Im making a program on eclipse(linux), and getting a bunch of errors...
type string couldn't be resolved
symbol std couldn't be resolved
unresolved inclusion <iostream>
invalid preprocessing directive #include
etc...
know whats going on? I'm pretty sure it must be something with configuration..?
I have written my program and it works when I keep everything in the header files, and then have my main. I am now splitting them up into implementation files, but Eclipse keeps giving me errors. It gives me error at every opening brace of the constructor and functions. It says on all of them "Redefinition of (name of constructor or method), Previously declared here." What am I doing wrong, because it works in the header file?
#include "KeyValuePair.h"
template<typename Key,typename Value>
KeyValuePair<Key,Value>::KeyValuePair()

C++ sort algorithm or library that can take input of a bunch of rows of data and then sort rows by an arbitrary defined order of one of the columns ... i.e., sort rows by value of the first column in this order (boba bobc bobe bobx) etc?

I know general C++, library but i cannot figure out DLL's.
I have 2 c++ source files to put into my eclipse project and also a header file. How do I compile all of it to make an .exe file?

View 3 Replies View RelatedI just re-installed my OS some days ago,which contained Visual Studio.But I don't want to use the VS any more(at least in my computer) as the interminable installing process.Then I take Eclipse as my C/C++ IDE by MinGW and CDT. My Java program need to load an DLL file which wrote by C.But when I generating the DLL file,I got some errors.It seems that the compiler cannot find the header files. By the way,I just want to implement the hello-world program in C and invoke it in the Java program.This is my Java testing program:
Code:
public class HelloWorld{ public native void printHelloWorld();
static{
System.loadLibrary("hello");
}
public static void main(String[] args){
new HelloWorld().printHelloWorld();
}
}
And this is the header file generating by "javah HelloWorld":
Code:
/* DO NOT EDIT THIS FILE - it is machine generated */#include <jni.h>/* Header for class HelloWorld */
#ifndef _Included_HelloWorld
#define _Included_HelloWorld
#ifdef __cplusplus
extern "C" {
#endif

I am having trouble setting up SFML 2.1 to run with the eclipse IDE for c++ development. I use MinGW for my compiler.
When I link my include folder, lib folder and dll's it will not run a simple SFML program.
This is my problem. What should I do to be able to compile this program?
View 7 Replies View RelatedSo this program I have to make keeps spitting out an error report when I try and run it. I am using eclipse C kepler.
The file it is supposed to read has the following text;
R1 N001 N003 20
R2 N002 N001 5
R3 N001 0 10
R4 N002 N003 10
R5 N003 N000 5
I1 0 N002 10
I have the following code
#include "../header/FileIO.hpp"
#include <fstream>
#include <stdexcept>
#include <iostream>
std::string FileIO::ReadTXT(std::string filePath){
std::ifstream input(filePath.c_str());
[Code] ....
When I run it in Eclipse, it does not open an SDL window, and simply says <Terminated> Test.exe [C/C++ Application]. I can build the project successfully, but it simply won't run. There are no errors displayed.
HOWEVER, if I replace the above code with the code below, it runs fine, and creates an SDL window.
#include "../header/FileIO.hpp"
#include <fstream>
#include <stdexcept>
#include <iostream>
std::string FileIO::ReadTXT(std::string filePath) {
std::string output;
return output;
}
To make things weirder, if I run it in debug mode, even with the first piece of code, it will run and open an SDL window.
On an unrelated note, what does " Can't find a source file at "e:pgiawsrcpkgmingwrt-4.0.3-1-mingw32-srcld/../mingwrt-4.0.3-1-mingw32-src/src/libcrt/crt/main.c"

This is my sample socket tcp ip program , problem here is when i give working ip address and port number, it is showing default ip address as 127.0.0.1 and it is Waiting on (1978=port number) i.e., "connection on %d...", SERVER_PORT.

after you have compiled a program can you run it without an IDE?

i am writing a function that takes a delimited string and splits the strings into it's respective words according to the delimeter.
1) iterate through string and store delimeter position in vector array.
2) iterate through again and use substr to split into words and store again in a vector.
I then have a dictionary file, and am comapring each values in the string with each in the dictionary, problem is that it overruns the loop and obviously gives a subscript out of range error.
Code:
#include <iostream>#include <fstream>
#include <vector>
using namespace std;
//Start with string inputString
//Find delimeters ::pos as ints and stores positions in vector <int> array
//Run though string using 'find' and seperate string by positions of char32s
//Build vector<string> array of individual words in string
//Open dictionary file and loop though testing each words in vector string array against each word in dictionary

Giving a dynamic array, we want to pass the array elements from a file. The first number in the file N gives us the array length. They follow N numbers, the actual elements of the array.
Three brothers are going to work in the shop of their father for a time. The shop is doing well and every day generates profit which the three brothers may provide. The brothers agreed that they would divide the total time in three successive parts, not necessarily equal duration, and that each one will be working in the shop during one of these parts and collects the corresponding profit on his behalf. But they want to make a deal fairly, so that one received from three more profit someone else. Specifically, they want to minimize the profit the most favored of the three will receive.
I first created a program that WORKS! with complexity O(n3).

Let's assume that we have the following input:
10
1 1 8 1 1 3 4 9 5 2
The ouptut should be 15 -> A = 1 + 1 + 8 + 1 + 1 + 3 = 15 , B = 4 + 9 = 13 , C = 5 + 2 = 7.
But the ouptut is 16!
How can I reduce the complexity of my first working! C code?
I have a service A, and an application B. Service A needs to launch application B only if it's not running currently. This can be easily done in Windows by calling GetExitCodeProcess function. I cannot find an equivalent method for doing so in Linux/Mac.
So my current code says:
system("open /Users/adsmaster/client/client &"); // to launch the application from the service in a new shell
I read that on a Linux-line machine you can use $ cal to get the exit value of the recently run process but I am not sure how can get the exit value of a particular process?
I am working on a parallel processing server/client app with a multi-threaded server and several data processing clients, each their own process. I am trying to optimize some of the parameters, such as the size of the chunks that are read, processed, and output, and also some of the timeout values and such. I can track the time to finish a given task well enough, but it would be really nice to be able to track the cpu use. When CPU use is near 100% (on all cores) for the entire run, that is a good sign. I have noticed that with some combinations of parameters, CPU drops quite a bit for long stretches, which is not such a good sign. This app process large input files (2.5GB-65GB so far) and needs to be stable for long periods of time.
Other than sitting and staring at the task manager all day, is there a good way to track/log the CPU usage over runs that take many hours? I know that there are some apps like Everest that chart CPU use, but it would be nice to have something that would write to the same log file I am already using for other program output.
