# @BLURB: helper functions for packages using Boost C++ library |
| 14 |
# @DESCRIPTION: |
| 15 |
# Helper functions to be used when building packages using the Boost C++ |
| 16 |
# library collection. |
| 17 |
# |
| 18 |
# Please note that this eclass does not set the dependencies for you. |
| 19 |
# You need to do that yourself. |
| 20 |
# |
| 21 |
# For cmake & autotools it is usually necessary to set BOOST_ROOT using |
| 22 |
# boost-utils_export_root. However, other build system may require more |
| 23 |
# hackery or even appending -I$(boost-utils_get_includedir) to CFLAGS |
| 24 |
# and -L$(boost-utils_get_libdir) to LDFLAGS. |

| 86 |
# not newer than BOOST_MAX_SLOT if that variable is set). |
