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 :

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, 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.
