Hi Everybody I was wondering if enybody could tell me how to optimize Qt for the mini2440 i have actually tryed like 1 million different settings but none got me to a result i could live with actually i tryed using -mach and -mtune but neither of those seems to work! tryed using : -msoft-float -D__GCC_FLOAT_NOT_NEEDED -march=armv4 -mtune=arm920t and CFLAGS for release but all i get is: ./../corelib/codecs/qisciicodec.cpp:1: error: bad value (armv4) for -march= switch ../../corelib/codecs/qisciicodec.cpp:1: error: bad value (arm920t) for -mtune= switch so i was wondering if anybody have any idea or hint on how to optimize qt... which version of qt is suggested for the device?

Optimized Qt for Linux
@davef yes it does make a differance ARMv4: this supports only 32 bit ARMv4 instructions ARMv4T: 'T' stands for Thumb. Thumb is the ARM 16 bit instruction mode ARMv4I: 'I' stands for Interworking. This allows for 32-bit and 16-bit instructions to co-exist As for the other ARM processors: StrongARM (SA1110): only supports ARMv4 instructions ARM920T, etc.: Typically supports all three variants
