Compiler command line options...
by Soumitra Chatterjee 10 Nov '03

10 Nov '03

Hi, I am a newbie, and I have a very basic question regarding compilation of boost libraries. Setup: I am using the bjam setup to build and test the boost library. I use something like $ cd <boost-root> $ bjam -a "-sTOOLS=acc" to try and build the library. Problem: I would like to add some compiler options (eg -myopt) during the build. How and where do I add them? Thanks in advance. -- Soumitra

2 bind questions
by Angus Leeming 07 Nov '03

07 Nov '03

I'm having some problems with bind and wonder if someone might help. The attached file compiles and runs fine when compiled with boost-1.30.2 (g++ 3.2 on a PC and g++ 3.3 on a Dec Alpha, both running linux). However, compilation fails if I uncomment the overloaded 'node' member function below. struct FEM { typedef std::vector<Node>::size_type size_type; FEM(std::vector<Node> const & nodes) : nodes_(nodes) {} size_type nnodes() const { return nodes_.size(); } Node & node(size_type i) { return nodes_[i]; } // Node const & node(size_type i) const { return nodes_[i]; } private: std::vector<Node> nodes_; }; boost/boost-1.30.2/boost/function/function_template.hpp:117: could not convert `f->boost::_bi::bind_t<R, F, L>::operator()(A1&) [with A1 = size_t, R = const Node&, F = boost::_mfi::cmf1<const Node&, FEM, unsigned int>, L = boost::_bi::list2<boost::reference_wrapper<FEM>, boost::arg<1> >]((&a0))' to `Node&' Is there a fix for this or have I hit a brick wall? Second question. I'd like to combine these two boost::functions into a single boost::function2<void, size_t, double> all_in_one = ...; all_in_one(i, val); but I'm getting horribly lost trying to determine the '...'. Is it possible? Any clues? Kind regards, Angus ps. What is the prefered way of posting code? Inline or as an attachment? A std::vector<Node> nodes(10); FEM fem(nodes); size_t i = 5; double const val = 14; boost::function1<Node &, size_t> get_node = boost::bind(&FEM::node, boost::ref(fem), _1); boost::function1<void, double> set_value = boost::bind(&Node::set_conc, boost::ref(get_node(i)), _1); set_value(val);

There is a bug in 2.95.3 that causes it to fail rather than reporting this error in a helpful way: <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=3689>. If you remove the option '-fno-rtti' from the compiler command line it should work.

If you think your compiler is not smart enough to make a local copy of what x refers to when Type when that's likely to improve performance, you could use something like this: template<typename Type> void foo(const Type & arg_x) { typename boost::call_traits<Type>::param_type local_x = arg_x; ... }

Boost is unusual in that many of its libraries contain only inline and template functions that are compiled along with the client code. However, the date_time, filesystem, graph, python, regex, signals, test, and thread libraries have some code that must be separately compiled. See the file tools/build/index.html in the Boost distribution or on www.boost.org.

Boost isn't tested with anything older than version 2.95.3, and that only on Linux, with a 41% failure rate. (See <http://boost.sourceforge.net/regression-logs/> for the details.)

MultiArray - issue with views and striding.
by Nasatyr, Ben (London) 06 Nov '03

06 Nov '03

Can anyone help shed light on the following? Suppose I have a 1d-array of size 10 (index base is 0). If I create a view on [0,10), strided by 3, shouldn't the size of the result be 4, corresponding to indices 0, 3, 6 and 9? Instead I get 3. Please forgive me if I'm off the mark here, as I'm new to boost in general and MultiArray in particular. The relevant line (assuming len => size) in boost/multi_array/base.hpp seems to be index len = (finish - start) / index_factor; (boost::detail::multi_array::multi_array_impl_base<>::generate_array_view() line 427). I would have written index len = 1 + (finish - 1 - start) / index_factor; The following code sample should make all clear. Any clarification greatly appreciated. Cheers, Ben typedef boost::multi_array<double, 1> array_type; typedef array_type::index index; typedef array_type::index_range range; index i; int values = 0; // Setup our base array and data. // A is a 1-d array with size 10, indices 0,1,...,9 and values 0,1,...,9. array_type A(boost::extents[10]); for(i = 0; i != 10; ++i) A[i] = values++; for(i = 0; i != 10; ++i) assert(A[i]==i); assert(A.size()==10); // The following views of A should all be effectively the same, // corresponding to indices 0,3,6,9 of A, so having // size 4, indices 0,1,2,3 and values 0,3,6,9? array_type::array_view<1>::type view1 = A[boost::indices[range(0,12,3)] ]; array_type::array_view<1>::type view2 = A[boost::indices[range(0,11,3)] ]; array_type::array_view<1>::type view3 = A[boost::indices[range(0,10,3)] ]; for(i = 0; i != 4; ++i) { assert(A[i*3]==view1[i]); assert(A[i*3]==view2[i]); assert(A[i*3]==view3[i]); } assert(view1.size()==4); assert(view2.size()==4); // Assert fails!? assert(view3.size()==4); // Assert fails!?

