I Hope they fix building firefox with GCC 7.1 before the switch.

The fix is in GCC 7.2

Huh? Firefox builds fine on Arch and that has been using gcc 7.1 for a while now. I don't see that they are using any special patches to firefox for that either.

I 100% agree, the main thing that made Ubuntu unique for desktop users, its the worst news for the linux community we have had in years

[shmerl]

So Debian is switching also?

It is not using gcc 7.1. It's using way newer 7.2 snapshot.

I'm wondering what they're going to do about the fact that installing GCC 7 breaks all clang++ compiles in C++17 mode because the latter lacks deduction guide support. That's going to be a little awkward until the new LLVM toolchain gets released and transitioned by Ubuntu too. I guess there's still time.

You can and should use libc++ instead of libstdc++ as C++ standard library with clang++.

I have no interest in building the entire LLVM toolchain on my local machines, let alone lobbying travis-ci to provide custom toolchains on their builders.

The ancient version of libc++ supplied on Ubuntu doesn't even compile with clang in C++14 mode , let alone C++17 mode.
