[okl4-developer] How to compile the OK Linux root file system ?\

[Hugues Balp]

Thanks for your remark ,

In fact I have also tried with other tool chains:

1) with a gcc-3.4.5-glibc-2.3.6.arm-softfloat-linux toolchain which 
doesn't support eabi and nptl
and I got the same error on rootfs-2.6.24-v2....

It was not possible to patch it with glibc-port-2.3.6 because the arm 
and nptl support was not included
in such old glibc-port version...

2) I have also tried to apply a patch on crosstool-0.34 from montavista
to compile a gcc-4.1.1-glibc-2.5 gnueabi + nptl arm tool chain but 
without success.
( here is the URL of this patch: 
http://sources.redhat.com/ml/crossgcc/2006-12/msg00076.html )

3) with a gcc-4.2.4-glibc-2.7 gnueabi + nptl arm toolchain

but some warning stop the compilation in case the option -Werror is used 
with arm-...-gcc.

when I comment this option, several warning are raised such as

pistachio/src/interrupt.cc:217: warning: type-punning to incomplete type 
might break strict-aliasing rules
arch/arm/pistachio/kdb/tlb.cc:325: warning: deprecated conversion from 
string constant to 'char*'
build/pistachio/include/kernel/kdb/console.h:98: warning: conflicting 
types for built-in function 'putc'

and the compilation process stops with the following error:

/opt/crosstool/gcc-4.2.4-glibc-2.7/arm-unknown-linux-gnueabi/bin/../lib/gcc/arm-unknown-linux-gnueabi/4.2.4/libgcc.a(_dvmd_lnx.o):

undefined reference to `__aeabi_unwind_cpp_pr0'
scons: *** [build/pistachio/bin/l4kernel] Error 1
scons: building terminated because of errors.

Can you please explicit to me the toolchain we have to use to be able to 
run the POSIX test suite ?
Do you use another process to build the crosstool chain ?

Thanks in advance for your answer,

Hugues Balp.
