[okl4-developer] build-system-problems with okl4 3.0 and gta01

[Dennis Gessner]

Hi,

because of an bug inside okl4 2.1.1, this morning I had to switch to
okl4 3.0. Now I have some problems with the build system/sdk.

Can anyone just try this out - maybe (I'm almost sure) this is my own
fault and I would like to know what I am doing wrong.

I would like to use okl4 3.0 with the gta01 device, which is based on
the ARM920 core (ARMv4).

I tried the following:

I've downloaded the precompiled cross-compiler
arm-linux-gnueabi-4.2.4.tar.gz and installed it into my system.

- Download the complete sourcecode of okl4.
- tools/build.py machine=gta01 project=iguana wombat=true debug_trace=5

-> caused an error:
./okl4_3.0/linux/rootfs-2.6.24-v2/SConscript:32 Error: name
'oklinux_tests' is not defined

so I changed the command to (regarding some posts on the mailinglist to
eliminate some other errors):
- tools/build.py machine=gta01 project=linux wombat=true
enable_fastpaths=False debug_trace=5 PYFREEZE=False

-> caused an error:
scons: Reading SConscript files ...
OK Linux library dependencies: ['mutex', 'l4e', 'l4', 'gcc',
'circular_buffer', 'oklinux', 'atomic_ops', 'okl4']
build okl4fs? False

scons: done reading SConscript files.

Assembler messages:
Fatal error: Invalid -march= option: `armv4t'
scons: *** [build/pistachio/l4kernel/object/src/asid.o] Error 1
scons: building terminated because of errors.

so I thought... ok, maybe I should follow the mailinglist and really use
the sdk :-) ...

- Download ARM920t 3.0
- Followed the instructions inside the tutorials "SDK Tutorial: Hello
World" and some parts of the mailinglist
- copied ./examples/singlecell to my working directory
- export OKL4_SDK_ROOT=...
- make

-> caused an error:
make -C hello KERNEL=micro BUILD=debug

----

What else can I do to get okl4 3.0 working?

Another small question:
Why isn't there a linux/kernel-2.6.24-v2/l4linux_config_gta01_cell ? As
little workaround (because of he wants to have this file), I just copied
the l4linux_config_gta01 over it ...

Best regards,
Dennis
