Hi, I'm running Archlinux 32bit on my laptop and so far I've gotten the IDE to compile without any major issues. When I started to compile libkovan I get the following error:

[ 0%] Building CXX object CMakeFiles/kovan.dir/src/ardrone_video_p.cpp.o

I believe the error has something to do with libav. The version I'm using is 9.11 (the latest one found here: https://libav.org/download.html). If you need any more information I'll be glad to provide it for you.

Fixed it:
changed
File: ardrone_video_p.cpp
m_codecCtx = avcodec_alloc_context(); to m_codecCtx = avcodec_alloc_context3(NULL); Line: 201
m_codecCtx->error_recognition = FF_ER_CAREFUL; to mcodecCtx->err_recognition = AV_EF_CRCCHECK; Line: 205

Other minor errors that I came across compiling cs2:
include/port_configuration.hpp
Changed
#include QMetatype to #include QMetaType

I'm not sure how to link cs2 and the KISS IDE so any help with that would be great. Also I would like to change the install directory because I don't like keeping it in my Downloads folder.

For whatever reason this post isn't showing up in the forum.
