Subject: [PATCH] Use old boost::optional implementation for boost 1.61
|
|
|
|
Fixes #777
|
|
|
|
- boost::spirit v 1.61 relies on the fact that the `Variant` template
|
|
type of `boost::spirit::qi::detail::find_substitute` typedefs a
|
|
`types` subtype.
|
|
- For the failing instantiation of `find_substition` a
|
|
`boost::optional` is used as `Variant` template type.
|
|
- `boost::optional` removed its `types` subtype implementation with
|
|
commit [boost::optional b5b8414c0], which means that this type is
|
|
missing on every boost version 1.61 and onwards (until fixed of course).
|
|
- Using the BOOST_OPTIONAL_CONFIG_USE_OLD_IMPLEMENTATION_OF_OPTIONAL
|
|
reenables the old implementation of boost::optional, which provides a
|
|
`types` subtype.
|
|
|
|
This commits enables said define for boost 1.61 only, because I consider
|
|
this an upstream bug. The upstream bug is tracked as [boost #12349].
