Title: librepilot-gcs error on Ubuntu 16.04. QtQuick version 2.6 not installed
Post by: ufechner on January 25, 2017, 12:06:30 pm

Hello,
I compiled librepilot-gcs from source, and get the following error when launching it:

/home/ufechner/librepilot/build/librepilot-gcs_release/lib/librepilot-gcs/plugins/LibrePilot/libPfdQml.so: Cannot load library /home/ufechner/librepilot/build/librepilot-gcs_release/lib/librepilot-gcs/plugins/LibrePilot/libPfdQml.so: (/usr/lib/liblapack.so.3: undefined symbol: gotoblas)

Any idea?

I already tried to use a different version of liblapack.so.3 by running:
sudo update-alternatives --config libblas.so.3

But this did not help.

I was able to solve this problem with the command:
sudo update-alternatives --config liblapack.so.3

But now there is a second problem, only when I try to show the "About"
dialog.

I get the message:
qrc:/core/qml/AboutDialog.qml:24:1: module "QtQuick" version 2.6 is not installed

Any idea how to install it?

Uwe
