Help with an Wierd Error

[Balaji.Iyer]

Hello Everyone,
      I am trying to build an OpenRISC port of GCC. I am not getting much response from the OR32 people, and this error sounds a bit generic from google searches so I thought if someone would know how to solve it.

I build binutils, gcc and newlib  as they mentioned in the or32 website. But now I am getting this wierd error when I am trying to compile "Hello World" program

It looks like a case of one-too-many underscores prepended to symbol 
names.  The default for ELF is to not prepend an underscore.  The 
default for COFF is to prepend an underscore.  Check USER_LABEL_PREFIX 
which should be empty for ELF (default definition in defaults.h file). 
Check ASM_OUTPUT_LABELREF which should use %U and not an explicit 
underscore (see defaults.h file).  Check for usage of the 
-fleading-underscores option (should not be used).  Check for header 
file inclusion to see if something is out of place, such as a use of 
svr3.h when svr4.h should be used.

Also check to make sure that gcc, gas, and gld all agree on whether a 
symbol is prepended with an underscore or not.  If gcc does it but gas 
doesn't, then C code calling assembly language code may fail because of 
the mismatch.
