Hi All,
I'm using a simple program to test itoa() function in Red Hat 6.2. The program as follow:
////////test.c////////////
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
char buffer[20];
int base;
for( base = 2; base <= 16; base += 2 ) {
printf( "%2d %s\n", base,
itoa( 12765, buffer, base ) );
}
return EXIT_SUCCESS;
}
//////////////////////////
and then i compile:
gcc -o test.out test.c
but there is errorr:
/tmp/cci2KXGm.o: In function `main':
/tmp/cci2KXGm.o(.text+0x2c
collect2: ld returned 1 exit status
I use gcc 2.95.2, libc-2.1.3.so
Please help me.
Thank

hi,
u don't have a built-in library function for itoa in gcc in redhat Linux. so u will surely get this undefined reference to itoa error.
if u want to get rid od this error then u have to write a function called itoain the same program.
if u want a itoa converter program i can send it to u or just apply the logic given by Mr.Gavin to get the result.
regards,
Sri
I do believe that newmang is OLD, because I'm old and i don't recall itoa(), at any Rate, sprintf will work, or you can visit the code farm at www.sourceforge.com and pick a converter, many available.

newmang admits that he is OLD (I started working on computers with real core memories not these new fangled silicon memories we have these days and I well remember coding on paper tapes and punched cards).
But my memory remains intact - there hasn't been an itoa function but they are a snip to code anyway.
Cheers from the old folks home - gavin

I may be getting old and forgetful (According to my kids I am) but I can't recall an itoa function. atoi, atol etc I do use but not itoa. The gcc compiler on linux and cc compiler on Solaris don't have any reference to these functions either.
You can achieve the required result for base 8, 10 & 16 using the sprintf function but for the others you'll probably have to do it manually by repeated divisions by the base number.
