Description Karel Klíč 2011-08-08 15:18:57 UTC

A problem related to debuginfo was found in the nfs-utils-lib-1.1.5-3.el6 package. This issue might affect crash analysis done by Automatic Bug Reporting Tool and its retrace server, and also prevent proper debugging of crashes via GDB.

When a binary is compiled without gcc's -g option, no debugging information is generated and rpmbuild creates almost-empty debuginfo file, which cannot be used for debugging. Please fix the package build process to use $RPM_OPT_FLAGS, which include the -g option among others.

path: /usr/lib/debug/usr/lib/libnfsidmap/umich_ldap.so.debug
package: nfs-utils-lib-debuginfo-1.1.5-3.el6.i686

This issue can be investigated and tested by using eu-readelf tool from the elfutils package. Use `eu-readelf --section-headers /usr/lib/debug/usr/bin/<debuginfofile>.debug` to see if debuginfo file contains .debug_info section. It is supposed to be there.

(This bug was detected and filed by a script.)

Comment 5 RHEL Product and Program Management 2012-09-07 05:08:22 UTC

This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.

I'm not understanding what the problem is here or how to fix it... Can you be a bit more explicit as to what you are asking for?

Comment 7 Karel Klíč 2012-10-15 08:54:47 UTC

Hi Steve,

/usr/lib/debug/usr/lib/libnfsidmap/umich_ldap.so.debug is supposed to contain debugging symbols for umich_ldap.so shared library, but it doesn't contain them.

This is usually caused by a missing compiler/linker flag -g during the package build.

Is nfs-utils-lib build with -g?

Ideally, $RPM_OPT_FLAGS, which includes -g, are added to the compiler flags.

Comment 8 Steve Dickson 2012-10-15 20:51:08 UTC

So something like this:

diff --git a/nfs-utils-lib.spec b/nfs-utils-lib.spec
index fa152a5..7c06576 100644
--- a/nfs-utils-lib.spec
