"No Such File or Directory" Trying to Execute Linux Binary on Android Device

No such file or directory error when executing a binary

The answer is in this line of the output of readelf -a in the original question

  [Requesting program interpreter: /lib/ld-linux.so.2]

I was missing the /lib/ld-linux.so.2 file, which is needed to run 32-bit apps. The Ubuntu package that has this file is libc6-i386.

How do I run a compiled binary in Android?

Your binary apparently depends on some shared library (.so) that is not visible for dynamic linking. You can use readelf from your toolchain and you get something like this:

tom@pc:~/workspace/test/arm-v7a_android9/release$ ~/toolchains/armeabiv7a_android-9_ndk-r10e_gcc-4.9/bin/arm-linux-androideabi-readelf -d test

Check that all libraries with type (NEEDED) are on your Android device and are visible for your binary (you should use export LD_LIBRARY_PATH=<path>[:<another_path>[..]] to make .so available for dynamic linking with your binary).

If problem isn't still resolved, your application is linked with different version of some system library - try to use an older toolchain.

Android: cannot execute file compiled through Linux Deploy on the same phone

You should compile your binary with gcc '-static' key. If you don't do that, you binary will need dynamic linker ld.so that doesn't exist on Android (but definitely exists inside your chroot!). This implies that strange error message "No such file or directory".

Android shell don't find the file to execute

Your executable is missing a library. The most likely reason is that you just built a Linux ARM executable (not an Android one) which is linked against some libc version other than Android Bionic.

You could either learn how to build proper Android executables or a statically linked binary might just work for your purpose.

Installing a prebuilt binary on Android: not found

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)

No such file or directory while running dalvikvm

I copied the ls program (from bin directory of device) in /opt, it executes fine-

   root@localhost:/opt# file ls  
ls: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux
    2.6.16, BuildID[sha1]=0xd9839725f151e64cfbf15a463e605227938a1619, not stripped

    root@localhost:/opt# ./ls 
    dalvikvm data   dbspace etc ls share usr var

One question is the file command output shows executable in case of ls command, but it shows shared object in case of dalvikvm or any other binary I copy from my AOSP build.

Why is dalvikvm not showing as executable?
