GNAT for arm-elf target?

GNAT for arm-elf target?

[Andreas Schwarz]

Hello,

can I expect to get a usable Ada cross compiler for ARM simply by 
compiling gcc with --enable-languages=c,ada --target=arm-elf, or is 
there more to it?

Thanks
Andreas

Even for vanilla C building cross compilers can (sometimes) be a bit of 
a pain. (http://kegel.com/crosstool/)

You will need cross binutils as well. Also for a real full Ada I would 
expect that you need the OS listed in the --target someplace since it 
will be difficult to build the runtime without knowing that data.

If you can afford it I'd really recommend getting a supported version 
from AdaCore.

They currently list arm vxWorks as a supported platform.

If you are looking for a non-runtime/non-tasking version of the compiler 
it can be a bit easier to get everything built.

I also poked around the rtems website (www.rtems.com) since they provide 
pre-built RPMs for various targets. They have a bunch of Ada cross 
compilers but for Arm they do not currently show gnat support.

If you are just looking for something to play with (v.s. something for 
real "work") then I suppose just giving it a try would be fun.
