Error use gcc linking RVCT2.2 c libraries

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.

I had the same problem and i tried the code sourcery's gcc. All _aeabi errors are cleared. but i got another error:

"conflicting defenitions of wchar_t "

but I'm not using any wide chars in my code. Is there any solution for that error? Is it a compiler issue?

I don't think it is a compiler issue.
It could be somewhere linker is conflicting with the multiple definitions. Just check the inbuilt libraries included and any definitions in multiple files.
