Yeah thats a point to be noted. So i build with target sparc-solaris.
Is that correct.

Few questions
1) I can build binutils for sparc-solaris, it works fine.
2) i can build core-gcc for sparc-solaris
3) How do i build the complete gcc for sparc-solaris. I don't have the
headers . I can't use linux headers or glibc as i don't have them on
the target machine.
4) Say if  i use newlib for target sparc-solaris, then i will have to
write linker scripts.
5)
Now how do i compile a hello world program executable and run it on my
sparc solaris 10 machine.
