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.

This selects the native threads implementation for the selected

system and C library.

For example, on Linux with glibc, this is NPTL; on Windows with

mingw, this is win32.

Say 'Y' here if you want to have a ldd-like helper that
|
|
you can run on your build system, and that will (try to)
|
|
resolve shared libraries dependencies as if run on the
|
|
target.
|
|
|
|
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.
