            Target: ARM 920 (AT91RM9200)
             Build: 2009.11
           Summary: uClibc (re)building fail
           Product: buildroot
           Version: 2009.11
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: blocker
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: peter.stosz at freemail.hu
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


1) Download BR2009.11

2) Customize with menuconfig, target ABI is OABI

# BR2_iwmmxt is not set
BR2_ARM_TYPE="ARM920T"
# BR2_ARM_EABI is not set
BR2_ARM_OABI=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_TUNE="arm920t"
BR2_GCC_TARGET_ARCH="armv4t"
BR2_GCC_TARGET_ABI="apcs-gnu"

3) Customize Linux(2.6.27), target is ABI is OABI
CONFIG_HZ=128
# CONFIG_AEABI is not set
CONFIG_ARCH_FLATMEM_HAS_HOLES=y

4) Customize BusyBox(1.15), build system, everything is OK, target system boot
and running

5) If I touch (nothing modify) the uClibc config and try to (re)make a system,
I get something: (.ARM.exidx+0x0): undefined reference to
`__aeabi_unwind_cpp_pr0'

uClibc's config:
#
# Target Architecture Features and Options
#
TARGET_ARCH="arm"
FORCE_OPTIONS_FOR_ARCH=y
CONFIG_ARM_OABI=y
# CONFIG_ARM_EABI is not set
# USE_BX is not set
# CONFIG_GENERIC_ARM is not set
# CONFIG_ARM610 is not set
# CONFIG_ARM710 is not set
# CONFIG_ARM7TDMI is not set
# CONFIG_ARM720T is not set
CONFIG_ARM920T=y



6) Clean, working config (without step 5), I add some options (target toolchain
building) in buildroot config (without touching uClibc config), and start make
process, I get this:

--- Comment #1 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com>  ---
I finally took the time to try to reproduce the issue today. So what I did is :

 1) Build an ARM OABI toolchain + Busybox system, was successful
 2) Touched uClibc .config file
 3) Restarted the build, and it was successful again

In other words: I haven't been able to reproduce the issue you're describing.
Since the bug has been opened quite a long time ago, it might be possible that
we fixed it in the mean time. Or that I didn't managed to reproduce it because
I didn't fully understand the reproduction procedure detailed below.

As the bug is rather old and since I didn't manage to reproduce it, I'll close
it as WORKSFORME. However, Peter, if you can still reproduce it, do not
hesitate to reopen the bug, and attach your Buildroot .config file. Thanks !
