android编译错误及解决方法

1.设置编译选项为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行设置为x86（该步骤可以省略）

3.修改build/tools/dexpreopt目录中Android.mk为Android-arm.mk,不编译该模块(该模块以来与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模块未编译。external/dbus/dbus中mk文件只对TARGET_ARCH = arm时又作用。

4.修改external/dbus/dbus目录中Android.mk,TARGET_ARCH = x86,编译该模块。

system/core/libcutils/memset32.S: Assembler messages:
system/core/libcutils/memset32.S:38: Error: unknown pseudo-op: `.fnstart'

.
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模块在TARGET_SIMULATOR=false时，对arm相关代码有依赖，依赖代码如下：
    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目录中Android.mk中78行(ifneq ($(TARGET_SIMULATOR),true)),暂使用TARGET_SIMULATOR=true编译。

target thumb C: libwpa_client <= external/wpa_supplicant/wpa_ctrl.c
target thumb C: libwpa_client <= external/wpa_supplicant/os_unix.c
cc1: error: unrecognized command line option "-mabi=aapcs-linux"
cc1: error: unrecognized command line option "-mabi=aapcs-linux"

make: *** [out/target/product/generic/obj/SHARED_LIBRARIES/libwpa_client_intermediates/wpa_ctrl.o] Error 1
make: *** Waiting for unfinished jobs....
make: *** [out/target/product/generic/obj/SHARED_LIBRARIES/libwpa_client_intermediates/os_unix.o] Error 1
原因：不识别的命令行选项-mabi=aapcs-linux

6.修改external/wpa_supplicant/目录中Android.mk 20行,去掉-mabi=aapcs-linux选项.

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：定义了HAVE_SYS_SYSLIMITS_H该宏，但无法找到sys/syslimits.h头文件。

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

system/core/debuggerd/crashglue.S:5: Error: no such instruction: `ldr r0,=0xa5a50000'
system/core/debuggerd/crashglue.S:6: Error: no such instruction: `ldr r1,=0xa5a50001'

system/core/debuggerd/crashglue.S:28: Error: no such instruction: `b .'
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模块依赖于arm.

8.修改system/core/debuggerd模块中的Android.mk.重命名为Android-arm.mk,暂不编译该模块。

9.修改bionic/libc/tools目录下的gensyscalls.py,生成x86架构的相关文件。
修改bionic/libc目录下的Android.mk文件，设置为x86.

make: *** 没有规则可以创建“out/target/product/generic/obj/SHARED_LIBRARIES/libc_intermediates/arch-x86/bionic/exidx_dynamic.o”需要的目标“bionic/libc/arch -x86/bionic/exidx_dynamic.c”。停止。
原因：bionic/libc/arch-x86/bionic目录下无exidx_dynamic.c文件。

10.修改bionic/libc/目录中Android.mk文件，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中设置了libc_common_cflags := -D_LIBC=1, 与/usr/include/gnu/stubs-32.h有冲突。

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