我想用动态链接库做一个原生c程序，所以我把这些文件放在Android/development/hello/：hello.c，myprint.h，myprint.c，main()在hello.c，和Android.mk 是：
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := myprint
LOCAL_SRC_FILES := myprint.c
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := helloworld
LOCAL_SRC_FILES := hello.c
LOCAL_SHARED_LIBRARIES := myprint
include $(BUILD_EXECUTABLE)
然后我做helloworld，输出信息是：
target thumb C: helloworld <= development/hello/hello.c
target thumb C: myprint <= development/hello/myprint.c
target SharedLib: myprint (out/target/product/generic/obj/SHARED_LIBRARIES/myprint_intermediates/LINKED/myprint.so)
target Symbolic: myprint (out/target/product/generic/symbols/system/lib/myprint.so)
target Strip: myprint (out/target/product/generic/obj/lib/myprint.so)
target Executable: helloworld (out/target/product/generic/obj/EXECUTABLES/helloworld_intermediates/LINKED/helloworld)

development/hello/hello.c:5: error: undefined reference to 'myprint'
collect2: error: ld returned 1 exit status
请帮我...
我的本机代码是：
// hello.c
#include "myprint.h"
int main()
{
myprint();
return 0;
}
// myprint.h
void myprint();
// myprint.c
#include <stdio.h>
void myprint()
{
printf("myprint...\n");
}
