Thanks Slacker,

This is the code i compiled:

#include "sys/alt_stdio.h"# include "stdio.h"# include "string.h"# include "system.h"
int main()
{ 
  
char* msg = "Detected character\n";
FILE* fp;
char prompt = 0;
printf("Testing begin\n");
fp = fopen ("/dev/uart_0","r+");
if (fp)
{
   while (prompt!=0)
    {
        prompt = getc(fp);
        if (prompt=='t')
        {
            fwrite (msg,strlen(msg),1,fp);
        }
    }
    
    fprintf(fp,"closing\n");
    fclose(fp);
}*/
return 0;
}

In the system library, if the "small C library" is unchecked, the errors are:

/cygdrive/c/altera/91/nios2eds/bin/nios2-gnutools/H-i686-pc-cygwin/bin/../lib/gcc/nios2-elf/3.4.6/../../../../nios2-elf/lib/libc.a(closer.o)   In function `_close_r':
/cygdrive/c/altera/91/nios2eds/bin/nios2-gnutools/H-i686-pc-cygwin/bin/../lib/gcc/nios2-elf/3.4.6/../../../../nios2-elf/lib/libc.a(lseekr.o)   In function `_lseek_r':
/cygdrive/c/altera/91/nios2eds/bin/nios2-gnutools/H-i686-pc-cygwin/bin/../lib/gcc/nios2-elf/3.4.6/../../../../nios2-elf/lib/libc.a(openr.o)   In function `_open_r':

If the "small C library" is checked, the errors are:

undefined reference to `fopen'
undefined reference to `fopen'
undefined reference to `fopen'

Is there any mistakes in my code, or my project configuration?

Thanks in advanced!

This line looks suspect:

#include "sys/alt_stdio.h"

You only need this if you're using the alternative stdio functions provided by Altera...alt_putstr(), alt_printf(), etc.

You also could have some sort of transient issue with the SysLib. I assume you've tried cleaning/rebuilding it or just re-creating it, right?

Also, those error messages still look rather short? Are you sure you're including all of what the compiler is choking on?

Cheers,

That's right slacker, i've tried to clean and rebuild it, but the errors still remain.

Can you tell me more about the SysLib transient, and the compiler issues. Which mistakes i probably made?

When i am trying to built simple hello world programme but it is giving below error....!! can you please clarify the problem....
