The current BUILDING.txt includes the following steps for installing zstd library:
$ sudo apt-get install zstd
This is incorrect. On my Ubuntu 16 machine, zstd is not a library
apt-cache search zstd
libzstd-dev - fast lossless compression algorithm – development files
libzstd0 - fast lossless compression algorithm
zstd - fast lossless compression algorithm – CLI tool
On a Ubuntu 14 machine, I couldn't even find anything related to zstd.
In fact, to build Hadoop with ZStandard library, I have to install libzstd-dev.
I will also need to install the runtime to use it. libzstd0 is the older version. libzstd1 is for zstd 1.x. It's not clear to me if libzstd0 is compatible. CentOS does have libzstd1 though.
Perhaps we can provide instruction to compile/install libzstd from source code.
- Use -Dzstd.prefix to specify a nonstandard location for the libzstd
header files and library files. You do not need this option if you have
installed zstandard using a package manager.
- Use -Dzstd.lib to specify a nonstandard location for the libzstd library
files. Similarly to zstd.prefix, you do not need this option if you have
installed using a package manager.
At least for CentOS, the library installed by rpm was not located and I had to specify -Dzstd.prefix to get it installed.
