Fails to build with Boost 1.74 (error: static assertion failed: Const/reference qualifiers on Karma rule attribute are meaningless) #236

Closed sebastic closed 3 years ago

sebastic commented 3 years ago

As reported by Anton Gladky in Debian Bug #975593:

it was discovered that your package failed to build against boost_1.74. Logs can be found here [1]. Most relevant part is probably this:

/usr/include/boost/spirit/home/karma/nonterminal/rule.hpp:140:9: error: static assertion failed: Const/reference qualifiers on Karma rule attribute are meaningless
  140 |         BOOST_STATIC_ASSERT_MSG(
      |         ^~~~~~~~~~~~~~~~~~~~~~~
error: command '/usr/bin/c++' failed with exit code 1

It is planned to push boost_1.74 as the default version in Debian/Bullseye.

boost1.74 is now the default in Debian unstable, increasing the severity of this issue.

This is fixed in Mapnik 3.0.24.
