QT 5.7 error compile on Wandboard

**aletes** · 27th October 2016, 23:33

I am configuring my Ubuntu system to develop on arm platform with a wandboard card.
I followed these guides:
http://wiki.wandboard.org/index.php/...o_on_Wandboard
http://wiki.wandboard.org/index.php/..._in_QT_Creator

and the environment properly installed.
I installed QT: Based on Qt 5.7.0 (GCC 4.9.1 20140922 (Red Hat 4.9.1-10), 64-bit)
I'm trying to compile a simple application but using the standard kit (Desktop) the application is compiled; if I try to use the configured kit for wandboard card, created as indicated by the wiki the build fails with these three errors:
: -1: Error: can not find -lQt5Widgets
: -1: Error: can not find -lQt5Gui
: -1: Error: can not find -lQt5Core

What is missing in configuration?

You probably need to add a "-L<path to Qt libs>" directive on your link line (where "<path to Qt libs>" is wherever the Qt libraries live for your kit). If you are using a .pro file, then it needs to be added to the LIBS line.

Are those the actual names of the Qt libraries (.a or .so files)? With the correct case? Do you see those libraries in that location? Are the libraries the correct "bitness" (32 vs. 64-bit)?
