so you want to compile your program with the c compiler?

then you have to select c at the new project wizard....

(or save your file as .c because c::b distinguishes c and c++ files by their extension...)

Also, need to change the CB Compiler config to link with the gcc instead of g++ command.

Ok, one more question: what is the preferred method of installation of GSL for working with Code::Blocks in Windows 8?

C++


--- Code: ---#include <stdio.h>
#include <cstdlib>
#include <gsl/gsl_sf_bessel.h>
#include <iostream>
#include <sstream>
#include <fstream>
using namespace std;

int main()
{
    /*Summing a bunch of numbers*/
    int numero, somma;
somma=0;
printf ("Insert a number other than 0 in the sequence, otherwise 0 to end the insertion\n");
scanf ("%d", &numero);
while (numero != 0)
{
somma=somma+numero;
printf("Insert a number other than 0 in the sequence, otherwise 0 to end the insertion\n");
scanf("%d", &numero);
}
printf("The sum equals: %d\n", somma);

/*GSL Bessel function*/

    double x = 5.0;
    double y = gsl_sf_bessel_J0(x);
    printf("J0(%g) = %.18e\n", x, y);

    /*Writing to a text file*/

    FILE *tab1;
tab1=fopen ("somma.txt","w");

fprintf(tab1, "%d", somma);
fclose (tab1);

/*Writing to a csv file*/

ofstream tab2("tabela.csv");

double A; int t;
    tab2 << "Col 1;Col 2" << endl;
    for (t = 0; t <= 10; t++) {

      A = t+somma+y;

      cout << "t = " << t << "\t\tA = " << A << endl;
      tab2 << t << ";" << A << endl;
    }
    tab2.close();

    /*End*/
    system("PAUSE");
    return 0;
}

Try reading the FAQ on the wiki and especially this page: http://wiki.codeblocks.org/index.php?title=FAQ-Compiling_%28general%29#Q:_I_would_like_to_compile_a_project_using_some_non-standard_libraries._How_can_I_indicate_to_CodeBlocks_that_these_libraries_and_include_files_exist.3F

Also read the manual of your compiler and understand how it handles #includes.
And lastly try to understand what is the difference between "" and <> in the include directive.

BlueHazzard:
And always post the full build log if you want some help...

greetings
