Issue #17616 has been reported by xtkoba (Tee KOBAYASHI). ---------------------------------------- Feature #17616: Support backtracing on Linux with non-GNU-libc + libunwind https://bugs.ruby-lang.org/issues/17616 * Author: xtkoba (Tee KOBAYASHI) * Status: Open * Priority: Normal ---------------------------------------- Currently, `vm_dump.c` assumes that the availability of `backtrace` implies the existence of `execinfo.h`, but it is not the case with non-GNU libc (e.g. musl or Bionic) Linux systems where libunwind is installed. A patch is attached to enable backtracing on those systems. With this patch, we modify `configure` so that it (1) always checks if `execinfo.h` exists, and that (2) when it cannot find that file on Linux, then checks if `unw_backtrace` is available. In this patch, we assume (in `vm_dump.c`) that on Linux the availability of `unw_backtrace` implies the existence of `libunwind.h`. If it is not the case, a further modification will be needed. It is preferable if we can choose between `backtrace` in glibc or `unw_backtrace` in libunwind when both are available. With this patch, the former is chosen by default, and the latter is chosen when `ac_cv_header_execinfo_h=no` is passed to `configure`. ---Files-------------------------------- ruby-linux-non_glibc-libunwind-backtrace.patch (1.79 KB) -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
