Thanks..

For future reference, can we get the full steps for compiling.. Encountered errors while attempting to build it (tried centos, fedora), I already installed the prerequisites you mentioned.

hi,
nevermind about recompiling.... i've made every error (except the memory allocations) to warning with the below change:
https://github.com/rare-freertr/freeRtr/commit/a59b34ecaa14ad276267cb0f5542678c219b0d71
as far as i know the fedora is daily rebuilds itself automatically, so just wait a day and upgrade afterwards...
br,
