I just got confused. I must have tried something like template<class T> struct C { //no use of T here }; I think what the compiler is doing may actually be correct. (see 3.4.2 and 14.7.1). The standard was obviously not written with placeholders in mind. Actually there is an easy hack to make this work. Just add: struct boost::recursive_variant_ {}; In Christ, Steven Watanabe

29 Dec '06

Boost Inspection Report Run Date: 17:02:28 UTC, Friday 29 December 2006 An inspection program <http://www.boost.org/tools/inspect/index.html> checks each file in the current Boost CVS for various problems, generating this as output. Problems detected include tabs in files, missing copyrights, broken URL's, and similar misdemeanors. Totals: 11374 files scanned 888 directories scanned (including root) 183 problems reported Problem counts: 0 files with invalid line endings 0 bookmarks with invalid characters 4 invalid urls 116 broken links 22 unlinked files 4 file/directory names issues 2 files with tabs 0 violations of the Boost min/max guidelines 35 usages of unnamed namespaces in headers (including .ipp files) Summary:

Re: [boost] FW: [Boost-users] [variant] make_recursive_variant and std::map

It looks like a compiler bug introduced in sp1. Here is the simplest I could reduce it to. struct undefined; template<class T> void f(T) { } template<class T> struct A { }; template<class T> struct B { }; template<class T> struct C { T t; }; int main() { f((A<B<C<undefined> > >*)0); } This causes msvc to instantiate C<undefined>. Note that just B<C<undefined> > is not enough. All three templates are needed. Qualifying the call to f fixes the problem, so this bug appears to be caused by ADL. Now for your problem. The function calls that need to be qualified are visitation_impl_invoke and visitation_impl_invoke_impl in <boost/variant/detail/visitation_impl.hpp>. When I tried that it compiled. Until this is fixed you can use recursive_wrapper directly. struct my_map; typedef boost::variant<int, boost::recursive_wrapper<my_map> > element; struct my_map : std::map<float, element> { my_map(const std::map<float, element>& arg) : std::map<float, element>(arg) {} friend std::ostream& operator<<(std::ostream& os, const my_map& self) { os << static_cast<const std::map<float, element>&>(self); } }; In Christ, Steven Watanabe

[interprocess] Container requirements for Boost.Interprocess allocators
by Mathias Gaunard 29 Dec '06

29 Dec '06

The boost inteprocess documentation [1] says that all objects must be constructed-destroyed via allocator::construct and allocator::destroy functions when using the interprocess allocators. However, according to the draft of the next C++ Standard [2] 20.1.6/2, allocator::construct is strictly equivalent to placement new and allocator::destroy stricly equivalent to a call to the destructor, with the pointer type casted to void*. Therefore why is such a requirement necessary? [1] http://ice.prohosting.com/newfunk/boost/libs/interprocess/doc/html/interpro… [2] http://open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1905.pdf

[mpl] at for set and map does not match documentation
by Paul O'Neill 29 Dec '06

29 Dec '06

The map & set documentation all refer to the method "at" as having a default return value if no match is found, however I can only get the version without a default to compile and a look at the source at.hpp seems to indicate this is not implemented. Any help would be greatly appreciated. boost_1_33_1/libs/mpl/doc/refmanual/associative-sequence.html at<s,k>::type - works at<s,k,def>::type - does not compile (msvc8.0) Many thanks, Paul.

vs2005 sp1 released
by Michael Marcin 29 Dec '06

Hello, As RC_1_34_0 continues to progress towards a shippable state, the world stubbornly refuses to wait. Visual Studio 2005 service pack 1 was released a few days ago. I didn't see any mention of it here but I may have missed it. This is just a heads up in case the got overlooked to make sure it's being tested. http://msdn.microsoft.com/vstudio/support/vs2005sp1/default.aspx Thanks, Michael Marcin

[detail] sparc v8plus build problem
by Glenn Schrader 28 Dec '06

28 Dec '06

I have a strange build error when compiling for sparc solaris. In particular there are errors of the form: error: cannot use v8plus instructions in a non-v8plus target binary After a bit of digging the error is coming from the compare_and_swap function in boost/detail/sp_counted_base_gcc_sparc.hpp This function has some inline assembly that uses the "cas" (compare and swap) opcode. The sparc assembler is effectively complaining that the instruction isn't supported. If I manually hack the Makefile to give -sBUILD='<instruction-set>v9' to bjam then everything compiles properly. I think that boost/detail/sp_counted_base.hpp has a problem in the lines #elif defined(__GNUC__) && ( defined( __sparcv8 ) || defined( __sparcv9 ) ) # include <boost/detail/sp_counted_base_gcc_sparc.hpp> The cas instruction is supported on the sparc v8plus and v9. Support for just sparc v8 is inadequate. In that case you need to use the swap instruction and some looping to do something similar to a cas. Another wrinkle is that just removing the defined(__sparcv8) from the above condition doesn't quite do the right thing with gcc. From what I can tell gcc is setting __sparcv8 even if -mcpu=v9 is specified. I have a v9 processor but I'm running 32 bit solaris so could gcc be basing the __sparcv8/v9 defines on the OS rather than the cpu type? The biggest difference between the v8 and v9 cpus is 64bit support. Thanks, -glenn
