I might miss here something obvious. I’m trying to understand why there is no libbacktrace available as an rpm package? Now it seems that it’s bundled with gcc
$ grep libbacktrace gcc.spec
Provides: bundled(libbacktrace)
but neither backtrace.h nor the libbacktrace.a library seem to be available to other projects.
I guess it’s for gcc - internal use only?
Then the question remains, would it make sense to package libbacktrace?
I suspect you would need to ask the gcc packager about this.
I know they read the fedora devel mailing list, you could post a question there.
Or you could raise a bug asking for the .h and .a and see what they say.
THere has been a lot of work on reliable backtrace reporting recently.
I wonder if libbacktrace is still what you need to use on Fedora.
But that is not something I kno enough about to be helpful.
You will need the guidance of the GCC packages.
