# C library options menu "C-library" config LIBC string 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" config LIBC_SUPPORT_THREADS_ANY bool config LIBC_SUPPORT_THREADS_NATIVE bool select LIBC_SUPPORT_THREADS_ANY config LIBC_SUPPORT_THREADS_LT bool select LIBC_SUPPORT_THREADS_ANY config LIBC_SUPPORT_THREADS_NONE bool config LIBC_PROVIDES_CXA_ATEXIT bool # C libraries should provide other values config THREADS string default "none" if THREADS_NONE if !

Note that the cross-ldd helper is not a full replacement for the native ldd. Please see the help, by running it with '--help' for more explanations. source "config.gen/libc.in.2" endif # !
