[config] BOOST_NO_CXX11_HDR_MEMORY and gcc-4.6.2

Hi, I'm checking for BOOST_NO_CXX11_HDR_MEMORY to include <memory> file with gcc-4.6.2 C++0x and while the file is there (it was a C++98 file),it is not defining in particular pointer_traits and allocator_traits Could the following patch be applied?

[1.55] Request permission to merge 86426 to branches/release
by Beman Dawes 28 Oct '13

28 Oct '13

86426 needs to be merged to branches/release. It is a showstopper since without it all msvc tests are broken. It is a one-liner from Steven that simply deletes line 15, " : usage-requirements <implicit-dependency>/boost//headers" from libs/Jamfile.v2. This was was part of a three revision set of patches (86393, 86398, and 86426) that was being held waiting for trunk tests to cycle. The first two got merged yesterday, but the last one was missed in the last minute rush. --Beman

[config] gcc 4.6 unified initialization syntax buggy
by klaus triendl 28 Oct '13

28 Oct '13

hi, gcc 4.6 (with -std=c++0x) has a bug in its support for unified initialization. specifically a derived class cannot initialize its base with members, if the base has no user-defined constructor: <code> struct base { int i; }; struct derived: base { explicit derived(int i): base{i} {} }; </code> therefore the configuration macro BOOST_NO_CXX11_UNIFIED_INITIALIZATION_SYNTAX should be fixed... Has this been already addressed? -- klaus triendl

[numeric] Lack headers for ARM CPU
by christine bouzant 28 Oct '13

28 Oct '13

Hello all, I would need to include the header boost/numeric/interval/hw_rounding.hpp but i see that the ARM CPU is not taken in account. Is someone would have a non official header version for the ARM cpu case ? Thank you! Cheers, Christine

boost::polygon type genericity
by T. Raykoff 28 Oct '13

28 Oct '13

boost::polygon has a nice facility for generic numeric types for coordinate values via coordinate_traits, etc. But there are a number of places in the library code where a hard-coded type, usually a double, is used instead of referring to the appropriate type in this trait struct. Should this be considered a bug in b::p? Background: I'd like to use a custom class as a type which manages the scaling of real-world decimal coordinates to the integral values that b::p likes to use. I understand the whole thing about snap-rounding to an integral grid and all that, so need to scale up the real-world decimal values to an appropriate grid size. But it makes sense to carry this paradigm through to all of the typedef's in coordinate_traits and high_precision_type, but this is where things break with the hard-coded double's.

[git] [conversion] Schedule and remaining showstoppers?
by Beman Dawes 27 Oct '13

27 Oct '13

It seems to me the best time for the svn to modular git changeover is right after a Boost release. That will give us the maximum time window to get the new house in order before the subsequent release. So should we convert right after 1.55 ships? I'm well aware that there is a long list of conversion related tasks that we haven't completed. But the svn -> git conversion process itself is so complex that only Dave and Daniel can make modifications. They have done a staggering amount of work already and are nearing exhaustion. Once the conversion is done, there are many of us that understand git well enough to help with problems. For example, https://github.com/ryppl/Boost2Git/issues/5, "Mimic gitfow", is a showstopper in that what is now "master" should be "develop" and the true "master" (i.e. releases) branch needs to be synthesized. But while it would be great if the Boost2Git process could handle that, it could probably also be do by a post-conversion step performed by git and other command line tools that many of us could help with. Messy, but I'm not willing to take a further delay waiting for perfection. Which of the issues in https://github.com/ryppl/Boost2Git/issues?state=openare true show stoppers? Are there any true showstoppers missing from that list? --Beman

Hi!
