[Qt-interest] cross platform

[Raffael Maurer]

Hi,

i need to develop a c++ cross-platform project for mac and linux on both 
32 bit and 64 bit machines and i was wondering if you you would suggest 
Qt for it. i  would need any type of string-, time-, and other simple 
classes from Qt but i only want to develop a console application and 
would not really need all the features. Would i really need to use qmake 
and the Qt-creator iDE or can i simply include the Qt-headers in my 
project and use q++ to develop still independently of the platform?
i have to deploy structures and read/write binary files and could also 
use the c header posh.h but in this case i would have to take care of 
endianness and i guess the number of bytes per data type.
Any help would be appreciated -i have never developed a cross platform 
application for a 32 and a 64 bit machine.

Thank you,

Raffael
