| # @BLURB: helper functions for packages using Boost C++ library |
| # @DESCRIPTION: |
| # Helper functions to be used when building packages using the Boost C++ |
| # library collection. |
| # |
| # Please note that this eclass does not set the dependencies for you. |
| # You need to do that yourself. |
| # |
| # For cmake & autotools it is usually necessary to set BOOST_ROOT using |
| # boost-utils_export_root. However, other build system may require more |
| # hackery or even appending -I$(boost-utils_get_includedir) to CFLAGS |
| # and -L$(boost-utils_get_libdir) to LDFLAGS. |

| # @DESCRIPTION: |
| # The maximal (newest) boost slot supported by the package. If unset, |
| # there is no limit (the newest installed version will be used). |
| |
| # @FUNCTION: boost-utils_get_best_slot |
| # @DESCRIPTION: |
| # Get newest installed slot of Boost. If BOOST_MAX_SLOT is set, the version |
| # returned will be at most in the specified slot. |

| # @FUNCTION: boost-utils_get_includedir |
| # @USAGE: [slot] |
| # @DESCRIPTION: |
| # Get the includedir for the given Boost slot. If no slot is given, |
| # defaults to the newest installed Boost slot (but not newer than |
| # BOOST_MAX_SLOT if that variable is set). |
| # |
| # Outputs the sole path (without -I). |

| # @USAGE: [slot] |
| # @DESCRIPTION: |
| # Get the libdir for the given Boost slot. If no slot is given, defaults |
| # to the newest installed Boost slot (but not newer than BOOST_MAX_SLOT |
| # if that variable is set). |
| # |
| # Outputs the sole path (without -L). |

| # @FUNCTION: boost-utils_export_root |
| # @USAGE: [slot] |
| # @DESCRIPTION: |
| # Set the BOOST_ROOT variable to includedir for the given Boost slot. |
| # If no slot is given, defaults to the newest installed Boost slot(but |
| # not newer than BOOST_MAX_SLOT if that variable is set). |
| # |
| # This variable satisfies both cmake and sys-devel/boost-m4 autoconf |
| # macros. |
