Clang defines __GNUC__ to 4, as that represents its level of
support for the GNU C dialect. The gcc compiler does not provide
a macro indicating the compiler separately from the dialect supported.
We must therefore use the __clang__ macro to avoid false positives.
since we still support g++-7, where filesystem is marked experimental,
we introduce a wrapper header and expose the namespace to use
as Opm::filesystem.
for gcc we unconditionally link with libstdc++fs in the python bindings.
the setup.py stuff links as c code, not c++ code, so it is not
automatically added on any gcc version. this might prove unportable
later.
Mostly for converting between std::time_t and broken-down time
stamps. Uses UTC and std::chrono::system_clock. May wrap in as
little as 292 years, depending on the period of system_clock.
Intended to replace various timestamping utility functions from
libecl. A comprehensive time-service protocol for Flow is much more
work than this, and will likely not be easily realized before we
have C++17 and its much expanded time/calendar library.
calculated and stored as private data members in EclipseGrid.
The API for the class is unchanged except for some minor changes for exportACTNUM, exportZCORN and exportCOORD.
These changes have triggered some very few modifications in the opm-grid and opm-simulators repo.
These classes are only used by opm-material and its downstreams. The
reason for doing moving it there is that this allows more freedom in
reorganizing the lower-level OPM modules (i.e., opm-common,
opm-parser, opm-output) while still avoiding a hard dependency of the
thermodynamic and numerical framework modules on the ECL file parsing
libraries.
