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
