Re: Cross-compile Applications for 860 on x86

      I want to cross-compile a very simple test program which have only one line:

             printf("jsut a test.");

I used puts("Brendan was here") as it is much simpler, but printf should work as well.

 But  the powerpc-linux-gcc seems to complain I lack of "crt1.o".
So what other tools I need to cross-compile my application except the powerpc-linux-*?
Thanks  very much.

I have crt1.o, crti.o and crtn.o in $prefix/$target/lib.  Initially they were put there
when I unpacked the rpm files from the yellowdog distribution.  I was following some
instructions from Kai Ruottu when I was trying to get my cross-compiler built.  I think
I built glibc libraries from the source afterwards which should have replaced those ones
but I'm not sure.
Have you built glibc yet ?

Yes but failed. I following the following steps:

Since the glibc package is very very large, locating the file where errors occur (ie, where
struct singcontext is defined?) is a bit difficult.
Do you have any experience?

I do not have the solution to your installation problem but I would just like to make a
suggestion for CC= when configuring for your mpc860 target.  Try CC="powerpc-linux-gcc
-mcpu=860" if the 860 is not your default processor when invoking gcc.  I think you can do
this at the configuration stage when building your cross-compiler or you can manually change
the specs file.
