<p>Dear Dune developers,</p>
<p><br>
</p>
<p>also a big thank you from my side to everyone involved in the release process!</p>
<p><br>
</p>
<p>I tested with a standard Ubuntu 21.04, gcc 10.3.0, cmake 3.18.4 my Dumux setup that depends on the core modules, uggrid, alugrid, foamgrid, subgrid, opm-common and opm-grid. Everything is fine. Only opm-grid can't be configured currently:</p>

<p>Apparently, this needs to be resolved downstream, which is ok for us at the moment, as things still work with 2.7.</p>
<p><br>

<p>Kind regards</p>

<div class="PlainText">Hi,<br>
<br>
I want to give some feedback on the release candidate:<br>
<br>
Setup 1:<br>
- Linux Mint 20 Ulyana 64-bit, Kernel Linux 5.4.0-77-generic x86_64<br>
- GCC 9.3, CMake 3.16.3<br>
- external packages: GMP, QuadMath, TBB, SuperLU, SuiteSparse, ParMETIS, <br>
PkgConfig, Alberta, PTScotch, METIS<br>
- modules: amdis, dune-alugrid, dune-common, dune-foamgrid, <br>
dune-functions, dune-geometry, dune-grid, dune-istl, <br>
dune-localfunctions, dune-typetree, dune-uggrid, dune-vtk<br>
<br>
cmake warnings:<br>
- Policy CMP0087 is not set (I think we should fix this in the next release)<br>
- WARNING: could not find module 'dune-python', [...] 'dune-python' is <br>
suggested by dune-foamgrid<br>
<br>
c++ warnings:<br>
- dune-uggrid/dune/uggrid/gm/er.cc:1664:50: warning: iteration 4 invokes <br>
undefined behavior [-Waggressive-loop-optimizations]<br>
- dune-uggrid/dune/uggrid/gm/er.cc:1666:40: warning: iteration 4 invokes <br>
undefined behavior [-Waggressive-loop-optimizations]<br>
- dune-uggrid/dune/uggrid/parallel/dddif/debugger.cc:568:14: warning: <br>
ignoring return value of ‘int scanf(const char*, ...)’, declared with <br>
attribute warn_unused_result [-Wunused-result]<br>
- dune-uggrid/dune/uggrid/parallel/dddif/overlap.cc:727:22: warning: '0' <br>
flag used with ‘%p’ gnu_printf format [-Wformat=]<br>
<br>
C++ warnings (-Wall):<br>
- dune-uggrid: 100+ warnings about "comparison of integer expressions of <br>
different signedness", "var. maybe used uninitialized in this function", <br>
"static <function> defined but not used", "variable <var> set but not <br>
used",...<br>
- dune-common/dune/common/reservedvector.hh:70:5: note: variable <br>
tracking size limit exceeded with ‘-fvar-tracking-assignments’, retrying <br>
without (this I get a lot, but don't know what to do about it)<br>
<br>
<br>
Setup 2:<br>
- GCC 11.1, CXX_MAX_STANDARD=20<br>
<br>
c++ errors:<br>
- <br>
dune-grid/dune/grid/onedgrid/../onedgrid/onedgridleveliterator.hh:39:74: <br>
error: invalid declarator before ‘*’ token<br>
- <br>
dune-grid/dune/grid/onedgrid/../onedgrid/onedgridleveliterator.hh:39:74: <br>
error: expected ‘)’ before ‘*’ token<br>
- dune-grid/dune/grid/onedgrid/onedgridfactory.hh:58:5: error: <br>
template-id not allowed for destructor<br>
- dune-grid/dune/grid/onedgrid/onedgridfactory.cc:33:1: error: <br>
template-id not allowed for destructor<br>
<br>
c++-warnings:<br>
- dune-grid/dune/grid/io/file/dgfparser/dgfparser.cc:921:14: warning: <br>
arithmetic between floating-point type ‘double’ and enumeration type <br>
‘Dune::DuneGridFormatParser::orientation_t’ is deprecated<br>
- dune-grid/dune/grid/io/file/dgfparser/dgfparser.cc:947:30: warning: <br>
arithmetic between floating-point type ‘double’ and enumeration type <br>
‘Dune::DuneGridFormatParser::orientation_t’ is deprecated<br>
<br>
<br>
So, maybe we should fix the onedgrid errors that occur with -std=c++20. <br>
It is easy to fix. There just the template parameters on the constructor <br>
and destructor must be removed. Most of the warnings come from the <br>
dune-uggrid module. There is still a lot of cleanup necessary. This is <br>
not a quick fix.<br>
<br>
Best regards,<br>
Simon<br>
