Method: Elf::File#is_compatible

Defined in:
lib/elf/file.rb

#is_compatible(other) ⇒ Object

Checks whether two ELF files are compatible one with the other for linking

This function has to check whether two ELF files can be linked together (either at build time or at load time), and thus checks for class, encoding, versioning, ABI and machine type.

Note that it explicitly does not check for ELF file type since you can link different type of files together, like an Executable with a Dynamic library.

Raises:

  • (TypeError)
