Hello to all!

I've downloaded the opensource qtopia 4.2.4 and once I try to configure it, it get:

Qt Code: 
  1. root@borg:/usr/src/qtopiaBuild# /usr/src/qtopia-opensource-4.2.4/configure
  2.  
  3. This is the Qtopia Open Source Edition.

  13. Qtopia is using the following locations:
  14. Qt          SOURCE tree = /usr/src/qtopia-opensource-4.2.4/qtopiacore/qt
  15. Qt          BUILD  tree = /usr/src/qtopiaBuild/qtopiacore/host
  16. Qtopia Core SOURCE tree = /usr/src/qtopia-opensource-4.2.4/qtopiacore/qt

  19. Qtopia      BUILD  tree = /usr/src/qtopiaBuild
  20. Your Qtopia source tree has a build in it. This must be removed. Please wait...

Can someone help me?? Do I need to install 32 bit version of compiler and if so, is it possible that two different versions of gcc coexist on same linux box?
