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

Hi all, I was using a a boost library boost_1_30_0. now i tried to use new boost realease boost-1.30.2. But compiling the same application with new boost library results in error Thread support is unavailable! as BOOST_HAS_THREADS Macro is not defined. This is wht i have doen to install boost under RedHat8.0 Linux ./configure bjam How can i rectify it? Rgds Lalit _________________________________________________________________ Pinjar is a classic!

MultiArray - issue with views and striding

Hi, It appears you have correctly diagnosed a bug in the code for views. Thank you. I will check a fix into the Boost CVS. Cheers, ron

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; ... }
