runtime error R6002

anyone know why i would get a runtime error R6002
- floating point not loaded
in what seems like a fine program
it occurs at the point where the program attempts to read a file

Re: runtime error R6002

Hi Mick,

Please post the simplified code you have, so that we may take a look at it and tell you what is the error.

Here is an extract from MSDN about the error R6002:
Quote:

The necessary floating-point library was not linked.
Possible causes
  • The program was compiled or linked with an option, such as /FPi87, that requires a coprocessor, but the program was run on a machine that did not have a coprocessor installed.
  • A format string for a printf or scanf function contained a floating-point format specification and the program did not contain any floating-point values or variables.
  • The compiler minimizes a program's size by loading floating-point support only when necessary. The compiler cannot detect floating-point format specifications in format strings, so it does not load the necessary floating-point routines.
  • Use a floating-point argument to correspond to the floating-point format specification, or perform a floating-point assignment elsewhere in the program. This causes floating-point support to be loaded.
  • In a mixed-language program, a C library was specified before a FORTRAN library when the program was linked. Relink and specify the C library last.
-From MSDN.

Regards,
Paramesh.

Re: runtime error R6002

i had a double inside a struct that wasnt being seen by the compiler so i just created a 'dummy' double outside the structure to force the compiler to bring in the rest of sscanf, is this the best way to do this?

it got rid of the error msg anyway but now the program simply skips to the 'end of file found msg' without displaying the values contained in the .dat file.
very strange

Could you share your code with us, so that we can think about your question ?

Re: runtime error R6002

Hi Mick,

I have a question:
Did you print the variables?

After considering your previous thread, here is an example:
CPP / C++ / C Code:
...
...
...
        /*code....*/
    else
    if (line_ptr == NULL)
        printf( "End of file found\n");
    }

    /*print the variables here and see what you get..*/

    printf("id x    y\n");
    for( i = 0; i < no_nodes; i++)
    {
        printf("%d %.1lf %.1lf\n", node_array[i].id ,node_array[i].x ,node_array[i].y );
    }
Print after the lecturer's code you already have.

and according to your lecturer's code, it end of file found is printed, it indicates that we have got the values from the file and stored it in the variables node_array[i].

Regards,
Paramesh.

Re: runtime error R6002

Got it working again, i'd deleted a line of program when i started to get the runtime error to see if it was causing the problem, just had to put it back in. ive added a lot to the program, to make it a bit more user friendly and then made it able to write the data to a file aswell. its all working fine now and im currently just looking at converting it to use linked lists so ill let you know how that goes.
heres the program anyway, thanks for all the help paramesh, couldn't have done it without u.

Re: runtime error R6002

CPP / C++ / C Code:
#include <stdio.h>
int main(void)
{
char line[101], filename[101];
char *line_ptr;
double dummy = 9;

struct node
	{
	int id;
	double x, y, stress;
	};

struct node node_array[100];			
int no_nodes = 0, no_values, i;
FILE *input_stream, *output_stream;
fprintf(stdout, "Enter the file name you wish to read from: ");
fscanf(stdin, "%s", filename);
fprintf(stdout, "\nReading %s", filename);
    if ((input_stream = fopen(filename, "r")) != NULL)
			{
			fgets(line, sizeof(line), input_stream);
			while (((line_ptr = fgets(line, sizeof(line), input_stream)) != NULL) &&
			((no_values = sscanf (line, "%d %lf %lf %lf",
							&node_array[no_nodes].id,
							&node_array[no_nodes].x,
							&node_array[no_nodes].y,
							&node_array[no_nodes].stress)) == 4)) no_nodes++;
							fclose(input_stream);

			if ((line_ptr != NULL) && (no_values != 4))
				fprintf(stdout, "Error reading line %s\n", line);
			else
				if (line_ptr == NULL)
				fprintf(stdout, "\nEnd of file found\n\n");
				fprintf(stdout, "%s\n\n", filename);
				fprintf(stdout, "node x y stress\n\n");	        //colomn headers//	

			}
	else
		fprintf(stdout, "\nFile does not exist\n");
		

for( i = 0; i < no_nodes; i++)
    {
	fprintf(stdout, "%d %.1lf %.1lf %.1lf\n",
							node_array[i].id,
							node_array[i].x,
							node_array[i].y,
							node_array[i].stress );
	}


fprintf(stdout, "\nEnter the file name you wish to write to: ");
fscanf(stdin, "%s", filename);

((output_stream = fopen(filename, "w")) != NULL);
fprintf(output_stream, "node x y stress\n");
for( i = 0; i < no_nodes; i++)
		{
		fprintf(output_stream, "%d %.1lf %.1lf %.1lf\n",
							node_array[i].id,
							node_array[i].x,
							node_array[i].y,
							node_array[i].stress );
		}

fclose(input_stream);
fprintf(stdout, "\nData has been written to %s\n\n", filename);
return(0);
}

Re: runtime error R6002

Good job Mick.

But you can still improve your program by replacing
"fprintf(stdout" by printf and
"fscanf(stdin" by "scanf" statements.
