can any one tell me how to intall these two packages?

i have been try to do for 4 hous. it still not working.

where I am up to now

my vs can compile now, but it will give me a error:

Qt Code: 
  1. fatal error LNK1181: cannot open input file 'qtmaind.lib
To copy to clipboard, switch view to plain text mode 

then i go to that folder, there is no any lib files

so I guess i need to build it with vs

then I open cmd and go:

Qt Code: 
  1. c:\qt\4.5.0-vc\qt> configure -platform win32-msvc2005
To copy to clipboard, switch view to plain text mode 

it give me a error:
Qt Code: 
  1. c:\qt\4.5.0-vc\qt\include\qtcore\../../src/corelib/global/qglobal.h(45) : fatal
  2. error C1083: Cannot open include file: 'stddef.h': No such file or directory
  3. NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio 8\VC\bin\
  4. l.EXE"' : return code '0x2'
  5. Stop.
