# C library options config LIBC string default "none" if BARE_METAL menu "C-library" config LIBC_VERSION string help Enter the date of the snapshot you want to use in the form: YYYYMMDD where YYYY is the 4-digit year, MM the 2-digit month and DD the 2-digit day in the month. Please note: - glibc has snapshots done every monday, and only the last ten are kept. - uClibc has daily snapshots, and only the last 30-or-so are kept. So if you want to be able to re-build your toolchain later, you will have to save your C library tarball by yourself. source config.gen/libc.in comment "Common C library options" config LIBC_SUPPORT_NPTL bool default n config LIBC_SUPPORT_LINUXTHREADS bool default n config THREADS string default "nptl" if THREADS_NPTL default "linuxthreads" if THREADS_LINUXTHREADS default "none" if THREADS_NONE choice bool prompt "Threading implementation to use:" default THREADS_NPTL if LIBC_SUPPORT_NPTL default THREADS_LINUXTHREADS if LIBC_SUPPORT_LINUXTHREADS && !
