11

04 Jan '11

Dear all, I am trying to use callable_contexts to evaluate expressions like: x >> f >> g >> h; where this would be equivalent to h(g(f(x))). I have derived my context from callable_context, and thought I have overloaded for relevant tags (terminal and shift_right). GCC 4.5.1 (MinGW32, WinXP, SP3) stops with an error message which is cryptic to my current level of knowledge about Proto. I guess that's because I haven't done the job correctely. For your reference, I have included a copy of my program as well as the error GCC gives me in the P.S. section of this posting. Any ideas please? TIA, --Hossein P.S. <code> #include <iostream> #include <boost/proto/proto.hpp> namespace mpl = boost::mpl; namespace proto = boost::proto; using proto::_; using namespace std; struct EWGrandDad { int evaluate() const; }; typedef proto::terminal<double (*) (double)> FunctionType; template<typename> struct EmtExpr; struct EmtGrammar: proto::or_ < proto::terminal<EWGrandDad>, proto::shift_right<EmtGrammar, FunctionType> > {}; struct EmtDomain: proto::domain<proto::generator<EmtExpr>, EmtGrammar> {}; template<typename Expr> struct EmtExpr : proto::extends<Expr, EmtExpr<Expr>, EmtDomain> { typedef proto::extends<Expr, EmtExpr<Expr>, EmtDomain> base_type; EmtExpr(const Expr& e = Expr()): base_type(e) {} }; struct EWBase : EmtExpr<typename proto::terminal<EWGrandDad>::type> { typedef typename proto::terminal<EWGrandDad>::type expr_type; EWBase(): EmtExpr<expr_type>(expr_type::make(EWGrandDad())) {} }; struct EW1: EWBase { EW1(int n1, int n2): n1_(n1), n2_(n2) {} int evaluate() const {return n1_ * n2_;} int n1_, n2_; }; double times2(double d) {return d * 2;} double minus1(double d) {return d - 1;} struct EmtContext: proto::callable_context<const EmtContext> { typedef double result_type; result_type operator() (proto::tag::terminal, const EWGrandDad& ew) const { return ew.evaluate(); } template<typename Expr> result_type operator() (proto::tag::shift_right, const Expr& e, FunctionType f) const { return f(proto::eval(e, *this)); } }; int main() { EmtContext emtCtx; cout << "result = " << emtCtx(EW1(4, 5) >> &times2 >> &minus1); return 0; } </code> <error message> main.cpp: In function 'int main()': main.cpp:82:63: error: no match for call to '(EmtContext) (const boost::lazy_enable_if_c<true, boost::proto::generatorns_::generator<EmtExpr>::result<EmtDomain(boost::proto::exprns_::expr<boost::proto::tag::shift_right, boost::proto::argsns_::list2<const EmtExpr<boost::proto::exprns_::expr<boost::proto::tag::shift_right, boost::proto::argsns_::list2<const EW1&, EmtExpr<boost::proto::exprns_::expr<boost::proto::tag::terminal, boost::proto::argsns_::term<double (* const&)(double)>, 0l> > >, 2l> >&, EmtExpr<boost::proto::exprns_::expr<boost::proto::tag::terminal, boost::proto::argsns_::term<double (* const&)(double)>, 0l> > >, 2l>)> >::type)' main.cpp:67:14: note: candidate is: EmtContext::result_type EmtContext::operator()(boost::proto::tag::terminal, const EWGrandDad&) const </error message>

