Specifies the C++ library to use, and depends on whether or not any C++ using objects are created with ARM® Compiler 5.
is one of the following:
This is the default. Use this option to have the linker choose the C++ library based on the input objects. If there is at least one object that has been compiled by ARM Compiler 5 with C++ support or a C file that has been compiled with
--exceptionsthen the Rogue Wave C++ libraries are chosen. In all other cases libc++ is used.
Use this option to select the Rogue Wave C++ libraries.
Use this option to select the libc++ libraries.
NoteThe Rogue Wave C++ libraries are deprecated.
C++ objects compiled with
armclang and linked
armlink use libc++ by default. The
--stdlib=legacy_stdlib option must be used if Rogue Wave is required.
If C++ objects compiled with
armclang are mixed with C++ objects compiled with ARM Compiler 5, then
--stdlib=libc++ is required.
Compatibility between C++ libraries
The choice of C++ library at link time must match the choice of C++ include files at compile time for all input objects. In practice this means that C++ objects compiled with ARM Compiler 5 are only compatible with C++ objects compiled with ARM Compiler 6 using libc++ if they do not make use of the Rogue Wave C++ library.
