一、修改configure

修改前：

SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)'
LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)'
SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)'

修改后：

SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'  
LIB_INSTALL_EXTRA_CMD='$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"'  
SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)'  
SLIB_INSTALL_LINKS='$(SLIBNAME)'

二、执行configure

./configure --disable-yasm

三、脚本记录

1、可以编译64位和32位脚本

#!/bin/bash

ADDI_LDFLAGS="-fPIE -pie"

ANDROID_X86_64_CFLAGS="-march=x86-64 -msse4.2 -mpopcnt -m64 -mtune=intel"

build()
{
    make clean
    cpu=$1
    CFALGS=$2
    echo "build $cpu"
    echo "CFALGS $CFALGS"
    
    configure $cpu $CFALGS
    make -j4
    make install
}

build arm64
build armv7-a

2、可以编译全部平台CPU架构版本

#!/bin/sh

MY_LIBS_NAME=ffmpeg-3.3.9
MY_DIR=ffmpeg-3.3.9

# cd ./${MY_DIR}

#编译的过程中产生的中间件的存放目录，为了区分编译目录，源码目录，install目录
MY_BUILD_DIR=binary


NDK_PATH=/Users/tal/plugin/ndk/android-ndk-r15c

    CFALGS=$5


    TOOLCHAIN=${NDK_PATH}/toolchains/${HOST}-${TOOLCHAIN_VERSION}/prebuilt/${BUILD_PLATFORM}
    CROSS_PREFIX=${TOOLCHAIN}/bin/$4-

    # build 中间件
    BUILD_DIR=./${MY_BUILD_DIR}/${ANDROID_ARCH_ABI}

    echo "pwd==$(pwd)"

    #echo "-------------------------按任意键继续---------------------"

    #echo "-------------------------继续执行-------------------------"

    mkdir -p ${BUILD_DIR}   #创建当前arch_abi的编译目录,比如:binary/armeabi-v7a
    echo "创建目录："${BUILD_DIR}
    # cd ${BUILD_DIR}         #此处 进了当前arch_abi的2级编译目录

    # cd ../../
    echo "执行脚本之前，当前目录："$(pwd)
    
    # sh ../../${MY_DIR}/configure \
    # sh configure \
    sh configure \
        --disable-yasm \
        --prefix=${PREFIX} \
        --target-os=${TARGET_OS} \
        --arch=${ARCH} \

        --disable-decoders \
        --enable-decoder=aac \
        --enable-decoder=aac_latm \
        --enable-decoder=h264 \
        --enable-decoder=mpeg4 \
        --enable-decoder=mjpeg \
        --enable-decoder=png \
        --disable-demuxers \
        --enable-demuxer=image2 \
        --enable-demuxer=h264 \

        --enable-small


    make clean
    # make
    make -j4
    make install

    #从当前arch_abi编译目录跳出，对应上面的cd ${BUILD_DIR},以便function多次执行
        # cd ../../

    echo "-------------------$2 build end-------------------------"
}


# build armeabi
 build_bin arm armeabi arm-linux-androideabi arm-linux-androideabi ${ANDROID_ARMV5_CFLAGS}

#build armeabi-v7a
 build_bin arm armeabi-v7a arm-linux-androideabi arm-linux-androideabi "$ANDROID_ARMV7_CFLAGS"

#build arm64-v8a
 build_bin arm64 arm64-v8a aarch64-linux-android aarch64-linux-android "$ANDROID_ARMV8_CFLAGS"

#build x86
build_bin x86 x86 x86 i686-linux-android "$ANDROID_X86_CFLAGS"

#build x86_64
build_bin x86_64 x86_64 x86_64 x86_64-linux-android "$ANDROID_X86_64_CFLAGS"

3、可以生成一个so文件的脚本

#!/bin/sh

MY_LIBS_NAME=ffmpeg-3.3.9
MY_DIR=ffmpeg-3.3.9

# cd ./${MY_DIR}

#编译的过程中产生的中间件的存放目录，为了区分编译目录，源码目录，install目录
