makefile is looping for generating makefile

Hi,

I have some problems generating the Makefile from demo.pro. Everytime I change someting in my project the makefile is looping to generate the Makefile.

I am using qt 3.3.4 on redhat linux 8.0

qmake -o Makefile demo.pro
qmake -o Makefile demo.pro
qmake -o Makefile demo.pro
qmake -o Makefile demo.pro

this will loop forever. I see in the makefile that by rule all

all: Makefile $(TARGET).

How to solve this problem

Thanks

Johan

Can you give us the demo.pro code ?

It should help!

Here is my demo.pro

TEMPLATE = app
LANGUAGE = C++

CONFIG += qt warn_on release

LIBS += -L/opt/omniORB/lib -L/home/jdb/ticketing/Components/lib -lomniORB4 -lsalescorbaclient -lomnithread -lpthread -lbusinessobjects -ldomainobjects -lserializerobjects -lnsutil -ltinyxml

DEFINES += TIXML_USE_STL

INCLUDEPATH += /opt/omniORB/include /home/jdb/ticketing/Components/include

HEADERS += kaart.h

SOURCES += main.cpp \
kaart.cpp

FORMS = mainform.ui

unix {
UI_DIR = .ui
MOC_DIR = .moc
OBJECTS_DIR = .obj
}

regards

Johan

Strange,
I don't see anything wrong in this file...
Maybe add a line like this:
TARGET = demo

You know, if you're in the directory that contains demo.pro, you just have to type 'qmake'

Hi,

typing qmake fixes the problem. Thanks

Maybe make can't modify Makefile? Also check the modification time of the .pro file.

No, I have write permissions on all files. Every time I change something the makefile is trying to generate the new makefile because of the rule :

all : Makefile $(TARGET)

I do not understand why this rule is created with Makefile as one of the targets. I think this is a bug in qmake. Anyone know of this bug, or feature

You need this rule, because you need a new Makefile every time you change your .pro file.

On my system qmake adds the same rule and everything works OK. There must be something wrong with your make or file modification times.

Yes you are right. Something strange is going on. The file changed has the same date/time as my system date/time but the makefile generated by qmake is different (about 4 minutes before current time). Seems that qmake writes a Makefile with the wrong date/time.

If the *.pro file has been modified, the Makefile indeed attempts to rebuild itself. That's by design and not a bug.

Now the question is why make is looping endlessly? Have you checked the modification time of the *.pro file?

Which Linux distribution is this? Red Hat 8.0?

Yes I use redhat 8.0 and qt 3.3.4. The modification time of the generated Makefile is about 4 minutes before the system date/time. The changed sources have the same date/time as the system time. I am wondering why the Makefile has an old date/time stamp.
