android編譯錯誤及解決方案

1.設定編譯選項為make -j5  TARGET_ARCH=x86 TARGET_PRODUCT=generic  TARGET_SIMULATOR=false TARGET_BUILD_TYPE=release TARGET_OS=linux LOCAL_PRELINK_MODULE=false

2.build/core/envsetup.mk 中 91行 設定為x86（該步驟可以省略）

3.修改build/tools/dexpreopt目錄中Android.mk為Android-arm.mk,不編譯該模組(該模組以來與emulator)。

make: *** No rule to make target `out/target/product/generic/obj/lib/libdbus.so', needed by `out/target/product/generic/obj/EXECUTABLES/auth-agent_intermediates/LINKED/auth-agent'.  Stop.
原因：libdbus.so模組未編譯。external/dbus/dbus中mk檔案只對TARGET_ARCH = arm時又作用。

4.修改external/dbus/dbus目錄中Android.mk,TARGET_ARCH = x86,編譯該模組。

system/core/libcutils/memset32.S: Assembler messages:

system/core/libcutils/memset32.S:93: Error: unknown pseudo-op: `.fnend'
make: *** [out/target/product/generic/obj/STATIC_LIBRARIES/libcutils_intermediates/memset32.o] Error 1
原因：system/core/libcutils模組在TARGET_SIMULATOR=false時，對arm相關代碼有依賴，依賴代碼如下：
    LOCAL_SRC_FILES := $(commonSources) memset32.S atomic-android-arm.S mq.c \
                       ashmem-dev.c
    LOCAL_C_INCLUDES := $(KERNEL_HEADERS)

5.修改system/core/libcutils目錄中Android.mk中78行(ifneq ($(TARGET_SIMULATOR),true)),暫使用TARGET_SIMULATOR=true編譯。

make: *** Waiting for unfinished jobs....
make: *** [out/target/product/generic/obj/SHARED_LIBRARIES/libwpa_client_intermediates/os_unix.o] Error 1
原因：不識別的命令列選項-mabi=aapcs-linux

6.修改external/wpa_supplicant/目錄中Android.mk 20行,去掉-mabi=aapcs-linux選項.

external/dbus/dbus/dbus-sysdeps-util-unix.c:48:27: error: sys/syslimits.h: No such file or directory
make: *** [out/target/product/generic/obj/SHARED_LIBRARIES/libdbus_intermediates/dbus-sysdeps-util-unix.o] Error 1
原因：定義了HAVE_SYS_SYSLIMITS_H該宏，但無法找到sys/syslimits.h標頭檔。

7.修改external/dbus/config.h中197行，#undef HAVE_SYS_SYSLIMITS_H。

target arm C: libc <= bionic/libc/bionic/malloc_leak.c
make: *** [out/target/product/generic/obj/EXECUTABLES/crasher_intermediates/crashglue.o] Error 1
原因：system/core/debuggerd模組依賴於arm.

8.修改system/core/debuggerd模組中的Android.mk.重新命名為Android-arm.mk,暫不編譯該模組。

9.修改bionic/libc/tools目錄下的gensyscalls.py,產生x86架構的相關檔案。
  修改bionic/libc目錄下的Android.mk檔案，設定為x86.

 make: *** 沒有規則可以建立“out/target/product/generic/obj/SHARED_LIBRARIES/libc_intermediates/arch-x86/bionic/exidx_dynamic.o”需要的目標“bionic/libc/arch    -x86/bionic/exidx_dynamic.c”。 停止。
原因：bionic/libc/arch-x86/bionic目錄下無exidx_dynamic.c檔案。

10.修改bionic/libc/目錄中Android.mk檔案，去掉“arch-x86/bionic/exidx_dynamic.c \”。

make: *** [out/target/product/generic/obj/SHARED_LIBRARIES/libc_intermediates/bionic/malloc_leak.o] Error 1
原因：bionic/libc/Android.mk中設定了libc_common_cflags := -D_LIBC=1, 與/usr/include/gnu/stubs-32.h有衝突。

11.修改bionic/libc/Android.mk,去掉libc_common_cflags中 -d_LIBC=1.
