After emerging dev-cpp/abseil-cpp-20230125.2, my system tries to rebuild gdal, and fails with: <snip ... > /usr/bin/x86_64-pc-linux-gnu-g++ -DDONT_DEPRECATE_SPRINTF -DGDAL_COMPILATION -DHAVE_AVX_AT_COMPILE_TIME -DHAVE_SSE_AT_COMPILE_TIME -DHAVE_SSSE3_AT_COMPILE_TIME -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/apps -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/alg -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/gcore -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3_build/gcore -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/port -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3_build/port -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/frmts -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf -I/var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/generic -std=c++14 -fvisibility=hidden -fPIC -Wall -Wextra -Winit-self -Wunused-parameter -Wmissing-declarations -Wlogical-op -Wshadow -Wmissing-include-dirs -Wformat -Werror=format-security -Wno-format-nonliteral -Werror=vla -Wno-clobbered -Wdate-time -Wnull-dereference -Wextra-semi -Wfloat-conversion -Wnon-virtual-dtor -Woverloaded-virtual -Wsuggest-override -fno-operator-names -Wzero-as-null-pointer-constant -std=c++11 -MD -MT ogr/ogrsf_frmts/flatgeobuf/CMakeFiles/ogr_FlatGeobuf.dir/geometrywriter.cpp.o -MF ogr/ogrsf_frmts/flatgeobuf/CMakeFiles/ogr_FlatGeobuf.dir/geometrywriter.cpp.o.d -o ogr/ogrsf_frmts/flatgeobuf/CMakeFiles/ogr_FlatGeobuf.dir/geometrywriter.cpp.o -c /var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf/geometrywriter.cpp In file included from /usr/include/absl/base/config.h:86, from /usr/include/absl/base/attributes.h:37, from /usr/include/absl/strings/string_view.h:39, from /var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf/flatbuffers/base.h:237, from /var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf/flatbuffers/array.h:20, from /var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf/flatbuffers/flatbuffers.h:22, from /var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf/feature_generated.h:6, from /var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf/geometrywriter.h:35, from /var/tmp/portage/sci-libs/gdal-3.6.3/work/gdal-3.6.3/ogr/ogrsf_frmts/flatgeobuf/geometrywriter.cpp:29: /usr/include/absl/base/policy_checks.h:79:2: error: #error "C++ versions less than C++14 are not supported." 79 | #error "C++ versions less than C++14 are not supported." | ^~~~~ /usr/include/absl/strings/string_view.h:52:26: error: 'string_view' in namespace 'std' does not name a type 52 | using string_view = std::string_view; | ^~~~~~~~~~~ /usr/include/absl/strings/string_view.h:52:21: note: 'std::string_view' is only available from C++17 onwards 52 | using string_view = std::string_view; | ^~~ <snip ... > The build system doesn't allow me to override the -std=c++11 CXXFLAGS (I've tried, without success).

Expected Results: sci-libs/gdal should explicitly depend on dev-cpp/abseil-cpp

Created attachment 860428 [details, diff] Fix build with the new abseil Added -std=c++-17 flag for the flatgeobuf plugin.
I can confirm this. It looks like abseil-cpp being an automagic dependency in gdal-3.6.3 as well. At least it's not listed in the ebuild, nor have I noticed it in the configuration output, grepping for abseil and absl.

The error happened in a file which seemed related to flatbuffers from it's naming.
