64 Bit Support

Support for building with 64 bit has been added.added. Please note that 32 bit builds are no longer supported. In order to obtain a 64 bit build, one has to configure the build to use a 64 bit compiler. This can be done during CMake configuration. This configuration step can be performed during CMake setup. For users with Visual Studio versions earlier than Visual Studio 2019 (version 16), make sure to select 'x64' as the optional platform for the generator during CMake configuration.

Doing this will automatically enable the CMake variable FEATSTD_64BIT_PLATFORM which is further used in Candera. If a 32 bit compiler is used, the CMake variable FEATSTD_32BIT_PLATFORM will be enabled automatically.

Two new types have been introduced for unsigned and signed integers which extend to the correct size when used in a 64 bit system or a 32 bit system. These are FeatStd::SizeType and FeatStd::OffsetType (equivalent to std::size_t type and std::ptrdiff_t types).

The API has been adapted at various locations to use FeatStd::SizeType and FeatStd::OffsetType instead of integer types. Application code using a previous version will be compatible due to implicit integer conversion. Please take care on compiler warnings related to type conversions, alignment casts and signed/unsigned comparisons.
