osx - C++11 headers missing on Mac OS X 10.8.2 (MountainLion) -

-

i'm new mac. have linux , windows c++11 source uses boost i'd build on mac. installed macport (should instead using homebrew?) ran commands such as:

sudo port install cmake sudo port install boost sudo port install openssl sudo port install gcc49 sudo port install gcc_select sudo port install --set gcc mp-gcc49

cmake correctly finds boost 1.57.0 , sets makefile. when run make, seems cannot find normal c++11 headers such "chrono":

in file included ../src/test.cpp:10: ../src/test_private.hpp:33:10: fatal error: 'chrono' file not found #include <chrono>          ^ 1 error generated.

indeed, when go looking c++ header files, see of them in /usr/include/c++/4.2.1/ newer files such chrono , thread missing.

is there package need install before can compile c++11 source code on mac?

xcode, apple supplied compiler/tools, comes 2 implementations of std::lib:

  1. gcc's libstdc++, version 4.2.
  2. libc++

the first very, old, , not support in c++11 such <chrono>. second supports c++11 quite well, can used clang, not gcc. clang comes xcode.

you need install command line tools after install xcode:

xcode-select --install

c++ - Delete matches in OpenCV (Keypoints and descriptors) -

-
i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
