# newlib options # depends on BARE_METAL config LIBC_newlib help Newlib is a C library intended for use on embedded systems. It is a conglomeration of several library parts, all under free software licenses that make them easily usable on embedded products. Newlib is only available in source form. It can be compiled for a wide array of processors, and will usually work on any architecture with the addition of a few low-level routines. choice bool prompt "newlib version" # Don't remove next line # CT_INSERT_VERSION_BELOW config LIBC_NEWLIB_V_1_18_0 bool prompt "1.18.0 (EXPERIMENTAL)" depends on EXPERIMENTAL config LIBC_NEWLIB_V_1_17_0 bool prompt "1.17.0" config LIBC_NEWLIB_CVS bool prompt "Use CVS snapshot" help The newlib "team" rolls new releases about once a year (december).
