undefined __aeabi_unwind_cpp_pr0 error

Hello

On trying to compile the kernel 2.6.22.19 with the gcc 4.3.2 for arm
processor, 
gcc -v is as below 

Using built-in specs.
Target: arm-unknown-linux-gnueabi
Configured with:
/home/developer/devel/crosscompiler/targets/src/gcc-4.3.2/configure

--enable-long-long --enable-target-optspace
Thread model: posix
gcc version 4.3.2 (crosstool-NG-1.2.0+svn_trunk@1176) 


I am getting the below error 
Can u please tell me if some extra flags, to be used in compiling the gcc,
so that the "__aeabi_unwind_cpp_pr0" function gets included with the libgcc.

In kernel include/linux/iffies.h there are many macro divisions and i have
replaced one of these macros with a varable, and on compilng the kernel , it
complains of the undefined __udivdi3 __divdi3 functions , because of this ,
i am trying to link those functions in the libgcc.a , on doing so i am
getting the below error.

Re: undefined __aeabi_unwind_cpp_pr0 error

Hi !

I'm having the same kinds of errors, trying to compile u-boot with gcc from
current testing from emdebian
$ arm-linux-gnueabi-gcc -v
[...]
gcc version 4.3.3 (Debian 4.3.3-3)

I found some solutions :

For this :

Look at the ABI you are using (gcc flags for compilation)
Here are some information : http://wiki.debian.org/ArmEabiPort

I had to replace 
PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,-mabi=apcs-gnu)
with
PLATFORM_CPPFLAGS +=$(call cc-option,-mapcs-32,-mabi=aapcs-linux)
(removing is also OK)

For this :

For this, you must either define a raise function, or, as I did for uboot,
define the raise symbol as an alias for an existing one.
I used what is done for the uboot version for openmoko :
PLATFORM_LDFLAGS += --defsym raise=hang


But for this :

I'm still looking around for a solution.

If anybody has one, he's welcome to reply to this thread !
Thanks.
