retitle 555549 adding .gnu_debuglink section in kernel modules thanks
Ben,
I looked into dh_strip and it does seem to be doing the right thing.
sub attach_debug {
my $file=shift;
my $debug_path=shift;
doit("objcopy", "--add-gnu-debuglink", $debug_path, $file);
}
attach_debug is called when the -k option is passed.
foreach (@shared_libs) {
my $debug_path = make_debug($_, $tmp, $debugtmp) if
$keep_debug;
# Note that all calls to strip on shared libs
# *must* inclde the --strip-unneeded.
doit("strip","--remove-section=.comment",
"--remove-section=.note","--strip-unneeded",$_);
attach_debug($_, $debug_path) if defined $debug_path;
}
foreach (@executables) {
my $debug_path = make_debug($_, $tmp, $debugtmp) if
$keep_debug;
doit("strip","--remove-section=.comment",
"--remove-section=.note",$_);
attach_debug($_, $debug_path) if defined $debug_path;
}
When -k is specified, $keep_debug is set.
# Support for keeping the debugging symbols in a detached file.
my $keep_debug=$dh{K_FLAG};
And based on $keep_debug, $debug_path is populated
my $debug_path = make_debug($_, $tmp, $debugtmp) if
$keep_debug;
I tried re-building the kernel image with dh_strip -k but that did not help.
So, how is the linux-image-xxxx-dbg package created ?
