porting code from 4.8 to 5.1: No rule to make ui target

**MartinCook** · 8th December 2013, 01:12

On Windows 7.

Just installed Qt 5.1.1 and started recompiling my code.

I don't use QtDesigner. I use my own ui.h file.

Getting the following error:

:-1: error: No rule to make target 'bits.ui', needed by 'ui_bits.h'. Stop.

The ui header I use is named bits.ui.h, not ui_bits.h, which is what QtDesigner wants to use.
This all worked fine with Qt 4.8.

Here is my project file.

Qt Code:

Switch view

QT       += core gui
 
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
 
TARGET = bits
TEMPLATE = app
 
SOURCES += main.cpp \
    hexedit.cpp \
    bits.cpp \
    bitfield.cpp \
    BitButton.cpp \
    shiftop.cpp \
    formatgroup.cpp
 
HEADERS  += \
    controlgroup.h \
    bits.ui.h \
    bits.h \
    bitfield.h \
    BitButton.h \
    hexedit.h \
    shiftop.h \
    formatgroup.h
 
FORMS    += \
    bits.ui

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = bits
TEMPLATE = app

SOURCES += main.cpp \
    hexedit.cpp \
    bits.cpp \
    bitfield.cpp \
    BitButton.cpp \
    shiftop.cpp \
    formatgroup.cpp

HEADERS  += \
    controlgroup.h \
    bits.ui.h \
    bits.h \
    bitfield.h \
    BitButton.h \
    hexedit.h \
    shiftop.h \
    formatgroup.h

FORMS    += \
    bits.ui

To copy to clipboard, switch view to plain text mode

I tried removing the FORMS += bits.ui from the project, but the error persists.

I'm certain it's an error on my part, but googling this error has been no help.

OK, I found the answer at this link.

The important part of the thread is this:

Rerun qmake (Build->Run qmake), or, if that fails, clean the output directory and rebuild your project.
Also make sure you have a QT += widgets in your .pro file. Qt5 moved widgets to separate library.

I had done all the other stuff, so it was Build->Run qmake that did it for me.
