# 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_NPTL bool select LIBC_SUPPORT_THREADS_ANY config LIBC_SUPPORT_LINUXTHREADS bool select LIBC_SUPPORT_THREADS_ANY config LIBC_SUPPORT_WIN32THREADS bool select LIBC_SUPPORT_THREADS_ANY config LIBC_SUPPORT_THREADS_NONE bool config THREADS string default "nptl" if THREADS_NPTL default "linuxthreads" if THREADS_LINUXTHREADS default "win32" if THREADS_WIN32THREADS default "none" if THREADS_NONE || LIBC_none # No C library, no threads! 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 # !
