Hi,
I was trying to build "Next" revision, on Linux x64 LTS 14.05. Everything went fine, except when I try to launch binary I get few errors:

./build/librepilot-gcs_release/bin/librepilot-gcsCommand line ("./build/librepilot-gcs_release/bin/librepilot-gcs")

I've checked up, qt56multimedia is present and up to date. Any ideas?

regards,
Gedas

Hi
Without looking very closely on this it looks like a version mismatch of some Qt libs.
Im afraid its hard for me to give any more help right now. I will try to build it on my Linux VM and see if I can repro it.

If you want to use the Qt5.6 from host you should remove or move the tools/qt-xxx to another dir, same for osg/osgearth

Looks how Travis do the build:
https://travis-ci.org/librepilot/LibrePilot

Code: [Select]

sudo add-apt-repository ppa:librepilot/tools -y
sudo apt-get update -q
sudo apt-get install -y libc6-i386 libudev-dev libusb-1.0-0-dev libsdl1.2-dev python libopenscenegraph-dev libosgearth-dev qt56-meta-minimal qt56svg qt56script qt56serialport qt56multimedia qt56translations qt56tools
make arm_sdk_install
make config_new CCACHE=ccache GCS_EXTRA_CONF='osg osgearth'

make all_flight
make opfw_resource
make gcs

Thanks for the answers! Actually those commands has helped. It seems something was missed by initial apt-get sequence which I've took from wiki.
