+e symbol When building a shared library or program, mark the symbol for export to the
dynamic loader. Only symbols explicitly marked are exported. When building a
shared library, calls to symbols that are not exported are resolved internally.
+ee symbol This option is similar to the
+e option in that it exports a symbol. However, unlike
the
+e option, +ee does not alter the visibility of any other symbol in the file. In a
32-bit link or +compat mode 64-bit link, it has the effect of exporting the specified
symbol without hiding any of the symbols exported by default. In a 64
+std link, all
symbols are exported by default, so
+ee
is not necessary to make a symbol visible.
However, it has the additional side effect of identifying the symbol as necessary, so
that it will not be removed when using dead code elimination (
+Oprocelim ). Of
course,
+ee still retains its export behavior if an option such as
+hideallsymbols
is also given.
+fb Instructs the linker to run the fastbind tool on the executable it has produced. The
executable should be linked with shared libraries. For more details refer to fast-
bind(1), the
+help option, or the HP-UX Linker and Libraries User’s Guide manual.
This option is incompatible with the
+ild option.
+fbu Pass the -u option to the fastbind tool. For more details refer to fastbind(1), the
+help option, or the HP-UX Linker and Libraries User’s Guide manual. This option
is incompatible with the
+ild option.
+filter shared_library_path
Enables the shared library filter mechanism, which allows you divide a large library
into a "filter" and several "implementation" libraries for more efficient organization of
shared libraries. shared_library_path specifies the location of the filter library. See
the HP-UX Linker and Libraries User’s Guide for more information.
+fini function_name
Specify the terminator (finalizer) functions to be invoked in forward order, the order
the functions appear left to right on the command line. The terminator functions are
called in reverse of the depth-first order of initializers.
Use this option while building a shared library, an incomplete executable, or fully
bound executable. Functions specified with this option should take no arguments and
return nothing (void functions). Terminators are invoked only if
main() calls
exit(). They are not called if main() calls return().
Do not use +fini with the -r option. (The linker ignores the +fini option.)
You can specify more than one terminator function on the command line with multiple
option-symbol pairs, that is, each function you specify must be preceded by the
+fini option.
For more details on the terminator function, use the +help option or see the HP-UX
Linker and Libraries User’s Guide.
+gst Enable the global symbol table hash mechanism, used to look up values of symbol
import/export entries. The +gst and related options provide performance enhance-
ments through use of global symbol table which improves searching for exported sym-
bols. See dld.sl(5) and the HP-UX Linker and Libraries Online User Guide for more
information.
+gstsize size
Request a particular hash array size using the global symbol table hash mechanism.
The default value is 1103. The value can be overridden at runtime by setting the
_HP_DLDOPTS environment variable to the value -symtab_size prime number.
You can set the value using chatr +gstsize size file.
+h internal_name
When building a shared library, record internal_name as the name of the library.
When the library is used to link another executable file (program or shared library),
this internal_name is recorded in the library list of the resulting output file instead of
the file system pathname of the input shared library.
That is, if +h is not used, the shared library does not have an internal name and when
an executable is built with the shared library, the linker records the library name that
it looks at.
