Hi,
This error will come due to library file linking preference in Makefile.
Python library should be linked at the end so you have to change the Makefile as below.
By default, python library "-lpython3.4m" is linked with "LFLAGS" in Makefile.
Solution:-
Remove the "-lpython3.4m" from LFLAGS in Makefile and add it at the end in "LIBS" variable after linking of Qt libraries as below.
LIBS = $(SUBLIBS) -lQt5WebKitWidgets -L/usr/lib/i386-linux-gnu -lQt5Quick -lQt5OpenGL -lQt5PrintSupport -lQt5WebKit -lQt5Qml -lQt5Location -lQt5Widgets -lQt5Network -lQt5Positioning -lQt5Sensors -lQt5Gui -lQt5Core -lGL -lpthread -lpython3.4m
Hope, it will solve your issue.
Let us know if you still face the same issue.
Thanks,
Neel Patel
