  c++ templates compiler-errors
  Ive looked all over and I cant find anything relating to my problem. Im trying to write a class definition for a polygon class that basicly has a vector that holds pointers to a point.

  c++ compilation cplex
  I have a compilation problem using C++ language and IloCplex framework.I first tried to compile the entire project using a makefile, but i got an unexpected error, with a class header call AbstractModel, so as to ensure that this error is not due to other file, i decided to just compile this class with this command :g++ -o AbstractModel.o -c -I/path/to/cplex/include -I/path/to/concert/include -DIL_STD AbstractModel.cppThen i realized that i got the same error message, here is the AbstractModel c

  c++ rapidxml
  I’m having an issue with storing member variables that are of RapidXML datatypes. I also experience this problem with member functions’ return types.Only in the class’ file header to I experience this issue. Using these datatypes within functions yields no issues.class Level { public://Level();//~Level();sf::Sprite Update(Camera& _currentView);char* ReadFile(std::string& _level);xml_node<>* ParseFile(std::string _level, std::string _tileset);void BuildLayers(xml_node<>* _file

  c++ c comparison unsigned signed
  By “intuitive” I mean givenint a = -1; unsigned int b = 3;expression (a < b) should evaluate to 1.There is a number of questions on Stackoverflow already asking why in this or that particular case C compiler complains about signed/unsigned comparison. The answers boil down to integer conversion rules and such. Yet there does not seem to be a rationale behind why compiler has to be so exceptionally dumb when comparing singed and unsigned integers. Using declarations above, why expression like(

  c++ iostream
  I am reading a std::istream and I need to verify without extracting characters that:1) The stream is not “empty”, i.e. that trying to read a char will not result in an fail state (solved by using peek() member function and checking fail state, then setting back to original state)2) That among the characters left there is at least one which is not a space, a tab or a newline char. The reason for this is, is that I am reading text files containing say one int per line, and sometimes there may be e

  c++ function struct
  I’m learning about struct types in C++ and I tried to write a function that would change the values of the members of a struct type variable. However, it produces an unexpected output and I can’t figure out why this is happening. /Program to test struct types/#include <iostream> #include <cstring> using namespace std; struct myStruct {string a;string b;int c;float d; };void assignValues(myStruct myobj) {myobj.a = “foobar”;myobj.b = “Foo Bar”;myobj.c = 12;myobj.d = 15.223; } int main

  I’m going through exercises of a C++ book. For each exercise I want to minimize the boilerplate code I have to write. I’ve set up my project a certain way but it doesn’t seem right, and requires too many changes.Right now I have a single main.cpp file with the following:#include “e0614.h” int main() {E0614 ex;ex.solve(); }Each time I create a new class from an exercise, I have to come and modify this file to change the name of the included header as well as the class i’m instantiating.So my ques

  I have a script that compresses my css files and outputs the filename of the output file. I’m trying to build a makefile to automatize the process:all:@echo “Compiling CSS”CSS_OUTPUT=$(shell php minify_css.php )echo $(CSS_OUTPUT)I’m trying to store the output filename in CSS_OUTPUT variable, but I’m doing something wrong, as this whole makefile just prints:$ make abcdefg.css Compiling CSS CSS_OUTPUT= echo So output is not assigned to CSS_OUTPUT. Also, why is php output printed before the @echo “

  android linux makefile android-source prebuild
  I have glibc compiled for arm which is different from Android glibc or the bionic C as the glibc environment I have complied will help in providing more api’s. Now I can copy the glibc environment on /system/ folder while Android is running, and on doing chroot I can run my programs on glibc environment.Currently I am compiling glibc and Android separately and then tarring the glibc and copying it on Android emulator sdcard and then untarring it on /system folder and then doing chroot on /system

  variables recursion linker makefile
  Currently i am having problems with a makefile due to some unexpected recursion and the neccessary collection of filenames. I want to call recursively a Makefile in the root folder of my project and that one should go through every possible subfolder (and their subfolders…) with the goal to collect all files and write them to a variable to be used as “targets” or dependent files.For example: /Makefile goes through /Source, /Source/Boot and finds /Source/Boot/Boot.s (-> one target is therefore
