cross compiling m68k -> ppc

cross compiling m68k -> ppc

[luther]

Hello, ...

as reported yesterday, i was finally able to compile the cross compiler.

after that i triied to compile a simple hello world program. and get
a ld error. ld complains about not finding crt1.o. I made a find / -name crt1.o and didn't find any file with that  name.

Friendly,

Right.  Now you have to find c-startup and library files for your target.
Presumably you can snarf them from an existing system.  Else you'll
have to hack up a set on your own.

You need to compile (g)libc for the ppc target too, of course.

Could you be persuaded to try cross building a native linux-ppc compiler
with the linux-m68k --> linux-ppc one?

That typically a ctr0.o file that initialises anything needed to use the C
library.

C-startup files are usually included in a C library sources of some
kind.  They do things like set up the stack pointer and other global
registers, start the dynamic loader, and call main.

I don't know.

No.  The kernel is completely standalone and self-contained.  All you need
are the headers that come with the compiler.

i suppose if i cross compuile some library (glibc or newlib for example) i will get the libraries files, but wath is c-startup and where do i get it.

Also, if i want to cross compile a linux kernel do i still need this libraries ?
