I'm trying to get callstacks out of a core file using libdwfl where the ELF files live in a sysroot (and are from a different architecture, ARM).
I'm possibly doing something stupid as I find that dwfl_link_map_report() opens /lib/libpthread.so on the *host* rather than the libpthread.so from my sysroot. It obviously doesn't then get very far. I called elf_begin(), dwfl_begin() and then dwfl_core_file_report(), passing in the path to the executable (in the sysroot). There's a comment in link_map.c around line 390 which says: // XXX hook for sysroot So inspired by this, I hacked in some code to open files relative to my sysroot and it all started working. Am I just missing some obvious setup, or is this just missing sysroot support? Thanks! Luke
