[lexical_cast][STLport 4.5.3][trunk] static assertion failed in boost/detail/lcast_precision.hpp
by Joaquín Mª López Muñoz 09 Oct '07

09 Oct '07

Compiling the following snippet in MSVC++ 6.5 + STLport 4.5.3 with the trunk #include <boost/lexical_cast.hpp> int main() { return 0; } results in ...\boost\detail\lcast_precision.hpp(79) : error C2027: use of undefined type 'STATIC_ASSERTION_FAILURE<0>' ...\boost\detail\lcast_precision.hpp(89) : see reference to class template instantiation 'boost::detail::lcast_precision<T>' being compiled [...] The offending asserion in boost/detail/lcast_precision.hpp is BOOST_STATIC_ASSERT(!is_specialized_bin || limits::digits + 0UL < ULONG_MAX / 30103UL && precision_bin > limits::digits10 + 0UL && precision_bin <= streamsize_max + 0UL ); This problem did not arise with Boost 1.34 because boost/lexical_cast.hpp did not use the newly created lcast_precision.hpp. Other assertions in lcast_precision<> seem to work OK, so looks like is this particular one that should be fixed only. I lack the skills to propose a patch myself, but I can locally try patches others may provide. Thank you, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

[circular_buffer] Patch for base_test
by Markus Schöpflin 09 Oct '07

09 Oct '07

Hello, attached patch makes base_test pass on Tru64/CXX. It contains two modifications to the test itself: 1. Change exception to std::exception, because Tru64 already has a struct called exception in the system header math.h. 2. Change vector<MyInteger> v(5, 10); to vector<MyInteger> v(5, MyInteger(10)); as the compiler prefers template <class InputIterator> vector::vector( InputIterator first, InputIterator last, const Allocator& = Allocator()); over explicit vector( size_type n, const T& value = T(), const Allocator& = Allocator()); otherwise.

How and where can I file bugs relating to Boost.System? I don't see a component Boost.System in Trac, and am wondering where I can see the bugs that have been filed and closed in that library. Thanks in advance! -- Dean Michael C. Berris Software Engineer, Friendster, Inc. [http://cplusplus-soup.blogspot.com/] [mikhailberis(a)gmail.com] [+63 928 7291459] [+1 408 4049523]

GTL - geometric template library - determining interest

> Hello, > > I am trying to determine interest to submit GTL to boost. > > History/Background > ================== > GTL is a geometric library that implements basic rectilinear, fixed > point 1D, 2D and 3D types. It was developed over the past decade > inside Intel's own EDA CAD department mainly to support advanced > physical design tools that create/check/manipulate the massive layout > that goes into our microprocessors. GTL comes from a codestream that > successfully weathered through several major microprocessor tapeouts. > The management agreed to pursue the open-sourcing of GTL via boost > (with the boost license) - with all the obvious benefits of doing so. > Comparison to other geometric libraries ============================= We are aware of the various other libraries available. What GTL brings to the table: * parametrized fixed-precision cartesian coordinates * industrial strength code base * directly usable on any user type via template traits - based on C++ concepts * massive capacity * bone-crushing speed * isotropic API * ease of use > Implemented Rectilinear Types > ========================================= > 1D Types: Interval > 2D Types: Point, Segment, Rectangle, Polygon, PolygonSet > 3D Types: Point3D, Segment3D, LayeredRectangle, RectangularPrism > Polygons ======== This is by far the most algorithmically advanced type and functionality that we have. 1. full set of boolean operations on polygon sets (or, and, subtract, xor, etc) 2. runtime (all n*log(n) or better) - it is at par or better than other implementations that we're aware of 3. ease of use - simple, intuitive API functions 4. no memory management required by user 5. providing polygon set type that's complete 6. isotropic API // example 1 // construct default empty polygons sets that will be rectangularized // in the given orientation (on demand) gtl::PolygonSet a(VERTICAL), b(HORIZONTAL), c(VERTICAL); a += gtl::Rectangle(4, 5, 60, 70); // add a rectangle to polygon set a a += gtl::Rectangle(gtl::Interval(20, 30), gtl::Interval(40, 100)); // construct a rectangle from 2 intervals, add it to a // .. similar additions to b and c // intersect a with b (with a boolean and) - subtract from it a rectangle, // bloat the north edges of the result by 55 units c += ((a * b) - gtl::Rectangle(10, 10, 2000, 3000)).bloat(NORTH, 55); std::vector<gtl::Rectangle> v; c.get(v); // populate v with the vertical rectangles that make up c > Isotropy > ======== > A variety of directional types in 1D, 2D, 3D with states like: LOW, > HIGH, NORTH, HORIZONTAL, UP, etc > A set of operations on these types like: forward(), backward(), > toward(), left(), turn(), perpendicular(), etc. > > All API functions are isotropic, i.e. they take arguments of > directions/orientations.

Relying on (&x)[1] pointing to y. It misses this one: template <typename T> class Point3 { T v[3]; public: T &operator[]( size_t i ) { return v[i]; } T &x() { return v[0]; } T &y() { return v[1]; } T &z() { return v[2]; } }; which in my view is the only way to fly. It has no run-time overhead (provided the trivial functions are inlined). It does not rely on non-standard or non-portable features. It's simple and easy to understand. It has the added benefit that the underlying representation is kept private, and all access done via member functions. The main drawback is the extra brackets. cout << p.x(); rather than: cout << p.x; Which is a pain, but I think the benefits are worth it. -- Dave Harris, Nottingham, UK.

Re: [boost] boost::exception questions

Well, I could do something like this: typedef boost::error_info<tag_errorno, tag_filename,tag_size,tag_width> error_t; throw error_t(1,"output.txt",100,200); If this error was common throughtout an application, this typedef would make the code more readable. Many boost components support variable number of template arguments. It would be trivial to implement I think. You could even default the template arguments, to shorten the expression even further, such as: typedef boost::standard_error<> standard_error_t; throw standard_error_t(); You could do this instead of the "ugly" macros that you have for the "_LINE_", "_FILE_" and "_FUNCTION_". >> Usage of the stream operator (<<) for data insertion. I like using (<<) for data insertion and see no reason to remove it.

[filesystem] Patch to improve CodeGear/Borland support
by Nicola Musatti 08 Oct '07

08 Oct '07

Hallo, Beman. The patch enclosed here: http://svn.boost.org/trac/boost/ticket/1304 improves support for the latest CodeGear compiler in the filesystem library. Let me know if you would like me to apply it myself, assuming you have no objections to it being applied in the first place, that is. Cheers, Nicola -- Nicola.Musatti <at> gmail <dot> com Home: http://nicola.musatti.googlepages.com/home Blog: http://wthwdik.wordpress.com/
