What is an “exec format error”?

An “exec format error” is a type of error that can occur when you try to execute a file that is not in the correct format for your system. This can happen if you try to execute a binary file that is not intended for your architecture, or if you try to execute a script that is not in the correct format.

What causes an “exec format error”?


An “exec format error” is caused by an attempt to run a file that is not recognized by the operating system as a program.

The vast majority of the time, this is because the file is not actually a program, but is instead a data file. For example, a Word document or an image file cannot be run as a program and will cause an “exec format error” if you try to do so.

In some cases, however, the file may actually be a valid program but one that is not compatible with your operating system. For example, Windows cannot run programs written for Linux/Unix systems (and vice versa). If you try to run such a program, you will get an “exec format error.”

How to fix an “exec format error”


If you are getting an “exec format error” while trying to run a program, it means that the program is not in a format that your computer can understand. To fix this, you need to recompile the program so that it is in a format that your computer can understand.

There are two ways to do this:

  1. Use a compiler that can output programs in a format that your computer can understand. For example, if you are using GCC, you can use the “-o” option to output programs in the ELF format.
  2. Use a cross-compiler. A cross-compiler is a compiler that runs on one platform (e.g. Windows) and produces programs for another platform (e.g. Linux).
