11 | *Allowed values*: `98`, `03`, `0x`, `11`, `1y`, `14`, `1z`, `17`, `2a`, | |
12 | `latest`. | |
13 | + | |
14 | Specifies the version of the C++ Standard Language to build with. All the | |
15 | official versions of the standard since "98" are included. It is also possible | |
16 | to specify using the experimental, work in progress, `latest` version. Some | |
17 | compilers specified intermediate versions for the experimental versions leading | |
18 | up to the released standard version. Those are included following the GNU | |
19 | nomenclature as `0x`, `1y`, `1z`, and `2a`. Depending on the compiler `latest` | |
20 | would map to one of those. | |
21 | ||
22 | NOTE: This is an `optional` feature. Hence when not specified the compiler | |
23 | default behaviour is used. | |
24 | ||
25 | NOTE: Please consult the toolset specific documentation for which `cxxstd` | |
26 | is supported. | |

36 | [[bbv2.builtin.features.cxxstd-dialect]]`cxxstd-dialect`:: | |
37 | *Subfeature of* `cxxstd` | |
38 | + | |
39 | *Allowed values*: `iso`, `gnu`, `ms`. | |
40 | + | |
41 | Indicates if a non-standard dialect should be used. These usually have | |
42 | either/or extensions or platform specific functionality. Not specifying the | |
43 | dialect will default to 'iso' which will attempt to use ISO C++ Standard | |
44 | conformance to the best of the compiler's ability. | |
