Jo-Philipp Wich	12b122f31f	ld.so: ldd crashes when __LDSO_SEARCH_INTERP_PATH__ is not #defined Since b65c7b2c79debcb9017e31913e01eeaa280106fb, the implicit search path can be disabled by not #defining __LDSO_SEARCH_INTERP_PATH__. This causes _dl_ldsopath to never be set, so it remains NULL. _dl_ldsopath is still used when __LDSO_LDD_SUPPORT__ is #defined, to strip the path off of the beginning of the absolute path to the ld.so interpreter in use for printing. The _dl_strlen will crash with a NULL argument. Rather than relying on _dl_ldsopath, this change causes ldd to compute the interpreter's basename directly. glibc ld.so seems to print the full path to the interpreter without any computed basename or =>. I personally prefer glibc's behavior, but to preserve backwards compatibility with uClibc ld.so, the existing format with the computed basename, =>, and full path is used here. This enables simpler (and unchanged) text processing in a pipeline. Signed-off-by: Mark Mentovai <mark at moxienet.com> SVN-Revision: 23892	2010-11-05 21:38:38 +00:00
