111 you have a broken pkg-config.

349 You many need to check these:
351 1. The package uuid-dev (or libuuid-devel) has to be installed.
353 If your system cannot find libuuid, although it is installed
354 run me with the option: --libs-are-really-here

358 If your system cannot find zlib, although it is installed

361 3. You need basic build tools installed, like:
363 gcc make autoconf automake pkg-config

1143 Update check on the dashboard, will not work.

1161 apps.plugin needs privileges
1163 Since you have installed netdata as a normal user, to have apps.plugin collect
1164 all the needed data, you have to give it the access rights it needs, by running
1165 either of the following sets of commands:
1167 To run apps.plugin with escalated capabilities:
1169 sudo chown root:${NETDATA_USER} "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1170 sudo chmod 0750 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1171 sudo setcap cap_dac_read_search,cap_sys_ptrace+ep "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1173 or, to run apps.plugin as root:
1175 sudo chown root "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1176 sudo chmod 4755 "${NETDATA_PREFIX}/usr/libexec/netdata/plugins.d/apps.plugin"
1178 apps.plugin is performing a hard-coded function of data collection for all
1179 running processes. It cannot be instructed from the netdata daemon to perform
1180 any task, so it is pretty safe to do this.
