[Buildroot] Compiler for arm7tdmi

[Buildroot] Compiler for arm7tdmi

[Jon Smirl]

I'm not having any luck building a compiler for arm7tdmi. I have the
static_flat file format selected, I couldn't get Elf to build. My goal
is to compile Contiki for a Freescale MC1322x.

Now I'm hitting this problem with __fini_array_end using git head.

I don't think that flat support is working in the official repo.
I once started to add support in my repo.or.cz/w/buildroot tree, but
even that is not finished yet.

patches welcome..

Which format should I be using for arm7tdmi onto bare hardware?

The elf target fails building with:
cc1: error: unrecognized command line option "-mfdpic"

sounds like a misconfiguration to me (of uClibc).

I tool all of the defaults except for setting my CPU to arm/arm7tdmi.

What should I try changing?

make uclibc-menuconfig
and then search for FDPIC, i.e. type, literally:
/FDPIC
(followed by a newline).

There are four choices for output file format:
( ) FDPIC ELF
( ) STATIC FLAT
( ) STATIC FLAT (sep-data)
(X) SHARED FLAT

( ) FDPIC ELF
This is the default. Causes -mfdpic compile error.

( ) STATIC FLAT
I tried this one and got the _fini_array_end compile error.

(X) SHARED FLAT
This is currently building.

I think that any flat will not work in current buildroot.
You can only use elf, but that will not help you on bare metal AFAIK

Not a uClibc issue though.
