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.
