Hi, all:
I am porting android4.0 to our board, but found the binaries in /system/bin
can not be executed.
It always shows "Segmentation fault."
# ./mediaserver
Segmentation fault
# ./wpa_cli
Segmentation fault
# ./vdc
Segmentation fault
I used the defalut config:
============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=4.0.1
TARGET_PRODUCT=full
TARGET_BUILD_VARIANT=eng
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=arm
TARGET_ARCH_VARIANT=armv7-a
HOST_ARCH=x86
HOST_OS=linux
HOST_BUILD_TYPE=release
BUILD_ID=ITL41D
============================================
I traced with strace
# strace ./vdc

===========================
And find the toolchain has been changed to
ifeq ($(strip $(TARGET_TOOLS_PREFIX)),)
TARGET_TOOLS_PREFIX := \
prebuilt/$(HOST_PREBUILT_TAG)/toolchain/arm-linux-androideabi-4.4.x/bin/arm-linux-androideabi-
So I changed back to orginal
prebuilt/$(HOST_PREBUILT_TAG)/toolchain/arm-eabi-4.4.3/bin/arm-eabi-
like gingerbread.
But failed to build whole source:
--------------------------------
frameworks/base/include/binder/IInterface.h:62: error: template with C
linkage
frameworks/base/include/binder/IInterface.h:114: error: template with C
linkage
In file included from frameworks/base/include/ui/Region.h:25,

C linkage
frameworks/base/include/ui/Rect.h:145: error: template specialization with
C linkage

--------------------------------
Any one meet above problem?