Hi, It seems that you simply have not linked to the regex library. BTW, I believe the name is "regex" and that "Regex++" was the name before John Maddock ported his library to boost. Regex is one of boost library that does not consist only of headers. It needs an actual binary to link to. Which means you have to build it yourself. Have you gone through this stage ? If not I suggest you do not go through Bjam for this one and instead go to boost/libs/regex/build and run the VC7 make file there (vc7) inside the VC7 command console. If memory serves, it produces the complete set of static and dynamic libraries you need whereas Bjam does only part of it (or maybe I could not make it work properly). Then in your settings in the link tab put the path to the library you want to use (I believe a pragma lib takes care of choosing the one compatible with the version of the C library you compile with). Kind regards, Cyril Godart.

Is threads CodeWarrior project broken?
by Steve Folly 04 Nov '03

04 Nov '03

Hi, I'm trying to build the threads library on Codewarrior with the .mcp project supplied in libs/thread/build/ (using CW9, OS X 10.2.8), but Codewarrior says the file is not a project file. Is it broken? I could probably recreate it, but I'm not sure about about what source files to include for the Mac - there's all the extra stuff under src/mac/ and then what about the src/mac/msl_replacements/ stuff? Any help gratefully received. I'd like to do a multi-target project for Mac and Win32; tips for source files for Win32 would be helpful too. Thanks. Steve.

RE: [Boost-users] [BLL] How to search in a list for an object comparing a data member?

This is a documented limitation of the lambda library - there is no way to defer lookup of member names (overloading -> just changes the type and value of the pointer used) so member access can't be done on a placeholder. > I know I could use a functor object but this is just an example for a > more general need. Sorry, you'll have to define functors. These template functor classes might be useful: template<typename C, typename V, const V C::* P> struct lookup_member_const { const V & operator()(const C & c) const { return c.*P; } }; template<typename C, typename V, V C::* P> struct lookup_member { V & operator()(C & c) const { return c.*P; } }; Mind you, there might be similar things in Boost already.

Build+Install+/Zc:wchar_t in Visual studio builds
by John Maddock 01 Nov '03

01 Nov '03

Guys, Rene's new Install code is working very well for me now, but I have a question about how we're building with Visual Studio .NET. Currently the vc7 and vc7.1 toolsets turn on /Zc:wchar_t unconditionally when building, however this is not the default option in current versions of the IDE, and of course the two options produce binary-incompatible libraries (at least as far as regex is concerned). How should we handle this? At the very least I would like to see a bjam option to turn off /Zc:wchar_t, but how should we be building the libraries by default: turning native wchar_t support on is the standards conforming way, but not currently the default Visual Studio way, or the way many third party libraries (like ICU for example) are built. Does anyone know how this option interacts with MFC/ATL/VisualForms etc? We could of course create a new build variant to handle this, but with 8 regex lib/dll variants already I'm not keen to add another 8 (apart from anything else testing already takes too long). I'm cross posting this to the Boost.users group as well, since whatever resolution we take will affect them the most :-) Thanks, John.

[newbie] creating a (complex?) C++ wrapper around a C function call...
by Jason House 31 Oct '03

31 Oct '03

I want to create a wrapper function template <class foo> op_pk_fd_set_class(packet *packet, int index, foo &value, int simulated_bits); around the following function... (in OPNET) op_pk_fd_set( packet* pkptr, // same as in wrapper int index, // same as in wrapper int some_constant, //OPC_TYPE_STRUCT void* value, int simulated_bits, // same as in wrapper void* (*copy_proc)(void* obj_to_copy,int alloc_size), void (dealloc_proc*)(void *obj), int alloc_size); I believe dealloc_proc can just be a function pointer to the destructor. I could very well be mistaken, but I believe that a normal constructor takes only one parameter. I also think alloc_size should be sizeof(foo). I do not know how to obtain function pointers for constructor and deconstructor member functions. Any assistance I could get would be appreciated.
