Introduction to elfutils

The elfutils package contains a set of utilities and libraries for handling ELF (Executable and Linkable Format) files.

This package is known to build and work properly using an LFS-8.1 platform.

Package Information

elfutils Dependencies

Optional

Valgrind-3.13.0

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/elfutils

Installation of elfutils

Install elfutils by running the following commands: 

./configure --prefix=/usr --program-prefix="eu-" &&
make

To test the results, issue: make check. One test, run-strip-nothing.sh, is known to fail.

Now, as the root user: 

make install

Command Explanations

--program-prefix="eu-": This switch renames installed programs to avoid conflict with Binutils programs installed in LFS.

--enable-valgrind: Run all tests under valgrind.
