Я пытаюсь создать исполняемый файл objdump для GT-i9300.
Я получаю следующую ошибку, когда пытаюсь использовать тот, который предоставляется Android NDK, в оболочке adb с помощью su:
root@m0:/data/local/tmp # ./arm-linux-androideabi-objdump
sh: ./arm-linux-androideabi-objdump: not executable: magic 7F45
Согласно этой записи в блоге что ошибки возникают из-за разных архитектур файла и устройства. Итак, мне нужно получить версию objdump для моего устройства:
shell@m0:/ $ uname -a
Linux localhost 3.0.64-CM #1 SMP PREEMPT Fri May 9 09:17:55 CEST 2014 armv7l GNU/Linux
До сих пор я получил arm-linux-androideabi-objdump, скомпилировав его следующим образом на моем Ubuntu 12.10.
someuser@ubuntu1210:~$ uname -a
Linux ubuntu1210 3.11.0-20-generic #35~precise1-Ubuntu SMP Fri May 2 21:32:55 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Я скомпилировал автономный тулчейн, в качестве процессора использовал ARM:

Формат, который я получаю после компиляции:
someuser@ubuntu1210:~/my-android-toolchain/bin$ file arm-linux-androideabi-objdump
arm-linux-androideabi-objdump: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, stripped
Мой вопрос: почему полученный arm-linux-androideabi-objdump компиляции не в нужном формате, чтобы я мог выполнить его из оболочки adb устройства?
