linux中flac安装

在跑mini_librispeech的时候，下载好数据会提示Please install ‘flac’ on ALL worker nodes!
这是因为数据集是flac的压缩格式，而Linux系统没有安装解码的软件，所以我们需要安装flac。

第一步 下载

wget  https://downloads.xiph.org/releases/flac/flac-1.3.3.tar.xz
wget http://www.linuxfromscratch.org/patches/blfs/svn/flac-1.3.3-security_fixes-1.patch

第二步 解压

下载下来的文件是 .tar.xz 格式的压缩包,进入到下载目录

$ xz -d flac-1.3.3.tar.xz 
$ tar -xvf flac-1.3.3.tar

第三步 安装（需要root权限）

Install FLAC by running the following commands:

cd flac-1.3.3

patch -Np1 -i ../flac-1.3.3-security_fixes-1.patch      &&
./configure --prefix=/usr                                \
            --disable-thorough-tests                     \
            --docdir=/usr/share/doc/flac-1.3.3          &&
make

To test the results, issue: make check. Note that if you passed the --enable-exhaustive-tests and --enable-valgrind-testing parameters to configure and then run the test suite, it will take a very long time (up to 300 SBUs) and use about 375 MB of disk space.

Now, as the root user:

make install

参考中提到下文，不过我没有用到。

第四步 source 把你安装的路径中有个 bin 文件夹，放到环境变量中( .bash 或者 .bash_profile)。

source .bash 或者 source .bash_profile

第四步 测试

$ flac
