Compile error when initializing class member std::function? - c++

I am trying to create a class with an std::function member:
# include<functional>
class Widget {
public:
std::function<int(double)> call_foo;
Widget(std::function<int(double)> call_func)
: call_foo(call_func)
{};
};
However, when I try to initialize the class my code fails:
const int f(double x){
if(x > 5.0){
return 22;
}
return 17;
}
int main()
{
std::function<int(double)> f1 = f;
Widget p(f1);
}
The full set of errors is below:
tmp/ccDoRHCh.o: In function `__static_initialization_and_destruction_0(int, int)':
widget.cpp:(.text+0x109): undefined reference to `std::ios_base::Init::Init()'

collect2: error: ld returned 1 exit status
I am compiling with C++ 11 enabled.

Chances are either you forgot
#include <functional>
or you'r not compiling in C++11 mode.

instance = new Calendar();
return instance;
}
private:
static Calendar * instance; // Singleton variable
};
Anyone know where could be a problem?
Thank you
There is a collision between variable name Time and the class Time.
static double Time;
Rename the Time to some other variable.
static double MyTime;
You should compile the file with the Calendar class first:
g++ -std=c++0x -pedantic -Wall -Wextra Calendar.cpp -o calendar.o
and then try to link it with simims.cpp:
g++ -std=c++0x -pedantic -Wall -Wextra calendar.o simims.cpp -o simims

gcc Linker and OGDF "undefined reference to `ogdf::Initialization::Initialization()'"

I am trying to get OGDF working to see if it is suitable for my project, but I am having trouble with a sample program.
I am trying to compile this example program:
#include <ogdf/basic/Graph.h>
#include <ogdf/basic/graph_generators.h>
#include <ogdf/layered/DfsAcyclicSubgraph.h>
using namespace ogdf;
int main()
{
Graph G;
randomSimpleGraph(G, 10, 20);
DfsAcyclicSubgraph DAS;
DAS.callAndReverse(G);
G.writeGML("test.gml");
return 0;
}
using this command:
$g++ -pthread -I ./OGDF/ -L ./OGDF/_release/ -lOGDF test2.cpp
But I get the following error

I tried compiling hello world, with an include from OGDF, and I still got:
undefined reference to `ogdf::Initialization::Initialization()'
I think I am not linking properly or something?
You have to be very careful in which order you type stuff when linking with a library.
Try putting test2.cpp before -lOGDF instead, like this:
g++ -pthread -I ./OGDF/ -L ./OGDF/_release/ test2.cpp -lOGDF
You must build your program using the -DOGDF_DLL when using OGDF as a shared library.

Calling R function from C++ on Windows

I am trying to call R functions from C++ on Windows. I am using MinGW for compiling the program, but it throws error while compiling. Code (taken from Dirk) and compilation error are as follows:
#include <iostream>
using namespace std;
#include "RInside.h" // for the embedded R via RInside
Rcpp::NumericMatrix createMatrix(const int n) {
Rcpp::NumericMatrix M(n,n);
for (int i=0; i<n; i++) {
for (int j=0; j<n; j++) {
M(i,j) = i*10+j;
}
}
return(M);
}
int main(int argc, char *argv[]) {
const int mdim = 4; // let the matrices be 4 by 4
SEXP ans;
RInside R(argc, argv); // create an embedded R instance
Rcpp::NumericMatrix M = createMatrix(mdim); // create and fill a sample data Matrix
R["M"] = M; // assign C++ matrix M to R's 'M' var
std::string evalstr = "\
cat('Running ls()\n'); print(ls()); \
cat('Showing M\n'); print(M); \
cat('Showing colSums()\n'); Z <- colSums(M); print(Z); \
Z"; // returns Z
ans = R.parseEval(evalstr); // eval the init string -- Z is now in ans
Rcpp::NumericVector v(ans); // convert SEXP ans to a vector of doubles
for (int i=0; i< v.size(); i++) { // show the result
std::cout << "In C++ element " << i << " is " << v[i] << std::endl;
}
return 0;
}

