Hi all,
I successfully compiled the following test program for arm-elf under Cygwin
cross-GCC:
-----------------------------------------
#include <stdlib.h>
#include <stdio.h>
int main()
{
char *str ;
str=(char *)malloc(80) ;
strcpy( str, "hello world" ) ;
free( str ) ;
}
__gccmain(void)
{;}
-----------------------------------------
$ arm-elf-gcc -g test.c
This produced a working executable, which I could debug under GDB/Insight.
However, when I tried to use arm-elf-ld, I received the following error:
amit@AMIT ~/mallocTest
$ arm-elf-gcc -g -c test.c
amit@AMIT ~/mallocTest
$ arm-elf-ld -e0x8000 -o test test.o -lc
/home/amit/arm-elf/arm-elf/lib/libc.a(freer.o): In function
`_malloc_trim_r':
/home/amit/GNU_SRC/build-newlib/arm-elf/newlib/libc/stdlib/../../../../../ne
wlib
-1.9.0/newlib/libc/stdlib/mallocr.c:3270: undefined reference to `__udivsi3'
It seems to me like I'm missing something in the link command line.
Any help will be greatly appreciated.
P.S.
I'm using:
$ arm-elf-gcc -v
Reading specs from /home/amit/arm-elf/lib/gcc-lib/arm-elf/2.95.3/specs
gcc version 2.95.3 20010315 (release
$ arm-elf-ld -v
GNU ld version 2.11.2 (with BFD 2.11.2)
