Before you build the Qt library and example programs, you must run the
"configure" script to set the platform information and other build
settings.  You can use the -platform option to specify the operating
system and compiler you are using.

Supported platforms and compilers:

  aix-g++       hpux-g++       linux-g++       solaris-cc-64    win32-g++
  aix-xlc       hpux-g++-64    linux-g++-64    solaris-g++      win32-icc
  aix-xlc-64    irix-cc        linux-icc       solaris-g++-64   win32-msvc
  freebsd-g++   irix-cc-64     macx-g++        tru64-cxx        win32-msvc.net
  freebsd-icc   irix-g++       macx-pbuilder   tru64-g++
  hpux-acc      linux-ecc-64   solaris-cc      win32-borland

Compilation problems:

  If you experience problems compiling Qt 3.x consult the platform
  notes found at http://www.trolltech.com/developer/platforms/ where
  we post workarounds and known issues as we become aware of them.

Example:

  ./configure -platform irix-cc-64 -shared -debug

Customization:

  You can create your own custom configuration by adding new files
  to the mkspecs directory.  Use existing similar configurations
  as a starting point.