Any ideas what I am missing?
Jim is correct in his earlier answer, but there is more.
When using RInside , you also need to
include and link with Rcpp (which RInside depends upon) a
include and link with R (which both depends upon) as well as of course
RInside's own library
The easiest way of doing this is to simply use the Makefile from the examples/standard directory --- given that you copied the code of one of the examples, you should also copy the build instructions.
Lastly, and that is your biggest issue: RInside applications do not currently work on Windows, which is clearly documented on the RInside page. It will build, but segfault on startup. Debugging help would be appreciated, this works on OS X and Linux.
You're not actually linking in the R library (whatever that is).

GCC 4.5.2 Linker gots Problem while using Exceptions (C++)

I try to write a webserver. As far as I am, it works quiet good with Windows. But I want to make it also Unix compatible. And I think there has to be a problem with the heredity f the exception class.
For better understanding, just the important parts:
server.cpp
#include <exception>
#include <stdexcept>
#ifdef __unix__
#include "UnixSocket.h"
#elif __WIN32__ || _MSC_VER
#include "WinSocket.h"
#endif
#include "HTTPParser.h"
int main(void) {
try {
socket->socketInit(PORT);
}
catch (exception &e) {
cout << endl << "Exception: " << e.what() << endl;
socket->cleanAll();
}
return 0
}
NetInterface.h
class NetInterface : public exception {
private:
public:
virtual void socketInit(const char *port) = 0;
virtual void cleanAll(void) = 0;
virtual void cleanPersCon(void) = 0;
virtual char *akzeptieren(void) = 0;
virtual void empfangen(void) = 0;
virtual void senden(void) = 0;
virtual void *get_in_addr(struct sockaddr *sa) = 0;
virtual string getIncoming(void) = 0;
virtual void setOutcoming(string s) = 0;
virtual ~NetInterface() throw() {};
};
UnixSocket.h
class UnixSocket : virtual public NetInterface {
private:
[...]
public:
UnixSocket(void);
//kill socket connections
void cleanAll(void);
void cleanPersCon(void);
//SysCalls
void socketInit(const char *port);
char *akzeptieren(void);
void empfangen(void);
void senden(void);
//Getter and Setter
string getIncoming(void);
void setOutcoming(string s);
virtual ~UnixSocket() throw() {};
};
HTTPParser.h
class HTTPParser : public exception {
private:
[...]
public:
HTTPParser(NetInterface *_socket, string _path);
void parsePacket(void);
virtual ~HTTPParser() throw() {};
};
There you can se a short summary of the class declarations.
But now the gcc tells me something like this:

and even more....
Judging from undefined reference to __gxx_personality_v0 linker message it looks like you are linking with gcc. You need to link C++ applications with g++. Or link with gcc and add -lstdc++ to the linker command line.
You aren't showing the relevant code and compiler invocation, but know that std::exception has an unimplemented virtual member function what() that you're expected to override, so don't go throwing naked std::exceptions if you want to callwhat().
Any of the derived, specific exceptions in <stdexcept> will implement what() and allow you to store a message when you're constructing the exception object.

LEDA-6.3 library

I am a leda-6.3 library user.
I used graphwin to manipulate and display graphs, but I found that references
to graphwin methods are undefined while compiling the code although they
are declared in the LEDA/incl/LEDA/graphics/graphwin.h
So I think it is a problem of object file.
#include <LEDA/graphics/graphwin.h>
#include <LEDA/graph/graph_alg.h>
using namespace leda;
int main()

GraphWin gw("LEDA Graph Editor");

node v=gw.new_node(point(100,200));
gw.new_edge(u,v);
gw.display();
gw.get_window().read_mouse();
graph& G=gw.get_graph();
G.new_node();
gw.get_window().read_mouse();
gw.update_graph();
gw.get_window().read_mouse();
return 0;

Which edition of LEDA are you using?
Please consider that free edition of LEDA does not contain GraphWin.
So, it dos not contain GraphWin libraries, which results to getting such errors while compiling your program.
