Problem with a makefile

[Tweety]

I tried to run a project with 2 source files and a header file and there was some kind of problem with the linking (as the modules compile successfully separately). Moreover, the files were from a Qt tutorial so they should work...
So I thought I'd create a makefile and then use make (btw i use mingw make). So eventually I created the makefile with qmake and then when I typed make in the command line I got this error message: "mingw32-make:*** No targets specified and no makefile found.Stop.". Then I tried make -f makefile and it said: "makefile:65:*** multiple target patterns. Stop.". And from this point on I didn't know what else to do.
Other technical details: I use Windows XP, Qt 4.1, MinGW 5.0.2

I will attach the makefile and maybe someone will spot the problem.
Thanks in advance.

Your Makefile doesn't contain any rules that generate code --- your .pro file must be wrong. Could you post it?

[Tweety]

Yep sure. Here it is:

[jacek]

Add "TEMPLATE = app", run "qmake QTapp.pro" and then make.

[Tweety]

I get the same error message....
Could it be a problem with MinGW?

What files do you have in your project directory?

[Tweety]

The files in the project directory are: lcdrange.h, lcdrange.cpp and main.cpp.

I eventually got to a more radical solution: I just deleted the lines in the makefile from line 65 to the end and it worked . But it's still kind of a mystery why it wouldn't work in the first place.

qmake generates paths that contain colons; Since microsoft operating systems have paths with the syntax drive:path the colon is interpreted by make as a separator instead of being part of the path.

The problem is either in your version of make(because it doesn't interpret that colon as expected) or in qmake because it generates a bad Makefile.

It's strange that you are using mingw which is said to be supported by open source Qt.

Maybe you should try with make from MSYS but still I don't understand why it doesn't work with mingw32-make.

Where is the .pro file?

There are some problems with MSYS. Anyway, Qt4 should work without any problems with MinGW and cmd.exe.

Where is the .pro file?

The .pro file is in the exact same directory.

[jacek]

The .pro file is in the exact same directory.

This is really strange. How do you invoke qmake? What is the current directory?

[Tweety]

I invoke qmake with "qmake -o Makefile QTapp.pro" in the directory where the .pro file is located.

Did you try deleting Makefile before running qmake?

[Tweety]

I tried not to use the make that came with mingw and instead I used the make in CodeBlocks and it works. So I guess something was wrong with mingw make...
Anyway, at least it works now, so I can start "playing" with Qt

If you don't have two installations of MinGW then Code::Blocks is using the same "make" executable you invoked from the command line.

Did you try deleting Makefile before running qmake?

Most probably that was the issue. If I do qmake -spec linux-g++ and then qmake -spec linux-icc I get the gcc Makefile again , I have to manually delete it to get the one for icc.
