Hello everybody. Let's see how we can fix one problem that can happen when you try to compile the Android 2.3 after you already have installed GCC 4.6.

During Android compilation you can receive the following error message:

host Executable: acp (out/host/linux-x86/obj/EXECUTABLES/acp_intermediates/acp)
host SharedLib: libneo_cs (out/host/linux-x86/obj/lib/libneo_cs.so)
host C++: libutils <= frameworks/base/libs/utils/RefBase.cpp
frameworks/base/libs/utils/RefBase.cpp: In member function 'void android::RefBase::weakref_type::trackMe(bool, bool)':
frameworks/base/libs/utils/RefBase.cpp:483:67: error: passing 'const android::RefBase::weakref_impl' as 'this' argument of 'void android::RefBase::weakref_impl::trackMe(bool, bool)' discards qualifiers [-fpermissive]
make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libutils_intermediates/RefBase.o] Error 1
make: *** Waiting for unfinished jobs....

To fix that, open a terminal and run (assuming you are in the folder android):

gedit frameworks/base/libs/utils/Android.mk

Change the line:

LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS)

To:

LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) -fpermissive

After that, save the file and recompile the Android again.

That's it. See you next time.
