Hi all.
This is my first post to this list. Greetings to everybody.
I am trying to compile gcc 3.2.3 under cygwin(WinXP) using gcc 3.2
(20020927 pre-release). I want to make a cross compiler for ARM7TDMI,
producing old ABI objects.
I can't afford using the new ABI because I have to link my code with
many libraries using the old ABI. My code has to be linked by other code
compiled with ADS 1.2 (old ABI).
So I did this:
I downloaded binutils-2.14.
configure --target=arm-none-oabi --with-cpu=arm7tdmi --prefix=/usr/local
make
make install
Everything worked fine.
Then:
I downloaded gcc-3.2.3 (just the core, no cpp, ada java or other langs)
configure --target=arm-none-oabi --with-cpu=arm7tdmi --prefix=/usr/local
make
Configuration went ok.
While making I kept getting "cpu" re-asserted warnings and I finally got
thess errors:

This seems to be ARM code but the -mthumb option makes me think that
there is something going really wrong here.
Can anybody help me with this? Has anybody ever come across anything
similar?
Thank you all,
