Thiago, yes. i will.
PS: now there is a platform/external/gdb.git tree in
http://android.git.linaro.org/gitweb. i would suggest linaro make the
gdb compilable with an Android.mk by arm-eabi-gcc just like other
external components something like:
LOCAL_PATH := $(call my-dir)
LOCAL_MODULE_TAGS := eng
LOCAL_MODULE := gdb
LOCAL_SRC_FILES += \
finally, i hope that will result in a native gdb running on boards and
supporting multithreads. that is actually very useful to many users.
