warning:internal error

[skb_mys]

hello.I am getting warnings called " warning:internal errorut of range error" when i built the program which is a mixture of c and assembly language. A part of it where i am getting the warning is given below

unsigned char lookup()
{
int i,j;
int k=0;
int index[num_d];
float dif[num_d];
...
...
for(i=0;i<num_d;i++)
{
if(dif[i]<0.01)....warning:internal error:out of range error
{
index[k++]=i;
}
}

so wherever there is use of array i am getting this warning and also in the lines given below

void anl(int xx)
{
p1=fir1(xx,p1);....same warning
p2=fir2(xx,p2);....same warning
}


unsigned char min(float a[num_d])
{
float smallest;
unsigned char ii;
unsigned char index;

index =0;
smallest = a[0];

for(ii=1;ii<num_d;ii++)
{
if(a[ii]<smallest).......warning-internal error:out of range error
{
smallest=a[ii];
index = ii;
}
}

index++;
return index;
}

float calcorrelation(int a[size_dic], int b[size_dic])
{
int ii;
float meanx1=0;
float r;
for (ii=0; ii<size_dic; ii++)
{
meanx1 = meanx1 + fix2float(a[ii]);.............///warning-out of range

}
r=size_dic*meanx1;...........same warning

r=1-r;
}

if (r < 0).......................////warnin-out of range
{
r = -r;
}
return r;

can someone plz help me..

Comparing floating point variables is, I think, causing the problem. Try appending 'f' to make it a float for eg.

if(dif[i]<0.01f);

Post something small, COMPLETE and without any of your .... paraphrasing the problem.

If you want to highlight a specific line, then put something like
/* error foo on this line */

You also need to say WHICH compiler you're using.
Good compilers rarely barf on simple programs with an "internal error" message. That means your compiler is broken, not necessarily your code.

[EVOEx]

What is num_d? If it's not a constant, then your code is wrong (this is allowed in C++0x, not in C/C++). Because the size of the array isn't known at compile time. It would be a horrible error message should this be true, though.

[Elysia]

C++0x does not allow non-constant array sizes to my knowledge...
And it is supported in C99.

ok.Below i have given a portion of problem

#define num_dic 5
#define size_dic 40
Main(void)
{
   unsigned char ii;//[0-256]
   int jj,kk=0;
   unsigned char result,temp;
   float  differ[num_dic];
   int  tmp_array[size_dic];
   float diffeuclid[num_dic];
   unsigned char rangeindex[num_dic];   // store the code with large coefficients
   
   for (ii=0;ii<num_dic;ii++)
   {
     differ[ii]=0.0;      
     diffeuclid[ii]=0.0;
   }
   
   for( ii=0; ii < num_dic; ii++ ) 
   {                             
      for(jj=0;jj<size_dic;jj++)
      {
          tmp_array[jj]=dic[ii][jj];
      }
      differ[ii]=calcorrelation(tmp_array, word);
      
   }

    }
    
    if (((size_dic*meanx2-meanx1*meanx1)==0) && ((size_dic*meany2-meany1*meany1)==0) ) )  /*warning:internal error-out of range error*/

       r = 0;
    else 
    {    
       r=(size_dic*meanxy-meanx1*meany1)*(size_dic*meanxy-meanx1*meany1)/(size_dic*meanx2-meanx1*meanx1)/(size_dic*meany2-meany1*meany1) )  /*warning:internal error-out of range error*/

Is this your real code?
You have a lot of mismatched ( and ), and ; placed at wrong places.
And main returns int. Not nothing.

hello.I am getting warnings called " warning:internal errorut of range error" when i built the program which is a mixture of c and assembly language.

Notice the part where it says internal error? The problem is not your code, but the compiler's ability to handle it. Basically, your compiler sucks.

[Elysia]

Yes, get yourself a new compiler while you're at it.
List of some IDEs
Assuming you're on Windows, I would recommend Visual Studio.

> Main(void)
main is also in lower case.

And you STILL didn't mention which compiler you're using.

It's not Miracle-C by any chance is it?

[skb_mys]

Hmmm.Sorry its a big program.I just gave a small portion of program.So while 'cut and paste and modify' operation a few 'so called miracles' peeped in. I am working on avr microcontroller and am using AVR STUDIO 4.16.So is the problem with the compiler.?will it affect the desired output..?

> Sorry its a big program.I just gave a small portion of program.
Like I said earlier, the ACTUAL code which generates the problem.

Do NOT post the whole program. Make a copy, and start deleting lots of code away from the error messages until you get down to a SMALL AND COMPLETE program which still generates the error message.

It could be anything which causes those errors. Maybe for example, you have ALL the code in some massive single source file, and these are a few lines right at the end of the file.

When you have your nice short file, you can then raise a bug report with the maintainer of the compiler.

If you do have a single large source file, and making it smaller allows it to compile, then you need to split your code up into multiple source files.

I'm also assuming that since you said "big program" that it actually worked OK just recently, and that you made some unrelated change (say adding another function), and now you're getting these errors in code which used to work.
