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

I have no idea about this. I just installed it, created a new project and instantly got this error.

Answer 1

I had almost the same problem just now. Without going into the “why” - I dismissed the “Shadow build” from the project options, and my build was successful. The funny part is the Shadow Build worked yesterday, and nothing has changed so much between them.

Answer 2

For one reason or another, it cannot find your main.cpp (g ++: .. \ Text_Editor \ main.cpp: there is no such file or directory). Basically, this path should be ok if you have shadow assembly enabled.

The place where trying to find main.cpp is this:

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

Make sure this is the correct location (also pay attention to case sensitivity)

you can try to disable the shadow assembly from the project -> close the shadow assembly. And also you should check that Text_Editor.pro contains correctly main.cpp.

Edit: It might be advisable to create this project outside of the Qt binary folder, in another more logical folder.

Answer 3

Try changing the assembly directory from C: /Qt/2010.05/Text_Editor-build-desktop to C: /Qt/2010.05/Text_Editor .

To do this, simply open your project in the Qt creator, left-click on the Project in the left pane, then open the build options tab and edit the Build directory .

Answer 4

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

It works...

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

or

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

Is not...

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

Answer 5
