Hello every one
I have a tool.S like this
.text
.align2
.global asm_call
asm_call:
mov r0 , #0
mov r1 , #1
and I wrote a test.c like this
#include <stdio.h>
void asm_call();
int main(int argc , char **argv)
{
asm_call();
}
My make file like this
LOCAL_PATH :=$(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE := test
arm_src_files := tool.S
LOCAL_SRC_FILES := test.c
LOCAL_SHARED_LIBRARIES :=libdl
include $(BUILD_EXECUTABLE)
when I run mmm ./external/test
there is an error said : error undefined reference to 'asm_call'
I'v tryed to add 'extern' before 'asm_call' in c code like this : extern
void asm_call() , and the result remain the same .
Can any one give me some advise ?
Thanks.
