还是先说下环境，系统是CentOS 7.9（怕玩坏了，用的docker，官方镜像centos:centos7.9.2009），配合ARM官方的linux工具链gcc-arm-8.3-2019.03-x86_64-aarch64_be-linux-gnu.tar.xz（这里： https://developer.arm.com/downloads/-/gnu-a），解压到了 /usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu，使用环境变量：
export AR="/usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-ar" export AS="/usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-as" export CC="/usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc" export CXX="/usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-g++" export RANLIB="/usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-ranlib" export STRIP="/usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin/aarch64-linux-gnu-strip" export PATH="/usr/local/ARM-toolchain/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu/bin:$PATH"
来指定交叉编译工具链，依赖的libsamplerate库版本是：0.2.2，报错信息如下：
