Force definition of symbol for a C++ template instance in a library -

i'd provide library provides template code. keep possible ownership of code (generated code) when can guess usage of different usual types of template. here example of trying do: lib1.h #include <iostream> template<int n> void print_me() { std::cout << "i function number " << n << std::endl; } lib1.cpp #include "lib1.h" /* force symbols defined here. */ template void print_me<0>(); template void print_me<1>(); i compile library using: g++ -shared -fpic lib1.cpp -o lib1.so and when use library: main.cpp #include <lib1.h> int main() { print_me<0>(); print_me<1>(); print_me<2>(); } compiled with: g++ main.cpp -l1 here expect symbol print_me<0>() , print_me<1>() defined , used lib1.so , print_me<2>() defined , used executable (checked nm --defined-only). seems not case! symbols 0 , 1 defined in lib1.so weak symbols. , redefined

i new c# , attempting read in .csv file , put each line of text in separate list item can sort later. the .csv file organised so: 1;"final60";"united kingdom";"2013-12-06 15:48:16"; 2;"donnyr8";"netherlands";"2013-12-06 15:54:32"; etc this first attempt doesn't work.it shows no errors in visual studios 2010 when run console program displays following exception instead of list. exception of type 'system.outofmemoryexception' thrown. bizarre because .csv file contains small list. try { // load csv file using (streamreader file = new streamreader("file.csv")) { string line = file.readline(); list<string> filelist = new list<string>(); // lines file until end of // file reached. while (line != null) { filelist.add(line); } foreach (string filelistline in filelist) { console.wri

javascript - Filter json data in controller, the right way -

(there other questions neither helped me out) hi, know if right way filter results service i'm displaying 1 result (like detail). i know use ng-repeat , filter in view , cleanest, want have more control on because re-use of data in controller other operations. right i'm doing this: $scope.savedevents = event.getpayedevents(); //gets list service //goes through entire list , checks match angular.foreach($scope.savedevents, function(event) { if (event.idevent == $stateparams.eventid) { $scope.showevent = event; } }); //now if there match can use $scope.showevent.eventname etc not sure if easier using $filter return 1 event has correct idevent. or if has better solution, please let me know. thanks i don't see problems have, inject $filter service , 1 liner: $scope.showevent = $filter('filter')($scope.savedevents, { idevent: $stateparams.eventid }); edit: here easy way resolve result single value returned array: var sh

How do I use C preprocessor macros with Rust's FFI? -

i'm writing code interfaces existing library written in c. in rust code i'd able use values cpp macros. if have c include.h looks this: #define init_flag 0x00000001 i'd able use in rust this: #[link(name="mylib")] extern { pub static init_flag: c_int = init_flag; } i've looked @ other ffi code , see lot of people duplicating these values in rust instead of getting them ffi. seems little brittle, , i'd able handle more complicated things defined via cpp macros. running cpp on rust files work if i'm sure cpp macros used simple things. it impossible, , don't think possible in future. c macros bring many problems them. if want run cpp on rust sources, can manually. if don't want , if there lot of constants , don't want copy values c code rust can make c wrapper provide global variables these values: #define init_flag 0x00000001 ... const int init_flag = init_flag; you compile file, create static library , link

c++ - Using a local short to pass a value into a function expecting an int; does this save memory? -

i'm on embedded system (for first time) , have whopping 512 bytes of memory. i'm bumping against barrier, , i'm looking save on each , every byte possible. such, following question: in sdk, there's function, prototyped: void foo(int val); as such, main looked like: void main() { int myval = 0; // stuff compute myval foo(myval); } myval, however, never have value more ~100. saving memory @ doing instead? void main() { short int myval = 0; // stuff compute myval foo(myval); } edit: on architecture, ints 4-bytes, shorts 2-bytes. i'm unsure of whether using local short (or char, or whatever) save space since has up-cast meet foo(int) prototype. i have no experience such small systems; following guess (the smallest ones worked had 384 k). changing int short or makes compiler's optimizer work, , optimizer's output cannot predicted 100% accuracy. your platform has sort of convention passing parameters f

javascript - Timeout in Jquery to update the Dom? -

let's want change image source onclick , calculations. whats happening right source changes when the function exits. (dom busy?) how can make image source updates right away , function proceeds while loop? html: <img src="http://goo.gl/l55g2p" id="imagesrc"> js: $( "#imagesrc" ).click(function() { new_imgsrc="http://goo.gl/wbhyee"; $("#imagesrc").attr('src',new_imgsrc); test = 0 { test = test + 1; console.log(test); } while (test != 50000); }); here 's jsfiddle. not sure understand correctly use timeout: settimeout(function() { //while loop here }, 1000); where 1000 means 1 second. shrink value doesn't wait long. as click() has no callback oncomplete not sure of better way achieve this.

c++ - Is there a penalty for using static variables in C++11 -

in c++11, this: const std::vector<int>& f() { static const std::vector<int> x { 1, 2, 3 }; return x; } is thread-safe. however, there penalty calling function after first time (i.e. when initialized) due thread-safe guarantee? wondering if function slower 1 using global variable, because has acquire mutex check whether it's being initialized thread every time called, or something. "the best intution ever had 'i should measure this.'" let's find out : #include <atomic> #include <chrono> #include <cstdint> #include <iostream> #include <numeric> #include <vector> namespace { class timer { using hrc = std::chrono::high_resolution_clock; hrc::time_point start; static hrc::time_point now() { // prevent memory operations reordering across // time measurement. overkill, needs more // research determine correct fencing. std::atomic_thread_fence(std::mem
