Bug #: 15430
Summary: objcopy -R makes shared objects unusable
Product: binutils
Version: 2.23
Status: NEW
Severity: normal
Priority: P2
Component: binutils
AssignedTo: unassig...@sourceware.org
ReportedBy: oma...@redhat.com
Classification: Unclassified
Created attachment 7012
--> http://sourceware.org/bugzilla/attachment.cgi?id=7012
readelf -t on the so file before and after running objcopy -R
When I try to remove the build id note from a shared library using "objcopy -R
.note.gnu.build-id lib.so", the library becomes unusable.
$ objdump -T libjvm.so | grep jio_vfprint
00000000005715a0 g DF .text 0000000000000026 SUNWprivate_1.1
jio_vfprintf
$ objcopy -R .note.gnu.build-id libjvm.so
$ objdump -T libjvm.so | grep jio_vfprint
00000000005715a0 g DF .fini 0000000000000026 SUNWprivate_1.1
jio_vfprintf
The function is "moved" from the .text to the .fini section, which makes this
shared object unusable (I get errors when linking this .so).
