Error use gcc linking  RVCT2.2 c libraries

Unknown huaiyin

Note: This was originally posted on 19th March 2007 at http://forums.arm.com

I use RVCT2.2 armcc to complier files and get a library.
Then to use gcc link the library, but get
Error:
  undefined reference to '__aeabi_uread4'
  undefined reference to '__aeabi_uwrite4'

I know that the armcc and gcc are different to link the fwrite() or fread() functions,
RVCT 2.2  armcc use an optimized one, i,e. __aeabi_

But , how to solve such problem? 
Have  any simple armcc compiler options to avoid such questions?

Any suggestion approciated.

    It is not the headers path problem.

    The reason is that the gcc and armcc has different functions name for the stdio function libarry.  RVCT 2.2 armcc use an optimized one, i,e. with a prefix. __aeabi_

    Does any compiler options for armcc to avoid such problems?[/color]

    Thanks!
