How to install sigsegv glibc module

Question

I am trying to trap a segmentation fault and the old LD_PRELOAD approach has been deprecated in 2022 (https://www.marcusfolkesson.se/blog/libsegfault/)

I was reading about this new contribution sigsegv and would like to use it. However I am unable to install the library. https://lists.gnu.org/archive/html/bug-gnulib/2021-05/msg00072.html

I am running Fedora and tried sudo dnf install -y libsigsegv-dev to no avail (thanks for nothing ChatGPT :)

Where can I find this library and how do you install it on Fedora? Thanks

There are indeed two options for easily catching SIGSEGV on Unix platforms:

• Use of the Gnulib module sigsegv. The Gnulib documentation describes how to integrate it into the build system of your package.

• Use of libsigsegv as a pre-installed library.

In both cases, #include <sigsegv.h> in your package, and use the function sigsegv_install_handler and/or stackoverflow_install_handler.
