[ECOS] GCC 4.3.2 toolchains for arm, cortex, mips, powerpc

[ECOS] GCC 4.3.2 toolchains for arm, cortex, mips, powerpc

[Øyvind Harboe]

I've been toying around with building GCC toolchains(as one does...).

They are ready for testing if anyone is interested:

http://mail.zylin.com/pipermail/zylin-discuss_zylin.com/2008-September/000557.html

Feedback welcome!



W.r.t. eCos libstdc++ posix threads support they are not available here
as they require being built for the specific HAL in question. libstdc++ w/posix
threads works great under eCos though :-)

Øyvind, thank you for your contribution. Before to start download I read
a point on the http://www.zylin.com/gccbinary.html page:

  The binaries contain the authoritative source of what build options
  that were used.

Does it mean what everyone can find all build options (and patches if
any one were applied) inside the bloat archives to replicate your builds
from GNU sources? Is there a guide how to build the stuff in the
archives? Like as an official eCos guide:
http://ecos.sourceware.org/ecos/build-toolchain.html

If it does mean, can you please to public 'the authoritative source'? in
text/html form on your web? Thank you.

Sergei

Yes. Run gcc -v.

As in "authortative" meaning that if I wrote something on the web
page, the actual options used *could* be different. Cycle times
to do these sort of builds are *long* so it is something I tinker
with occasionally.

Nope. I'm still learning here... I may write up some more once I get
better hang of this whole building GCC thing... The link above is
one of the more useful links that I found though.

You can download them from the GCC mirrors, why would you want
them from Zylin?

Don't you know where the GCC mirrors are?

It's wondeful to know about dumping GCC build options and it's specs
after downloading XXL archive :-) I have 128/32K connection. And what's
about binutils, newlib, gdb? Did you configure that using the prefix and
the target/host/build triplet only? I guessed you didn't.

Yes, I do. More that I have the copies of the referenced packages on my
disk and therefore I asked you about your steps (guide ?) just in a text
form, but no 7-zip :-) to replicate any build.  I dislike RTBF and
most like UTSL
http://web.bilkent.edu.tr/Online/Jargon30/JARGON_R/RTFB.HTML
http://web.bilkent.edu.tr/Online/Jargon30/JARGON_U/UTSL.HTML

You asked about a feedback. And I guess that the testers would compare
their build steps with your ones.

In any case, thank you for your spent time, bogomips and disk storage to
contribute the toolchains.

I wonder what I'll got then... GCC/newlib/binutils/gdb sources?

It takes time to test & document all this, but my intention is to get more info
on the web page itself once the dust settles.

I'm travelling down a lot of blind alleys while putting together this.

Once the dust settles and I'm reasonably satisified that my scripts
are helpful to anyone else, I'll upload them.

Sources not included in that download.

If you tought 34mByte was big for a binary, how about a 150mByte arm-elf
multilb download w/zip, which is why I'm using .7r for Windows binaries :-)

Re: [ECOS] GCC 4.3.2 toolchains for arm, cortex, mips, powerpc

[simon.kallweit]

Hi

I just tried to compile my work-in-progress Cortex-M3 port with your 
arm-elf compiler. Without much luck though, as it seems that your 
compiler is compiled for hardware floating point architectures, or did I 
get something wrong? Also it occured to me, that you got a dependency to 
the mpfr library, which should not really be there I guess. At least it 
wasn't with all the other toolchains I used/built so far.

Did you do any tests based on Cortex-M3? Or only Cortex-A8?

Best regards,
Simon

Would you be willing to help out testing and post a bit more detail on what
 you did, what you expected and your results?

Post to http://zylin.com/mailman/listinfo/zylin-discuss_zylin.com, I believe
the ecos-discuss mailing list has interest in a *working* Cortex toolchain
rather than the work in progress as it is now :-)

> Did you do any tests based on Cortex-M3? Or only Cortex-A8?

Nope. It is ready for such testing and I appreciate your feedback.
