It was initially developed for GCC and only available in the GCC tree. Ian Lance Taylor is a GCC developer. However, my point is that libbacktrace does not install as a .so shared library. Try to find packages for debian, rhel, ... It's just not distributed. As there is a standalone github repo now, the DMD builds could probably compile the source code into libdruntime like GCC does, but it's not as simple as linking a library. -- Johannes
