To execute a binary or  run file in Linux from the shell  use the dot forward slash friend     binary file name   and if it fails say because of permissions  you could try this before executing it   chmod  x binary file name    then execute it    binary file name   Hope it helps

To execute a binary  use    binary name   If you get an error       bash    binary name  cannot execute binary file   it ll be because it was compiled using a tool chain that was for a different target to that which you re attempting to run the binary on   For example  if you compile  binary name c  with arm-none-linux-gnueabi-gcc and try run the generated binary on an x86 machine  you will get the aforementioned error

your compilation option -c makes your compiling just compilation and assembly  but no link

full path for binary file  For example   home vitaliy2034 binary file name  Or use directive     binary file name        in unix system it return full path to directory  in which you open terminal shell   I hope it helps  Sorry  for my english language

-  If not typo  why are you using   commonRT  instead of   commonKT

The only way that works for me  extracted from here     chmod a x name of file bin   Then run it by writing    name of file bin   If you get a permission error you might have to launch your application with root privileges    sudo   name of file bin

It is possible that you compiled your binary with incompatible architecture settings on your build host vs  your execution host  Can you please have a look at the enabled target settings via  g    all-your-build-flags-here  -Q -v --help target   on your build host  In particular  the COLLECT GCC OPTIONS variable may give you valuable debug info  Then have a look at the CPU capabilities on your execution host via  cat  proc cpuinfo   grep -m1 flags   Look out for mismatches such as -msse4 2  enabled  on your build host but a missing sse4 2 flag in the CPU capabilities   If that doesn t help  please provide the output of ldd commonKT on both build and execution host

This is an answer to  craq       I just compiled the file from C source and set it to be executable with chmod  There were no warning or error messages from gcc    I m a bit surprised that you had to  set it to executable  -- my gcc always sets the executable flag itself  This suggests to me that gcc didn t expect this to be the final executable file  or that it didn t expect it to be executable on this system   Now I ve tried to just create the object file  like so     gcc -c -o hello hello c   chmod  x hello    hello c is a typical  Hello World  program   But my error message is a bit different       hello bash    hello  cannot execute binary file  Exec format error    On the other hand  this way  the output of the file command is identical to yours     file hello hello  ELF 64-bit LSB  relocatable  x86-64  version 1  SYSV   not stripped   Whereas if I compile correctly  its output is much longer     gcc -o hello hello c   file hello hello  ELF 64-bit LSB  executable  x86-64  version 1  SYSV   dynamically linked  uses shared libs   for GNU Linux 2 6 24  BuildID sha1  131bb123a67dd3089d23d5aaaa65a79c4c6a0ef7  not stripped   What I am saying is  I suspect it has something to do with the way you compile and link your code  Maybe you can shed some light on how you do that

The volume it s on is mounted noexec

Or  the file is of a filetype and or architecture that you just cannot run with your hardware and or there is also no fallback binfmt misc entry to handle the particular format in some other way  Use file 1  to determine

If it is not a typo  as pointed out earlier  it could be wrong compiler options like compiling 64 bit under 32 bit  It must not be a toolchain
