When I attempt to use: # which kgdb /usr/local/bin/kgdb that was from building devel/gdb for: # svnlite info /usr/ports | grep "Re[plv]" Relative URL: ^/head Repository Root: https://svn.freebsd.org/ports Repository UUID: 35697150-7ecd-e111-bb59-0022644237b5 Revision: 440115 Last Changed Rev: 440115 (built via gcc 4.2.1: not via clang: I experiment with clang for powerpc and powerpc64 so I'm being explicit) I end up getting the following sort of result: # kgdb /usr/lib/debug/boot/kernel/kernel.debug /var/crash/vmcore.4 . . . Reading symbols from /usr/lib/debug/boot/kernel/kernel.debug...done. ABI doesn't support a vmcore target That message is from: /usr/ports/devel/gdb/files/kgdb/fbsd-kvm.c . . . static void kgdb_trgt_open(const char *arg, int from_tty) { struct fbsd_vmcore_ops *ops = (struct fbsd_vmcore_ops *) gdbarch_data (target_gdbarch(), fbsd_vmcore_data); . . . if (ops == NULL || ops->supply_pcb == NULL || ops->cpu_pcb_addr == NULL) error ("ABI doesn't support a vmcore target"); . . . It appears that there is no kernel debugging supported for TARGET_ARCH=powerpc currently. (The system no longer has its own gdb related materials.) === Mark Millard markmi at dsl-only.net _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
