All,

Does anyone know if it is possible to generate a cross build of gcc
with ada support that targets an ARM processor, specifically a gumstix
embedded board with Marvell Xscale PXA270? The host is an x86 machine
running ubuntu. If it is possible does anyone have a quick step by
step what do i need to build and where are the possible traps? I have
tried using the build environment for the gumstix with no success, gcc
always fails with a rather cryptic error message usually involving
some kind of source code error. Any help would be greatly appreciated.

Thanks,

Bryan Campbell

Thanks! I'm very interested in this as well. Some of my folks tried
pretty hard and could not get it to work, but that was 2 versions of
gcc ago. We could build a cross-compiler, but never a usable runtime,
so we gave up. I wrote AdaCore asking what it would cost for them to
do the work and received no reply.

Bryan, Gene,

if you want to give it a try, I produced a quick patch for the latest
GCC SVN trunk which may work or may not work.

You must:

- fetch the latest GCC sources from the FSF, SVN trunk, see

http://gcc.gnu.org/svn.html

to retrieve the sources

- apply the patch found at

http://www.rfc1149.net/tmp/arm-linux-gnat-port.patch

- build and install a native Ada+C compiler from those patched
sources

- build and install a cross compiler from those patched sources
using the compiler built previously (it is important to have the
cross-compiler built from a native compiler using the same
version)

I do not have any ARM board to test it. Please keep me informed
privately (maybe keeping each other in Cc:) of how it went, so that I
can add this patch to the GCC sources if it is working for you.

Sam

Hi,

I am currently playing with RTEMS 4.8.99 targeted for the Game Boy
Advance which is ARM based. I used the instructions found at
http://www.rtems.com/wiki/index.php/RTEMSAda to build the cross
compiler. My setup is Slackware-current with GCC 4.2.3.

I tried those instructions prior to posting here but the platform I am
building for uses posix threading instead of RTEMS threads and the gcc
compilation failed after changing the threading model in the
configuration. The other complication is that the kernel is built for
this target using the openembedded bitbake method which I don't quite
understand yet.
