Compiler Command-line Options
2.1.71 --library_interface=lib
This option enables the generation of code that is compatible with the selected library
type.
Syntax
--library_interface=lib
Where lib is one of:
rvct
aeabi_clib90
aeabi_clib99
aeabi_clib
aeabi_glibc
Specifies that the compiler output works with the RVCT runtime
libraries.
Specifies that the compiler output works with any ISO C90 library
compliant with the ARM Embedded Application Binary Interface
(AEABI).
Specifies that the compiler output works with any ISO C99 library
compliant with the ARM Embedded Application Binary Interface
(AEABI).
Specifies that the compiler output works with any ISO C library
compliant with the ARM Embedded Application Binary Interface
(AEABI).
Selecting the option --library_interface=aeabi_clib is
equivalent to specifying either --library_interface=aeabi_clib90
or --library_interface=aeabi_clib99, depending on the choice of
source language used.
The choice of source language is dependent both on the
command-line options selected and on the filename suffixes used.
Specifies that the compiler output works with an
AEABI-compliant version of the GNU C library.
Default
If you do not specify --library_interface, the compiler assumes
--library_interface=rvct.
Usage
• Use the option --library_interface=rvct to exploit the full range of compiler and
library optimizations when linking.
