From 7fb980be2673097805afdd00aeeb2babd46753d7 Mon Sep 17 00:00:00 2001 From: Kerin Millar Date: Tue, 21 Sep 2021 07:55:42 +0100 Subject: sci-libs/tensorflow: build with -std=c++14 in 2.5.0-r1 TensorFlow is not yet compatible with the C++17 dialect. Allow it to build with gcc:11 by appending -std=c++14 to CXXFLAGS, prior to composing bazelrc. The flag doesn't encompass the building of the ruy library, so this is accompanied by a patch to include the header in the one place that ruy needs it. Filter out the -fvtable-verify=@(std|preinit) flag, if present. While ostensibly useful for hardening, it prevents TensorFlow from building successfully. Note that, while the pattern is in the form of an extglob, the accompanying shopt does _not_ need to be enabled. Have src_install localise "l", rather than "j", because the function in question never employs the latter.
