我想爲Android版本編譯ffmpeg。
但每次嘗試時,我都無法編譯ffmpeg的源代碼。
我認爲我的配置選項可能無效。適用於Android的FFmpeg編譯(配置,製作)
我用這個腳本進行配置。
#!/bin/sh
NDK_PATH=$HOME/android-ndk-r8
PREBUILT=$NDK_PATH/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86
LDFLAGS="-Wl,-T,$PREBUILT/armelf_linux_eabi.x -Wl,-rpath-link=$NDK_PATH/platforms/android-8/arch-arm/usr/lib \
-L$NDK_PATH/platforms/android-8/arch-arm/usr/lib -nostdlib $PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtbegin.o \
$PREBUILT/lib/gcc/arm-linux-androideabi/4.4.3/crtend.o -lc -lm -ldl"
COMMON_CONFIG="\
./configure --target-os=linux \
--arch=arm \
--enable-cross-compile \
--cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
--as=$PREBUILT/bin/arm-linux-androideabi-gcc \
--cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
--sysinclude=$NDK_PATH/platforms/android-8/arch-arm/usr/include \
--nm=$PREBUILT/bin/arm-linux-androideabi-nm \
--extra-ldflags=\"$LDFLAGS\" \
--extra-cflags=-I$NDK_PATH/platforms/android-8/arch-arm/usr/include \
eval "$COMMON_CONFIG"
if [ $? -ne 0 ]; then
exit 1
fi
我必須給編譯器一個新的頭文件路徑(由--extra-CFLAGS),因爲當我輸入「製作」,編譯器不知道哪裏是頭文件(如文件math.h,的ctime。 h)
使用此腳本進行配置並鍵入'make'後,我得到了這些錯誤。

是什麼問題?
我的配置有錯誤的信息嗎?或任何失蹤的國旗?
操作系統:Mac獅子
的Android NDK版本:Android的NDK-R8
我下載了它,它適用於我。 – manutd
