Neddys Notes to Self on the 17.0 Profile

What the 17.0 Profile Does

The 17.0 Profile depends on gcc-6.x, forces Position Independent Executables (pie) everywhere and breaks random things. Its far from stable and changes may be added/deleted/modified/reverted at any emerge --sync without warning

Position Independent Executables

That change breaks all the static libraries that are installed. I'm not aware of a command to rebuild static libraries but there probably will be one before the new profile goes stable.

I will be rebuilding @world because I'm doing other things with my Gentoo, just because I can.

Should I try the 17.0 Profile?

If you need to ask, No.

www-client/firefox-53.0.3 and mail-client/thunderbird-52.1.1 have know build issues with gcc-7.1 The work around is 

CXXFLAGS="${CXXFLAGS} -mno-avx" USE=custom-optimization emerge thunderbird firefox -av

with -O2 in make.conf See bug #617882.

This is not an issue with the 17.0 profile, its gcc-7.1 and the Mozilla install routines not working together.

Build Issues

Hopefully, there will patches or known workarounds (like don't use the gold linker) already.

dev-embedded/u-boot-tools-2017.05

Works with the bfd linker.

Oops. Its known broken with those new USE flags.

Builds with x86_64-pc-linux-gnu-6.3.0, so that's OK then.


sys-apps/openrc-0.17

This is no longer in the tree, so I get to keep the pieces.

What Works

The system works with the MATE desktop but its still early days.
