${ME} <installer options>
Valid <installer options> are:
--install /PATH/TO/INSTALL
If your give: --install /opt
netdata will be installed in /opt/netdata
--dont-start-it
Do not (re)start netdata.
Just install it.
--dont-wait
Do not wait for the user to press ENTER.
Start immediately building it.
--zlib-is-really-here
If you get errors about missing zlib,
but you know it is available,
you have a broken pkg-config.
Use this option to allow it continue
without checking pkg-config.
Netdata will by default be compiled with gcc optimization -O3
If you need to pass different CFLAGS, use something like this:
CFLAGS="<gcc options>" $ME <installer options>
For the installer to complete successfully, you will need
these packages installed:
gcc make autoconf automake pkg-config zlib1g-dev
For the plugins, you will at least need:
curl node

Welcome to netdata!
Nice to see you are giving it a try!
You are about to build and install netdata to your system.
It will be installed at these locations:
- the daemon at ${NETDATA_PREFIX}/usr/sbin/netdata
- config files at ${NETDATA_PREFIX}/etc/netdata
- web files at ${NETDATA_PREFIX}/usr/share/netdata
- plugins at ${NETDATA_PREFIX}/usr/libexec/netdata
- cache files at ${NETDATA_PREFIX}/var/cache/netdata
- log files at ${NETDATA_PREFIX}/var/log/netdata
This installer allows you to change the installation path.
Press Control-C and run the same command with --help for help.

Sorry, you do not seem to have autotools 2.60 or later, which is
required to build from the git sources of netdata.
You can either install a suitable version of autotools and automake
or download a netdata package which does not have these dependencies.
Source packages where autotools have already been run are available
here:
https://firehol.org/download/netdata/
The unsigned/master folder tracks the head of the git tree and released
packages are also available.

Sorry! NetData failed to build...
You many need to check these:
1. The package zlib1g-dev has to be installed.
2. You need basic build tools installed, like:
gcc make autoconf automake pkg-config
Autoconf version 2.60 or higher is required
3. If your system cannot find ZLIB, although it is installed
run me with the option: --zlib-is-really-here
If you still cannot get it to build, ask for help at github:
https://github.com/firehol/netdata/issues
