I have a simple assembly program that I am trying to compile, but ld cannot
resolve printf.
------
#movtest3.s - Example using index memory locations
.section .data
output:
.asciz "The value is %d\n"
values:
.int 10,15,20,25,30,35,40,45,50,55,60
.section .text
.globl _start
_start:
nop
movl $0, %edi
loop:
movl values(, %edi, 4), %eax
pushl %eax
pushl $output
call printf
addl $8, %esp
inc %edi
cmpl $11, %edi
jne loop
movl $0, %ebx
movl $1, %eax
int $0x80
#end of ASM
#Makefile
test:
as -o indexedMemory.o indexedMemory.s
ld --verbose -o indexedMemory indexedMemory.o -lc
#end of Makefile
Result is always:
....
attempt to open indexedMemory.o succeeded
indexedMemory.o
attempt to open /usr/bin/../lib/libc.dll.a failed
attempt to open /usr/bin/../lib/c.dll.a failed
attempt to open /usr/bin/../lib/libc.a succeeded
indexedMemory.o:fake:(.text+0x14): undefined reference to `printf'
make: *** [test] Error 1
#end of result
-------------
I've tried linking in numerous libraries, hoping one would resolve printf,
and in numerous order of where to include the -lxxx, but I can't get it to
compile. I've also tried it on numerous computers, including those with a
first-time fresh install of cygwin. Compiling a simple helloworld C program
works fine.
I've compiled the same program fine in linux using as/ld.
What am I doing wrong???
Thank you for any help,
- David
