https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293536 --- Comment #1 from Martin Cracauer <cracauer@cons.org> --- Truss on kgdb shows that it is not satisfied with finding mac_bsdextended.ko.debug as specified in /var/tmp. It probes OS default places in addition. In my setup it find wrong versions eventually and seems to throw away the .ko.debug that I specified. I don't think it should do that. __realpathat(AT_FDCWD,"/var/tmp/mac_bsdextended.ko.debug","/var/tmp/mac_bsdextended.ko.debug",1024,0) = 0 (0x0) open("/var/tmp/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/lib/debug/var/tmp/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/local/lib/debug/var/tmp/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/xcarb3/usr/local/share/gdb/auto-load/var/tmp/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' __realpathat(AT_FDCWD,"/var/tmp/mac_bsdextended.ko.debug","/var/tmp/mac_bsdextended.ko.debug",1024,0) = 0 (0x0) open("/var/tmp/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/lib/debug/var/tmp/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/local/lib/debug/var/tmp/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/xcarb3/usr/local/share/gdb/auto-load/var/tmp/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' __realpathat(AT_FDCWD,"/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug","/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug",1024,0) = 0 (0x0) open("/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/lib/debug/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/local/lib/debug/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/xcarb3/usr/local/share/gdb/auto-load/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' __realpathat(AT_FDCWD,"/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug","/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug",1024,0) = 0 (0x0) open("/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/lib/debug/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/local/lib/debug/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/xcarb3/usr/local/share/gdb/auto-load/usr/lib/debug/boot/kernel/mac_bsdextended.ko.debug-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' __realpathat(AT_FDCWD,"/boot/kernel/mac_bsdextended.ko","/boot/kernel/mac_bsdextended.ko",1024,0) = 0 (0x0) open("/boot/kernel/mac_bsdextended.ko-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/lib/debug/boot/kernel/mac_bsdextended.ko-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/usr/local/lib/debug/boot/kernel/mac_bsdextended.ko-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' open("/xcarb3/usr/local/share/gdb/auto-load/boot/kernel/mac_bsdextended.ko-gdb.gdb",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' __realpathat(AT_FDCWD,"/boot/kernel/mac_bsdextended.ko","/boot/kernel/mac_bsdextended.ko",1024,0) = 0 (0x0) open("/boot/kernel/mac_bsdextended.ko-gdb.py",O_RDONLY|O_CLOEXEC,0666) ERR#2 'No such file or directory' -- You are receiving this mail because: You are the assignee for the bug.home | help
