我在我的linux机器上使用GDB可执行文件来调试我的可执行文件（rild）。
rild: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked (uses shared libs), BuildID[md5/uuid]=d100d90599eb3764018356c9ef3e1840, not stripped
然而，当我运行命令
时./arm-linux-androideabi-gdb ~/android_gdb/system_bin/rild
GNU gdb (GDB) 7.6

This GDB was configured as "--host=x86_64-linux-gnu --target=arm-linux-android".

"/home/user/android_gdb/system_bin/rild": not in executable format: File format not recognized
我可以看到GDB也是64位版本，可执行ELF也是未剥离的，64位。但它还是不起作用。
答案 0 :(得分：1)
rild: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV),
这是一个aarch64 64位ARM二进制文件。
This GDB was configured as "--host=x86_64-linux-gnu --target=arm-linux-android"
此GDB是一个64位x86_64二进制文件，配置为调试32位ARM二进制文件。
GDB本身是一个64位二进制文件的事实是无关紧要的。重要的是它被配置为调试的目标。您需要使用--target=aarch64-linux-android配置的其他GDB。
