[serialization] ambiguous concrete polymorphic archives
by Kim Barrett 16 Mar '06

16 Mar '06

The archive concepts include an is_saving and is_loading typedef. For concrete polymorphic archive types, such as polymorphic_binary_iarchive, attempting to access these values results in a compilation error due to ambiguity - there are two accessible definitions, from different base classes, specifically detail::interface_iarchive<binary_iarchive> detail::interface_iarchive<polymorphic_iarchive>

[test] gcc-warning patch
by Juergen Hunold 16 Mar '06

16 Mar '06

Hi ! I've been playing around with Boost.Test and I'm very impressed. We use gcc's -pedantic option in our build environment and this found an extra semicolon at uni_test_suite.hpp at line 51. Full patch against current anon cvs attached. This is a minor glitch, but some people are fond of -pedantic. (that's why my colleague activated it :-)) Yours, Jürgen -- * Dipl.-Math. Jürgen Hunold !

[optional] from_optional
by Vaclav Vesely 16 Mar '06

16 Mar '06

Hi, There is common need of getting value from optional with possibility to define default value in case of the optional is uninitialized. I suggest two alternatives: optional<int> o; int i = o.get(123); // meber function get with additional parameter int j = from_optional(o, 123); // free function Both alternatives can be implemented simultaneously. What do you think about it? Regards, Vaclav

[ANN] xpressive 1.0 in CVS and File Vault
by Eric Niebler 16 Mar '06

16 Mar '06

I'm pleased to announce the availability of xpressive 1.0. This is the code that is currently in Boost CVS and will be part of Boost v1.34. It is also available as a separate download in the File Vault, and it works with Boost v1.32 and higher. xpressive is a regular expression template library that allows regexes to be strings or expression templates, and to nest and call each other recursively. Its interface is similar to TR1.Regex. Download: http://tinyurl.com/gjzap Documentation: http://tinyurl.com/882t8 -- Eric Niebler Boost Consulting www.boost-consulting.com

HP-UX aCC or boost problem?
by Ralf W. Grosse-Kunstleve 16 Mar '06

16 Mar '06

While trying to port Boost.Python to HP-UX using the native "aCC" compiler I ran into this issue: void foo() { enum udt_builtin_mixture_enum { builtin_to_builtin ,builtin_to_udt ,udt_to_builtin ,udt_to_udt } ; udt_builtin_mixture_enum value1 = builtin_to_builtin; // this works udt_builtin_mixture_enum value2 = 0; // this doesn't } % aCC -AA -c enum_init.cpp "enum_init.cpp", line 11: error #2144: a value of type "int" cannot be used to initialize an entity of type "udt_builtin_mixture_enum" udt_builtin_mixture_enum value2 = 0; ^ 1 error detected in the compilation of "enum_init.cpp". Is the compiler correct in rejecting the initialization with 0? Thanks! Cheers, Ralf P.S.: aCC: HP aC++/ANSI C B3910B A.06.01 [Jan 05 2005] __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

[test] compile error on floating point comparison
by Vladimir Prus 16 Mar '06

16 Mar '06

The last test results on msvc (RudbekAssociates, as well as huber-V2), have a failure in math library that seems to be caused by Boost.Test. See: http://tinyurl.com/hon2m Seems like "max" and "min" are defined as macros. Per max/min guidelines (http://boost.org/more/lib_guide.htm) I've fixed this with attached patch, and comitted it as obvious. Hope this will fix the issue. - Volodya

[serialization][tru64cxx] assertion failed at extended_type_info.cpp
by JOAQUIN LOPEZ MU?Z 16 Mar '06

16 Mar '06

Hello, As of recently, the serialization test of Boost.MultiIndex has begun failing in Compaq C++ for Tru64, the behavior being a failed asertion at tkmap::insert(): http://tinyurl.com/kfqfs The test used to work, but has hundergone a significant change that I've got the hunch might be related to its currently failing: previously all serialization tests were performed in a single translation unit named test_serialization.cpp, while now the code has been split (for reasons irrelevant to this discussion) into two files test_serialization1.cpp and test_serialization2.cpp. Does this ring some bell? I've scanned the net for more info, the only thing I found is a reference to the same assertion at: http://lists.boost.org/boost-users/2006/02/17253.php but there's no conclusive answer in that thread, alas. Any help much appreciated, thank you in advance, Joaquín M López Muñoz Telefónica, Investigtación y Desarrollo
