Android compilation errors and Solutions

1. Set the compilation option to make-J5 target_arch = x86 target_product = generic target_simulator = false target_build_type = release target_ OS = Linux local_prelink_module = false.

2. Set line 91 in build/CORE/envsetup. mk to x86 (this step can be omitted)

3. Modify Android. mk In the build/tools/dexpreopt directory as a Android-arm.mk and do not compile the module (this module since with emulator ).

Make: *** no rule to make target 'out/target/product/generic/obj/lib/libruntime. so ', needed by 'out/target/product/generic/obj/executables/auth-agent_intermediates/linked/auth-agent '. stop.
Cause: the libbench. So module is not compiled. The MK file in external/examples only applies to target_arch = arm.

4. Modify Android. mk, target_arch = x86 in the external/targets/templates directory to compile the module.

System/CORE/libcutils/memset32.s: receiver 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
Cause: the system/CORE/libcutils module depends on ARM-related code when target_simulator = false. The dependent code is as follows:
Local_src_files: = $ (commonsources) memset32.s atomic-android-arm.S MQ. c \
Ashmem-dev.c
Local_c_includes: = $ (kernel_headers)

5. Modify 78 rows of Android. mk in the system/CORE/libcutils directory (ifneq ($ (target_simulator), true). Currently, target_simulator = true is used for compilation.

Target thumb C: libwpa_client <= external/wpa_supplicant/wpa_ctrl.c
Target thumb C: libwpa_client <= external/wpa_supplicant/OS _unix.c
C0: Error: Unrecognized command line option "-mabi = aapcs-Linux"
C0: Error: Unrecognized command line option "-mabi = aapcs-Linux"
Target thumb C: libnetutils <= system/CORE/libnetutils/dhcpclient. c
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
Cause: Unknown command line options-mabi = aapcs-Linux

6. Modify the Android. mk 20 lines in the external/wpa_supplicant/directory and remove the-mabi = aapcs-Linux option.

External/users/connectors/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
Cause: the macro have_sys_syslimits_h is defined, but the header file SYS/syslimits. h cannot be found.

7. Modify row 197 in external/users/config. H, # 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
Cause: the system/CORE/debugadh module depends on arm.

8. Modify Android. mk. In the system/CORE/debugadh module to rename it as a Android-arm.mk and do not compile the module for the moment.

9. Modify gensyscils. py in the bionic/libc/tools directory to generate files related to the X86 architecture.
Modify the Android. mk file in the bionic/libc directory to x86.

Make: * ** no rules are available to create the target "Bionic/libc/arch-x86/" required by "out/target/product/generic/obj/shared_libraries/libc_intermediates/arch-x86/bionic/exidx_dynamic.o/ bionic/exidx_dynamic.c ". Stop.
Cause: There is no exidx_dynamic.c file under the bionic/libc/arch-x86/bionic directory.

10. Modify the Android. mk file in the bionic/libc/directory and remove "arch-x86/bionic/exidx_dynamic.c \".

Make: *** [out/target/product/generic/obj/shared_libraries/libc_intermediates/bionic/malloc_leak.o] Error 1
Cause: libc_common_cflags: =-d_libc = 1 is set in Bionic/libc/Android. mk, which is in conflict with/usr/include/GNU/stubs-32.h.

11. Modify bionic/libc/Android. mk and remove-d_libc = 1 from libc_common_cflags.
