I want to generate System.map from vmlinuz,cause most of machines don't have the file System.map.In fact,vmlinuz are compressed to vmlinuz or bzImage.

It's any tool or script can do this?

I tried:

dd if=/boot/vmlinuz skip=`grep -a -b -o -m 1 -e $'\x1f\x8b\x08\x00' /boot/vmlinuz | cut -d: -f 1` bs=1 | zcat > /tmp/vmlinux

It was failed:

zcat: stdin: not in gzip format
32769+0 records in
32768+0 records out
bash linux-kernel kernel
