--- Comment #1 from Fabrice Fontaine <fontaine.fabrice@gmail.com> ---
Could you provide more information about the build failure:
 - at least the config.log that is generated by configure
 - the defconfig that fails to build
 - the version of buildroot that you're using (lldpd has been bumped to 1.0.5
since April so I assume that you're using the 2020.02.x branch?)

It should be noted that there isn't any build failure with lldpd 1.0.4 and
above in our autobuilders: http://autobuild.buildroot.org/?reason=lldpd%.

(In reply to Fabrice Fontaine from comment #1)
1. Please refer to attachment config.log
2. Please refer to attachment defconfig
3. buildroot version 2020.02.6

When I do configure and make in lldp directory, it can pass, but seems libevent
is shipped which is difference with doing build from root directory, please
refer to attachment (lldp directory configure and make log)

checking for libevent... no
configure: using shipped libevent
=== configuring in libevent
(/repo/erhu/buildroot/output/build/lldpd-1.0.4/libevent)

--- Comment #6 from Thomas De Schampheleire <patrickdepinguin@gmail.com> ---
Problem is caused by internal changes in our tree (only the 'core' component of
libevent being build, thus no libevent.so).

Closing as invalid.