Mingw64 Boost Threads Build
by Dustin T. Clifford 04 Jan '11

04 Jan '11

Good Afternoon, We have been using boost-threads for our native APIs and, thus far, Boost has been a godsend! We had a recent request to build a 64-bit version of this API. To accomplish this we have attempted to build using MinGW64. Unfortunately, I have had zero luck getting boost-threads to build. I can build the 32-bit address model without a problem but 64-bit continues to elude me. I first tried Boost 1.35.0 and have now moved on to 1.45.0. I believe that the environment is set up correctly (see below). This build is being performed on a Windows 7 64-bit using MinGW64 from Cygwin. export CC=x86_64-w64-mingw32-gcc.exe export CXX=x86_64-w64-mingw32-g++.exe export LD=x86_64-w64-mingw32-ld.exe I have, also, modified my PATH to use the appropriate 64-bit bintools and aliased gcc, g++ and ld to the 64-bit MinGW64 compilers and linkers. To build Boost I have used the following with no success. boostrap.sh address-model=64 -prefix=<install> --with-libraries=thread; bjam -a install; boostrap.sh -prefix=<install> --with-libraries=thread; bjam -a address-model=64 install; boostrap.sh -prefix=<install> --with-libraries=thread; bjam -a install; The last build attempt succeeds but appears to have built 32-bit binaries. The previous two fail in building boost-threads complaining that 'address-model-64' is not found for certain build artifacts. I have, also, tried the above with a prebuilt bjam with the same results. I have tried much more than what I have cited here (including MSVC builds) with no success (some built but resulted in 32-bit binaries). I have scoured Google and found many talking about this but most either had no resolution or contained instructions that conflicted or made no sense. Does anybody have any insight into how I can produce a 64-bit boost-threads archive? Any help would be greatly appreciated. Thanks in advance, Dustin P.S. If I have missed any information or you need more (build logs are too big to attach), please, let me know.

Improving extern template usage
by Jens Auer 04 Jan '11

04 Jan '11

Hi, I've been playing around with the extern template implementation of Visual C++ (2005 and 2010) to reduce our overly long build times. Microsoft's implementation does only omit implicit definitions for member functions not defined inline in the class body. This makes the feature rather useless to reduce build times, as most functions in the boost library (and Microsoft's STL) seem to be declared inline and get implicitly instantiated every time, thus forcing the linker to remove them which is quite costly. This behavior is also perfectly valid with the standard where an exception is made for member functions of template classes defined inline. Would it be reasonable to change the coding guidelines to only define trivial member functions in the class body and provide the definitions separatly after the class declaration? I think gcc does implicitly sinatntiate these member functions, but the MS compilers are widely used and a large number of users would benefit.

enable_if: fusion seq, vs2010 vs gcc
by Hicham Mouline 04 Jan '11

04 Jan '11

#include <iostream> #include <boost/utility/enable_if.hpp> #include <boost/fusion/include/is_sequence.hpp> struct S { double skid; }; template<typename Archive> void serialize(Archive& ar, S& sp, unsigned int) { std::cout<<"1st one"<<std::endl; } template <typename Archive, typename Seq> typename boost::enable_if_c<boost::fusion::traits::is_sequence<Seq>::value, void>::type serialize( Archive& ar, Seq& seq, unsigned int) { std::cout<<"2nd one"<<std::endl; } template void serialize<double>(double&, S&, unsigned int); int main() { S s; double d1=5.; serialize(d1, s, 5); return 0; } The above code compiles ok on gcc4.5.1 and prints 1st one. It crashes vs2008. vs2010 was fixed not to crash but fails to compile according to those who have vs2010. Is this correct code (I guess I mean standard conforming)? regards,

[units] subtract_typeof_helper<> help!
by Terry Golubiewski 04 Jan '11

04 Jan '11

I'm trying to use boost::geometry and boost::units together. For some reason boost::geometry doesn't represent the difference of two points as vectors. So, I'm making my own Vector class and defining Vector = Point - Point. The sample program below doesn't compile because I need to tell the units library about the special properties of point subtraction (I think). terry #include <boost/geometry/geometry.hpp> #include <boost/units/systems/si.hpp> #include <boost/units/quantity.hpp> #include <boost/units/io.hpp> #include <iostream> #include <iomanip> using namespace std; using namespace boost; using namespace boost::geometry; using namespace boost::units; typedef point<double, 3, cs::cartesian> Point; class Vector { Point _impl; friend Vector operator-(const Point& lhs, const Point& rhs); explicit Vector(Point p) : _impl(p) { } public: Vector() : _impl(0) { } Vector(double dx, double dy, double dz=0) : _impl(dx, dy, dz) { } friend ostream& operator<<(ostream& os, const Vector& v) { return os << dsv(v._impl); } }; // Vector inline Vector operator-(const Point& lhs, const Point& rhs) { Point tmp(lhs); subtract_point(tmp, rhs); return Vector(tmp); } inline ostream& operator<<(ostream& os, const Point& pt) { return os << dsv(pt); } int main() { Point p1(1, 2, 3); Point p2(4, 5, 6); typedef quantity<si::length, Point> Position; typedef quantity<si::length, Vector> Displacement; Position start( p1 * si::meters); Position finish(p2 * si::meters); Displacement disp(finish - start); cout << "disp=" << disp << endl; return EXIT_SUCCESS; } // main

