[okl4-developer] Help regarding the OKL4 port to the Qemu Emulator

[Amrit Acharya]

Hi Nicholas,

I downloaded the official OKL4 3.0 source from the wiki. I tried building
for the versatile platform using :

 *tools/build.py machine=versatile project=examples example=hello
PYFREEZE=False TOOLCHAIN=gnu_arm_eabi_toolchain* and i got the following
error :

[CXX ] build/pistachio/l4kernel/object/src/init_script.o
cc1plus: warnings being treated as errors
pistachio/src/init_script.cc: In function 'void ki_assign_irq(space_t*,
ki_assign_irq_t*)':
pistachio/src/init_script.cc:647: warning: type-punning to incomplete type
might break strict-aliasing rules
scons: *** [build/pistachio/l4kernel/object/src/init_script.o] Error 1
scons: building terminated because of errors.

On trying with :
* tools/build.py machine=versatile project=examples example=hello
PYFREEZE=False TOOLCHAIN=gnu_arm_eabi_toolchain
pistachio.TOOLCHAIN=gnu_arm_toolchain *, I get the following error:

scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
[CXX ] build/pistachio/l4kernel/object/src/asid.o
cc1plus: error: invalid parameter `large-function-growth'
scons: *** [build/pistachio/l4kernel/object/src/asid.o] Error 1
scons: building terminated because of errors.

which is the same I was getting while using androidsim and the ported
version of OKL4.
