Hello Sam

As a simple user, can you explain to me or point me to a resource
about the link between Large File Support and time64 configuration ?

Thanks
Best regards

Hello Sam

Hi Mickaël,

As a simple user, can you explain to me or point me to a resource
about the link between Large File Support and time64 configuration ?

This is a good question -- the answer is two-fold:
1. glibc requires LFS to enable time64
2. Both can involve an ABI break if an off_t or time_t for example
are in an exposed structure, so it's best to do them at the same time.

But I've had second thoughts about this and I want to rethink
if we want to take this approach in the patch I sent.

I think we may want to do a hard-switch for defaults
instead in new profiles. I need to reflect on it a bit more.

Plans and notes are at https://wiki.gentoo.org/wiki/Project:Toolchain/time64_migration
if interested!

Thanks
Best regards

Best,
sam

As a simple user

And as another user...

... just in case anyone (else) needed to be sure, quoting from the above

For 32-bit arches <snip>

Obviously 64-bit arches are already fine.
