我正在尝试使用ndk为android编译ffmpeg。操作系统:ubuntu 13.10。我遵循了这个教程。但是当我运行build_android.sh时，它给了我以下错误-
sujith@Vaio:~$ cd /home/sujith/ndk9d/sources/ffmpeg
sujith@Vaio:~/ndk9d/sources/ffmpeg$ sudo chmod +x build_android.sh
[sudo] password for sujith:
sujith@Vaio:~/ndk9d/sources/ffmpeg$ ./build_android.sh
/home/sujith/sujith/ndk9d/toolchains/arm-linux-androideabi-4.8/prebuilt/linux- x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

这是我的build_android.sh
#!/bin/bash
NDK=$HOME/sujith/ndk9d
SYSROOT=$NDK/platforms/android-9/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
function build_one
{
./configure

build_one
我的build_android.sh位于ffmpeg源根目录。如何解决这个问题?
看来，NDK=$HOME/sujith/ndk9d是错的。应该是
NDK=$HOME/ndk9d
I had the same problem , and i dig into it and found that.
#!/bin/bash
NDK=$HOME/sujith/ndk9d
SYSROOT=$NDK/platforms/android-9/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
Step 1 : Verify all the above path.
Step 2 : Remove all the escape sequence and carriage return like below
#!/bin/bash
NDK=$HOME/FFMPEG/android-ndk/
SYSROOT=$NDK/platforms/android-24/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
function build_one
{
./configure --prefix=$PREFIX --enable-shared --disable-static --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-avdevice --disable-doc --disable-symver --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- --target-os=linux --arch=arm --enable-cross-compile --sysroot=$SYSROOT --extra-cflags=-Os -fpic $ADDI_CFLAGS --extra-ldflags=$ADDI_LDFLAGS $ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install
}
CPU=arm
PREFIX=$(pwd)/android/work
ADDI_CFLAGS="-marm"
build_one
Step 3 : As i can see in the your terminal
sujith@Vaio:~/ndk9d/sources/ffmpeg , you have kept the code in here .
But i have copied the source code directly in folder sources/
I didn't put the code inside any other folder. ./Configure file and build_android.sh are present in the sources/ folder with libavcodec etc folder and code.
Please try this and let me know if it solves your problem
