Odd compilation bugs

kamill

Hi,
I've got some strange problems with one of my Qt projects (it's called gen1). The problem is that Qt Creator doesn't compile it, unless I manually delete the build folder of this project. If I don't, I get this error:
@[debug\gen1.exe] Error 1

mingw32-make[1]: *** [debug\gen1.exe] Error 1
mingw32-make: *** [debug] Error 2@

Moreover, if there's a bug in the code, instead of showing me where the problem is, I get this error:
@[debug/mainwindow.o] Error 1

mingw32-make[1]: *** [debug/mainwindow.o] Error 1
mingw32-make: *** [debug] Error 2@

The problem exists only in this single project. I've tried to make a new project and after copying the code and I've tried to reinstall Qt but it didn't solve my problem.

Here's some info:
Qt Creator 2.3.0
Qt 4.7.4
Windows 7 64-bit

Here's the content of gen1.pro:
@QT += core gui

TARGET = gen1
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui@

Any help is greatly appreciated.

What is the actual error? That usually happens before the text you posted.

The problem is that actually there are no errors:

There is a known issue with using directories with spaces embedded in them. The problem arises because of the directory "D:/stud/modelowanie i symulacja". If you move your project to a different (non-spaced) directory, it should work properly.

Thank you for the advice, but unfortunately it didn't work. I've created a new project in d:/gen1/ and I still get the same errors.

I forgot to add that on Linux the compilation works fine.
