We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
* Initial attempt at flann packaging.
Python2 somehow works. Python3 does not. Still debugging their
obscure setup.py configuration.
* Flann good enough. Python3 broken but close.
Flake8 checks in place. Unsure about CMAKE_BUILD_TYPE and default
spack behavior.
* spack uses RelWithDebInfo as default build type.
* builds py2/3, but direct site-packages install
* prefix working, empty python install dir
* flann package +python installs correctly
* str format {0} instead of {}
* potential doctest fix
* consistency of build env with PythonPackage
* fix python again, test deptype todo, build type
* potentially enable matlab, untested
