which host to compile qt4.5.2 embedded

hi,

i would like known if i must to compile qt for my board in the host pc
ubuntu or in  my board Micro2440 ?

thanks in advance.

Haven't heard of anyone managing to compile stuff directly on the target. 
Does not seem to be common practice for "embedded" type systems.

Find an electronic copy of "Building Embedded Linux Systems.pdf", the
author does an excellent job of explaining how all this stuff hangs
together.

thanks
