[Efi332] Building newlib/libgloss for MPC555

[David Eicher]

Hello, thanks again for the input:

1) I chose usr/local/power-elf because I thought that was what the readme
file at source.redhat.com was telling me to do. It is definitely not the
only thing I have misinterpreted.

I moved it to usr/local/newlib-1.13.0.

I followed the instructions in the readme exactly and created a new
directory called newlib-ppc-aout (following their convention in the
instructions). 

I ran configure using --target=powerpc-elf

It did better this time, it found my compiler/linker/etc. But still decided
I don't have a cross compiler. Hmmmm, not sure what is going on there.

Maybe issue 1 and 2 below are corrected, can't tell from the configure
output for sure, I suppose I'll run make and see what happens. Issue 3 is
fixed. 

I picked the name newlib-ppc-aout because the readme file with newlib gave
mewlib-m68k-aout as an example, so I just used their suggestion with ppc.
Bad idea? 

Not sure what you mean by obsolete wish, but there is abviously something
going on that I don't understand. I thought I wanted to build the newlib
with code for the ppc (powerpc), is that not correct? And I want to modify
libgloss to be an interface to my hardware, so I need to compile that for
powerpc too, no? If I have this all mixed up, that could be why I'm not
getting much to run.

Thanks for the input on the order to do things, there is no info on that in
the readme file. So I should run make and get newlib to build before I
modify libgloss. I suppose the linker errors will tell me what I need in
libgloss.

I know this is bad, but I don't even have a source level debugger working
yet. So far I've debugged everything using OCDCommander in assembly
language. I'm hoping to get gdb and insight working soon, and then I'll have
to figure out how to tell if where the source is. Thanks for the hints.

Well, I kicked off make, it's been running for 5 minutes and is showing no
signs of finishing..., it must be doing something good. I hope I don't run
out of disk space. I forgot to ask how to limit the scope of this build.

Regards,

Dave

Give powerpc-eabi -> powerpc-elf a try. Not sure if configure treats it
the same anyway....

Probably the same cuase.

Exactly.
