Hi Jean, Seems you already got your answer to the build question solved.

Note that there is some code in elfutils git that handles .debug_frame for ARM, but not yet code for handling EXIDX tables. For non-debug unwinding ARM uses EXIDX tables, not .eh_frames. Handling EXIDX tables is probably easiest done by translating them to CFI. In case you want to do unwinding using libdw without .debug_frame available. For AARCH64 there is some code available on my branch: https://git.fedorahosted.org/cgit/elfutils.git/log/?h=mjw/aarch64-unwind Which might or might not work. I need to get access again to a aarch64 setup to do some more testing before moving this to master. Cheers, Mark
