Pass a method to QtConcurrent::map

nulluse

See my last update - adding QT += concurrent does not change anything as the project thinks configuration is not changing.

Sometimes the IDE is not as smart and it doesn't understand the .pro has changed. Run qmake explicitly (somewhere in the build menu) and do a rebuild after that.

Forcing rebuild does not change anything. The pro file looks like this now:

QT += core gui concurrent
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = MandelbrotQt
TEMPLATE = app
SOURCES += main.cpp\
        newform.cpp \
    helpers/fileHelper.cpp \
    mandelbrot/mandelbrot.cpp
HEADERS  += newform.h \
    helpers/fileHelper.h \
    mandelbrot/mandelbrot.h \
    ui_newForm.h
FORMS    += newform.ui
LIBS += -lQt5Concurrent
CONFIG += c++11

The linker is still complaining.

It looks okay to me, with the only exception of this line: LIBS += -lQt5Concurrent. You shouldn't need to pass that to the linker, adding the QT += concurrent is enough (qmake will generate the appropriate include files and linker switches).

Running qmake fixed it!
