Chapter 5. elfutils elfutils is a collection of various binary tools, such as eu-objdump , eu-readelf , and other utilities that allow you to inspect and manipulate ELF files. See Table 5.1, "Tools Included in elfutils for Red Hat Developer Toolset" for a complete list of binary tools that are distributed with the Red Hat Developer Toolset version of elfutils . Red Hat Developer Toolset is distributed with elfutils 0.187 . This version is more recent than the version included the release of Red Hat Developer Toolset and provides some bug fixes and enhancements. Table 5.1. Tools Included in elfutils for Red Hat Developer Toolset Name Description eu-addr2line Translates addresses into file names and line numbers. eu-ar Creates, modifies, and extracts files from archives. eu-elfcmp Compares relevant parts of two ELF files for equality. eu-elflint Verifies that ELF files are compliant with the generic ABI ( gABI ) and processor-specific supplement ABI ( psABI ) specification. eu-findtextrel Locates the source of text relocations in files. eu-make-debug-archive Creates an offline archive for debugging. eu-nm Lists symbols from object files. eu-objdump Displays information from object files. eu-ranlib Generates an index to the contents of an archive to make access to this archive faster. eu-readelf Displays information about ELF files. eu-size Lists section sizes of object or archive files. eu-stack A new utility for unwinding processes and cores. eu-strings Displays printable character sequences in files. eu-strip Discards all symbols from object files. eu-unstrip Combines stripped files with separate symbols and debug information. 5.1. Installing elfutils In Red Hat Developer Toolset, elfutils is provided by the devtoolset-12-elfutils package and is automatically installed with devtoolset-12-toolchain as described in Section 1.5, "Installing Red Hat Developer Toolset" . 5.2. Using elfutils To execute any of the tools that are part of elfutils , run the tool as follows: See Table 5.1, "Tools Included in elfutils for Red Hat Developer Toolset" for a list of tools that are distributed with elfutils . For example, to use the eu-objdump tool to inspect an object file: Note that you can execute any command using the scl utility, causing it to be run with the Red Hat Developer Toolset binaries used in preference to the Red Hat Enterprise Linux system equivalent. This allows you to run a shell session with Red Hat Developer Toolset binary tools as default: Note To verify the version of elfutils you are using at any point: Red Hat Developer Toolset's eu-objdump executable path will begin with /opt . Alternatively, you can use the following command to confirm that the version number matches that for Red Hat Developer Toolset eu-objdump : 5.3.
