Hi, thanks for your reply.
I've written .pro
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
CONFIG += no_keywords
DEFINES += GETTEXT_PACKAGE
QMAKE_CXXFLAGS += -fpermissive
PKGCONFIG += libbrasero-burn3 libbrasero-media3 libnotify
LIBS += -lbrasero-burn3 -lbrasero-media3 -lnotify
CONFIG += link_pkgconfig
yesterday, i build my code in another linux OS, and no error. I think this problem in connection with LinuxMint 18.
Thanks again.
