Hi, I have written a kernel module which I build using: Makefile (edited a bit) ========== obj-m := simple.o simple-objs := s.o make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules ======= Everything builds fine. But my kernel module caused an oops and the message was something like: myfunctionname +0x2507 +5679 or some hexadecimal gibberish. I know that I can use some external tool to find out what these addresses mean. But, is there a way I can get the kernel oops message to print these information along with line number ? Is there a way to build the kernel module with debug symbols ? In user space, I usually do "-g" or "-ggdb" and it will give me line numbers and filenames neatly while dumping stacktrace. Is there a similar facility available for out of tree kernel modules too ? Even if I give : $ CFLAGS="-ggdb" make The output file size (.ko) is not changed. Can someone help me with building kernel modules with debug info and get the filename and line numbers printed in the oops messages / coredump ? Thanks. -- Sankar P http://psankar.blogspot.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
