Error while building project Text_Editor (target: Desktop)
When executing build step 'Make'

I have no clue on that. I just installed it, created a new project and got that error instantly.

Answer 1

Try to change your build directory from C:/Qt/2010.05/Text_Editor-build-desktop to C:/Qt/2010.05/Text_Editor.

To do this just open your project in Qt creator, left click on Project on the left pane, then open build settings tab and edit Build directory input field.

Answer 2

Run Qt Creator with "Run as Administrator".

I had pretty much the same problem just now. Without getting into "why" - I unticked "Shadow build" from project options and my build was succesful. Funny part is - "Shadow build" worked yesterday, and nothing really changed that much in between.

Answer 4

For reason or another it is not able to find your main.cpp (g++: ..\Text_Editor\main.cpp: No such file or directory). Basically that path should be ok if you have shadow build toggled on.

Location where the main.cpp is tried to find is:

C:/Qt/2010.05/Text_Editor/main.cpp

Double check that this is proper location (notice also case sensitivity to be sure)

you can try toggling off the shadow build from project -> check off shadow build. And also you should check that Text_Editor.pro contains properly the main.cpp.

Edit: It might be also wise to create that project outside the Qt binary folder, to some other more logical folder.

Answer 5

What worked for me was the way I added headers in a .pri.

This works...

HEADERS += ../serialportwidget.h
HEADERS += ../serialportworker.h
SOURCES += ../serialportwidget.cpp
SOURCES += ../serialportworker.cpp

or this

HEADERS += ../serialportwidget.h \
../serialportworker.h
SOURCES += ../serialportwidget.cpp \
../serialportworker.cpp

This doesn't...

HEADERS += ../serialportwidget.h \ ../serialportworker.h
SOURCES += ../serialportwidget.cpp \ ../serialportworker.cpp
