本文介绍了臂的Linux androideabi-GCC是无法创建可执行文件 - 编译的ffmpeg为Android armeabi设备的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想编译的ffmpeg为Android armeabi设备。
我下面的教程由 roman10.net
他给出构建脚本生成的ffmpeg对ARMv7-A设备。我想建立它armeabi。

我的最终目的是运行在Android armeabi和ARMv7-A设备的ffmpeg的命令。

所以我剧本的CPU部分改变从

  #arm v7vfpv3
CPU =的ARMv7-A
OPTIMIZE_CFLAGS = -  mfloat-ABI = softfp -mfpu =的VFPv3-D16 -marm -march = $ CPU
preFIX =。/安卓/ $ CPU
ADDITIONAL_CONFIGURE_FLAG =
build_one

到

  #arm V6
CPU =的ARMv6
OPTIMIZE_CFLAGS = -  MARM -march = $ CPU
preFIX =。/安卓/ $ CPU
ADDITIONAL_CONFIGURE_FLAG =
build_one

（我认为这改变用于ARMv6将建立与ffmpeg的armeabi设备兼容。M I错了吗？）

疑点1：
难道我也有改变工具链？
即从 ARM-Linux的androideabi-4.4.3 为 ARM-EABI-4.4.0 ?????

疑点二：

当我尝试运行运行./build.sh（不改变工具链），它给了我下面的错误：

<$p$p><$c$c>/home/chaitanya/android/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/$p$pbuilt/linux-x86/bin/arm-linux-androideabi-gcc无法创建一个可执行文件。 C编译器测试失败。 如果你想配置犯了一个错误，.. blaah blahh blaah

之后，我得到了很多警告说的：
sub_id是德precated等诸多功能去precated警告。

平台：Ubuntu的11.10
的ffmpeg版本：0.11.2
NDK ：Android的NDK-R5B

下面是我的构建脚本：

我该如何解决这个问题？什么错误？

解决方案

我不知道这是你在找什么，但我为了打造的FFmpeg 0.11.1为Android创造了一个脚本。我修改规定与旧Bambuser FFmpeg的建立，以便脚本，让他们与0.11.1工作。我目前使用这个脚本在我自己的应用程序建立FFmpeg的，所以我知道的构建工作。位于<一个脚本href="http://servestream.sourceforge.net/build-ffmpeg.sh">http://servestream.sourceforge.net/build-ffmpeg.sh.我使用的Andr​​oid NDK，R8B和Ubuntu 12.04（64位）做建设。为了使用该脚本执行以下操作：

1）下载脚本
2）打开脚本，然后修改包变量，以匹配应用程序的包
3）把它变成可执行的：chmod + X build-ffmpeg.sh
4）设置脚本使用NDK的变量，例如：出口NDK = /家庭/用户/ Android的NDK-R8B
5）运行该脚本：./build-ffmpeg.sh

在编译的二进制文件将设在新创建的最终构建文件夹中的当前工作目录。 （注：脚本生成的二进制文件armeabi，armeabi-V7A和x86体系结构）

我希望这回答了你的问题。

I am trying to compile ffmpeg for android armeabi devices.
I am following tutorial by roman10.net
His given build script builds ffmpeg for armv7-a devices. I want to build it for armeabi.

My ultimate aim is to run ffmpeg commands on android armeabi and armv7-a devices.

So I change the script's CPU part from

#arm v7vfpv3
CPU=armv7-a
OPTIMIZE_CFLAGS="-mfloat-abi=softfp -mfpu=vfpv3-d16 -marm -march=$CPU "
PREFIX=./android/$CPU
ADDITIONAL_CONFIGURE_FLAG=
build_one

to

#arm v6
CPU=armv6
OPTIMIZE_CFLAGS="-marm -march=$CPU"
PREFIX=./android/$CPU 
ADDITIONAL_CONFIGURE_FLAG=
build_one

(I thought changing it to armv6 would build ffmpeg compatible with armeabi devices. m I wrong?)

Doubt 1:
Do I also have to change toolchain?
i.e from arm-linux-androideabi-4.4.3 to arm-eabi-4.4.0 ?????

Doubt 2:

When I try running ./build.sh (without changing toolchain) it gives me following error: 

/home/chaitanya/android/android-ndk-r5b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake,.. blaah blahh blaah

after that I got lot of warnings saying:
‘sub_id’ is deprecated and many other function deprecated warnings.

platform: ubuntu 11.10
ffmpeg version: 0.11.2
NDK : android-ndk-r5b

Here is my build script:

How do I tackle this problem? what is going wrong?

解决方案

I'm not sure if this is what you are looking but I created a script in order to build FFmpeg 0.11.1 for Android. I modified the scripts provided with older Bambuser FFmpeg builds in order to get them working with 0.11.1. I'm currently using this script to build FFmpeg in my own application so I know the build works. The script located at http://servestream.sourceforge.net/build-ffmpeg.sh. I'm using android-ndk-r8b and Ubuntu 12.04 (x64) to do the building. In order to use the script do the following:

1.) Download the script
2.) Open the script and modify the PACKAGE variable to match application's package
3.) Make it executable: chmod +x build-ffmpeg.sh
4.) Set the NDK variable used by the script, for example: export NDK=/home/user/android-ndk-r8b
5.) Run the script: ./build-ffmpeg.sh

The compiled binaries will be located in the newly created "final-builds" folder in the current working directory. (Note: the script builds binaries for armeabi, armeabi-v7a and x86 architectures)

I hope this answers your question.
