Thanks for the reply. Actually I made a mistake by claiming "dbg packages in ubuntu don't have source code included". Here's a little more information about making sure the binary and dbg package match: $ file /usr/bin/ceph-osd /usr/bin/ceph-osd: ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/l, for GNU/Linux 3.2.0, BuildID[sha1]=8a15177a5cb79533f396ef01e68ba1a2025f07a1, stripped $ ll /usr/lib/debug/.build-id/8a/15177a5cb79533f396ef01e68ba1a2025f07a1.debug -rw-r--r-- 1 root root 195M Mar 26 17:27 /usr/lib/debug/.build-id/8a/15177a5cb79533f396ef01e68ba1a2025f07a1.debug The binary has a "BuildID" field, and gdb would try to find the corresponding debug file under /usr/lib/debug/.build-id Hope it would help, and sorry for the disturbance.
