Re: Qs about runtime support libs like crt0.o

Exactly what CPU are you using?

1)    How exactly did you build GCC?
   Where did  you get <stdio.h> from - when you built arm-elf-gcc?
       Did you borrow it from /usr/include - That is a bad thing!

2) Generally to build GCC you do it in two stages.
        Stage 1 - You build a plain C only compiler.

     Important config options:
            --with-cpu=<THE_EXACT_ARM_YOU_ARE_USING>
            --with-newlib
            --disable-nls
           --enable-threads=no
          --enable-symvers=gnu
          --enable-__cxa_atexit
         --enable-languages=c
          --disable-shared

Use "make all-gcc" then "make install-gcc"

Anything more - has mental issues...


So, there's some uncertainty here for me. I'm trying the following:

../configure --prefix=/usr/local/myarm --target=arm-elf --with- cpu=xscale --with-arch=armv5te --with-float=soft --with-newlib -- disable-nls --enable-threads=no --enable-symvers=gnu --enable- __cxa_atexit --enable-languages=c --disable-shared

I notice you didn't specify --target, but "make all-gcc" complained about not knowing --with-cpu=xscale without it. I'm trying right now with --target to see if that makes things better.

I'm using an XScale PXA320, which the docs say is arm v5te but I don't know more than that.
