Do you have any odd things in your program? For example:
Code:
char Buff[3];
short Num = *(short*)(Buff+1);
will work fine on X86 processors but will crash on ARM.
@moofang: I did deploy the ARMEL target. Also, gtkhelloworld works fine on my n900.

@slobodsky: Thanks. I'm a newbie, so forgive the ignorance:
1. How do I determine which version of QT is on my device?
2. Which is the standard version of QT that's distributed with the latest Fremantle image?
3. Is there a compatibility flag on qmake that I can use to generate binaries that link with earlier versions of QT?

Thanks in advance!

@andre: I thought the meaning of what I said was implied, but thanks for pointing it out anyways.
