Hi, Happy New Year!
I propose we update our build requirement from C++11 to C++17. This should hopefully be unnoticed by anyone using a not too antiquated build chain.
Initial trigger for this move is explained in https://github.com/OSGeo/PROJ/pull/4366. All our existing CI configurations already satisfy the C++17 requirement (and one of them was already testing C++20 compatibility)
I don't anticipate much use of new capabilities for now except perhaps replacing our internal::make_unique<> by C++14 std::make_unique<>
C++17 has been a build requirement for GDAL since one year and nobody complained. Cf https://gdal.org/en/stable/development/rfc/rfc98_build_requirements_gdal_3_9.html for an analysis of the impacts.
This also satisfies https://proj.org/en/stable/community/rfc/rfc-3.html which mentions "Keeping a policy of always lagging behind be two iterations of the standard is thought to be the best comprise between the two concerns", given that C++20 and C++23 are out.
Even -- http://www.spatialys.com My software is free, but my time generally not. Butcher of all kinds of standards, open or closed formats. At the end, this is just about bytes. _______________________________________________ PROJ mailing list PROJ@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/proj
