LKBEN11065: Posix error 8: Exec format error


You get the error message: Exec format error




The program you try to run is not an executable format. It is relatively easy to generate this error.

Compile a program with gcc


gcc testprogram -o testprogram

Now you can run the program and nothing is wrong. You can change the compilation like:

gcc testprogram -c -o testprogram

You will notice that what you get is not an executable. If you make it executable with chmod +x testprogram and try to

run it, you will get the error

-bash: ./testprogram: cannot execute binary file
