对于 C 应用程序的编译链接,自己编写的 makefile 是件比较困难的事情,我们可以利用 NDK 提供的 build 工具,实现我们的目标。
比如我们以hello.c工程:
#include <stdio.h>
int main()
{
printf("Hello World!\n");
return 0;
}
编写Android.mk文件
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE:= helloa
LOCAL_SRC_FILES := hello.c
include $(BUILD_EXECUTABLE)
在当前目录下打开终端运行:ndk-build,出现如下错误:
[D:\ndk\android-ndk-r9d\sources\hellotest]$ ndk-build
Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.
D:\ndk\android-ndk-r9d\build/core/build-local.mk:148: *** Android NDK: Aborting . Stop.
解决办法有两种:
1)在该路径下创建一个空白的AndroidManifest.xml文件
<?xml version="1.0" encoding="utf-8"?>
<manifest/>
再次执行ndk-build,可顺利编译出可执行文件,adb push到android平台上执行:
[D:\ndk\android-ndk-r9d\sources\hellotest]$ ndk-build
[armeabi] Compile thumb : helloa <= hello.c
[armeabi] Executable : helloa
[armeabi] Install : helloa => libs/armeabi/helloa
2)根据提示,可进行NDK_PROJECT_PATH赋值指定:
ndk-build -B NDK_PROJECT_PATH=.
再次执行ndk-build,同样可顺利编译出可执行文件,adb push到android平台上执行:
[D:\ndk\android-ndk-r9d\sources\hellotest]$ ndk-build
[armeabi] Compile thumb : helloa <= hello.c
[armeabi] Executable : helloa
[armeabi] Install : helloa => libs/armeabi/helloa
