ndk编译faac生成库

1.编译脚本如下：

NDK=/opt/android-ndk-r9d
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
export PLATFORM=$NDK/platforms/android-/arch-arm/
function build_faac
{
pwd
CFLAGS="-fpic -DANDROID -fpic  -mthumb-interwork -ffunction-sections -funwind-tables -fstack-protector -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__ -Wno-psabi -march=armv5te -mtune=xscale -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -DANDROID -Wa,--noexecstack -MMD -MP "
#FLAGS="--host=arm-androideabi-linux --enable-static --enable-shared --prefix=$HOME --enable-armv5e "
CROSS_COMPILE=$TOOLCHAIN/bin/arm-linux-androideabi-
export CPPFLAGS="$CFLAGS"
export CFLAGS="$CFLAGS"
export CXXFLAGS="$CFLAGS"
export CXX="${CROSS_COMPILE}g++ --sysroot=${PLATFORM}"
export LDFLAGS="$LDFLAGS"
export CC="${CROSS_COMPILE}gcc --sysroot=${PLATFORM}"
export NM="${CROSS_COMPILE}nm"
export STRIP="${CROSS_COMPILE}strip"
export RANLIB="${CROSS_COMPILE}ranlib"
export AR="${CROSS_COMPILE}ar"
./configure --prefix="/home/mcy/faac-1.28/install/" --without-mp4v2 --enable-static --disable-shared  --host=arm-linux
}
build_faac  

执行脚本，生成libaac.a静态库。若想要生成动态库，去掉编译选项--disable-shared即可。