[Proto] EvalStream Revisited -- Segmentation Fault
by Hossein Haeri 04 Jan '11

04 Jan '11

Dear all, A few weeks ago, I asked for help about an EDSL which can handle expressions like x >> f >> g >> h so that they're equivalent to h(g(f(x))) once evaluated. Eric kindly provided me with the solution in the P.S. I was just playing around with his code and thought about extending it with a simple case when f's and g's are actually functions, as opposed to function objects. So, I added the following two lines: int plus1(int i) {return i + 1;} const terminal<pointer_to_unary_function<int, int> >::type plus_one = {ptr_fun(&plus1)}; And, I get a segmentation fault (GCC 4.5.1, MinGW32, WinXP, SP3) when I run the following line: 1 >> plus_one >> plus_one Any ideas? TIA, --Hossein P.S. #include <boost/proto/proto.hpp> #include <iostream> namespace proto = boost::proto; using proto::_; struct add_one_ { typedef int result_type; int operator()(int i) const { return i + 1; } }; proto::terminal<add_one_>::type const add_one = {}; struct GetFun : proto::call<proto::_value(proto::_right)> {}; struct EvalStream : proto::or_< proto::when< proto::terminal<_> , proto::_value > , proto::when< proto::shift_right<EvalStream, proto::terminal<_> > , proto::lazy< GetFun(EvalStream(proto::_left)) > > > {}; int main() { // This prints "3" std::cout << EvalStream()( 1 >> add_one >> add_one ) << std::endl; }

[units] Automatic Physical Units in Mathematica and Boost.Units
by alfC 03 Jan '11

03 Jan '11

Since there are not many computer software that handles units seriously, except possibly for Boost.Units and Mathematica`Units in my opinion, I just wanted to point out to this post: Automatic Physical Units in Mathematica http://blog.wolfram.com/2010/12/09/automatic-physical-units-in-mathematica/ Interesting discussion in terms of features. One of the reasons I hated Mathematica units handling so far was due to the lack of a typing system which C++ and boost.Units have naturally, the other reason was that the physical quantites didn't seem to play well with other parts of the system. Now it seems that Mathematica Units is discovering "types". One of the features that it mentions is the ability to perform automatic conversions upon arithmetic operations of mixed units. In fact I was working in a way to perform automatic conversion in Boost.Units inside arithmetic formulas, since Mathematica has unbounded precision arithmetic by default the automatic conversions are not a real problem. An exact matching of this feature can not be achieved with a limited precision representation (like double). I'll take the opportunity ask two broad general questions: Does any body have experience with using boost.units quantity with a underlying type that are not double, e.g. multiple precision, or vector (geometric) objects? Does it work well? Are there future planned developments for Boost.Units, in terms of external features (e.g. automatic conversion, better interaction with boost.phoenix) or internal implementation? Thank you, Alfredo

mpi/serialization: string serialization and const char*
by Hicham Mouline 02 Jan '11

02 Jan '11

hello, Including I mpi::broadcast an object. Its serialization method is split into a save() and a load(). In the save(), I send: ar << "fixed_params"; where ar is a boost::mpi::packed_iarchive. At reception, the load() function : std::string paramstype; ar >> paramstype; if (paramstype=="fixed_params") /// this fails because the count of characters if 12 for 1 side and 13 for the other. The null character is there. Should this work? regards,

Dear all, Trying the Vector example at the Proto documentation: http://boost.org/doc/libs/1_45_0/doc/html/proto/users_guide.html#boost_prot… under Boost 1.42 and GCC 4.5.1 (MinGW32, WinXP, SP3), I get the error message in the PS.
