Endless loop of qmake.exe

koahnig

welcome to devnet

How do you start qmake?

Benjamin05

I work with QtCreator and the problem occurs whenever I build or clean a project. I can even not build the Qt examples anymore.

When I run qmake in QtCreator I do not get an error message.

Please check out also the "forum help for setting code tags":http://qt-project.org/wiki/ForumHelp#e3f82045ad0f480d3fb9e0ac2d58fb01 Code tags help to make code as well as error output a bit more readable.

When you run qmake in Qt creator you do not get an error message. When do you get the error message then?

Benjamin05

I do not get an error message, but when I run a project it never finishes with step one of the build. Instead it puts as compile output the following lines again and agian.
@C:/Qt/Qt5.1.0/5.1.0/mingw48_32/bin/qmake.exe -spec win32-g++ CONFIG+=debug CONFIG+=declarative_debug CONFIG+=qml_debug -o Makefile C:/Backups/Qt_waypoits_listed/naplps_project/arinc2network/src/arinc2network.pro@
Also if I clean the project the process never ends with the same lines.

If you go in creator to "Projects" (left sidebar) you can see the "Build Settings". You should have "Build Steps" and "Clean Steps".

For "Build Steps" there should be two entries:
qmake: ...something...
Make: ...something...
What do the entries say?

For the "Clean Step" there should be one entry.
Make: ...something...
What does it say?

You can also post in addition a screenshot of that page. However, uploading of pictures is not possible here. The best thing is to use Dropbox and share a picture whose link you can post here in this box (left of link sign).

Benjamin05

I cannot access dropbox from here, therefore the entries in this way:

Build steps
qmake: qmake.exe arinc2network.pro -r -spec win32-g++ "CONFIG+=debug" "CONFIG+=declarative_debug" "CONFIG+=qml_debug"

koahnig

Those entries look fine to me.

Try to start the makefile from cmd.exe directly.
Open the command prompt.
@
set path=
cd C:\QT_layout_fixed\naplps_project\arinc2network\build-arinc2network-Desktop_Qt_5_1_0_MinGW_32bit-Debug
C:/Qt/Qt5.1.0/Tools/mingw48_32/bin/mingw32-make.exe
@
The first statement clears your path to avoid side effects.
Certainly you can go step by step to the shadow folder "build-arinc2network-Desktop_Qt_5_1_0_MinGW_32bit-Debug".
You should find the "Makefile" there. This would be started with "mingw32-make".

Benjamin05

Hey,
thanks for your help.

I confused two of my backups in my last post. Both directories are of course:
C:\Backups\Qt_waypoits_listed...

Now I set the path to the debug folder and ran make.exe asyou discribed.
As output I get the same problem as when building or cleaning a project:

@C:/Qt/Qt5.1.0/5.1.0/mingw48_32/bin/qmake.exe -spec win32-g++ CONFIG+=debug CONFIG+=declarative_debug CONFIG+=qml_debug -o Makefile ../src/arinc2network.pro@
This is posted on and on.

In the folder are a Makefile, a Makefile.Debug and a Makefile.Release.
The text in the Makefile is the following:

further done in the file you should something like
@
clean: compiler_clean
-$(DEL_FILE) ... long list of objects ...
@

in the compile section
@
bliblo.o: ../../ ..... blobli.cpp ../../ .... blobli.h
list of other headers
$(CXX) -c $(CXXFLAGS) $(INCPATH) -o blobli.o blobli.cpp
@

Note: I have shortened the path considerably. The important part after each object is the $(CXX) plus subsequent stuff.

Benjamin05

I have following parts in the Makefile.Debug:
@clean: compiler_clean
-$(DEL_FILE) debug/main.o debug/socketconfig.o debug/advtcpsocket.o debug/aimcard.o debug/condorcard.o debug/arincChannel.o debug/advtcpserver.o debug/moc_advtcpsocket.o debug/moc_aimcard.o debug/moc_condorcard.o debug/moc_arincChannel.o debug/moc_advtcpserver.o

@

Also I have the $(CXX) plus subsequent stuff in the compile section for every header/source pair I add in my .pro file I removed the other headers for the post.
I do not have a moc_socketconfig.o entry, but I do not know, if this is a problem

Frankly, I am running out of ideas by now.

When you are starting mingw32-make from cmd.exe with parameter "--version" what does it tell you?

Benjamin05

Following text is displayed when runing with "--version". Nothing else is executed.

I have no clue, what has happend to my QtCreator. The error occured after I was running qmake. Afterwards none of my projects, also the backups cannot be build or cleaned anymore, thoug they still work on a other computer. After running qmake and building successfully on a other computer, I can even run on this computer, as long as the 'Configuration unchanged, skipping qmake step.'
Unfortunatly the application does not changeif I then make any changes in the code. And after I run qmake, which is successful, I cannot build any more with the old problem.
Reinstalling Qt did not solve the problem either.

koahnig

Well, you wrote that starting mingw32-make on the command show the same problem. This is a bit strange. This means that the makefile is wrong. Which is generated by qmake.

Since you can produce a makefile on the still working pc, you can compare the makefiles.
If you have the setup (versions and folders) you can take over the qmake from pc to the other. Make a copy of qmake before you copy the version over it.

Benjamin05

I have compared the makefiles using kdiff and found some differences:

Also are there a lot of backslash and slash differences!

Furthermore I am currently able to use one of my projects on the defect computer after building it successfully on another one. I can build clean and run qmake without problems, though I have no clue, why this project works now.
Unfortunatly all other projects do either not run at all, or do not runafter I made qmake on the defect computer.

koahnig

backslashes could be the problem.
Checkout on the "defect" setup computer your .pro files.
DO NOT use backslashes in Qt related for folders. They have a special meaning and mark that the next line is a continuation line.
A .pro file should have statements like:
@
HEADERS += ./head.h
./head2.h
c:/AnotherHeader/header3.h
c:/Blo/bli.h
@

As you see at the end of lines there is a backslash when another line is following.

Benjamin05

Yes, but I have used the same .pro file on both computers, without changing it. And if I open the .pro file on the defect computer, everything looks fine:

Did you copy the qmake from one machine to the other?
Do not forget the safety copy!

Are both OS identical?
Any OS language settings? Which are different?

I have copied the whole project from one pc to the other. I could not build it, then I ran qmake and could again not build it. The I compared the new makefile with the backup.Unfortunatly are the backslashes created by the computer, that is working fine. The "correct" slashes are created by the computer that is getting the endless loop.

The problem is, that I cannot even reproduce the behaviour. I have some older makefiles from the "working" computer, which have no false baskslashes. This morning I tried and it made backslashes in the path. Still building the project worked fine. Sometimes I can build the project on the defect PC (when creating the makefile is skipped - the configuration has not changed) when I copy it from the working pc, sometimes the endless build occurs and sometimes I get Makefile Error 2 message. And the one file I copied can be build even after I run qmake on the defect PC.

Both OS are a french windows xp version. Qt is both times english and version 5.1.0
