HP-UX Reference (11i v2 03/08) - 1 User Commands A-M (vol 1)

l
ld(1) ld(1)
-x Strip local symbols from the output file. This reduces the size of the output file
without impairing the effectiveness of object file utilities. This option is incompati-
ble with the -r option and the +ild
options. (The incremental linker requires the
parts of the output load module which are stripped out with the
-x option.)
Note: Use of the
-x option might impair or prevent the use of a symbolic debugger
on the resulting program.
-y symbol Indicate each file in which symbol appears. You can specify more than one symbol
on the command line with multiple option-symbol pairs, that is, each symbol you
specify must be preceded by the
-y option.
-z Arrange for run-time dereferencing of null pointers to produce a
SIGSEGV signal.
(This is the complement of the
-Z option.
-Z is the default.)
-A name This option is ignored and generates a warning message.
-B bind Select run-time binding behavior of a program using shared libraries or the binding
preference in building a shared library. The most common values for bind are:
direct
Create direct link between symbol references and shared libraries by record-
ing the name of the resolved shared libray during symbol resolution. This
information is used during runtime to quickly resolve symbols without search-
ing through all currently loaded libraries.
-B direct will implicitly turn on symbolic binding (see -B symbolic) and
disable dependent shared library processing.
Direct binding can be disable during runtime by setting the
LD_NODIRECTBIND environment variable.
deferred
Bind addresses on first reference rather than at program start-up time. This is
the default.
group
Mark the shared library so that it behaves as if loaded with RTLD_GROUP flag
to dlopen(). This does not affect the dependent shared libraries.
immediate
Bind addresses of all symbols immediately upon loading the library. Com-
monly followed by -B nonfatal to allow procedure calls that cannot be
resolved at program start-up to be resolved on first reference.
Since
-B nonfatal suppresses messages about unresolved symbols, also
specify -B verbose to display those messages.
See the example below.
lazydirect
Only record direct bind information to shared libraries marked for lazy load-
ing. See +[no]lazyload.
nodelete
Mark the shared library so that an explicit unload using dlclose() or
shl_load() returns success silently without detaching the shared library
from the process. Subsequently, the shared library handle is valid only for
shl_findsym(). It stays invalid for dlsym(), dlclose(), and
shl_unload() until the next explicit load using shl_load() or dlo-
pen().
nodirect
Disallow direct binding. Only a "direct hint" is recorded for references to
libraries marked for lazy loading. This is the default behavior.
nonfatal
If also using -B immediate, for code symbols that could not be bound at
program startup, defer binding them until they are referenced. See descrip-
tion of -B immediate above.
