如何编译C code。使用NDK为Android设备（ARM）？ [英] How to compile C code using NDK for Android Device (ARM)?

问题描述

我需要执行以下步骤：

• 写一个简单的计数器，它不断在C / C ++
溢出后自行复位

• 编译并推动了code到手机通过ADB


• 运行它作为通过ADB外壳在后台定期执行

• write a simple counter that keeps resetting itself after overflow in C/C++
• compile and push that code into the phone via ADB
• run it as a regular executable in background via ADB shell

如何使用编译工具链NDK上述C code吗？我发现一对夫妇类似的链接，但他们都不给简单完成步骤这样做。

how to compile the above C code using NDK toolchain? I found a couple of similar links but none of them give simple and complete steps to do so.

如果有完整的步骤请参考我相同的链接。

If there is a link with complete steps please do refer me to the same.

编译环境：Ubuntu的，编译应通过控制台来完成不属于任何IDE

Compile Environment: Ubuntu, compile should be done via console not any IDE

推荐答案

您说得对，我犯了一个错误，我什至没有测试它，并给了我
同样的错误，是由于主的切入点，因为这还没有
改变，但我希望这对你的作品。反正检查符号表纳米，
在实时执行strace的，你甚至可以用gdbserver的。

You're right, I made a mistake, I had not even tested it and gave me the same error, is due to the entry point of the "main", as this has not changed but I hope this works for you. Anyway check the symbol table "nm", the real-time execution "strace", you can even use gdbserver.

#include <stdio.h>
int main (int argc, char *argv[])
{
        printf ("hello world");
        return 0;
}


export NDK_ROOT=your_ndk_path
export PATH=$NDK_ROOT/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin:$PATH
export CC=arm-linux-androideabi-gcc
export LD=arm-linux-androideabi-ld
arm-linux-androideabi-gcc -I$NDK_ROOT/platforms/android-18/arch-arm/usr/include -Wl,-rpath-link=$NDK_ROOT/platforms/android-18/arch-arm/usr/lib -Wl,-L$NDK_ROOT/platforms/android-18/arch-arm/usr/lib -Wl,-lc -o test test.c

If ld return with erros like "... ld: error: cannot open... : No such file or directory"
try this for your losed files:
ln -s $NDK_ROOT/platforms/android-18/arch-arm/usr/lib/crtend_android.o
ln -s $NDK_ROOT/platforms/android-18/arch-arm/usr/lib/crtbegin_dynamic.o
