[gdal-dev] Call for discussion on RFC68: C++11 compilation mode

Hi all,

just want to share with you that we've got the same discussion recently in the orfeo toolbox project and we finally decide to move directly to c++14 in the next release (6.2). It is a more recent standard with for sure less new features than in c++11 but yet useful. Moreover it does not change a lot the minimum compiler version (gcc min version is 4.9 I think for c++14).

Will be glad to exchange also with you on strategies, pro/cons to then modernize the code.

You can find more information about the discussion about c++11 vs c++14 and few experiments which have been made with clang-tidy for OTB in the following RFComments and RFChanges:



my 2 cents.

Hi Tamas,

Unless I'm mistaken your gisinternals.com builds don't include MSVC 2015 currently. Right ? Do you have any plans to do so ? Currently the GDAL AppVeyor target uses SDKSs from gisinternals to do builds with a number of third-party libraries.
