----------------------------------------
Summary: Update BUILDING.txt to include the correct steps to
install zstd library
Key: HADOOP-14482
URL: https://issues.apache.org/jira/browse/HADOOP-14482
Project: Hadoop Common
Issue Type: Improvement
Components: io
Affects Versions: 3.0.0-alpha2
Reporter: Wei-Chiu Chuang
Priority: Minor
The current BUILDING.txt includes the following steps for installing zstd
library:
$ sudo apt-get install zstd
This is incorrect. On my Ubuntu machine, zstd is not a library
{quote}
apt-cache search zstd
libzstd-dev - fast lossless compression algorithm -- development files
libzstd0 - fast lossless compression algorithm
zstd - fast lossless compression algorithm -- CLI tool
{quote}
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.

* 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.
