使用 QEMU 在 x86_64 Ubuntu 上模擬 AARCH64 二進制呼叫 libgps 會給出“錯誤重定位：找不到符號”錯誤
這與此處和此處發布的問題類似。我想對一個名為gpslogger的二進製文件進行逆向工程，但在使用 GDB 調試它之前，我希望使用 QEMU (qemu-aarch64) 簡單地模擬它，因為當我執行時
file gpslogger我得到gpslogger: ELF 64-bit LSB executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-aarch64.so.1, not stripped. 我首先下載確切的解釋器文件並將其粘貼到我的 Ubuntu 16.04 x86_64/lib文件夾中，然後出現其他錯誤，要求其他.so文件，例如libgps.so..so然後我為 AARCH64 架構下載這些文件並將它們粘貼到/lib我的 Ubuntu 的文件夾中。一旦所有.so錯誤，即no such file or directory消失，我就剩下Error relocating /lib/libgps.so: __strdup: symbol not found Error relocating /lib/libgps.so: __fdelt_chk: symbol not found Error relocating /lib/libgps.so: __fprintf_chk: symbol not found Error relocating /lib/libgps.so: __snprintf_chk: symbol not found Error relocating /lib/libgps.so: __isnan: symbol not found Error relocating /lib/libgps.so: __syslog_chk: symbol not found Error relocating /lib/libgps.so: __vsnprintf_chk: symbol not found Error relocating /lib/libdbus-1.so.3: __snprintf_chk: symbol not found Error relocating /lib/libdbus-1.so.3: __vsnprintf_chk: symbol not found Error relocating /lib/libdbus-1.so.3: __strncpy_chk: symbol not found Error relocating /lib/libdbus-1.so.3: __vfprintf_chk: symbol not found Error relocating /lib/libdbus-1.so.3: __fprintf_chk: symbol not found Error relocating /lib/libdbus-1.so.3: __vsprintf_chk: symbol not found Error relocating /lib/libsystemd.so.0: __sprintf_chk: symbol not found Error relocating /lib/libsystemd.so.0: reallocarray: symbol not found Error relocating /lib/libsystemd.so.0: __register_atfork: symbol not found Error relocating /lib/libsystemd.so.0: __memcpy_chk: symbol not found Error relocating /lib/libsystemd.so.0: __snprintf_chk: symbol not found Error relocating /lib/libsystemd.so.0: __vsnprintf_chk: symbol not found Error relocating /lib/libsystemd.so.0: __strncpy_chk: symbol not found Error relocating /lib/libsystemd.so.0: __vasprintf_chk: symbol not found Error relocating /lib/libsystemd.so.0: __open64_2: symbol not found Error relocating /lib/libsystemd.so.0: __asprintf_chk: symbol not found Error relocating /lib/libsystemd.so.0: __fprintf_chk: symbol not found Error relocating /lib/libsystemd.so.0: __ppoll_chk: symbol not found Error relocating /lib/libsystemd.so.0: fcntl64: symbol not found Error relocating /lib/libsystemd.so.0: __explicit_bzero_chk: symbol not found Error relocating /lib/libsystemd.so.0: parse_printf_format: symbol not found Error relocating /lib/libsystemd.so.0: __openat64_2: symbol not found Error relocating /lib/libgcrypt.so.20: __memcpy_chk: symbol not found Error relocating /lib/libgcrypt.so.20: __snprintf_chk: symbol not found Error relocating /lib/libgcrypt.so.20: __fdelt_chk: symbol not found Error relocating /lib/libgcrypt.so.20: __vfprintf_chk: symbol not found Error relocating /lib/libgcrypt.so.20: __memset_chk: symbol not found Error relocating /lib/libgcrypt.so.20: __fprintf_chk: symbol not found Error relocating /lib/libgcrypt.so.20: __read_chk: symbol not found Error relocating /lib/libgcrypt.so.20: __syslog_chk: symbol not found Error relocating /lib/libgpg-error.so.0: __sprintf_chk: symbol not found Error relocating /lib/libgpg-error.so.0: __fdelt_chk: symbol not found Error relocating /lib/libgpg-error.so.0: __vfprintf_chk: symbol not found Error relocating /lib/libgpg-error.so.0: __memset_chk: symbol not found Error relocating /lib/libgpg-error.so.0: __fprintf_chk: symbol not found Error relocating gpslogger: GPSNMEA: symbol not found除了最後一個重定位錯誤，我相信所有其他功能都應該在
glibc. 因此，我只是libc-2.32.so從這裡下載了 AARCH64 架構的文件並將其粘貼到/lib我的 Ubuntu 的文件夾中。然而，錯誤並沒有消失。如果需要更多資訊，請告訴我。我很感激在這個問題上的任何幫助。編輯：
readelf -d gpslogger | grep 'NEEDED'返回：
0x0000000000000001 (NEEDED) Shared library: [libgps.so]
0x0000000000000001 (NEEDED) Shared library: [libc.musl-aarch64.so.1]這是否意味著
libc來自musl而不是glibc？
的輸出中的“interpreter
/lib/ld-musl-aarch64.so.1”file表明它gpslogger是用 musl 建構的。這意味著您不僅需要 musl 動態連結器 (ld-musl-aarch64.so.1)，而且還需要 musl 使用的每個庫的 musl 變體gpslogger。您列出的缺失符號表明您安裝的庫是為 glibc 建構的。
