dynamic library mentioned on the
command line, regardless of whether the library is actually needed or not. --as-needed causes a DT_NEEDED tag to only be emitted for a library that at that point in the link satisfies a non‐weak undefined symbol
reference from a regular object file or, if the library is not found in the DT_NEEDED lists of other needed libraries, a non‐weak undefined symbol reference from another needed dynamic library. Object files or
libraries appearing on the command line after the library in question do not affect whether the library is seen as needed. This is similar to the rules for extraction of object files from archives.
--no-as-needed restores the default behaviour.
Note: On Linux based systems the --as-needed option also has an affect on the behaviour of the --rpath and --rpath-link options. See the description of --rpath-link for more details.
--add-needed
--no-add-needed
These two options have been deprecated because of the similarity of their names to the --as-needed and --no-as-needed options. They have been replaced by --copy-dt-needed-entries and --no-copy-dt-needed-entries.
-assert keyword
This option is ignored for SunOS compatibility.
-Bdynamic
-dy
-call_shared
Link against dynamic libraries. This is only meaningful on platforms for which shared libraries are supported. This option is normally the default on such platforms. The different variants of this option are
for compatibility with various systems. You may use this option multiple times on the command line: it affects library searching for -l options which follow it.
-Bgroup
Set the "DF_1_GROUP" flag in the "DT_FLAGS_1" entry in the dynamic section. This causes the runtime linker to handle lookups in this object and its dependencies to be performed only inside the group.
--unresolved-symbols=report-all is implied. This option is only meaningful on ELF platforms which support shared libraries.
-Bstatic
-dn
-non_shared
-static
Do not link against shared libraries. This is only meaningful on platforms for which shared libraries are supported. The different variants of this option are for compatibility with various systems. You may use
this option multiple times on the command line: it affects library searching for -l options which follow it. This option also implies --unresolved-symbols=report-all. This option can be used with -shared. Doing
so means that a shared library is being created but that all of the library’s external references must be resolved by pulling in entries from static libraries.
-Bsymbolic
When creating a shared library, bind references to global symbols to the definition within the shared library, if any. Normally, it is possible for a program linked against a shared library to override the
definition within the shared library. This option is only meaningful on ELF platforms which support shared libraries.
-Bsymbolic-functions
When creating a shared library, bind references to global function symbols to the definition within the shared library, if any. This option is only meaningful on ELF platforms which support shared libraries.
-Bno-symbolic
This option can cancel previously specified -Bsymbolic and -Bsymbolic-functions.
--dynamic-list=dynamic‐list‐file
Specify the name of a dynamic list file to the linker. This is typically used when creating shared libraries to specify a list of global symbols whose references shouldn’t be bound to the definition within the
shared library, or creating dynamically linked executables to specify a list of symbols which should be added to the symbol table in the executable. This option is
