Chapter 14. Dyninst
The Dyninst library provides an application programming interface (API) for instrumenting and working with user-space executables during their execution. It can be used to insert code into a running program, change certain subroutine calls, or even remove them from the program. It serves as a valuable debugging and performance-monitoring tool. The Dyninst API is also commonly used along with SystemTap to allow non-
root users to instrument user-space executables.
Red Hat Developer Toolset is distributed with Dyninst 9.1.0.
14.1. Installing Dyninst
In Red Hat Developer Toolset, the Dyninst library is provided by the devtoolset-4-dyninst package and is automatically installed with devtoolset-4-perftools as described in Section 1.5, “Installing Red Hat Developer Toolset”. In addition, it is recommended that you also install the GNU Compiler Collection provided by the devtoolset-4-toolchain package.
If you intend to write a custom instrumentation for binaries, install the relevant header files by running the following command as
root:
yum install devtoolset-4-dyninst-devel
You can also install API documentation for this library by typing the following at a shell prompt as
root:
yum install devtoolset-4-dyninst-doc
For a complete list of documents that are included in the devtoolset-4-dyninst-doc package, see Section 14.3, “Additional Resources”. For detailed instructions on how to install optional packages to your system, see Section 1.5, “Installing Red Hat Developer Toolset”.
Where did the comment section go?
Red Hat's documentation publication system recently went through an upgrade to enable speedier, more mobile-friendly content. We decided to re-evaluate our commenting platform to ensure that it meets your expectations and serves as an optimal feedback mechanism. During this redesign, we invite your input on providing feedback on Red Hat documentation via the discussion platform.
