I’m trying to install a prebuilt binary in a custom Android image. For that

  • 0

I’m trying to install a prebuilt binary in a custom Android image. For that I have copied it to a new directory in prebuilt/android-arm/ with an Android.mk file similar to this one:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_SRC_FILES := binary_name
LOCAL_MODULE := binary_name
LOCAL_MODULE_CLASS := EXECUTABLES
include $(BUILD_PREBUILT)

So if I run make system_image binary_name, the binary file is copied to /bin/ in system image. And if I run the emulator I can see the binary file in /system/bin. The permissions are the same as the other executables (-rwxr-xr-x) and, according to file, this is an ARM binary (ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), stripped).

But when I run it on the emulator, it says:

# binary_name
binary_name: not found

I have straced it and this is what I can see:

# strace binary_name
execve("/system/bin/binary_name", ["binary_name"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)
write(2, "strace: exec", 12strace: exec)            = 12
write(2, ": ", 2: )                       = 2
write(2, "No such file or directory", 25No such file or directory) = 25
write(2, "\n", 1
)                       = 1
io_submit(1, -1344063348, {...} <unfinished ... exit status 1>

But the file is there, and strace is able to find it.

Any idea of what can be happening?

UPDATE: As Kristof says, this is probably a problem of dynamic linking, but I don’t have ldd for Android ARM…

    Perhaps some of the required dynamic libraries can’t be found.

    Try ‘ldd binary_name’

    The output should look a little like this if all libraries can be found.
    Missing libraries should be clearly marked.

    linux-gate.so.1 =>  (0xb7fbf000)
libcap.so.2 => /lib/libcap.so.2 (0xb7fa7000)
libdl.so.2 => /lib/i686/cmov/libdl.so.2 (0xb7fa3000)
libncursesw.so.5 => /lib/libncursesw.so.5 (0xb7f64000)
libm.so.6 => /lib/i686/cmov/libm.so.6 (0xb7f3e000)
libc.so.6 => /lib/i686/cmov/libc.so.6 (0xb7dde000)
libattr.so.1 => /lib/libattr.so.1 (0xb7dd9000)
/lib/ld-linux.so.2 (0xb7fc0000)
