# How to compile C++ hello world with Android NDK
|
|
|
|
1. Create following directory structure:
|
|
|
|
```
|
|
hello_world/
|
|
jni/
|
|
libs/
|
|
```
|
|
|
|
2. In the `jni` directory create two files
|
|
1. Android.mk:
|
|
|
|
```
|
|
LOCAL_PATH := $(call my-dir)
|
|
include $(CLEAR_VARS)
|
|
|
|
# give module name
|
|
LOCAL_MODULE := hello_world
|
|
|
|
# list your C files to compile
|
|
LOCAL_SRC_FILES := test.c
|
|
|
|
# This seems to be needed for Android M on ARMv8
|
|
LOCAL_CFLAGS = -fPIE
|
|
LOCAL_LDFLAGS = -fPIE -pie
|
|
|
|
include $(BUILD_EXECUTABLE)
|
|
```
|
|
|
|
2. test.c
|
|
|
|
```
|
|
#include <stdio.h>
|
|
#include <stdlib.h>
|
|
int main()
|
|
{
|
|
printf("Hello World\n");
|
|
return 0;
|
|
}
|
|
```
|
|
|
|
4. Export PATH to NDK
|
|
```
|
|
export PATH=/usr/local/softs/android-ndk-r10e:$PATH
|
|
```
|
|
3. Go to `jni` directory
|
|
5. Call ``ndk-build``
|
|
6. Result should be in `hello_world/libs/armeabi/hello_world`
