Getting Started

[Hockey]

I've poke around the forums and Googled on getting started with Qt. When I initially downloaded I was under the impression it also came with an IDE. However now it appears it's everything BUT the IDE. This is OK because I am already familiar with Visual Studio although I no longer develop using it, instead I prefer to use UltraEdit for all my web development needs.

I am interested in picking up some C++ again but wanted cross platform and decided to try Qt out.

Can someone point me in the direction in just getting started setting up the proper tool chain required to compile a basic Widget window?

It sounds like I use qmake to generate a project file and that project file will invoke all the proper tools in order to generate an executable?

I'm using the OSS version so I am using the MinGW compiler. I've looked at the CLI for the Gnu tools and I am sure I could begin stringing togather an application by compiling/linking each source file manually but what a PITA.

Using the given toolset, what would be the best way to begin?

Thanks

qmake generates makefiles from much simplier .pro files with all of the rules that Qt needs for compilation.

Thanks for the speedy reply.

I've read those articles and tried to build a simple, single file application but I am getting the following error:

mingw32-make: *** No rule to make target `test.pro', needed by `Makefile'.  Stop.

mingw32-make: *** No rule to make target `test.pro', needed by `Makefile'.  Stop.

What am I doing wrong? I've Googled but nothing really helpful.

How does your .pro file look like and what how did you invoke qmake?

[Hockey]

Edit It just occured to me to look inside my makefile and see if the path were inside the makefile. It seems as though the makefile is just referencing the test.pro and NOT including the path. Ise the environment variables for the MinGW and Qt binaries, do I just add my project path to environment variables as well? I would need to keep the path in the qmake command thought, correct?

This is the contents of my project file:

CONFIG += qt
SOURCES += main.cpp

CONFIG += qt
SOURCES += main.cpp

To copy to clipboard, switch view to plain text mode 

I copied it verbatim essentially from the tutorials...

I invoked qmake with this command:

qmake.exe -o c:\test\Makefile c:\test\test.pro

qmake.exe -o c:\test\Makefile c:\test\test.pro

Everything OK so far. How did you invoke make?

[Hockey]

make --makefile=c:\test\Makefile

make --makefile=c:\test\Makefile

To copy to clipboard, switch view to plain text mode 

I've tried several switches but no luck...

[jacek]

Does it work if you invoke:

cd c:\test\
make

cd c:\test\
make

To copy to clipboard, switch view to plain text mode 

?

Zing!!!

That did the trick. Although it compiled as release not debug. Does this mean I have too add my project path to environment variables?

Most likely it's because you don't have the debug version of Qt libraries. Look for "Build Qt libraries in debug mode" or something similar in the Start menu.

No, I've just reproduced your problem on my system. It seems that qmake generates Makefiles which expect that the .pro file is in the current directory. So you just have to make sure that your project's directory is the current one.
