Fedora's FESCo Makes A Bold Move To Try To Release Fedora 22 On Time

[gilboa]

Correct, Fedora 22 will ship with gcc-5, and any packages which have been updated after gcc-5 was added will be build with gcc-5, the only thing which will not happen is to use c++-11
mode when building c++ code. gcc will support c++-11 mode, but the distro c++ packages will not be build with it, as that would require a mass rebuild.

Michael can you please update the article to reflect this, the current article is a bit misleading.

As far as I see (fedora-devel), mass rebuild request was denied.
Without it, pushing gcc 5.0 is crazy talk (I maintain a couple of packages written in C++).

You sure? Do you have a link?

But I think they will ship the 5.0 compiler just not every package compiled with 5.0 right?

There seems to be an ABI change regarding c++11, which to my understanding means that libraries (or programs) (using c++1) that were built with older GCC version will not work together with programs (or other libraries) built with GCC 5.

Just delay it, delaying is common practice and could lead to other things being better tested.

Who does really care about this? for a desktop user I dont see any benefit from gcc 5.0. Maybe its important for C developers? But I think they will ship the 5.0 compiler just not every package compiled with 5.0 right?

I shurly am only ignorant but could somebody tell me why?

The changelog says it optimizes Firefox a lot better. That ought to be user-visible, and likely includes all other big C++ apps/libs.

Its not like with python where you need all dependencies portet to a new version before you can port your programm.

F21 took forever to come out, but it was well worth the wait. I understand that GCC5 is a bit unrealistic for a May release, but hardened builds are an important security feature and I wouldn't mind waiting a few weeks longer to have them. Just my 2 cents.

Was it? I was more having a This Better Be The Bloody Last Time feeling. I mean, don't get me wrong, I'm happy the release did come out. F20 just started approaching the point of unusably old before F21 ever came out. I hope F22 to come out without many delays so F20 can finally be put out of maintenance soon

As a user I much prefer a feature-rich release that's a few weeks late. Always having the latest toolchain is one of Fedora's main selling points.

They also played around with the concept of tic-toc releases. Fedora 22 would be the stability release while Fedora 23 would be the bleeding-edge release

Fedora should be more milestone based.

I'm not sure I care what compiler they ship, it is more a desire to see them ship what they say they will sip and not get hung up on a date. Maybe 23 will be all GCC 5 built, it would be nice but I'd rather see the transition done right than to try to nail a date. I don't see any signs that they intended to ship 22 with GCC 5.
