C++ :: Makefile Options To Compile For 64 Bit
Mar 17, 2014
I have called a C function inside C++ code. The .so which gets created is a 32 bit while I am looking for 64 bit . What all options should be mentioned in the Make file to eventually compile and get shared object of ELF64 CLASS ?
Excerpts from Makefile
-----------------------------
CC = gcc
CXX = g++
CPPFLAGS = -I. -I$(S) -DHAVE_CONFIG_H
CFLAGS = -O2 -pipe
CXXFLAGS = -g -O2
LDFLAGS =
LIBS = -lsocket -lnsl

use makefiles, how to create a makefile with cpp files and the binary file in different directories.
These are my directories:
Project/
|
|-makefile
|
|__src/__.cpp files
|
|
|__bin/__ .exe
|
|
|__inc/__ .h files
|
|
|__obj/__ .o files
I have done this:
CC = g++
CFLAGS = -I.
SRCDIR = src
OBJDIR = obj
BINDIR = bin
INCDIR = inc
SOURCES := $(wildcard $(SRCDIR)/*.cpp)
[Code] .....
but console says "no rule to make target main.cpp, needed by project"

How do I check for ldconfig in a makefile? This makefile errors because it tries to run ldconfig, even though OS = Darwin
Code:
ifeq ($(SHARED),1)
install: banner install_headers $(lib_target)
@echo "Install shared library"
cp -f ./$(lib_target) $(inst_path)
cd $(inst_path) ;
[Code] ....
Errors
Code:
/bin/sh: -c: line 0: syntax error near unexpected token `Darwin,Darwin'
/bin/sh: -c: line 0: `ifneq (Darwin,Darwin)'
make: *** [install] Error 2
make: ldconfig: No such file or directory
make: *** [uninstall] Error 1

I would like to call a script from a makfile to glean some information about the OS. What I more or less need is the OS name and version (CentOS-5.9, OPENSUSE-12.2, Cygwin, etc). I think I can get the rest of what I need from uname. The OS name and version doesn't seem to reside in any consistent place over the various Linux flavors. I also need to get the version of the gnu c compiler, since I think that may also require a bit more involved scripting than I would like to try out of make.
The main question is weather I can call a script out of make and have it return a value for a variable.
Something like,
OS := $(shell ./script_name)

I have the following private part of a class defined as follows:
private:
struct stats {
double ISIsum;
int authorCount;
bool operator<(const stats &a) const { return ISIsum > a.ISIsum;}
} *stats_;
bool compareSortByISI(const stats &lhs, const stats &rhs);
};
This enables me to sort this struct by calling:
std::sort(stats_, stats_ + authors_->getMaximumAuthors());
My question is, what if I want to have the option to sort by authorCount or ISIsum at run time. Is there any way to do this?
I can't see how I can override operator< twice and decide which one to call at use time.

I have been reading up, and it seems that all I need to do to finish up the installation of a library is to add in the search path for the library upon compile time.
Of course, I also read that directly copying the lib files can work too, but that may result in the over-writing of necessary files...
I read a more thorough document on mingw's linking processes and discovered that I could create a folder, install the library in that folder, and add the folder as a search path for mingw (so, basically, all i have to do is install all my libraries under that folder).

I am having problems with setting up a menu as a function. The point of the menu is to display a list of 4 options and the user is supposed to choose one option and then the program will run. I am having trouble understanding how to display the menu once I run it because it is not working.
#include <iostream>
using namespace std;
int menu(int ans); // function declaration for menu
void draw_triangle(int size, char ch); //function declaration for triangle
void draw_downtri( int size, char ch); // function declaration for upside-down triangle
void draw_diamond(int size, char ch); //function declaration for diamond

Is there a way to access the router settings via c++? My friend wanted me to write something that would turn off wifi broadcasting on his router when pressing the button in the program. The only way I can think about is to connect to the router via .net framework and then use reverse engineering (on the router settings site) to find a way how to simulate change of option via POST or GET method.

I'm giving the replace option to my string:
void replace(string oldstring, string newstring) {
int stroldstringpos=b.find(oldstring);
b.replace(stroldstringpos,newstring.length(),newstring);
}
i have 1 error in these function that i'm confused. imagine the newstring size is more big than the oldstring, how can change the string, but only change the oldstring and add what left?
see these:
String test="hi hello world";
test.replace("hi","hello");
the result must be:
hello hello world
how can i change the replace function for it?

I am new to coding and have a question with my if else statement. This is a VERY simple program that I have made something like in Javascript before, but when I do it in C++ it does not work correctly. It displays both the options. Here is my code.
// Practice.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include <iostream>

I want to run the following code from the command line:
Code:
#include <iostream>
using namespace std;
#ifdef ABC
const int num = 105;

But I can not activate the ABC macro from the command line.
I'm trying to use the -d ABC option following the .exe file name, but I could not run the ABC macro.
How can I activate the ABC macro when I run the .exe file from the Windows 7 command line?

I decided to create a simple program to display a menu with options, while that is easy enough I had some difficulty when selecting an option that has options inside which also has an option again. While I had many issues in the past I'm finally finished with it and it works fine, but being new to programming and not knowing various other methods available.
Code:
//:::::::::::::::::::::Simple Menu Program::::::::::::::::
//::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#include <iostream>
#include <string>
//function prototypes

I need a program that has a login system and then a menu that has 3 options: Add, delete and exit. If I choose Add it wil ask for certain data of 5 students.
Then after registering the 5 students, another menu with the options: Search, Delete and exit. In search it will ask for an ID and then prints all the data of a single student. Delete gives me the option to delete the data of any user I choose.

My project is to make a options menu for the user to select a shape and than draw out the shape. That whole process is already done and ready to go. What i am having trouble on is totaling the number of selected shapes. For example, at the end of the program i need to prompt a message saying ("You have selected "shape" this many times "number").
