This project is superseded by the CTF support in GNU binutils: it is only used by old versions of its dependent projects. It is still published here in case a bugfix is needed to support one of those projects.
The project has been merged into GNU binutils 2.33 and GCC 12; as of binutils 2.36 it is much more capable and can deduplicate CTF more reliably and rapidly than any other implementation (to my knowledge). Please submit changes to binutils upstream. (Please indicate if you need those changes in an old project that still uses libdtrace-ctf, but all changes should flow in through GNU binutils first.)
libdtrace-ctf is a port of the Solaris Compact Type Format library to Linux. It's meant to be used with DTrace for Linux. Its file format is similar to but not compatible with Solaris CTF files. The public API is source-compatible, to ease adoption of Linux for libctf users.
The source has been available at oss.oracle.com, as a git repository with full git history. By posting the source here on github.com, we hope to increase the visibility for our work and to make it even easier for people to access the source. We will also use this repository to work with developers in the Linux community.
See the dtrace-utils README
for more information on how to build DTrace utilities
with libdtrace-ctf for the Linux kernel.
