The same error can be produced with the following code (or anything like it). #include <vector> using namespace std; enum SomeEnum { vector = 0 }; int main (int argc, char **argv) { return 0; } I cannot think of a good way around this short of changing the collate constant name and re-building. The examples are boiled down and it would not be possible for me to change the order of the includes nor would it be easy remove the using delcaration.

problems with binary variant visitors in 1.31
by E. Gladyshev 06 Feb '04

06 Feb '04

Great job with the 1.31 release! Just wondering if anybody else observerved this kind of problems before. When compiling the code below with MSVC 7.1, I am getting this error: test.cpp(123) : error C2039: 'set' : is not a member of 'my_type::test1'. GCC 3.2.3 gives a compilation error as well. template< typename T > struct binary_variant_visitor : public ::boost::static_visitor<> { T& obj_; binary_variant_visitor( T& obj ) : obj_(obj) {} template< typename VT1, typename VT2 > void operator()( VT1& v1, VT2& v2 ) { obj_.visit( v1, v2 ); } }; struct my_type { struct test1 { test1(); ~test1(); }; struct test2 { ~test2(); template< typename T > void set( T& ); }; typedef ::boost::variant<test1,test2> var; var d_; template< typename U > void visit( test1& t, U& u ) //test1 doesn't have set() { } template< typename T, typename U > void visit( T& t, U& u ) { t.set(u); } const var& data() const { return d_; } }; main() { my_type t1, t2; binary_variant_visitor<my_type> v(t1); ::boost::apply_visitor(v, t1.data(), t2.data() ); } If I change the last line to ::boost::apply_visitor(v, t1.d_, t2.d_ ); it works fine on both compilers. I guess it has something to do with how apply_visitor derives the parameter types. Eugene __________________________________ Do you Yahoo!? Yahoo!

using lexical_cast with tuples.
by David Sankel 06 Feb '04

06 Feb '04

Hello, I'm guessing this has something to do with the unsetf(std::ios::skipws) call. Anyway, the following code seems contradictory since it's output is "Exception Thrown". Has anyone else come across this? #include <iostream> #include <boost/tuple/tuple.hpp> #include <boost/tuple/tuple_io.hpp> #include <boost/lexical_cast.hpp> int main() { boost::tuple<float,float> aTuple(2.2f,3.3f); std::string theString = boost::lexical_cast<std::string>(aTuple); try { boost::tuple<float,float> i = boost::lexical_cast<boost::tuple<float,float> > ( theString ); } catch(...) { std::cout << "Exception Thrown" << std::endl; } } Thanks, David J. Sankel

[BGL] Using undirected adjacency_matrix.
by Cromwell Enage 05 Feb '04

05 Feb '04

Morning, all. When the attached source code is compiled as is, the program works as expected. If the first #if condition is set to 0, the program garbles some output before crashing. If second #if condition is then set to 1, the program outputs much less, but it still crashes. Without the undirectedS property tag, the program works as expected, regardless of the #if conditions. I'm using the MinGW compiler bundled with Dev-C++ 4.9.8.5 and linking to the Boost libraries downloaded from CVS as of today, 0830 EST. I don't use the adjacency_matrix class template except for testing, so this is no showstopper, but it does seem to put a crimp on genericity. Feedback appreciated!

Boost suugestion
by Mohammed 05 Feb '04

05 Feb '04

Hi... I am facing a problem with Boost. It is not a big problem but takes a long time to do. I use more than one library from Boost. I need to create a text file that contains all the Boost libraries header files paths. Adding these paths everytime I compile with gcc is time consuming. I am working on Windows XP and Boost library 1.30.0 is installed on drive C:. Mohammed
