some existing COMPILER lines with arch restrictions etc. In the usual
case this is now using "COMPILER = base-clang ports-gcc base-gcc" on
ports with c++ libraries in WANTLIB.
This is basically intended to be a noop on architectures using clang
as the system compiler, but help with other architectures where we
currently have many ports knocked out due to building with an unsuitable
compiler -
- some ports require c++11/newer so the GCC version in base that is used
on these archirtectures is too old.
- some ports have conflicts where an executable is built with one compiler
(e.g. gcc from base) but a library dependency is built with a different
one (e.g. gcc from ports), resulted in mixing incompatible libraries in the
same address space.
devel/gmp is intentionally skipped as it's on the path to building gcc -
the c++ library there is unused in ports (and not built by default upstream)
so intending to disable building gmpcxx in a future commit.
The purpose of this library is to provide:
* An extensible framework that will support robust spatial indexing
methods.
* Support for sophisticated spatial queries. Range, point location,
nearest neighbor and k-nearest neighbor as well as parametric queries
(defined by spatial constraints) should be easy to deploy and run.
* Easy to use interfaces for inserting, deleting and updating
information.
* Wide variety of customization capabilities. Basic index and storage
characteristics like the page size, node capacity, minimum fan-out,
splitting algorithm, etc. should be easy to customize.
* Index persistence. Internal memory and external memory structures
should be supported. Clustered and non-clustered indices should be
easy to be persisted.
