You are attempting to install khulnasoft-lab as a non-root user, but you plan
to install it in system paths.
Please set an installation prefix, like this:
$PROGRAM ${@} --install-prefix /tmp
or, run the installer as root:
sudo $PROGRAM ${@}
We suggest to install it as root, or certain data collectors will
not be able to work. Khulnasoft-lab drops root privileges when running.
So, if you plan to keep it, install it as root to get the full
functionality.

You are about to install khulnasoft-lab as a non-root user.
Khulnasoft-lab will work, but a few data collection modules that
require root access will fail.
If you are installing khulnasoft-lab permanently on your system, run
the installer like this:
${TPUT_YELLOW}${TPUT_BOLD}sudo $PROGRAM ${@}${TPUT_RESET}

where options include:
--install-prefix <path> Install khulnasoft-lab in <path>. Ex. --install-prefix /opt will put khulnasoft-lab in /opt/khulnasoft-lab.
--dont-start-it Do not (re)start khulnasoft-lab after installation.
--dont-wait Run installation in non-interactive mode.
--stable-channel Use packages from GitHub release pages instead of nightly updates.
This results in less frequent updates.

--enable-plugin-systemd-journal Enable the the systemd journal plugin. Default: enable it when libsystemd is available.
--disable-plugin-systemd-journal Explicitly disable the systemd journal plugin.
--enable-exporting-kinesis Enable AWS Kinesis exporting connector. Default: enable it when libaws_cpp_sdk_kinesis
and its dependencies are available.
--disable-exporting-kinesis Explicitly disable AWS Kinesis exporting connector.
--enable-exporting-prometheus-remote-write Enable Prometheus remote write exporting connector. Default: enable it
when libprotobuf and libsnappy are available.
--disable-exporting-prometheus-remote-write Explicitly disable Prometheus remote write exporting connector.
--enable-exporting-mongodb Enable MongoDB exporting connector. Default: enable it when libmongoc is available.
--disable-exporting-mongodb Explicitly disable MongoDB exporting connector.
--enable-exporting-pubsub Enable Google Cloud PubSub exporting connector. Default: enable it when
libgoogle_cloud_cpp_pubsub_protos and its dependencies are available.
--disable-exporting-pubsub Explicitly disable Google Cloud PubSub exporting connector.
--enable-lto Enable link-time optimization. Default: disabled.
--disable-lto Explicitly disable link-time optimization.
--enable-ml Enable anomaly detection with machine learning. Default: autodetect.
--disable-ml Explicitly disable anomaly detection with machine learning.
--disable-x86-sse Disable SSE instructions & optimizations. Default: enabled.
--use-system-protobuf Use a system copy of libprotobuf instead of bundled copy. Default: bundled.
--zlib-is-really-here
--libs-are-really-here If you see errors about missing zlib or libuuid but you know it is available, you might
have a broken pkg-config. Use this option to proceed without checking pkg-config.
--disable-telemetry Opt-out from our anonymous telemetry program. (DISABLE_TELEMETRY=1)
--skip-available-ram-check Skip checking the amount of RAM the system has and pretend it has enough to build safely.
--disable-logsmanagement Disable the logs management plugin. Default: autodetect.
--enable-logsmanagement-tests Enable the logs management tests. Default: disabled.
Khulnasoft-lab will by default be compiled with gcc optimization -O2
If you need to pass different CFLAGS, use something like this:
CFLAGS="<gcc options>" ${PROGRAM} [options]
If you also need to provide different LDFLAGS, use something like this:
LDFLAGS="<extra ldflag options>" ${PROGRAM} [options]
or use the following if both LDFLAGS and CFLAGS need to be overridden:
CFLAGS="<gcc options>" LDFLAGS="<extra ld options>" ${PROGRAM} [options]
For the installer to complete successfully, you will need these packages installed:
gcc
make
autoconf
automake
pkg-config
zlib1g-dev (or zlib-devel)
uuid-dev (or libuuid-devel)
For the plugins, you will at least need:
curl
bash (v4+)
python (v2 or v3)
node.js
