Well let me answer with another question:

I have a cat. Is she black or withe?

...maybe it would be helpful if you tell us which compiler do you have! And a general answer: use qmake with the corresponding SPEC and then simply compile.

Ok,Excuse me
It is the g++-linux for cygwin 2.5
And what is SPEC and how can i do the thing you mentioned?
thanks again

when qmake generates the make files it has to know for what plattform it should be done, so use QMAKESPEC or the -spec flag to set your environment: linux-***. then normaly run make under cygwin and all should be done.

I entered commands below in my project directory:

qmake -project
qmake -spec linux-g++ calc++.pro

---

then inside the cygwin shell ,in the project directory,I entered the make command but it answered:

Quote:

---

Makefile:104: *** multiple target patterns. Stop.

---

what should i do?
And I thought I should use a cross-compiler like cygwins g++-linux.
And could you explain about the OS modes in qmake?
thanks

You know.I really need the answer of this question.thanks again

i think a cross-compiler is one which compiles for a particular target machine/architecture, not the host machine.. what is the target for your cross compiler

Its Linux and my goal is exactly compiling for a target OS.

I'm going to ask the dumb question here: Leaving Qt aside for the moment, have you been able to cross-compile a simple Hello World application on Windows for Linux?

With your last Makefile error you could try looking at the output of

Code:

---

make -n

---

to see what it is actually trying to do.

It gives the same error with the difference that it prints 66 instead of 104 and it is the same with make itself,too.
