Description abhijit karmarkar 2004-03-16 05:38:41 UTC 
Description of problem: 
objdump -g <objectfile> does not print debugging info.

Version-Release number of selected component (if applicable):
RHEL3 AS, Update 1.

How reproducible:
Always.

Steps to Reproduce:
1. compile any C program with "-g" (gcc -g -o foo foo.c)
2. try dumping debugging info: objdump -g foo
  
Actual results:
objdump: foo: no recognized debugging information

Expected results:
objdump should print debugging (stabs) info.
i am especially interested in struct info (size, member offsets etc.)

looks that gcc3 does not have a .stabs ELF section. and that
makes objdump believe that there is no debugging information.

Additional info:
this happens with gcc 3.2 and binutils w/ RHEL3 Update 1.
gcc version: gcc (GCC) 3.2.3 20030502 (Red Hat Linux 3.2.3-24)
binutils   : 2.14.90.0.4-26.3
objdump ver: GNU objdump 2.14.90.0.4 20030523
Comment 1 Jakub Jelinek 2004-03-16 11:41:28 UTC 
Please read the manual page of objdump:
"-g ... Only certain types of debugging information have been
implemented.  Some other types are supported by `readelf -w'."

Particularly, DWARF2 which now GCC emits by default is supported
only by readelf -w[liaprmfFso].
