C :: Library Of Functions - Getting Error At Compile Time
Nov 19, 2013So I made a library for a whole bunch of functions and when i compile it, it says"Unresolved external symbol_(Name of function here) referenced in function main.

View 11 Replies View RelatedIs there any possible way of calculating some values at compile time? I have the following code of genereting upto 2000000010 palindrome numbers.
Code:
#include <iostream>
#include <string>
#include <sstream>
#include <string.h>
#include <stdlib.h>
[Code] .....
As you see, I have taken input from the user just after calculating the whole palindromes. So cant we calculate this at compile time? because runtime of this program is extremely slow.
Another qs. I first tried to use array but It didnt allow 2*10^9 sized array. so what should I do whenever I need that size of array?
My question is this: Is it possible to determine where functions are stored at compile time, so that at run time you can pass the memory address as a pointer to the interrupt handler so that it can directly call the function at memory location 'X'?
The newest project I'm working on would require to either somehow capture these addresses or to find a work-around so that instead of passing the pointer to the interrupt handler, the software would then need to be able to be non-interruptable.
Would there be anyway for the compiler, or the language, to provide a unique ID during compilation?
I've been using UUID generators, but I've always found the approach of copy pasting from a program to code to be kind of... limiting. If I want a random number, can't the compiler guarantee this for me?
It already does the same thing for anonymous namespaces, so...
Consider:
Code: template<unsigned int N>
class Test
{
private:
[Code]....
I just cannot understand why (clearly, we are calling <0, 0>, not <0, 8>). If I replace "N" with 8, it works as expected (at least for the beginning of the loop). I only tested on MSVC.
I am working on a project, where I have to be able to exclude some code fast and dynamicly at compiletime.
I got a scheduler running and actually I just want to remove some of the tasks from it - but at compile time so that the code wont take up space in my microcontroller.
I know that I can use macros like #ifdef #endif etc. But I think that method makes the code unreadable and complicated.
How to archive such functionality a more elegant way?
I would like to have a program with a 5 mb string embedded in it kind of like this:
Code:
const char *c;
c = (const char*)"BEGIN_STRING_HERE, (5 MB of arbitrary values here)";
Is it possible to generate this string at compile time? Maybe with a macro? I'm trying to avoid a source file with a 5 mb string in it.
How do I set the size of a member array via the class constructor if I know the size at compile time. I can do this with templates, see below, but this leads to code bloats, I think.
So one class declaration but objects with different array sizes.
Can't use constexpr.
Can't use STL.
Can't use new.
#include <iostream>
using namespace std;
template<int T>
class MyArray {
private:
int array[T];
public:
int getSize()

I want to generalize my productFunction below to a template family of functions where the template merely changes the * to + or whatever else operator I wish to use.
#include <iostream>
#include <functional>
#define show(variable) std::cout << #variable << " = " << variable << std::endl;
template <typename, typename...> struct ProductFunction;
template <typename RETURN_TYPE, typename FIRST, typename... REST>
struct ProductFunction<RETURN_TYPE, FIRST, REST...> : ProductFunction<RETURN_TYPE, REST...> {
const FIRST function;
using Base = ProductFunction<RETURN_TYPE, REST...>;

How can I turn a template parameter into various operators? (apart from using switch statements that will reduce the performance and make the code really ugly) What kind of metatemplating method converts a compile-time constant to an operator?

I wrote a binary function based on existing template:
template <class T> struct percentage : binary_function <T,T,double> {
double operator() (const T& x, const T& y) const
{return x*1.0/(x+y);}
};
I call it in form of percentage<int>() When I compile, it's indicated: error C2143: syntax error : missing ',' before '<' I use VC 2012.
i was working to compile the code below. Unfortunately it didn't compile and give me the known error error: attempt to use poisoned "calloc".
This is how i compile it :

I am trying to compile some code under opensuse 12.2. The code compiles fine under cygwin and CentOS. Under suse, I get the error "directory name must immediately follow -I"
This is the place in make where the error happens.
Code:
g77-3.3 -I ./src/src_common_depend/ -O2 -DVERNUM=6 -c -o bld_dir/FortranA.o src/src_client_main/FortranA.FOR
f771: error: directory name must immediately follow -I
The includes are specified in the make file with,
SOURCELOC = ./src
INCLUDES = -I ${SOURCELOC}/src_common_depend/
These are common includes that are used by more than one applications and so are stored in a common location.
I have tried leaving off the ./ and the trailing /
SOURCELOC = src
INCLUDES = -I ${SOURCELOC}/src_common_depend
And various similar combinations, including parenthesis instead of the curly braces.
I'm not sure why gcc under suse would be particular about this syntax when gcc under other distros seem to think it's fine.
This is the compile rule that g77 is implementing where the error occurs:
# compile src fortran objects with fortran preprocessor
$(BDIR)/%.o: $(SOURCELOC)/src_client_main/%.FOR
$(FCOMP) $(FCFLAGS) $(VFLAGS) -c -o $@ $<
The below code compiles without error using VS 2012 but with g++ 4.1.2 I get this error:
Code:
main.cpp: In function 'int main(int, char**)':
main.cpp:37: error: no matching function for call to 'StringHelper::stringToNumeric(std::basic_string<char, std::char_traits<char>, std::allocator<char> >)'
Here is the code:
#include <string>
#include "boost/lexical_cast.hpp"
using boost::lexical_cast;
using boost::bad_lexical_cast;
class StringHelper {
[Code] ....
This is part of a larger program so in reality StringHelper has more static functions but this example does produce the error the same as the code when in the larger program.
To get it to compile under g++ I had to assign the return value from substr() to a string and pass that string to stringToNumeric. Why do I have to do this for g++ and not VS? Do I have something wrong with my template function that g++ is calling out and VS is not?
I want to know how to list the all the symbols in the shared library(dll or .so file). I dont want commands like nm or objdump or depends.exe . I want to get the list of functions available in shared library programmatically at runtime (after calling loadlibrary/dlopen and GetProcAddress/dlsym). Is there a way to get the complete signature of functions in a shared library?

Okay so I'm writing a simple program - so far with just 1 header and 1 .cpp file to go with it. I'm getting strange errors saying that my struct hasn't been recognised even though I declare it in the header. The code involved is --
Code:
#include<stdio.h>
#include<iostream>
#include<sstream>
#include"bots.h"
//#include"prisonersDilemna.h"
//write program to battle multiple bots with a random choice generator
//and after all iterations post who comes out on top.
[Code] ....
||=== Build finished: 6 errors, 0 warnings ===|
How should the syntax be? Why does my program not recognise bot as an object type? Why can I not have a void method?

Why I might be getting that? I have the .lib in the depends line, and the directory where it is at in the include line.
