Hello Robert.
I'm building toolchain for AT572D940HF Atmel chip. It's ARM9 combined
with DSP. I'd like to build toolchain for ARM9 (ARMv5tej) with
-msoft-float support, EABI and full glibc ,to support all stuff
connected with PREEMPT_RT patch - especially librt.
Now I've downloaded:
ptxdist-1.99.11 and ptxdist-1.99.11-patches.
and
OSELAS.Toolchain-1.99.3
I've selected
./ptxconfigs/arm-v5te-linux-gnueabi-gcc-4.3.2-glibc-2.8-binutils-2.18-kernel-2.6.27-sanitized
I need toolchain with -msoft-float support and EABI.
Unfortunately there is an error about mismatch in the linux-kernel
headers. My Host PC has linux-kernel of 2.6.24 and not 2.6.27. My target
is working under 2.6.26.8-rt14 kernel.
The error is in building of NTPL library, after successfully compilation
of gcc compiler.
How can I provide proper kernel headers?
Now I'm trying with
arm-v5te-linux-gnueabi-gcc-4.1.2-glibc-2.5-binutils-2.17-kernel-2.6.18
ptxconfig. I hope that this will be sufficiently new to provide priority
inheritance, futexes , librt with all features.
I'm building it now and hope that I won't encounter any problems.
Regards,
Lukasz

Now some explanation about uClibc. I know that this C library lacks of
many features (for instance NTPL support for ARM). Unfortunately, for
ARM architecture, there is nice utility -> buildroot for building
toolchain and root filesystems.
You can use ptxdist do do almost the same.
I've tried pxtdist tool from pengutronix.de, but I cannot build proper
toolchain without errors for my Atmel's ARM9 device (ARMv5tej arch to be
precise). Or saying it in another way -> I gave up after spending some
time and moved back toward working uClibc.
Well, you could have reported that to the OSELAS.Toolchain maintainers :)
What kind of problem do you see? We are using the the v5te toolchain
quite intensively on AT91SAM9260 and AT91SAM9263 without problems.
So send us your error output and let's see what we can do. The ptxdist
mailing list is probably the right list for that kind of discussion.
