Не удалось собрать ffmpeg для Android - PullRequest
0 голосов
/ 03 октября 2018

Я пытаюсь собрать исходники ffmpeg для Android, используя два разных подхода:

  1. https://yesimroy.gitbooks.io/android-note/content/compile_ffmpeg_for_android.html
  2. https://github.com/Khang-NT/ffmpeg-binary-android

Проблемаздесь я сталкиваюсь с несколько схожей проблемой в обоих подходах, поэтому я полагаю, что проблема не в этих сценариях, а в моей среде есть что-то не так.Вот выходные данные обоих сценариев сборки:

Для подхода № 1:

/home/hamed/dev/android-tools/android-sdk-linux/ndk-bundle/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/i686-linux-android-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 "conflog.txt" produced by configure as this will help
solve the problem.

Android X86 builds finished

И для подхода № 2:

checking how to print strings... printf
checking for style of include used by make... GNU
checking for arm-linux-androideabi-gcc... /home/hamed/dev/android-tools/android-ndk-r18/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc
checking whether the C compiler works... no
configure: error: in `/home/hamed/dev/projects/ffmpeg/ffmpeg-binary-android/build_scripts/opus-1.1.5':
configure: error: C compiler cannot create executables

Я даже попытался повторно загрузить NDK, опасаясь, что компилятор gcc был поврежден, но все равно появляется та же строка ошибки.

И это файл config.log из модуля OPUS второгоподход:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by opus configure 1.1.5, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure -v --prefix=/home/hamed/dev/projects/ffmpeg/ffmpeg-binary-android/build_scripts/build_dir --host=arm-linux-androideabi --enable-static --disable-shared --disable-doc --disable-extra-programs

Как видно из журнала, двоичные файлы gcc в NDK r18 не являются GCC;они лязгGCC не поддерживается в NDK уже несколько лет и был окончательно удален в NDK r18.Чтобы обеспечить некоторую совместимость в тех случаях, когда проект прекрасно скомпонован с помощью Clang, но просто не обновил свои сценарии сборки, мы используем некоторые сценарии с именем gcc, которые просто вызывают Clang с правильным набором аргументов.

configure:3576: /home/hamed/dev/android-tools/android-ndk-r18/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc -mfloat-abi=softfp -marm -march=armv7-a -Os -O3   -I/home/hamed/dev/projects/ffmpeg/ffmpeg-binary-android/build_scripts/build_dir/include --sysroot=/home/hamed/dev/android-tools/android-ndk-r18/platforms/android-16/arch-arm/ -fPIE  --sysroot=/home/hamed/dev/android-tools/android-ndk-r18/platforms/android-16/arch-arm/  -L/home/hamed/dev/projects/ffmpeg/ffmpeg-binary-android/build_scripts/build_dir/lib -fPIE -pie  conftest.c  >&5

Ошибка здесь в том, что эти скрипты-обертки не включают -gcc-toolchain так, как им нужно.Я только что подал https://github.com/android-ndk/ndk/issues/805, чтобы отследить это.

Однако, даже если это исправлено, похоже, что этот проект не будет построен в любом случае:

clang: error: unknown argument '-qversion', did you mean '--version'?
clang: error: no input files

I 'Я не уверен, что это вызывает тот сценарий сборки, который вы используете, или это система autoconf, используемая ffmpeg, но что-то здесь нужно исправить, если оно будет работать с NDK r18.Наилучшим вариантом, вероятно, является использование автономного набора инструментов .
