My Proposal for GSoC
by Mukund Chandra 28 Mar '17

28 Mar '17

Dear Sir, I want you to review the draft of my proposal and suggest me what I should do so that I can work with this project. The project is Project 1 for Boost.Geometry about filtering of compare distance predicates. Here is the link for my Proposal Draft : https://github.com/MukundChandra/Programs-For-GSoC/blob/MukundChandra-patch…

[gsoc2017] Applying for Boost.Geometry Project 1
by NowhereMan 28 Mar '17

28 Mar '17

Hello, I wish to pursue a path in GSOC 2017 with boost, specifically Project 1 which involves optimization of compare distance predicates. My name is Cody Glassman, a first-year student at my local Community College in Southern California, on a path to obtaining my BS in Computer Science from the University of California system. I am currently working hard developing a concise, yet thorough competency test and am hoping to establish contact with a mentor. Thank you!

small_vector alignment
by Tobias Loew 28 Mar '17

28 Mar '17

Hi, I wanted to use a boost::container::small_vector for 64-bit aligned doubles (to be used with SSE): But it seems that the "small-buffer" has a fixed calculated alignment which only depends on the value-type and does not consider the alignment of the (dynamic) allocator. Is this intended or is it a bug in the implementation? best regards Tobias -- View this message in context: http://boost.2283326.n4.nabble.com/small-vector-alignment-tp4692694.html Sent from the Boost - Dev mailing list archive at Nabble.com.

[geometry] Documentation garbage (Re: [Boost-announce] [release] Boost 1.64.0 Beta 1)

I noticed, the package consists of intermediate files from docs generation process of Boost.Geometry: /libs/geometry/doc/doxy/doxygen_output/html_by_doxygen /libs/geometry/doc/doxy/doxygen_output/xml May I ask how documentation of individual library makes it into the package? /libs/geometry/doc/Jamfile.v2 calls our custom make_qbk.py script which is known to not to do any post-generation clean-ups of intermediate files. Shall we add such cleanup to make_qbk.py or it is not relevant for release process? Best regards, -- Mateusz Loskot, http://mateusz.loskot.net

[gsoc17]Dynamic Shortest Path Computation
by A.I 28 Mar '17

28 Mar '17

Hi, everyone, I am Donghyuk Kim, a Ph.D. Student at KAIST(Korea Advanced Institute of Science and Technology) in South Korea. I've been studying motion/path planning algorithm and I'd like to contribute to a specific algorithm, "Dynamic Shortest Path Computation" in Boost graph library as a google summer code project. It is a tree-based data structure for maintaining single-source to all destination shortest path. It is also known that it outperforms the recomputation of Dijkstra or A* where insertion and deletion of vertex/edge can frequently happen. Here you can check my brief CV including educational/programming background and my interests. https://www.linkedin.com/in/donghyuk-kim-54223355/ Most of my source codes (research/project-purpose things) are in a private repository by our policy, for this reason, the only thing I can share is the below one: https://github.com/aidyk/SGMP The concept of "Dynamic Shortest Path Computation" was originally introduced in [Fully Dynamic Algorithms for Maintaining Shortest Paths Trees] by D. Frigioni, et al. (http://dl.acm.org/citation.cfm?id=338900) I've already implemented a prototype for my research, but testing, coding style unification and much more c++ style modification are required for general purpose. I hope someone find it interesting and be a mentor in this journey. Thanks in advance!

Going insane trying to build boost for android
by Robert Dailey 26 Mar '17

26 Mar '17

How many months has it been of lost google searching, trying to beat b2 into submission. I have no idea at this point how to build boost for Android. Really hoping I get some help here... So to start, here are the versions I'm using: - Android NDK r14b - Boost 1.63.0 I'm doing all of this on Windows 10, through command prompt. I want to use clang and libc++ to build boost for API 15. I figure the easiest way is to generate a standalone toolchain using the NDK, so I did that first: > %ANDROID_NDK%\build\tools\make_standalone_toolchain.py --arch arm --api 15 --stl libc++ "C:\android\_toolchains\arm-api-15" This generated the appropriate toolchain (I think). I then temporarily added this location to PATH: > set PATH=C:\android\_toolchains\arm-api-15\bin;%PATH% Then I ran bootstrap: > bootstrap.bat --with-toolset=clang Then I tried to build boost itself: > b2 --toolset=clang cxxflags="-stdlib=libc++ -std=c++14" threadapi=pthread --prefix=..\boost_android_arm --builddir=./ target-os=linux define=BOOST_FILESYSTEM_VERSION=3 --without-python link=static runtime-link=shared threading=multi variant=release install -j8 However I get failures when it tries to run the clang command: 'C:\code\_third_party\boost_1_63_0\\clang38++.exe' is not recognized as an internal or external command I'm not sure why it's appending that absolute path (that's where my current directory is set to, and where boost source is). It should just be trying to use "clang++" but doesn't look like it is. >From the output, it looks like it's trying to use clang correctly I think: "clang++" -c -x c++ -stdlib=libc++ -std=c++14 -O3 -Wno-inline -Wall -pthread -stdlib=libc++ -std=c++14 -DBOOST_ALL_NO_LIB=1 -DBOOST_FILESYSTEM_VERSION=3 -DBOOST_THREAD_USE_LIB=1 -DNDEBUG -I"." -o "bin.v2\libs\wave\build\clang-linux-android\release\link-static\target-os-linux\threadapi-pthread\threading-multi\cpplexer\re2clex\aq.o" "libs\wave\src\cpplexer\re2clex\aq.cpp" Am I going about this all wrong? How in the heck can I build boost for android using the settings I specified above?

[SIMD] Pre-review questions
by Artyom Beilis 26 Mar '17

26 Mar '17

Hello, I have several questions regarding Boost.SIMD (for pre-review) 1. What is boost::simd::pack::storage_type I can't find it in documentation. Is it the "native register" like __m128i for pack<int,4>? If the answer is no, how do I get access to underlying type? 2. I can't find in documentation how to performs casts between different types: I see in docs split_low (actually after I grepped for _mm_unpacklo) but I failed to find how to use one - there is no documentation regarding conversion/casting operation or at least I failed to find one. 3. Is there more convenient way to perform basic saturated operation for example if I want to calc abs diff of two bs::pack<unsigned char,16> values a,b I need to write bs::saturated_(be::minus)(a,b) + bs::saturated_(bs::minus)(b,a) It is quite inconvenient especially when most of operations you want to do are saturated. 4. Why Boost.SIMD is restricted to C++11? Most of the stuff is implementable withing C++2003, it severely limits the usability of the library for existing projects that can't trivially switch to new C++ standard (and there are too many in the "real world" industry) Thanks, Artyom
